Cross-flow microfiltration is one of the most promising solid-liquid separation processes, which can provide thorough separation with high rate.
A suspension to be filtrated is forced tangentially over a membrane surface to back-transport the filtered colloidal particles from it.
By the simulation with the rheological equation of activated sludge and the equation of the filtration with submerged membrane, suitable membrane module design was decided as the clearance in the flat-type membrane module having elements inside of 8 mm.
The Pilot-plant had been operated successfully for 6 months.
