The study of the influence of the contact filter with polystyrene filter loading on the concentration of residual aluminum during the purification of natural surface water
Abstract
Residual aluminium is one of the standard indicators of the quality of water treatment facilities. Due to a number of interrelated factors to keep its regulatory concentration in purified water is becoming increasingly difficult. Proposed solution simplifies this task. It is based on the reconstruction of existing facilities — flocculation chambers horizontal tanks in contact Filters — Prefilters. After the reconstruction of such structures can serve as the contact filters, coagulation in cramped conditions and prefilters for the detention of phytoplankton. Full-scale simulation of such a facility, using the use of filter media made of foamed polystyrene granules. The dependence of the concentration of residual aluminium on the filtration rate and the dirt holding capacity of such a combined structure were defined.
