Can Polyaluminium Chloride Be Used for Phosphorus Removal

Polyaluminium chloride (PAC) can remove phosphorus. As a commonly used coagulant and flocculant in water treatment, PAC has significant applications and its phosphorus removal effect is widely recognized. Let's follow the polyaluminium chloride manufacturer Qili to learn more details.

The principle of phosphorus removal by polyaluminium chloride:

The principle of polyaluminium chloride removing phosphorus is mainly through chemical coagulation and sedimentation. When PAC is hydrolyzed in water, it forms various aluminum salt ions and hydroxide ions. These aluminum ions carry positive charges and have adsorption and chemical bonding capabilities. When they encounter phosphates in wastewater, a chemical reaction occurs, forming insoluble aluminum-phosphorus compound precipitates, thereby removing phosphorus from the water.

The efficiency of PAC in removing phosphorus is influenced by several factors, including the dosage of polyaluminium chloride, the pH value of the water body, reaction time, and water quality conditions. Rational control of these factors can optimize the phosphorus removal efficiency of PAC. According to relevant data, as the amount of PAC added increases, the total phosphorus (TP) removal rate will significantly improve, reaching up to about 96.8%.

Advantages of phosphorus removal by polyaluminium chloride:

Efficiency: polyaluminium chloridehas a high phosphorus removal capacity, significantly reducing the phosphorus concentration in water bodies.

Stability: The precipitate particles formed by polyaluminium chloride and phosphorus are large and stable, not prone to desorption, thus the phosphorus removal effect is lasting.

Wide applicability: PAC is suitable for various types of water bodies, including tap water, groundwater, river water, lake water, etc., and maintains stable phosphorus removal effects under different water quality conditions.

Resource recovery and utilization: The precipitate generated during the PAC phosphorus removal process can be recovered and utilized as fertilizer, achieving resource recycling.

In summary, polyaluminium chloride is an effective phosphorus removal agent with broad application prospects in the field of water treatment.
