An innovative process for treatment of municipal wastewater with superior charcteristics compared to traditional techologies

An innovative treatment process for municipal sewage, which results in low sludge production, low energy consumption, high COD removal and high energy and nutrients recovery, is described. The organic matter will primarly be removed through anaerobic degradation using high-flow reactors. For nitrogen removal, the anammox process and an innovative physico-chemical method, will be described.

These separation technologies have showed promising prospects for cost effective removal of ammonia. For phosphorus removal, biological process will be used. On-line volatile fatty acids (VFA) monitoring and control will ensure optimum utilization of VFA's for P removal and biogas production. Thermal hydrolysis for treatment of residual sludge will be used for further decreasing the amount of excess sludge.

Finally, socio-economic evaluation of the process relative to the traditional treatment concepts will be worked out.
