Some of the major process of secondary or biological treatment are as follows: (i) Activated Sludge Process (ii) Trickling Filters. The resulting “sludge” is then fed into a digester, in which further processing takes place. The two main types of sludgeproduced from the wastewater treatment process are primary and secondary sludge. 2. 1 Answer +1 vote . d (10 000 to 20 000 gpd/ft).

Typically, solids in the primary clarifier are inorganic whereas in a secondary clarifier, sludge is nearly 100 percent organic and thus can compact readily, making sludge far denser in a secondary unit than that of a primary system. At two activated sludge plants, primary sedimentation removed 4-42% protozoan (oo)cysts in comparison to 53-98% removal in activated sludge units (including secondary sedimentation) (Robertson et al., 2000b).
