Simple sewage treatment processes for low and middle income countries

The webinar (July 27, 2021) provided an overview of simple sewage treatment processes that can be applied in warm-climate regions and also in low-and-middle-income countries. The processes covered are stabilization ponds, constructed wetlands, overland flow, UASB reactors, and post-treatment of anaerobic effluents. A comparison is made between their typical performances and characteristics, including their capacity to remove the major macro-pollutants of interest in domestic wastewater: organic matter, nitrogen, phosphorus, and pathogens.
