M.I. Rochev, A.Ya. Fedorov, D.V. SerebrjakovOn the complex approach to water supply and water disposal systems designing (by the example of the city of Smolensk)

The situation currently formed in the city of Smolensk in the sphere of watersupply and water disposal systems is presented. It is showed that for the city with significant elevations drops it is necessary for water supply system to be zoned. The presence of the only one general zone in the city when the provision of the required pressure in high blocks of flats is carried out by massive construction of swap stations brings to the situation when due to the extreme pressure in the lower part of the city the premature wear of networks and frequent emergency situations occure. And at the same time in areas with increased relief marks the water pressure is not sufficient. The measures which are necessary for provision of uninterrupted work for watersupply and water disposal networks in conditions of the city development are listed. The scheme of the city wastewater treatment plants reconstruction providing the achievement of current requirements to the degree of wastewaters treatment is described.

Qi yong Yang, J ihua Chen, F eng ZhangControl of membrane pollution in immersed membrane bioreactors with the porous floating load

Membrane pollution is the main obstacle for wide spread occurrence of membrane bioreactors (MBR). The article represents the investigation on efficiency of the hybrid membrane bioreactor (HMBR) with the porous floating load with regard to membrane pollution and particular to formation of yellow cake layers on the membrane surface. For investigation of suspended material effect on filtration characteristics of HMBR the parallel trials of two types of reactors (MBR vs. HMBR) were conducted. In the course of the short-term trial the critical flow of HMBR increased to 20% whereas cake's resistance in HMBR decreased to 86% in comparison with MBR. During long-term trials the level of pressure increasing on suction in HMBR was only 30% of this indicator for MBR showing that the pollution degree of membrane was significantly lower than for MBR. These experimental observations point to the fact that biomass suspended materials play a huge role in processes of filtration and decreasing of pollution resistance. For better understanding of the suspended materials effect on the system operational characteristics the influence of following properties were investigated: cake layers on membrane surface, characteristics of sludge mixture, filterability of clarified water and activated sludge suspensions.

YU.N. Kirichenko Drinking water and public health of the Kursk region

The data on deterioration of the Kursk region surface waters are presented; it proves the degradation of wastewater treatment plants work and unsatisfactory organization of sanitation and cleaning service. The hydrogeological specification of underground water levels is presented. It is showed that it is human economic activity that to a quite large extend causes a bad effect on underground waters as well as on other elements of geological environment that is clearly seen in areas of the largest concentration of industrial enterprises, in the places of storage of liquid and solid wastes. Among pollutants in underground waters petroleum products, nitrogen compounds, heavy metals chloride dominate. The data on discrepancy of origin quality of underground water level water used for water supply of all 28 areas of the Kursk region to hygienic requirements according to the total alpha-activity that is showed by the content of natural isotopes Ra228 и Ra226 in them which are the main dose-forming radionuclide. The statistics of oncological diseases in the Kursk region can be explained by this fact.

M. Gomez, F. Plaza, G. Garralon, J. Perez, M.A. Gomez Comparative study of physical and chemical methods of purification and disinfection of wastewater and ultrafiltration

The comparative investigation of economical expenses and purified water quality which was obtained by using combination of physical and chemical treatment with ultraviolet disinfection and combination of filtration through granular filling and ultrafiltration at the stage of city wastewaters tertiary treatment was carried out. For this investigation the system of physical and chemical city wastewaters treatment with ultraviolet disinfection was developed. The preprocessing of water was in the coagulation of aluminum sulfate which dose was 100 mg/l, clarification on the layer of suspended sludge (0,8 m3/m2ph) and filtration through sand filter (5,0 m3/m2ph). Ultrafiltration module was equipped with flat polyvinylidene fluoride membranes (pore size 0, 5 microns) and tertiary treatment was carried out in sand pressure filter (8, 0 m3/m2ph). In both systems the purified water of perfect quality was obtained. It met the standards both of physical-chemical (removal of 91 % of suspended materials and 99% of water turbidity) and microbiological (total absence of nematode eggs, coliform bacteria, E.coli and coliphages) indicators. However, though in both cases physical-chemical indicators quality was stable it was discovered that during ultraviolet disinfection the microbiological content of purified water depends on quality of water which is processed, especially in those aspects that concern the transmittance coefficient of the ultraviolet radiation. In contrast, using membrane technology the microbiological content of purified water remained stable. Other control parameters, for example, analysis of the particle distribution by size confirmed a higher quality of water purified by ultrafiltration in comparison with the water treated by physical-chemical method with ultraviolet disinfection. As to economical point of the issue so both technologies are characterized with similar operating costs when the level of capital costs in case of membrane technology applying exceeded the corresponding indicator of the physical-chemical treatment and ultraviolet disinfection twice, that was firstly caused by the high cost of membrane equipment installation.

V.P. Kargapolcev, O.A. Mickevich, A.A. Sidenko On verification of water meters and flow meters used in the housing and communal services

Metrological base for verification of water meters and flow meters from the group of heat meters (first of all - torrential units) in most cases are either absent or became obsolete and requires improvements. Hence, for the last years a number of domestic manufacturers have organized the production of torrential units with different levels of automation. In the process of such units operation the question and problems concerning the features of unit models and their applicability for verification of different types of equipment unavoidably occurred. All occurred problems relating to the reason of their occurrence can be divided into 3 groups: faults of unit manufacturers; problems appearing due to the unit owner blame; and complications appearing due to the guilt of manufactures of water meters and flow meters intended to the verification. For providing the verification of water meters and flow meters from the group of heat meters used in the housing and communal services, OKB “Gidrodinamika” has developed torrential calibration rig UPSG-50 (УПСЖ-50) and has been producing it for the last years.

S.M. Asadov, A.M. AlievProperties of heavy metal ions of oil reservoir water

The chemical composition of Apsheron oil and reservoir waters, concentration of heavy metals in them and ions properties were investigated. It was found out that type and amount of heavy metal within the crude oil and reservoir waters from industrial settlement Neft Daşları depend on depth and horizon of the well. Equilibrium properties of heavy metal ions in reservoir waters in frames of Debye–Hückel limiting law were studied. Their activity concentration and coefficient were defined with regard to ionic strength and particles stability constants for complexes and products including toxic ions of heavy metals containing in reservoir waters. The obtained data on heavy metals ions properties can be used in development of technology of oil and reservoir waters treatment from dangerous and toxic substances.

O.V. Arapov, E.A. Kopylova, S.E. Ivanov, S.A. Sobol, V.V. LegunThe use of "Ferroksin" reagent for electroplating wastewaters treatment

Advantages of water treatment ferrate technology based on using oxidants of sodium and potassium ferrates as reagents were represented. These reagents have unique properties: along with oxidizing action they can also facilitates coagulation and disinfection processes. The wide use of this treatment method was constrained due to the absence of ferrates industrial synthesis methods. At CJSC “NPO EKROS” the industrial production technology of the new reagent “Ferroksin” which main active substance is a strong oxidant – sodium ferrate in the degree of iron oxidation (+6) – was developed. At wastewater treatment plants of JSC “Krasniy Oktjabr’ ” the joint trials on processing of different electroplating wastewaters using “Ferroksin” reagent were conducted. The use of “Ferroksin” reagent for electroplating wastewaters treatment is quiet promising not only as an oxidant but also as a coagulant.

Brian Bolto The interaction of chlorine with flocculants in water treatment: Review

Polyelectrolytes used in water treatment as flocculants either independently or along with mineral coagulants can interact with oxidants used for disinfection; moreover, forming by-products are similar to those substances which appear as a result of reaction between chloride and natural organic substances. The references review shows that at standard concentration of cationic flocculants and chloride usually used for water treatment the formation of trihalomethanes is minimal; and polymer is not the main cause of these compounds formation. In those cases when using flocculant the level of by-product formation appeared to be unacceptably high, as a rule other products contained in the commodity product were identified as their derivatives. The most important among them was acrylamide residual monomer. At the thorough quality control of containing monomer the trihalomethanes formation is insignificant. However, other by-products should be the subject of further investigation. For example, the sum of organic compounds forming from polyamides is 192 μg /l. In case of poly diallyl dimethyl ammonium chloride the level of their formation is significantly lower (12 μg /l)/. It is also announced that another substance that can be formed during chlorination is nitrosodimethylamine limited number of which is formed at work with cationic flocculants, however, its containing becomes considerable only at presence of other nitrogenous compounds. It is necessary to have a large amount of data concerning cationic polyacrylamides on which as it is stated the proper attention has not been paid so far. In particular, this concerns the possible contribution of the monomer cation acrylate. Neither anionic nor nonionic polyacrylamides form significant number of thrihalomethanes. Contribution of such polymers on formation of chlororganic compounds is equal to containing residual monomers. Thus, the selection of the most appropriate polymer should be carried out in accordance with performance process indicators and paying a special attention to absence of low-molecular compounds in it. For this reason it is necessary to conduct a thorough control of containing of monomers and admixtures within a polymer.

I.G. Shaihiev, G.A. MinlegulovaIndustrial waste water treatment by wastewaters of other industries. Part 1

Using wastewaters of one industry for wastewater treatment of another industry, the pollutants which are contended in the first wastewaters are chemical reagents for removal and neutralization of toxic admixtures of the second ones. In this case the process of wastewater treatment by different chemical and physical-chemical methods is replaced by simple wastewaters mixing, but surely in certain proportions. The article represents methods of joint treatment of different origin wastewaters by means of reactions of neutralization, oxidation, regeneration as well as processes of coagulation, flocculation, complexation, chemisorption with emission of admixtures interaction products in the form of solid disperse phase.

P. Huang, S. Qin, Q. Zhao, X. GuoOperational commissioning of sewage treatment plants in Mudanjiang. Factors effecting phosphorus removal

The successful conduction of adjustment work at wastewater treatment plants is the key event both for its further use and for the achievement of efficient phosphorus removal. After completion of wastewater treatment plants construction in the city of Mundanjiang (Heilongjiang province, China) with a performance of 100 000 m3 per day, the new method of operational commissioning of wastewater treatment plants with continuous wastewater feed for plants was tested. The method differs from the traditional method of operational commissioning in adding of imported active sludge in an aerotank during the unsteady feed of wastewaters. The active sludge grows directly in the aerotank without adding the sludge from other wastewater treatment plants. After a month use in the regime of adjustment the sludge dose increased to 2, 5 kg/m3 while the sludge index increased to almost 80% that proves a fast and easy operational commissioning to performance indicators. After the successful operational commissioning the investigation of phosphorus removal was conducted while the special attention was paid to such factors as oxidation-reduction potential (ORP) and nitrate/nitrite azote. With alteration of aerobic and anaerobic regimes in the aerotanks the efficiency of phosphorus removal may reach 80%. Experiential results showed that in the anaerobic zone the critical levels for biological removal of phosphorus are: ORP – 140 mV, nitrate azote 2 mg/l while optimal conditions for phosphorous removal in the aerotanks are: dissolved oxygen content in the aerobic zone at the level of 1, 7 – 2, 5 mg/l; BOD5/ Rcom – 20-30, sludge index at the level 70-80 and sludge age of 5 days.

S. Sayed, S. Tarek, I. Dijkstra, C. MoermanOptimal mode of capillary nanofiltration elements for waste water treatment

Direct capillary nanofiltration is a new method used for the single step surface waters treatment for water supply aims as well as wastewaters without preprocessing. Membrane module of DCNF combines the best qualities of capillary membranes of ultrafiltration and nanofiltration that is showed in attitude of removal of dissolved organic carbon, color of water, bacteria, viruses and pesticides from water. The method of direct capillary filtration was used for single-step treatment of Twente Canal surface waters in Netherlands. In this work the method of the direct capillary nanofiltration was used (for the first time) for wastewater treatment in conditions of continuous and stable performance. The important work aspect was the definition of optimal regime for the pilot plant use. The defined optimal conditions are the following: filter cycle - 15 minutes, flow rate of undiluted household wastewaters – 20 l/m2 per hour. The filtration can be conducted continuously providing a stable performance of about 8 hours. Then the plant should be exposed to chemical treatment as a result of membrane modules pollution. During the nanofiltration the significant retentivity is reached by such quality indicators as COD, BOD, content of iron and phosphate, total number of bacteria and a bit worse indicators concerning manganese retention while ammonium removal level appeared to be extremely low.

Microbiology

E.V. PleshakovaGenetic analysis of microbial consortia of model equipment for treatment of wastewaters containing sulphonol; perspective of its practical use.

It is found that the process of sulfinol destruction in Рseudomonas cepacia stains selected from the consortia structure of model purification equipment is controlled by the plasmid pSf1 (54 kbp), in Р. Aeruginosa strains – by plasmid pSf2 (4,3 kbp). Both plasmids determinate the first stage of sulphonol biodegradation which is the desulfonation. It is showed that changes of the consortium plasmid profile which provide the sulphonol destruction represent the variation of number and proportion of bacterial spices that make a microbial community. The developed methods of plasmid screening of consortia destructing anionic surfactant are recommended for supervision of wastewater treatment plants work.

Ecology and hydrology of water reservoirs

L.A. Margarjan, S.G. Minasjan, G.P. Pirumjan Comparison of the Canadian and the Specific Combinatorial indexes of water quality in the estimation of the river Razdan pollution density

The comparison of the Canadian and Specific Combinatorial water quality indexes of the river Razdan was carried out using standards for fishing areas and requirements for drinking water supply sources. The level of the river pollution density was defined from its source to the mouth on the basis of 31 hydrochemical indicators during 2005-2007 years. According to obtained information, the upstream by fishery management standards belongs to the middle III (polluted) grade, by drinking water supply requirements – to II (weakly polluted) grade while the downstream belongs to the IV (dirty) and III (polluted) grades. The most polluted section in the river is observed in the point №55 – lower the city of Yerevan where the extremely high anthropogenic impact was detected. It is discovered that both water quality indexes are equal in complex river estimation by hydrochemical indicators in terms of fishing areas standards and drinking water supply sources requirements and can be both used for estimation and investigation of river water quality.

S.M. Musaeljan, A.B. Petrosjan Some aspects of the thermal regime of the Volgograd reservoir and its impact on the environment

Some aspects of the Volgograd reservoir thermal regime such as spring and autumn homothermy, temperature jump or metalimnion, water surface temperature change during the year are presented in the article. The reservoir effect on precipitation regime in the coastal area is showed. The reservoir effect on precipitation regime expresses in a fact that there is less precipitation over the water than on the land in the warm season. In the Volgograd reservoir conditions for years of observation there was on average 10% less precipitation over the water than on the land. Water surface area increasing led to the growth of relative and absolute air humidity. Near the Volgograd reservoir the increasing of absolute air humidity for 8-10 % is recorded at the distance of 4-6 km from the shore, and difference in the relative air humidity in a dry season increases to 15-20%. The establishment of the Volgograd reservoir led to the significant increase of wind speed and frequency. The wind speed over the reservoir in comparison with the speed over the land increased approximately in 1, 2 times; a breeze type of air appeared on the coastal area: at day it blows from the reservoir to the coast, at night – from the coast to the reservoir. The overregulation of the river Volga’s flow caused by the Volgograd reservoir made considerable changes in terms of incoming of autumn and spring ice phenomena.

V.P. Kargapolcev, A.A. SidenkoVerification of water meters - "for" and "against"

The issue of housing water meters verification was observed. The replacement of water meters to the new ones after calibration interval completion is more advantageous for civilians rather than their verification; it is enough to carry out a compulsory verification for adjustment of equipment calibration interval in a limited extent by local bodies of Federal agency on technical regulation and metrology (Rostandart).

Wastewater treatment

I.G. SHaihiev, G.A. Minlegulova Industrial wastewater treatment by wastewater of other industries. Part 2. Wastewater treatment of electroplating industry.

Using wastewaters of one industry for wastewater treatment of another industry, the pollutants which are contended in the first wastewaters are chemical reagents for removal and neutralization of toxic admixtures of the second ones. In this case the process of wastewater treatment by different chemical and physical-chemical methods is replaced by simple wastewaters mixing, but surely in certain proportions. The electroplating wastes treatment is characterized by use of a large number of expensive reagents that makes a process economically inefficient. But in the same time the formation of acidic and alkaline wastewaters at electroplating industries makes their joint treatment more prospective. The article represents different examples of treatment by different industries wastewater mixing of chromiferous and cyano-containing electroplating wastewaters as well as wastewaters of electroplating and etching industries containing heavy metals ions.

I. A. Nechaev, L.V. GandurinaStatus and prospects of flocculants use for coagulation wastewater treatment intensification. Part 1. The use of flocculants along with inorganic coagulants

The advantages and features of joint application of flocculants and coagulants for wastewater treatment are listed. The data of reagent optimal dose and its effect in wastewater treatment of different composition are represented. It is showed that the joint applications with coagulant the high-molecular low-charged non-ionic and weakly anionic flocculants are most efficient. As a rule the process of flakes consolidation by adding flocculants is carried out by bridging mechanism and depends on flocculant molecular mass rather than on its charge. During the treatment of multicomponent wastewaters flocculants play a leading role and by controlling a dose and choosing a flocculant type the efficiency of wastewater treatment with its joint application with coagulant can be significantly increased. In this case, the composition of dissolved admixtures in choosing flocculants and their doses have a first-rate importance.

V. G. Voskonjan, A. V. VoskonjanTreatment of surface wastewaters by using mussel aquaculture

The self-cleaning function of water reservoirs from pollution of surface wastewaters are best performed by mussels. The most efficient of mussel’s species are bivalve mollusks: mussels, long-necked clams and oyster and others as well as epischura baikalensis which provides cleaning of the lake Baikal. The most assessable mollusks for the surface waters biotreatment are mussels. Mussels are stenophagous and eat organic particles suspended in the water in a large amount among which the most significant for their food is a microalga that is a phytoplankton. It is necessary to organize settling ponds and settle them with mollusks because mussels play role of a biofilter and provide the increasing of treatment quality. It is necessary for mussels to grow in the special mussel’s cells in a water reservoir to put the biofilter on work.

M.M.Asadov, M.M.TalybovKinetic conditions of salt formation in the system of aqueous solution of salt - inhibitor

In the frames of phenomenological model in the solution system containing inorganic salt-inhibitor of salt formation the process of crystal growth inhabitation with regard to speed kinetics of two-dimensional germs formation was investigated. The case of inhibitor particle diffusion across the surface and with their subsequent adsorption on the sides of growing crystal was observed. The main parameters of this process which are critical radius of two-dimensional germ, relative saturation of the solution and level rate of surface coating were researched. The process regularities of crystal structural unit integration into the growth step, rate of salt crystallization dependence on relative saturation of the solution as well as critical inhibitor concentration dependence on temperature were defined.
