Polyaluminium Chloride, abbreviated as PAC or polyaluminium, refers to a single product regardless of whether termed polyaluminium chloride, polyaluminium, PAC, or polyaluminium. Poly Aluminium Chloride is an emerging water purification agent developed from basic aluminium chloride. The active ingredient in both is aluminium trioxide. However, due to their differing compositions, their mechanisms of action are not identical. Nevertheless, PAC and basic aluminium chloride are distinct products. PAC finds application in treating various types of sewage, wastewater, and purifying domestic water supplies. It is also utilised across multiple industries, including papermaking, fabric wrinkle prevention, and cement concrete production. Market demand for this product remains substantial.
As a widely utilised water treatment chemical in sewage processing, polyaluminium chloride extends beyond wastewater treatment to other industrial sectors. Consequently, certain considerations are essential when procuring this product to ensure suitability.
The required type of polyaluminium chloride varies depending on the application. For instance, industrial-grade polyaluminium chloride is used in industrial wastewater treatment, while drinking water-grade polyaluminium chloride is employed in potable water treatment. Food-grade polyaluminium chloride is used in food additives. Industrial-grade polyaluminium chloride is typically brown in colour. Drinking water-grade polyaluminium chloride is predominantly pale yellow, while food-grade polyaluminium chloride is typically a white powder. The differing applications clearly justify these distinctions. Therefore, when employing polyaluminium chloride, selection must be based on specific requirements. Only by choosing the appropriate polyaluminium chloride product can optimal results be achieved, thereby representing a cost-effective approach.
Regarding polyaluminium chloride types, distinctions exist between liquid and solid forms. Liquid polyaluminium chloride is less expensive but presents logistical challenges, incurring higher transportation costs. Solid polyaluminium chloride pricing is determined by its concentration. Currently, concentration serves as a critical factor when procuring polyaluminium chloride products. Polymerised aluminium chloride with varying concentrations yields differing performance outcomes and exhibits significant price disparities. Concentrations typically range at 30%, 28%, and 26%. This concentration refers to the aluminium oxide content within the polymerised aluminium chloride, essentially its purity. It can be stated that the concentration of polymerised aluminium chloride is one of the factors determining its price.
