✦ Synopsis

This paper describes a novel, biological wastewater treatment process which uses a bioreactor of immobilised biomass coupled with a crossflow microfilter. Plant trials on domestic wastewater have demonstrated that an effluent BOD, of c Sppm (98% removal efficiency) and suspended solids of Oppm can be achieved. The bioreactor residence time is an order of magnitude less than for conventional activated sludge and the requirement for liquid backwash is only a small percentage of total flow. The integrated system is compact and energy efficient. Potential applications of this new system are discussed.

In tests on activated sludge wastewater treatment using hollow fiber microfiltration membranes, during continuous filtration 2 stages of filtration pressure were found -a stationary phase where fouling progresses and a non-stationary stage with interfiber clogging.

Waste water from wheat starch production was treated by a membrane combined two phase methane fermentation system with 20kg/m3d of COD loading. The following satisfactory results were obtained: BOD and SS concentration in the system effluent was under 50 mg/l and 90 mg/l respectively. More than 99%
