Polyaluminium Chloride is a widely recognised water purification product. Its efficacy in water treatment is beyond doubt. However, being a high-molecular-weight inorganic flocculant, it is categorised by its content into 30%, 28%, and 26% variants. Different contents yield distinct applications and usage scopes, necessitating selection based on specific requirements.
What distinguishes products with different concentrations? The 30% concentration product boasts higher purity. It is predominantly used for purifying drinking water and removing fluoride and chlorine from wastewater. This product is typically white in colour. The 28% concentration product is commonly employed in water treatment plants for water purification and treatment. The 28% concentration is the most common variant, delivering effective water treatment outcomes in both potable water and sewage processing. The 26% concentration product is comparatively more economical. Its lower alumina content is supplemented with additives such as calcium aluminate powder, hydrochloric acid, bauxite, and iron powder. The presence of iron imparts a brownish-red hue to this product, with darker shades corresponding to higher iron content. Many opt for this product in treating industrial effluents and domestic wastewater. Beyond differing concentrations, it is categorised by form into spray-dried and solid variants. Spray-dried products require extensive contact with water, resulting in higher moisture content and consequently faster purification of wastewater. They are suitable for water treatment processes in industries such as power generation. Solid products, however, represent the more commonly and widely used form, being the preferred choice for most.
Generally, polyaluminium chloride is priced according to its concentration. Higher concentrations indicate greater purity and consequently higher costs. Among all product types, spray-dried varieties command the highest prices. They appear as pale yellow powders. Market offerings exhibit varying colours, including white, yellow, and brownish-yellow. White products typically command prices exceeding three thousand yuan. Yellow variants are priced around two thousand yuan. Brownish-yellow products are comparatively more economical, generally costing approximately one thousand yuan. However, regardless of the product type, selection must be based on the actual water quality conditions during practical application. Choosing the most suitable product achieves the dual objectives of reducing costs and enhancing operational effectiveness.
