Advanced Integrated Wastewater Pond

Advanced integrated wastewater pond systems are improved conventional waste stabilisation pond (WSP) systems and are based on a series of four advanced ponds: An advanced facultative pond (AFP) containing a digester pit which functions much like an anaerobic pond integrated into the facultative pond; A high rate pond (HRP), covered by algae which provide oxygen to the water and take up organics and nutrients; An algal settling pond (ASP), where most of the algae produced in the HRP is removed; And finally an maturation pond (MP) for biological and solar disinfection.
