The benefits of
polyaluminium chloride products are now widely recognised. This substance not only effectively treats wastewater but also aids in environmental remediation. Currently, the most significant environmental impacts stem primarily from chemical plants, smelting works, petrochemical facilities, paper mills, and textile dyeing factories. It remains imperative to rigorously address pollution at its source.
With societal advancement, environmental protection and governance have become paramount. The efficacy of polyaluminium chloride in water purification is undeniably pronounced. Typically containing 25%-30% active substance, it offers low-cost purification with excellent results. It is effectively applied in non-ferrous metal smelting, electroplating, and battery wastewater treatment, particularly in industrial effluent management where usage volumes are substantial. Its usage volume is substantial. The remarkable efficacy of polyaluminium chloride in industrial wastewater treatment stems from its large molecular structure and strong adsorption capacity. It requires minimal dosage while maintaining low cost. Coupled with excellent solubility, high reactivity, and rapid sedimentation, its purification capability exceeds that of other water treatment products by two to three times. It exhibits minimal sensitivity to pH and temperature variations, ensuring straightforward operation.
As a representative inorganic flocculant, polyaluminium chloride offers low cost, straightforward application, and extended storage stability. These advantages position it as a widely adopted, user-friendly solution across numerous water treatment processes, serving as an indispensable component in wastewater treatment.
Manufacturers primarily produce polyaluminium chloride using calcium powder as the main raw material, synthesised with industrial hydrochloric acid, calcium chloride, and lime. The production process employs drum drying technology. The resulting polyaluminium chloride is primarily utilised in sewage treatment. Its colour tends towards brown, primarily due to the addition of iron powder. The greater the quantity of iron powder added, the darker the colour becomes. When iron powder exceeds a certain quantity, the product is termed polyaluminium chloride iron. It demonstrates remarkable efficacy in wastewater treatment. Although numerous types of polyaluminium chloride products exist, the flocculation performance ultimately determines both subsequent usage effectiveness and cost efficiency. Therefore, selecting the appropriate polyaluminium chloride product type remains essential for enhancing water quality and reducing purification costs.
