Sand filters

Stratified sand filter being used for on-site wastewater treatmentStratified sand filters have been studied as both secondary and tertiary treatment processes for on-site effluent. The effectiveness of different types of media has been analysed both in the laboratory and in real on-site conditions, including the use of recycled glass as an alternative media. Another area of research has been to design the optimum distribution manifold for the pumped discharge of effluent onto the top of the filters, thereby improving the overall treatment efficiency.
