Results of the test operation of FOPS® filter for treatment of stormwater runoff from residential areas in St. Petersburg
Summary
In the process of designing facilities for the treatment of surface runoff from residential areas certain difficulties arise with determining the composition and actual concentrations of pollutants required for the calculations. The task of the work was testing the operation on-site of a filter cartridge for the purification of polluted surface runoff flowing into the storm sewer from the residential area during the spring-summer period. The results of the study of the composition of surface runoff from the residential area and possible treatment with the use of a filter cartridge (FOPS®-MU) are presented. It is shown that highways contribute much to the pollution of the surface runoff from the residential areas. The main pollutants are suspended solids, oil products, iron and manganese. It is stated that the use of FOPS® - MU filter provides for the high efficiency of the surface runoff treatment during the entire period (April – September) without any losses of the nominal capacity.

Test operation of a two-stage plant based on FOPS® filters
for the enhanced treatment of surface runoff
Summary
Moto transport has been the main source of pollution of surface runoff in large cities; therefore, runoff from roads and car parking spaces must be subjected to enhanced treatment including several stages. As part of solving this problem, works were carried out to estimate the operation of a two-stage plant (based on sequentially operating FOPS®-S and FOPS®-MU filters) in the process of surface runoff treatment from the car parking spaces during various seasonal changes. As a result of test experiments, it was found that for 21 months the plant provided for 98–99% efficiency of removing suspended solids and 94–97% efficiency of removing oil products from the surface runoff. After three years operation including winter periods with below-zero temperatures to less than –20°C, the plant provided for the required treatment level according to the monitored parameters. Occasionally, the FOPS®-S filter was cleaned – removing suspended solids and oil products.

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).

Test operation of a FOPS®-S filter separator in the process
of surface runoff purification from the car parking area
Summary
Surface runoff from large metropolitan areas is heavily polluted. Car parking areas are of overriding concern in pollution since the surface runoff generated on them contains high concentrations of oil products and suspended solids. The aim of the project was multi-season test operation of a FOPS®-S filter-separator for the purification of the surface runoff disposed into the sewer system from the parking area. In the course of observations, it was found that over 21 months of testing, the FOPS®-S filter provided for removing
82–99% suspended solids and 55–76% of oil products from heavily contaminated surface runoff (at their maximum concentration in the surface runoff 3000 and 10.5 mg/dm3, respectively). No decrease in the treatment efficiency was observed for 21 months, including the periods of negative temperatures (two seasons). During the tests the hydraulic discharge of the trapped pollutants from the FOPS®-S filter was carried out twice: suspended solids (~ 130 kg) and oil products (~ 2.1 dm3).
10,5 мг/дм3 соответственно). Снижения эффективности очистки в течение 21 месяца не наблюдалось, в том числе в периоды отрицательных температур (два сезона). За время испытаний из фильтра ФОПС®-С дважды производилась гидровыгрузка задержанных загрязнений: взвешенных веществ (~ 130 кг) и нефтепродуктов (~ 2,1 дм3).

Ecological Rehabilitation of the Moscow Municipal Wastewater Disposal System
Summary
The suggestions about modernization of the disposal and treatment system of surface runoff from the territory of Moscow with due regard for environmental requirements set for water objects-water receivers have been developed by specialists of MosvodokanalNIIproekt on the basis of investigations of many years. The prognosis of possible reduction in pollution level of the city’s water objects as a result of execution of complex of measures aimed at the reconstruction of the wastewater disposal system and enhancement of the level of improvement of the city’s territories has been made on the basis of the analysis of change of pollutants concentration in the surface runoff in the course of its movement along the different parts of the wastewater disposal system. The suggestions take into account interconnection and interaction of all city’s water-management systems and can be used for search of optimal solutions concerning organization of surface runoff disposal and treatment for certain water collecting basins as well as in the course of actualization of the General scheme of disposal and treatment of surface runoff from the territory of Moscow together with the Program of rehabilitation of the city’s water objects.
