Abstract

The present Swedish design values (DV) for urine, faeces, greywater and biodegradable solid waste were scrutinised and compared to the composition of these fractions in two blocks of flats, Gebers and Ekoporten. For evaluation of the greywater composition, two additional areas were included: the housing area Vibyasen and a calculation based upon the composition of the sewage sludge in Ryaverken sewage treatment plant in Gothenburg. The parameters scrutinised were dry mass, wet mass, BOD7, COD, N, P, K, Cu, Cr, Ni, Zn, Cd, Hg and Pb. Based on the results, new updated Swedish DV were proposed for these parameters in the fractions urine, faeces, greywater and biodegradable solid waste.
