Zero discharge of waste water means that after repeated use of industrial water, all (more than 99%) of the salt content and pollutants in this part are highly concentrated into waste water for recycling, and no waste liquid is discharged from the plant. The salts and pollutants in the water are discharged from the plant in solid form after concentration and crystallization and sent to the waste treatment plant for landfill or recycled as useful chemical raw materials.
