Phosphorus is the eleventh most abundant element in earth. If soils are deficient in phosphorus, food production becomes restricted, unless the nutrient is added in the form of fertilizers. Hence, to increase food production, an adequate amount of phosphorus is required. Phosphorus is an essential nutrient required for plant growth. It helps in root development, plant maturation, and seed ...Get Price

Phosphorous removal from wastewater
This process is usually quite slow. Normally secondary treatment can only remove 12 mg/l, so a large excess of phosphorous is discharged in the final effluent, causing eutrophiion in surface waters. New legislation requires a maximum concentration of P discharges into sensitive water of 2 mg/l. Phosphorous removal processes. The removal of phosphorous from wastewater involves the ...Get Price
