Waste-Water Treatment Apparatus

摘要

The design and operation of equipment for lowering the COD and BOD of domestic and industrial waste water are described. The invention is intended for the treatment of waste water in a very short time at low waste water in a very short time at low cost. It incorporates the harmful organic substances, which represent the main part of the COD and BOD activity, into spinel or inverse-spinel structures by means of iron ions, and then removes the product magnetically.
