Phosphorus removal in a waste-stabilization pond containing limestone rock filters

Microbial Phosphorus Removal in Waste Stabilisation Pond Wastewater Treatment Systems

Waste Stabilisation Ponds (WSPs) are characterised by low phosphorus (P) removal capacity. Heterotrophic bacteria are principal microbial agents in WSPs in addition to algae. As treatment proceeds in WSPs, algal growth increases and pH rises, this has lead to believe that P removal is mainly through sedimentation as organic P algal biomass and precipitation as inorganic P. In activated sludge t...

Waste Stabilization Ponds for Waste Water Treatment, Anaerobic Pond

Waste stabilization ponds (WSP) have been used world-wide over the last 50 years for municipal and industrial wastewater. The waste water treatment system has been accepted and used to change the physical, chemical, or biological character of the waste. This article presents the characteristics, parameters, and examples of the waste stabilization ponds all over the world. This work was based on...

The removal of thermo-tolerant coliform bacteria by immobilized waste stabilization pond algae.

This study investigated the potential of laboratory- scale columns of immobilized micro-algae to disinfect effluents using thermo-tolerant coliforms (TTC) as a model system. Cells of a Chlorella species isolated from a waste stabilization pond complex in Northeast Brazil were immobilized in calcium alginate, packed into glass columns and incubated in contact with TTC suspensions for up to 24 ho...

Reusing industrial by - products to enhance phosphorus removal in 1 waste stabilization ponds : laboratory approach

Modeling Wind Effect on Waste Stabilization Pond Performance

Wind has an important effect on the behavior of ponds as it induces vertical mixing of the pond contents. Good mixing ensures a more uniform distribution and higher dispersion number within the pond and hence a better degree of waste stabilization. This study developed a mathematical model for the prediction of Coliform bacteria ( ce /co) on waste stabilization pond performance. The model was d...
