Abstract

Waste water passes through conventional purifiers and is then treated first with iron III chloride, to precipitate out dissolved phosphates, followed by a flocculating agent to agglomerate the precipitate. The water is then filtered through a tangled fibre fleece arranged on a rotary filter drum.
