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 review of previous research, experiments and articles that discuss how the treatment is of great importance to humanity. Parasite removals were reduced 98% after using the treatment in several countries with 100 beds. There will be comparison and description of the WSPs in USA, Canada, Europe, and former Soviet Union. Experiments have shown how the treatment is effective due to the elimination of waste in water, improving water quality by a 95%. There are several types of waste stabilization ponds. They are: anaerobic, facultative, and maturation ponds. Approximately half of the solid waste left after primary treatment settles out in the oxidation ponds. The growth of algae in the oxidation ponds help water quality by increasing the oxygen and consuming Nitrogen and Phosphorous, two common nutrients that area found in waste water. Some pre-requisites may be used for efficiency of the process.
