Maintaining optimal pH is important for the removal of phosphorus from water. Phosphorus is most effectively removed at the neutral pH range, when the insoluble aluminum hydroxide is present. This hydroxide functions as a Lewis acid, [5] creating a flocculation environment similar to conventional wastewater treatment.
Enhanced biological phosphorus removal (EBPR) is a sewage treatment configuration applied to activated sludge systems for the removal of phosphate. [ 1 ] The common element in EBPR implementations is the presence of an anaerobic tank ( nitrate and oxygen are absent) prior to the aeration tank.
Glyphosate (IUPAC name: N-(phosphonomethyl)glycine) is a broad-spectrum systemic herbicide and crop desiccant.It is an organophosphorus compound, specifically a phosphonate, which acts by inhibiting the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSP).
Glyphosate, part of the herbicide "Roundup", is a phosphonate. 2-aminoethylphosphonic acid: the first identified natural phosphonate. Phosphonates are one of the three sources of phosphate intake in biological cells. [citation needed] The other two are inorganic phosphate and organophosphates.
In 1977 the United States Environmental Protection Agency published a position paper advocating for a phosphate ban in detergents.. States including Maine, Florida, and Indiana in the United States began restricting or banning the use of phosphates in laundry detergent in the early 1970s, culminating in a nationwide voluntary ban in 1994.

Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. [1] They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment.
