Secondary treatment definition

Secondary treatment means a combination of unit processes that will consistently remove 85% or more of the organic and suspended material in domestic wastewater and produce an effluent of sufficient quality to satisfy the following requirements; monthly average effluent BOD5 and TSS concentrations of 30 mg/L; daily maximum effluent BOD5 and TSS concentrations of 45 mg/L.

Secondary treatment means the stage in sewage treatment in which a bacterial process (or an equivalent process) consumes the organic parts of wastes, usually by trickling filters or an activated sludge process.

Secondary treatment means treatment of urban waste water by a process generally involving biological treatment with a secondary settlement or other process in which the requirements established in Table 1 in Schedule 3 are respected;
