Phosphate in Wastewater — Water Library - H2O Labcheck

As mentioned, phosphate removal strategies can be separated into two main categories: chemical methods and biological methods. When phosphate is dissolved in wastewater, it cannot be separated out by filtration; coagulants and flocculants must first be added to form insoluble phosphate-containing compounds that precipitate out of solution.2 ...

Aquarium Filter: The Complete Guide to Aquarium …

Biological Filtration. A biological filtration in an aquarium is achieved by passing water over a medium rich in beneficial bacteria. The beneficial bacteria converts ammonia and nitrites into less dangerous nitrates. This is a part of the nitrogen cycle. Biological filtration enhances this process by increasing the surface area for these ...

Effects of phosphate and hydrogen peroxide on the ...

Generally, phosphate removal occurs with the addition of coagulants in coagulation-sedimentation-filtration processes, which results in phosphorus-deficient water at a concentration of 0.01 mg/L (Nishijima et al., 1997). However, the impact of phosphorus on BAC biofilms, particularly the EPS characteristics, has not yet been fully explored.
