The Application of Biofiltration with Polyurethane Foams for Domestic Sewage Treatment

Ewa Dacewicz


The study presents the results of an experimental method for purification of household sewage on biofilters filled with polyurethane waste in the form of trims of upholstery foam (PUF). We assesses removal effectiveness of organic compounds, ammonium nitrogen and total suspended solids from sewage pre-treated in a septic tank at hydraulic loading ranging from 31.8 to 229.2 mm-1. Five month performance outcomes identified the biofilter filled with 30 cm thick foam as the most effectively removing BOD5, CODCr, N-NH4+ and total suspended solids. Average reduction in pollutant levels for this filter reached 95%, 94%, 84% and 68%, respectively. PUR foam in the form of trims of upholstery foam filling the vertical flow filters ensured favorable conditions for development of heterotrophic and nitrifying bacteria without any need for additional aeration.
