Municipal wastewater treatment with pond technology : historical review and future outlook

, 2020
Facing an unprecedented population growth, it is difficult to overstress the assets for wastewater treatment of waste stabilization ponds (WSPs), i.e. high removal efficiency, simplicity, and low cost, which have been recognized by numerous scientists ...

Treatment of Slaughterhouse Wastewaters in Stabilization Ponds

Water Science and Technology, 1987
A sampling programme was devised to assess in terms of 5-day biochemical oxygen demand (BOD5), chemical oxygen demand (COD) and suspended solids (SS) removal the performance of one anaerobic, one facultative and two maturation ponds in series, for treating the wastewaters resulting from a slaughterhouse killing approximately 625 pigs/week.

Potential of Adding Constructed Wetland/Fishpond to Waste Stabilization Ponds to Improve Helminths Removal in Morogoro Municipality, Tanzania

Journal of Applied Sciences and Environmental Management, 2020
A study was conducted to establish the potential of constructed wetlands in Morogoro Urban District, Tanzania, to remove helminths from wastewater. The standard wastewater treatment regime was failing to effect reliable removal of helminth eggs and ...

Modelling the performance of anaerobic wastewater stabilization ponds

Water Science and Technology, 1995
The performance of the primary anaerobic pond at the Alsamra Wastewater Treatment Plant in Jordan was monitored over 48 months. Overall averages for the removal efficiencies of BOD5, COD and suspended solids were 53%, 53% and 74%, respectively. An improvement in removal efficiency with increase in pond water temperature was demonstrated. A model, which

Performance of municipal waste stabilization ponds in the Saharan desert (Morocco)

Journal of Water and Climate Change, 2023
The majority of cities in the Saharan territory of south Morocco utilize waste stabilization ponds (WSPs) for municipal wastewater treatment because of their relatively low capital, operational costs, and minimal complexity. New national effluent quality

Sludge Removal from Some Wastewater Stabilization Ponds

Water Science and Technology, 1990
The study of sludge accumulation in the first ponds of 12 treatment plants under oceanic climate showed a mean rate of accumulation of 2.8 cm per year corresponding to 0.12 m3 of sludge per inhabitant per year. Desludging was required about operation periods of 6 or 7 years.

Comparing the Efficiency of Stabilization Ponds and Subsurface Constructed Wetland in Domestic Sewage Treatment in City of Yazd [PDF]

آب و فاضلاب, 2016
Wastewater is one of the most important contributors to water pollution on the one hand, while it has the potential to serve as an alternative source of water if subjected to proper treatment, on the other.

Facultative Stabilization Pond: Measuring Biological Oxygen Demand using Mathematical Approaches

E3S Web of Conferences, 2018
Pollution is a man-made phenomenon. Some pollutants which discharged directly to the environment could create serious pollution problems. Untreated wastewater will cause contamination and even pollution on the water body.

Changes in Bacterial Communities During Treatment of Municipal Wastewater in Arctic Wastewater Stabilization Ponds

Frontiers in Water, 2021
Wastewater stabilization ponds (WSPs) are commonly used to treat municipal wastewater in the Canadian Arctic. Bacterial community structure and functionality remain mostly uncharacterized for arctic WSPs, yet are presumed important for treatment outcomes

Modelling Coliform Reduction in Wastewater Stabilization Ponds

Water Science and Technology, 1992
The paper addresses faecal coliform reduction in a large wastewater stabilization pond system. It was found that values of the faecal coliform reduction rate coefficient (Kb) increased with increasing water temperature (Tw), solar radiation (Rs) and pH and with decreasing total BOD5 (CBOD), soluble BOD5 (SBOD) and surface organic loading (BA,CBOD ...
