What are the methods of industrial water treatment?

Coagulation refers to adding a certain dose of chemicals to water. These chemicals hydrolyze in water and collide with colloidal particles in water, resulting in electric neutralization, adsorption, bridging and net capture, thus forming large floc particles, which settle down from water and play a role in reducing suspended matter and colloid.

Second, the medium filtration

Media filtration refers to the process that water passes through the bed composed of quartz sand or anthracite under the action of gravity or pressure, and the particulate pollutants in the water are intercepted by the media, thus realizing the separation from water. Particle medium filtration is based on the working process of "filtration-clarification", which removes particles, suspended solids and colloids in water.

Industrial water regulation

In industrial water treatment, the task of pretreatment process is to treat the water source of industrial water-surface water, groundwater or urban tap water, so that it can reach the influent quality index allowed by the subsequent water treatment device, so as to ensure the long-term safe and stable operation of the water treatment system and provide high-quality water for industrial production.

The pretreatment targets are mainly suspended solids, colloids, microorganisms, organic matter, free residual chlorine and heavy metals in water. These impurities will adversely affect water treatment equipment such as electrodialysis, ion exchange, reverse osmosis and sodium filtration.
