Analysis and specifications of filtration of surface runoff from railway track ballast section

Summary

Rail transport facilities are fixed structures that produce continuous impact on the environment. The main facilities – pollution sources among rail transport facilities are railway stations. In most cases polluted runoff from railway station tracks generated mainly as a result of atmospheric precipitations leaks through the surface relief, infiltrates into the subsurface, penetrates deeply and drains with underground water into the nearest water bodies. The processes of surface runoff filtration through multilayer porous media that are taking place in the ballast section of the railway track have been analyzed and specified. Possible hypotheses of liquid behavior and properties in multilayer porous media, in particular of the liquid on the surface of ballast section of the railway track accumulated as a result of atmospheric precipitations; steady and unsteady liquid seepage into the railway ballast depth; dissipation of oil product spills on railway tracks are presented.

Protection of the Imeretinskaia Lowland from surface runoff flooding

Summary

Short information on the engineering-construction solutions of removing surface runoff from a development area on the Imeretinskaia Lowland territory of the Krasnodar Area is presented. Its surface is slightly elevated above the sea level (from 0.7 to 4 m); therefore, pressure removal of 100% storm runoff which at times becomes a disaster (during heavy rains) and causes significant damage to the territory is required. Removing surface runoff from residential areas of the Olympic park also requires advanced treatment. Taking into account the construction conditions the entire territory has been divided into five drainage areas to reduce the depth of the collection network and engineering structures. In each area a complex including a pumping station, an accumulating tank and advanced treatment facilities has been designed and built. The surface area of the drainage sites significantly differs from each other (30–440 ha). Following the extended survey and substantiation of the pumping equipment choice angular flow pumps with capacities 5 and 12.1 m3/h and 12.5 m head were selected. Taking into account the partial removal of pollutants in the accumulating tank two-stage filtration was used for advanced surface runoff treatment. Wastewater is treated with «Aqua-Aurat™18») coagulant and processed in the filters of the first stage with quartz sand media. To provide for the complete removal of residual dissolved oil products wastewater is supplied to the rapid gravity sorption filters of the second stage with MIU-S2 activated carbon media. The accumulating tank is cleaned from sludge regularly 2–3 times a year using a bucket loader. Sludge generated in the process of chemical wastewater treatment is dewatered in a belt filterpress. Dewatered sludge is disposed to the solid waste landfill.

The use of membranes for surface runoff and recycling car wash water treatment

Summary

The results of investigating the technology of surface runoff and recycling car wash water treatment with the use of reverse osmosis systems equipped with specially designed membrane units with «open» channel that provide for processing water with high concentration of suspended matter are presented. For processing raw wastewater in the membrane unit two concentrating stages are used: at the first stage – reverse osmosis membranes that ensure high quality treatment, and at the second stage – nanofiltration membranes that ensure concentrating solutions with high salt content with the minimum power consumption. The specific feature of the technology is in the utilization of the reverse osmosis concentrate that is removed from the system together with wet sludge. The results of the laboratory studies of storm water membrane treatment with the use of special roll elements with «open» channel and new BLF membranes are presented. It is stated that increasing permeate output to 0.9 results in 2.5–3-fold decrease of the equipment capacity. Car wash water undergoes the same treatment. The pilot tests show that increasing salt concentration in recycling water higher than 17 000 mg/l is impractical. The relationships of the increase of pollutant concentration in permeate and membrane capacity depending on the increase of the salt content in water under treatment and the ratio of volume concentrating in a reverse osmosis unit are presented. The parameters of membrane units operating with wastewater of this type with efficient removal of oil products, detergents and other pollutants are determined. Possible utilization of concentrate is shown.

Mathematical modeling of water course pollution with surface runoff from railroad tracks

Summary

The directions of railroad tracks located in the Ryazan, Tambov, Penza, Ulyanovsk, Orenburg Regions, Mordovia, Tatarstan, and Bashkiria are considered. The parameters and characteristics of the railroad tracks of the Kuibyshev railway on the section of the Samara Region: the length of the section, number of crossings with water bodies, average crossing value per 1 km, crossed water bo­dies, the length of the water flow along the railroad tracks, specific combined index of river water pollution are presented. The average value of railway crossings with water bodies in the Samara Region is 0.549/km, i. e. approximately one crossing per every 500 m. Correspondingly in every 500 m surface runoff from the road track and adjacent area enters the water body from four sides. A method of mathe­matical modeling of surface runoff from railroad bed entering water bodies is proposed provided water bodies are located parallel to transport trunk railways in the presence and introduction of previously ignored additional pollution into water bodies. The requirement for surface runoff from railroad and water body crossings treatment is substantiated.

The experience of year-round operation of FOPS® filter in the purification of surface runoff from technologically disturbed resident areas

Summary

At present residential areas in big cities in particular, have been exposed to technogenic pollution related to heavy traffic, development of managed territories including areas close to big shopping and leisure centers and other crowded places. In order to improve the quali­ty of life for the citizens and reduce the negative impact on the environment special attention shall be paid to the collection, removal and treatment of surface runoff from such territories. The purpose of testing FOPS®-MU filter during four seasons (spring – summer – autumn –winter – spring) was the assessment of the efficiency and practicability of operating this equipment for surface runoff treatment. In the process of observations it was stated that the main source of the pollution of surface runoff from resident areas (suspended solids, oil products, iron, manganese) was automobile transport. Peak concentrations of some pollutants reached 150–400 maximum permissible concentrations set for the effluent discharged into the municipal sewer. Year-round continuous operation (for 13 months) of FOPS®-MU filter showed high treatment efficiency in relation to different pollutants during the entire testing period without any loss of the operating capacity including after the negative temperature period. The high performance characteristics of FOPS®-MU filter were also promoted by using FOPS®-K filter-basket for collecting waste.

The experience of using «Recommendations on designing the systems of collection, disposal and treatment of surface runoff from territories allotted for settlement and industrial sites, and on determining the conditions of its discharge into water bodies»

Summary

The experience of using «Recommendations on designing the systems of collection, disposal and treatment of surface runoff from territories allotted for settlement and industrial sites, and on determining the conditions of its discharge into water bodies» developed at NII VODGEO Federal State Unitary Enterprise in substitution of previous «Temporary re­commendations on designing facilities for processing surface runoff from industrial sites and determining the conditions of its discharge into water bodies» is considered. The high demand for the developed document by the experts in the process of designing and approving project documents on construction and upgrade of engineering structures of storm sewers is noted. The use of advanced methods of calculating surface runoff amount and flow rate provides for minimizing the capacity of the treatment facilities at guaranteed meeting the requirements of the regulations on the conditions of disposal and quality of surface runoff effluents. The list of priority water quality parameters to be guided when choosing a treatment process flow scheme is presented. The basic technical solutions of surface runoff collection, disposal and treatment are formulated. The principle of wastewater flow separation and accumulation is suggested together with the technologies of its engineering implementation that provide for reasonably reducing the investments for the construction of treatment facilities under the existing environmental legislation and design regulatory framework. The need for updating the section on the recommendations on determining the conditions of surface runoff disposal into water bodies that was developed following the amendments to the RF Water Code and enactment of the new regulatory and procedural documents related to developing the regulations on permissible impact on water bodies and permissible discharges for water uses is noted.

The experience of using peat filtration for surface runoff treatment

Summary

The 20-year experience of using peat filtration technology for surface runoff treatment has been described. The advantages of the technology are given; the simplicity of operation in a large range of surface wastewater amount is noted. The choice of treatment techno­logy and filtering materials is a rather complicated task, since it requires achieving effective purification at minimum cost and without using extra electricity. The natural origin of peat, its availability, good filtering properties, ease of disposal and low cost determine the prefe­rence of its use in surface runoff treatment technologies. In the period 1994–2018 a group of companies developed a system for passive mechanical treatment of surface runoff using peat filtering materials. At the facilities of the North-West Federal District of the Russian Federation more than 900 systems for the purification of surface runoff of various amounts were introduced including more than 300 on the R-21 Kola highway and large Pulkovo-3 facilities with a capacity of 700 m3/h in St. Petersburg. The absence of the need to use electricity even in minimal amounts has provided for the efficiency of such technologies. The widespread introduction of peat filtration can be attributed to the best available technologies.

Removing oil products and detergents from surface runoff with the use of reverse osmosis systems

Summary

The studies of developing advanced technologies of surface runoff treatment from oil products and detergents are presented. The technologies are based on the process of reverse osmosis with the use of membrane units of a new type with an «open channel». Eliminating the causes of deposit formation can provide for ten-fold increase of the incoming water concentration in the units. The amount of concentrate (aqueous solution containing concentrated pollutants) is reduced to less than 1% of the initial water amount. With such small amount the concentrate is removed together with sludge. The estimations of the economic benefit of the rational utilization of surface runoff for technical purposes are presented.

Rainfall parameters for the calculation of the capacity  of surface runoff treatment facilities

Summary

The summarized data on the maximum depth of the rainfall that is completely removed to the treatment facilities (like the runoff from the group 1 residential and industrial areas in big cities of the Russian Federation) is presented. The analysis of the revealed regularities was carried out. The calculated values of the rainfall depth obtained in the course of observations at 87 meteorological stations on the territory of the Russian Federation are needed for calculating the capacity of the surface runoff treatment facilities and can be used in the process of making designs for settlements where the data of the meteorological stations is representative. The rainfall depth that provides for removing at least 70 % of the annual rainfall to the treatment facilities in most cases corresponds to the upper limit of the recommended range of 5–10 mm.

Surface runoff of Samara: effect of the seasonal factors

Summary

Surface runoff is still one of the main sources of pollutants discharged into water bodies. By the example of the storm sewer system of Samara urban district the detailed qualitative and quantitative characteristics of the discharged wastewater are considered. The storm sewer of Samara receives surface runoff and drainage water from the urban territory and territory of industrial enterprises, clean surface runoff, drainage flow from heat distribution networks and process effluent generated in the process of the network maintenance. The data is presented on the assessment of the seasonal variation of the effluent quality. A representative set of indicators for monitoring purposes and diagnostics of the state of the wastewater disposal system is presented. The representative diagnostic set includes the following indicators: рН, BODfull, suspended solids, dry residue, ammonium, nitrates, nitrites, copper, aluminium, oil products. The results of the studies of interaction between the raw water quality coming to the pumping filtration station of Samara and characteristics of the surface runoff discharged upstream the same water body are cited. It is shown that the water source turbidity and color are related to certain qualitative parameters of the surface runoff. The level of this interaction is estimated; calculation dependencies are proposed. The need for the further implementation of the municipal program of the storm sewer system of Samara urban district is substantiated.

Designing the project of surface runoff treatment facilities in Samara

Summary

The results of developing design and engineering documentation of the main intercepting sewer and treatment facilities for surface runoff from the drainage area of the Volga downhill of Samara are presented. The runoff produces a negative impact on the river intake of the two main municipal pumping-filtration stations. Designing and constructing these projects are implemented within the frames of the high-priority activities envisaged by the Master Plan of Samara approved in 2008. The route of the main rainwater sewer approved in the project provides for the possible connection of eleven outfalls discharge untreated surface runoff into gulleys of the Volga downhill. The process of surface runoff treatment envisages four stage water treatment with flow rate and pollutant concentration equalization in accumulating tanks: the first stage – mechanical treatment (screening, sedimentation in grit chambers and accumulating tanks); the second stage – physical and chemical treatment (coagulation of pollutants, sedimentation in laminar settling tanks); the third stage – enhanced treatment (filtration in contact clarifiers, two-stage filtration in sorption filters with MIU-S media); the fourth stage – UV water disinfection.

Explanation of separate provisions of the Recommendations for designing the systems of the surface runoff from residential areas and industrial sites collection, disposal and treatment

Summary

Guidelines and regulations for designing the systems of surface runoff (rainfall, snow-melt, street washwater) from residential areas and industrial sites disposal and treatment are presented as well as the comments to the provisions of Code of Practice 32.13330.2012 «Sewerage. Public Utilities» and «Recommendations for designing the systems of collection, removal and treatment of the surface runoff from residential areas, industrial sites; and determining the conditions for its discharge into the water bodies» («NII VODGEO» OJSC). The above-noted documents permit disposal for treatment of the most polluted part of the surface runoff in the amount of more than 70% of the annual runoff from residential areas and industrial sites similar to them in pollution level, and the total runoff from industrial sites with the territories that could be polluted with specific substances with toxic properties or significant concentrations of organics. The common practice of designing engineering structures of separate and combined sewers that allow short-term discharges of part of runoff into water bodies through separating chambers (storm-overflow sewers) at heavy (storm) rains of rare occurrence is considered. The cases are considered related to the refusal of the territorial directorates of State expert assessment department and Russian Federal Fisheries Agency to allow activities in relation to the capital construction projects under design pursuant to article 60 of the RF Water Code that prohibits discharging wastewater without sanitary treatment and decontamination into water bodies.

Calculating the charge for the negative environmental impact produced by rail transport facilities

Summary

Basing on the results of chemical analyses and regulatory requirements to the environmental protection activities the analysis of the impact of surface runoff from rail transport facilities on the environment was carried out. Different charges imposed on natural resource users for water body pollution are described. The efficiency aspects of investing in the development of wastewater treatment and polishing are addressed. The costs associated with treatment will depend on the wastewater flow that determines the capacity of the treatment facilities, as well as on the required concentration of pollutants in the effluent that determines the required level of treatment, i.e. the number of stages and treatment technology. Under the conditions of the capital investment tightness it would be reasonable to determine the efficient investment trends in each particular case. The maximum permissible discharge of any pollutant will depend on its permissible concentration in wastewater that is assumed as a basis for designing treatment facilities. The evaluation of the investment efficiency is carried out by specifying the discharge of pollutants into water bodies that will determinate the cumulative expenses. The minimum cumulative expenses including the annual construction and operation expenditures as well as the effluent charge could be determined for every pollutant. To substantiate the expediency of surface runoff collection, removal and treatment the calculation of charging for nonpoint discharge of the surface runoff from rail tracks was carried out.

Test operation of FOPS® filter with natural zeolite
for infiltrate polluted surface runoff treatment

Summary

Infiltration effluent often causes heavy pollution of surface runoff with heavy metal ions. The purpose of the present work was testing the operation in-situ of a cartridge filter with natural zeolite for surface runoff treatment polluted with heavy metals from infiltrate. The results of studying the level of pollution of storm runoff from industrial site are presented. As part of the study the following challenges were addressed: study of formation of surface runoff heavily polluted with infiltrate at the site and treatment options; implementation of sorption-filtration technology in a real project with the use of filters for surface runoff treatment (FOPS®) installed in sewer manholes; evaluation of the possible removal of heavy metal ions from real runoff with natural zeolite-clinoptololite. Possible purification of the studied runoff with the use of FOPS®-TS filter with natural zeolite was substantiated. It was shown that ultra high concentrations of aluminium, zinc and copper are formed in infiltrate entering the drainage system on site. Using FOPS®-TS filter provided for the high efficiency of aluminium, zinc, copper and iron removal during the test period (April – October).
