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.

Effect of dispersion characteristics of suspended solids
on the parameters of surface runoff treatment

Summary

Quantitative and dispersion characteristics of insoluble pollutants in rainfall and snow-melt water and its effect on the parameters of removing pollutants from water by sedimentation, chemical free and chemical filtration are considered. It is shown that the concentration of suspended solids in surface runoff multiply exceeds the concentration of oil products whereupon these pollutants are present in the form of two-component particles. In the particles oil products or inorganic admixtures can be adsorbed components, and during sedimentation of surface runoff suspended solids and oil products are being removed synchronically. The concentration and kinetic consistency of suspended solids from residential areas are lower than those from highways; which reduces the sedimentation time in the storage settling tank and concentration of pollutants in settled water. During 1–3 days of settling tank empting monotonic reduction of suspended solids concentration in settled water before filtration occurs. Fluctuation range depends on the sedimentation time in the settling tank, initial suspended solids concentration and tank empting time. The use of coagulants before filtration of settled surface runoff from highways provides for improving the treatment efficiency and obtaining sustained quality of filtered water.

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.

Study of oil products and heavy metals removal from surface runoff in phytofilters

Summary

Internationally the use of bioengineered facilities including phytofilters in the treatment of surface runoff from urban lands is gaining ground. The use of phytofilters in moderate climate belts has some restrictions related to the decline in treatment efficiency during the periods of near-zero temperatures because of the retardation of biochemical processes in plants and soil microorganisms. A technical solution of the described problem is proposed that consists in adding materials with sorption and ion-exchange properties (peat and zeolite) into the filter media. The efficiency of removing oil products and heavy metals (lead, copper, aluminium, iron) from the simulated solution of surface runoff in a pilot laboratory phytofiltration plant with the use of higher plants: common reed grass (Phragmites commnis), mace reed (Tpha latiflia) and Iris pseudacorus was studied. The efficiency of removing oil products was 95.5–98.9%, and that of heavy metals – 66–99.3%. It was stated that during the vegetation period partial phytoregeneration of the filtration media from the trapped oil products and heavy metals occurs under the effect of higher plants and rhizospheric microflora. By experiment it was determined that the efficiency of phytoregeneration from oil products decreases in series: common reed grass – Iris pseudacorus – mace reed; from heavy metals: Iris pseudacorus – common reed grass.

Purification of storm water from the territories of industrial enterprises

Summary

The state of surface runoff disposal systems in Russia has been considered. In many cities the systems of atmospheric precipitation removal are in an extremely unsatisfactory condition since they have hardly undergone any upgrade. During intensive precipitation and heavy snowmelt rain and melt water accumulate on the territory of industrial enterprises. At the same time the treatment of surface runoff is complicated by the increase in volumes of wastewater and the physical deterioration of treatment facilities. As a result surface runoff containing suspended solids, oil products and other pollutants enters water bodies without treatment producing a negative impact on the ecosystem of water bodies. The characteristic of the composition of surface runoff of industrial enterprises is given on the example of a coal preparation plant in the city of Novosibirsk. Methods of treatment are considered. In order to reduce the harmful effects of surface runoff on water bodies at the Novosibirsk State University of Architecture and Civil Engineering (Sibstrin) storm water treatment technology has been developed that provides for the effluent discharge into open water bodies or usage in recirculating water supply of enterprises.

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.
