Abstract

 The feasibility of two accumulation-systems (AC) (or anaerobic digestion and storage of concentrated black-water with (ACL) or without (AC2) urine + kitchen organic-wastes were investigated the wastewater was collected by two vacuum toilet transport system. The influent-total chemical oxygen demand (COD) of the AC2 system (54000 Mg/L) was more concentrated by than thus of the ACT system. The AC systems demonstrated stable performance. There was no inhibition effect of ammonium (NH4) and volatile fatty acids (VFA) concentration decreased in time, COD, removal of 58 % was achieved in both systems, after 105 days ill 20oC. Moreover, is the supernatant in the ACL system is only withdrawn and the settled sludge styles for the next runs, only 20% of the influent total-COD will be in the supernatant. In the AC2 system, 74 % of influent orthophosphate was removed by precipitation. A mathematical model based on anaerobic digestion model no. 1 showed that the design filling-period for both AC systems should be higher than 100 days at 20°C for obtaining >50% conversion of the wastewater to methane.
