Do you know the phosphorus removal effect of ferric sulfate nine-hydrate

Ferric sulfate nine-hydrate is a well-known sewage treatment agent, which is widely used in sewage treatment process and loved by most manufacturers.

What is the phosphorus removal efficiency of polyaluminium chloride wastewater? It is advisable to test the key components of TP in wastewater. If polyaluminium chloride is used to treat wastewater, the phosphorus content in the product can be detected and then applied.

Ferric sulfate nine-hydrate proposes that the use of polyferric sulfate is more effective than polyaluminium chloride, and may also reduce costs. Here is a summary of the reasons why the use of polyaluminium chloride is ineffective.

1. Demand for phosphorus removal of polyaluminium chloride depends on the form of phosphorus. If orthophosphate is the standard, polyaluminium chloride may be used to treat it, but if TP contains more metaphosphate, organic phosphorus, etc.

Pure use of polyaluminium chloride can not be dealt with, the need for strong oxidant pretreatment will be partial phosphorus, organic phosphorus oxidized into orthophosphate, then treated with polyaluminium chloride.

2. Ferric sulphate nine-hydrate has comparative effect, but with the reduction of production cost of many manufacturers, it makes more polyaluminium chloride itself contain higher phosphorus.
