Aluminium Sulphate in water treatment
Main Features
Excellent coagulation performance: Aluminum sulfate can quickly form a colloidal precipitate, quickly precipitating suspended substances in the water, thereby improving water quality.
Wide applicability: Suitable for all types of water bodies, including tap water, industrial wastewater, pond water, etc., with good applicability and versatility.
PH adjustment function: It can adjust the PH value of water within a certain range, which helps to improve the stability and applicability of water.
Non-toxic and environmentally friendly: The product itself is non-toxic and harmless, environmentally friendly and complies with relevant environmental protection standards.
