Polyaluminum chloride as a new water purification agent, its excellent water purification effect and the scope of use is very large, so does polyaluminum ferric chloride have the effect of sewage phosphorus removal?

Phosphorus is one of the pollutants with high content in urban sewage at present. A large amount of phosphorus will cause eutrophication of water body, which will not only harm aquatic organisms, damage the water environment, but also cause serious damage to the environment. Therefore, wastewater phosphorus removal is also one of the indispensable standards.

What is the effect of PAFC on phosphorus removal? After long-term practice and summary, it is found that the trivalent aluminum ion in polyaluminum ferric chloride can react with the soluble phosphate in sewage, so as to produce sediment to achieve the effect of phosphorus removal. Moreover, polyaluminum ferric chloride has a strong coagulation effect, which can adsorb and bridge the charged phosphate ions in the sewage, and make the phosphate ions in the sewage reach the removal effect.

The pH value of polyaluminium ferric chloride is between 4-9, and if the pH value is between 6-7.5, it can achieve better phosphorus removal effect, and the maximum phosphorus removal rate can reach more than 96.6%.

At present, polyaluminium ferric chloride can also be used as a very good dephosphorization agent, which can not only achieve good turbidity and decontamination effect, but also achieve very good removal effect on phosphorus, nitrogen, COD, heavy metals and other pollutants in sewage.
