Water resources are the foundation of human life and industrial development, but with the continuous intensification of industrialization and urbanization, the problem of water pollution is becoming increasingly prominent. Among them, suspended solids, organic matter, heavy metal ions and other components in sewage pose a serious threat to water quality, so advanced water treatment technologies are needed to purify the water source. As a flocculant, polyaluminium chloride can effectively agglomerate suspended solids and organics into larger agglomerates, so as to facilitate subsequent sedimentation, filtration and separation operations.
The principle of poly Aluminium chloride is to form small Aluminium hydroxide colloids in water by releasing aluminum ions and Hydroxide ion ions. These colloids can adsorb suspended solids and organic matters and aggregate into larger flocs. At the same time, aluminum ions can also neutralize negatively charged substances in water, promoting the aggregation of suspended solids. Therefore, PAC is often used in water treatment to flocculate particles and organic matter in wastewater, making it easier to treat.
In the aspect of drinking Water purification, polyaluminium chloride can be used to remove turbid substances and chroma in water, and improve the transparency and quality of water. In industrial water treatment, PAC can be used to purify circulating water, cooling water, etc., prevent equipment blockage and corrosion, and maintain the stability of industrial production.
Polyaluminium chloride has many advantages over traditional ferric salt flocculants. Firstly, PAC has a fast flocculation speed and high flocculation efficiency, which can quickly coagulate suspended solids in a short period of time, thereby reducing processing time and equipment costs. Secondly, compared to iron salt flocculants, PAC produces larger flocs that are easier to precipitate, reducing the difficulty of subsequent filtration and separation steps.
In addition, when polyaluminium chloride is used in drinking water, it will not produce carcinogenic chloroform substances, which is more reassuring than chlorine disinfection by-products.
However, the use of polyaluminium chloride also has some challenges. Excessive aluminum ions may have certain impacts on the environment and health, therefore strict dosage control is necessary. In addition, the preparation process of PAC involves chemical reactions and energy consumption, which requires attention to environmental protection and resource sustainability.
