Adsorption – Phosphate
The extraction of phosphorus presents a challenge for all waste water treatment systems. Since phosphor is at the root of problems like algal blooms and lake eutrophication, regulators have imposed highly stringent legislation regarding phosphor concentrations allowed in water discharges. Current technologies are effective in producing a primary significant drop in the water’s chemical load, but phosphorus becomes increasingly difficult to extract at lower concentrations. An effective way to capture phosphorus in weak concentrations is therefore being sought by the waste water industry.
Inorganic phosphate (phosphate or orthophosphate) is the major source of phosphorus in the discharge of waste water treatment systems. It is also the source of phosphorus that is easiest absorbed by algae and other organisms. In microsphere trials, 50 mg MAT200 were added to a solution containing 50 mg phosphate. The results showed that the microspheres were able to adsorb 40% of their weight in phosphates.
