Waste Stabilization Ponds (WSP)
Waste Stabilization Ponds (WSPs) are large, man-made water bodies. The ponds can be used individually, or linked in a series for improved treatment.…
Anaerobic Filter
An anaerobic filter is a fixed-bed biological reactor with one or more filtration chambers in series. As wastewater flows through the filter,…
Anaerobic Baffled Reactor (ABR)
An anaerobic baffled reactor (ABR) is an improved [8217-septic tank] with a series of baffles under which the wastewater is forced to flow. The…
Anaerobic Digestion (Large-Scale)

Settler
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…
Unplanted Drying Beds
An unplanted drying bed is a simple, permeable bed that, when loaded with sludge, collects percolated leachate and allows the sludge to dry by…

A horizontal subsurface flow constructed wetlandis a large gravel and sand-filled basin that is planted with wetland vegetation. As wastewater flows…
Vertical Flow Constructed Wetland
A vertical flow constructed wetland is a planted filter bed that is drained at the bottom. Wastewater is poured or dosed onto the surface from above…
Pre-Treatment Technologies
Pre-treatment is the preliminary removal of wastewater or sludge constituents, such as oil, grease, and various solids (e.g., sand, fibres and trash…
Disinfection and Tertiary Filtration
Depending on the end-use of the effluent or national standards for discharge in water bodies, a post-treatment step may be required to remove…
