The recovery of ,phosphorus, (P) from high-strength acidic ,waste, streams with high salinity and organic loads is challenging. Here, we addressed this challenge with a recently developed electrochemical approach and compared it with the chemical precipitation method via NaOH dosing. The electrochemical process recovers nearly 90% of P (∼820 mg/L) from cheese wastewater in 48 h at 300 mA with an ...

Excessive input of ,phosphorus, can change clear, oxygen-rich, good-tasting ,water, into cloudy, oxygen-poor, foul smelling, and possibly toxic ,water,. Therefore, control of the amount of phosphates entering surface waters from domestic and industrial ,waste, discharges, natural runoff, and erosion may be required to prevent eutrophication.

Phosphoric Acid is a colorless, odorless phosphorus-containing inorganic acid. Phosphoric acid is a sequestering agent which binds many divalent cations, including Fe++, Cu++, Ca++, and Mg++. Phosphoric acid is used in dentistry and orthodontics as an etching solution, to clean and roughen the surfaces of teeth where dental appliances or fillings will be placed.

Phosphorus, (P) is a chemical element with an atomic number of 15 and an atomic mass of 31. Due to its high reactivity, ,phosphorus does, not naturally exist as a free element. ,Phosphorus, generally occurs as phosphate in minerals. Phosphate is typically found in the Earth’s crust at a concentration of about 1 gram per kilogram.

The types of phosphorus in your wastewater will dictate not only how your phosphorus can be removed but will also determine the lowest level of phosphorus you can achieve in your effluent. In the most basic division, phosphorus is dissolved, soluble phosphorus or is in particulate, filterable form. Part.

Is phosphorus in laundry detergent?

Even though phosphates are found everywhere, too much can be a bad thing. Because phosphates are considered nutrients, high concentrations can disturb the balance of an aquatic environment, causing plants, such as algae, to grow rapidly. The discharge of phosphates into waste treatment and sewage systems is regulated.
