Matrix-filter system for algae and phosphorus removal

Abstract

This paper summarizes the results of extensive laboratory experiments conducted for the determination of the effectiveness of a matrix-fill filter in removing algae and phosphorus during tertiary treatment. Filtration with this system has resulted in effluent of the required quality, low phosphorus and algae effluent and turbidity, with long filter runs in all modes of treatment and without the need for an excessive head of water. The system is economically viable, easy to operate, and suited more to rural areas for small and medium sized communities.
