Primary Treatment
**[[:File:Septictanksizingtool2.xlsx|Septic Tank Sizing Tool (.xlsx)]]
*[[Practitioner's Tool / Technology and Operation / Vermicomposting digester|Vermicomposting digesters]]: This system provides aerobic primary treatment by providing an enclosed environment in which worms transform solid effluent into humus. Liquid is separated from solids by draining through a filtration medium that retains solids. Aerobic digestion is faster and generates less smell than septic tanks.*[[Practitioner's Tool / Anaerobic_Baffled_Reactor_(ABR) 2|Anaerobic Baffled Reactors]]: An anaerobic baffled reactor (ABR) is a tank with several compartments that is designed to reduce the organic and suspended matter in the wastewater by about 70%. Raw wastewater enters the ABR tank through the inlet structure, which directs the flow to the bottom of the first compartment. Due to the nature of wastewater under anaerobic conditions, a granulated sludge blanket is formed. As the wastewater flows up through the sludge granules, the solids are trapped in the sludge blanket where anaerobic bacteria consume the organics as food.

*[[Practitioner's Tool / Technology and Operation / Sewage_Lagoons|Sewage Lagoons]]: Sewage lagoons are lined ponds or basins that treat wastewater through&nbsp;the physical action of settling and the biological action of microbial digestion. Also known as waste stabilization ponds, sewage lagoons are popular because they are relatively inexpensive and easy to design, install and maintain and can produce a good quality effluent. They do, however, require large land areas.

*[[Practitioner's Tool / Technology and Operation / Biogas_Systems|Biogas Systems]], [[Biogas Reactor]], [[Biogas Combustion]]: A biogas reactor or anaerobic digester is an anaerobic treatment technology that produces (a) a digested slurry (digestate) that can be used as a fertilizer and (b) biogas that can be used for energy. Biogas is a mix of methane, carbon dioxide and other trace gases which can be converted to heat, electricity or light.**[[Practitioner's Tool / Chinese_Dome_Digester|Chinese Dome Digester]]
*Interceptor Tanks: A settler is a primary treatment technology for wastewater; it is designed to remove suspended solids by sedimentation. It may also be referred to as a sedimentation or settling basin/tank, or clarifier. The low flow velocity in a settler allows settleable particles to sink to the bottom, while constituents lighter than water float to the surface.
