| 1 | WSP |  |
Waste or Wastewater Stabilization Ponds (WSPs) are large, man-made water bodies in which blackwater, greywater or faecal sludge are treated by natural occurring processes and the influence of solar light, wind, microorganisms and algae. | High | No | Deep | Yes | 6000.0 | 30.0 | 40.0 | 30.0 | 20.0 | 45.0 | 2300000.0 | 200000.0 | Yes | 0.0 | ||
| 2 | ASP |  |
An activated sludge process refers to a multi-chamber reactor unit that makes use of highly concentrated microorganisms to degrade organics and remove nutrients from wastewater to produce a high-quality effluent. | Low | Yes | Shallow | Yes | 900.0 | 30.0 | 40.0 | 30.0 | 20.0 | 45.0 | 6800000.0 | 700000.0 | Yes | 0.0 | ||
| 3 | SBR |  |
Sequential Batch reactors are aerobic suspended-growth type processes. Large amounts of injected oxygen allow maintaining aerobic conditions and optimally mixing the active biomass with the wastewater to be treated. Activated sludge systems are highly efficient for organic matter and nutrient removal, though pathogen removal is low. | Low | Yes | Shallow | Yes | 450.0 | 30.0 | 40.0 | 30.0 | 20.0 | 45.0 | 7500000.0 | 600000.0 | No | |||
| 4 | MBR |  |
MBRs combine conventional biological treatment processes with membrane filtration to provide an advanced level of organic and suspended solids removal. The development of new polymeric membranes, cheaper and more resistant, together with less pressure requirements and higher permeate flow, has made the submerged membrane configuration in MBRs the most common, although it is also possible to use external membranes. | Low | Yes | Shallow | Yes | 450.0 | 30.0 | 40.0 | 30.0 | 20.0 | 90.0 | 30000000.0 | 900000.0 | No | 0.0 | ||
| 5 | ABR+CW |  |
An Anaerobic Baffled Reactor (ABR) is an improved septic tank because of the series of baffles over which the incoming wastewater is forced to flow. A constructed wetland (CW) is an artificial wetland created for the purpose of treating anthropogenic discharge such as municipal or industrial wastewater, stormwater runoff. | High | No | Deep | Yes | 2000.0 | 30.0 | 40.0 | 30.0 | 20.0 | 80.0 | 54671000.0 | 4000000.0 | No | 0.0 | ||
| 6 | CW |  |
A constructed wetland (CW) is an artificial wetland created for the purpose of treating anthropogenic discharge such as municipal or industrial wastewater, stormwater runoff. | High | No | Deep | Yes | 1000.0 | 30.0 | 40.0 | 30.0 | 20.0 | 20.0 | 4671000.0 | 600000.0 | yes | |||
| 7 | AF |  |
An anaerobic filter is a fixed-bed biological reactor with one or more filtration chambers in series. As wastewater flows through the filter, particles are trapped and organic matter is degraded by the active biomass that is attached to the surface of the filter material. Anaerobic filters are widely used as secondary treatment in household black- or greywater systems and improve the solid removal compared to septic tanks or anaerobic baffled reactors. Since anaerobic filters work by anaerobic digestion, they can be designed as anaerobic digesters to recover the produced biogas. | Low | No | Deep | Yes | 900.0 | 30.0 | 40.0 | 30.0 | 20.0 | 47.0 | 40000000.0 | 600000.0 | ||||
| 8 | ASP+reed bed |  |
An activated sludge process refers to a multi-chamber reactor unit that makes use of highly concentrated microorganisms to degrade organics and remove nutrients from wastewater to produce a high-quality effluent. Reed beds are aquatic plant based systems which allow bacteria, fungi and algae to digest the sewage and clean the water. | High | Yes | Deep | Yes | 2000.0 | 30.0 | 40.0 | 30.0 | 20.0 | 40.0 | 11026000.0 | 600000.0 | ||||
| 9 | UASB |  |
UASB maintains a high concentration of biomass through formation of highly settable microbial aggregates. Wastewater flows upwards through a blanket of flocculated biomass in a vertical reactor containing anaerobic bacteria, which break down carbonaceous organic matter. At the top of the reactor phase separation between gas-solid-liquid takes place. The process is suitable for both soluble wastes and those containing particulate matter. This technology is used as a primary treatment option and the effluent cannot be discharged directly without adequate post treatment. | Low | Yes | Shallow | Yes | 1000.0 | 30.0 | 40.0 | 30.0 | 20.0 | 45.0 | 6800000.0 | 600000.0 | ||||
| 10 | ABR |  |
An Anaerobic Baffled Reactor (ABR) is an improved septic tank because of the series of baffles over which the incoming wastewater is forced to flow. | Low | No | Deep | Yes | 1000.0 | 30.0 | 40.0 | 30.0 | 20.0 | 47.0 | 50000000.0 | 3000000.0 | ||||
