Phosphorous removal from wastewater Controlling phosphorous discharged from municipal and industrial wastewater treatment plants is a key factor in preventing eutrophication of surface waters. Phosphorous is one of the major nutrients contributing in the increased eutrophication of lakes and natural waters.

Phosphorus Treatment and Removal Technologies wq-wwtp9-02, June 2006 Municipal Division Wastewater Program ... amount of phosphorous entering the wastewater treatment plant. Enhanced Biological Phosphorus Removal (EBPR)
Phosphorus removal is a bigger issue today than ever before. State laws limit the levels of phosphorus that can be discharged from wastewater into the environment. Generally, the enforcement of these laws also happens at the state level. Many U.S. states currently regulate, or will soon regulate, these phosphorus levels.
C. Biological Treatment 1. Assimilation Phosphorus removal from wastewater has long been achieved through biological assimilation – incorporation of the P as an essential element in biomass, particularly through growth of photosynthetic organisms (plants, algae, and some bacteria, such as cyanobacteria).
Phosphorus removal from wastewater can be achieved either through chemical removal, advanced biological treatment or a combination of both. The chemical remobal of phosphorus involves the addition of calcium, iron and aluminium salts to achieve phosphorus precipitation by various mechanisms which are discussed.
Phosphorus removal from wastewater can be achieved either through chemical removal, involving the addition of calcium (lime), iron (ferric chloride) and aluminium salts (aluminium polychloride), advanced biological treatment, involving heterotrophic bacteria, called polyphosphate accumulating organisms (PAO) or a combination of both.
Biological Nutrient Removal (BNR) is a process used for nitrogen and phosphorus removal from wastewater before it is discharged into surface or ground water. The rising concentration of harmful nutrient compounds – specifically nitrogen and phosphorus – in municipal wastewater treatment plant discharge causes cultural eutrophication (nutrient enrichment due to human activities) in surface waters.
Phosphorus removal from wastewater can be achieved either through chemical removal, advanced biological treatment or a combination of both. The chemical remobal of phosphorus involves the addition of calcium, iron and aluminium salts to achieve phosphorus precipitation by …

Phosphorus removal from wastewater effluents can be achieved in two fundamentally different ways: by physical-chemical precipitation and by enhanced biological removal (although both, in essence, entail the creation of particulate matter that can be separated from the water).
The removal of nitrogen and phosphorus from wastewater has become an emerging worldwide concern because these compounds cause eutrophication in natural water. Moreover, nitrate is a risk to human health, especially as a possible cause of infant methaemoglobinaemia [ 1 ].

biological treatment plants, many waterways have still suffered negative effects. In Sweden, for example, very stringent laws have been passed on the effluent quality of municipal wastewater with respect to phosphorus. To meet up with such laws, biological phosphorus removal methods and chemical treatment methods are being used.
Sewage treatment is the process of removing contaminants from municipal wastewater, containing mainly household sewage plus some industrial wastewater. Physical, chemical, and biological processes are used to remove contaminants and produce treated wastewater (or treated effluent ) that is safe enough for release to the environment.

Phosphorus is a nutrient that is essential to farming. Yet runoff of phosphorus into waterways can contribute to toxic algae blooms. It’s why environmental regulations require wastewater treatment operators to remove phosphorus from effluent. The existing Liverpool system removed phosphorus in an unrecoverable form.
