Summary: Crossflow microfiltration, a membrane process, is becoming popular in water and wastewater treatment for reuse. Its main problem is clogging of membrane pores. This will be minimised (i) by introducing a new design of unsaturated flow static flocculator to reduce the solid load to the membranes and to modify the deposit characteristics; and (ii) by operating the membrane filtration below critical flux. This study will be carried out at a treatment plant site and will aid in the successful design and operation of membrane filtration plants, as well as providing the practical research training of two masters students.
