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 ...

Get MoreGenerally, 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.

Get MoreZ Rex said: Bingo. Phosphates will latch on to the rock and sediment until the rate of adsorption equals the rate of release, then it will be in equilibrium, with some phosphates leaving the rock but phosphate in the water binding to the now empty sites. If you put a rock that was in a high phosphate tank into a tank with low phosphates then it ...
Get MoreChemical filtration is one of three different types of filters that can be used in your aquarium. The other two are biological and mechanical filtration. As the name suggests, this is a filter that specifically removes chemicals from your aquarium.
