Understanding Polyaluminum Chloride: A Key Player in Water Treatment

Introduction Polyaluminum chloride (PAC) is a widely used coagulant in water treatment processes. Known for its effectiveness in removing impurities and improving water quality, PAC has become essential in municipal water treatment facilities, industrial applications, and more. In this article, we’ll explore what PAC is, its benefits, applications, and why it’s a preferred choice for water treatment. What is Polyaluminum Chloride? Polyaluminum chloride is a chemical compound made...

Analysis on the process flow of urban sewage treatment plants

For urban sewage treatment plants in China, most of them are located in important river basins, so the effluent standards are also very high, usually using the first level standard A. The purpose is also to make the treated water regenerative. From the perspective of technical feasibility and economic rationality, the removal of COD, BOD5, nitrogen, and phosphorus should be completed as much as possible within the secondary biological treatment process unit of sewage, especially for the removal...

How to choose PAM?

Differences between CPAM, NPAM, APAM 1、Structure difference CPAM: A linear polymer compound, because it has a variety of active groups, can be compatible with many substances, adsorption to form hydrogen bonds. Mainly because of the flocculent, negatively charged colloids. APAM：It is a water-soluble polymer, mainly used for the flocculation settlement of various industrial wastewater, precipitation and clarification treatment, such as steel plant wastewater, electroplating plant wastewater,...

Technical analysis of chemical removal of phosphorus

Technical analysis of chemical removal of phosphorus 2023-06-30 Poly Aluminium Chloride （Solid） Basis of chemical phosphorus removal The removal of phosphorus has two processes: chemical phosphorus removal and Biochemical disposal of phosphorus. The latter one is a relatively economical method of phosphorus removal. However, because the phosphorus removal process is currently not guaranteed to reach the requirements of 0.5mg/L water outlet standard, as we must need to meet the stable water...

The Main Application Range of Polyaluminum Chloride

In the process of dissolution of polyaluminum chloride, hydroxide ions release a large number of positive charges to absorb the negatively charged ions in water, and the flocs are formed quickly and coarse, with high activity and fast precipitation, so as to achieve the purpose of decomposition and purification of sewage, and the purification effect of high turbidity water is obvious. Applicable to a lot of sewage, can be used in drinking water, domestic sewage, papermaking, chemical industry,...
