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;

Secondary treatment means a wastewater treatment process that goes beyond primary treatment to remove colloidal and dissolved organic matter and further remove suspended matter, usually by biological processes such as activated sludge and biological filtration treatment.

Secondary treatment means the treatment of sewage until the sewage has, calculated as a 30-day average:

Secondary treatment means treatment of urban wastewater by a process generally involving biological treatment with a secondary settlement or other process so that the treatment results in a minimum reduction of the initial load of 70 to 90 percent of BOD5;
