Experience of all-season use of FOPS® filter with natural zeolite for the treatment of surface runoff from technologically disturbed territories

Summary

The aspects of pollution of surface runoff from residential areas with heavy metals is considered, and the main sources of their inflow are described. The results of full-scale tests of FOPS®-Z filter (with natural zeolite media) are presented. The efficiency and level of heavy metals removal from surface runoff using the FOPS®- Z filter was estimated. Tests were carried out on a real residential area in St. Petersburg for seven seasons (2021–2022). The results of using FOPS®-K filter basket (installed upstream of FOPS®-Z filter) at the first stage of purification of surface runoff from the residential area are presented, as well as the results of a study of the fractional composition of wastes accumulated in the FOPS®-K filter basket for the entire period of testing.

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).
