The application of biological filters (fixed film processes) for the removal of ammonia from brackish or salt wastewaters from fish farms is discussed. The biological removal of ammonia in fixed-film processes is explained and design examples for ammonia removal in either trickling filters or rotating biological contactors are discussed.

SKG Sangha (SKG S) is a non-profit organisation that supplies biogas plants to households in rural areas of South India. The ‘Deenbandu’ design plants are built on-site by local masons and labourers trained by SKGS, with very high quality standards. Plants produce biogas by digesting cow dung, replacing all the fuel wood used for cooking.
