The wastewater comes in the form of grey and black water and their treatment can be carried out separately or by using the same equipment to process both grey and black wastewater.
What are the types of wastewater treatment technologies?
Wastewater treatment technologies or advanced waste water treatment methods can be broadly classified into three sub divisions and are as follows: 1. Physical treatment method:It involves removal of pollutants/contaminants by physical forces. 2. Chemical treatment method:Removal of impurities or toxic wastes through chemical reactions.
