When choosing coagulants for phosphorus removal, it’s common to prioritize the cost of the chemical as a key factor in the decision-making process. However, a myopic focus on only the price tag can lead to overlooking operational-based savings. Evaluating factors such as dosage rates, sludge production and clarifier performance can lead to a well-informed decision that maximizes savings throughout the entire treatment process.
ClariPhos™, a unique coagulant made with rare earth elements, offers several advantages that can significantly improve the cost-effectiveness of phosphorus removal.
Typically, ClariPhos dosed at 30 to 70% lower rate than alternatives. This lower dose is possible because ClariPhos binds to phosphorus at a 1:1 molar ratio. Al/Fe coagulants bind at a ratio of approximately 5:2, and can rise as high as 8:1 to achieve higher levels of phosphorus removal. Lower dose rates also mean fewer totes need to be shipped, handled and stored.
ClariPhos can reduce sludge production by as much as 50%, thanks to its reduced dosage rates and dense precipitate. The reduction in sludge volume also helps lower sludge dewatering costs and dramatically decreases trucking costs.
ClariPhos forms a dense, stable precipitate that settles up to two times faster than alternatives. This is because the atomic weight of rare earth elements is much higher than aluminum or iron alternatives. As a result, ClariPhos can improve clarifier performance, reduce carryover of suspended solids and potentially eliminate the need for tertiary filtration systems.
