Experience in the treatment of surface runoff of complex composition using multi-stage units based on FOPS^® filters

Summary

Many years of experience in keeping track of the composition of surface runoff from various residential areas are described. An estimation was made of the actual contamination of surface runoff generated in the territories of tangible objects. The results of full-scale tests and practical operation of multi-stage units on the basis of FOPS^® filters at various districts of St. Petersburg with heavily polluted surface runoff of a complex composition are presented. The actual composition of surface runoff from technogenic residential areas experiencing high traffic load differs significantly from the recommendations of current regulatory and technical documents. The sorption-filtration technology implemented with FOPS^® filters has been a most technically developed technology that provides for designing multi-stage units for the integrated treatment of surface runoff.
