Phosphorus removal effect of polyaluminium chloride

Polyaluminium chloride is well known as a sewage treatment agent, and its application in sewage treatment technology is greatly favored by most manufacturers. What is the effect of removing phosphorus from polyaluminium chloride wastewater? The phosphorus removal from sewage can be tested to detect the main components of TP in the wastewater. If it is treated with polyaluminium chloride, the phosphorus content in the product can be detected and used. Lvyuan manufacturers recommend that you use poly ferric sulfate to achieve better results than polyaluminium chloride, and it can also reduce costs. The following small series will give you a summary of the reasons for the poor use of polyaluminium chloride.

Phosphorus removal by polyaluminium chloride depends on the presence of phosphorus. If it is based on orthophosphate, it can be solved by using polyaluminium chloride. However, if TP contains more metaphosphate, organic phosphorus, etc., it is purely used. Polyaluminium chloride can not be solved, and it needs to be pretreated with strong oxidant to oxidize phosphorus, organic phosphorus to orthophosphate and then to polyaluminium chloride.

The theoretical effect of polyaluminium chloride removal is ideal, but with many manufacturers reducing production costs, the current polyaluminium chloride itself contains higher phosphorus.
