Urea, also called carbamide (because it is a diamide of carbonic acid ), is an organic compound with chemical formula CO (NH2)2. This amide has two amino groups (– NH2) joined by a carbonyl functional group (–C (=O)–). It is thus the simplest amide of carbamic acid .
The white bubbles are due to the diffused air aeration system. The activated sludgeprocess is a type of biological wastewater treatment process for treating sewage or industrial wastewaters using aeration and a biological floc composed of bacteria and protozoa. It is one of several biological wastewater treatment alternatives in Secondary ...
