Alum manufacturing equipment tells you the role of aluminum sulfate in water treatment。-体育-www.liusuanlvshebei.com

The main uses of aluminum sulfate in water treatment are widely used in household and industrial wastewater, alum manufacturing equipment for papermaking, printing, tanning, cement building materials, and wood protectants.

Aluminum sulfate can be used as a mixture of suspended particles accumulated in wastewater, and is used as a phosphorus removal agent, defluoriner, decolorizer, deodorizer for petroleum wastewater, acid scheduling for alkaline wastewater, and flotation for mineral water wastewater in deep wastewater treatment.

The reason why aluminum sulfate is used for wastewater treatment is that it dissolves in water to form aluminum oxide and aluminum ions. These hydrolyzed products contain positive charges of aluminum, which are attracted by small suspended particles of negative ions in water. The alum manufacturing equipment neutralizes the charges on the surface of the suspension, eliminates the charges on the surface of the suspension, separates them from the principle of same-sex charges being suspended from each other, and then aggregates together to form particles that exceed the buoyancy of water, accumulating at the bottom of the water.

Another product, alumina, reacts with water: Al3++3H20=Al（OH）3+3H+， Aluminum hydroxide is an adsorption compound that can adsorb and condense small suspended particles in water, reaching the level of gravity accumulation, and actively accumulating under the action of aluminum hydroxide.
