PROCESS AND APPARATUS FOR TREATING LIQUID WASTE MATERIAL

摘要

A process for treating liquid waste material, comprises first adding a chemical flocculent to the liquid waste material followed by mixing to promote flocculation. The floc material is subsequently separated to produce a bulk clarified liquid, with the floc material being subjected to a solids separation to extract further bulk clarified liquid. The collected bulk clarified liquid is then recycled back into at least one of the steps of adding a chemical flocculent and solids separation of the floc material. The process is suitab le for use with a wide variety of liquid waste materials ranging from agricultural and human waste to industrial waste. An apparatus for treating liquid waste material is also provided.
