What is the treatment process of water treatment?

May 31, 2018

Wastewater tertiary treatment generally contains the following: primary treatment is it through mechanical processing, such as grating, precipitation or air float, purify sewage contains stones, sandstone and fat, iron, manganese ion, grease, etc.

Secondary treatment is biological treatment, and the pollutants in sewage are degraded and converted to sludge under the action of microorganisms.

Tertiary treatment is the depth treatment of sewage, which includes the removal of nutrients and the disinfection of sewage by adding chlorine, ultraviolet radiation or ozone technology.

Depending on the target and water quality of the treatment, some sewage treatment processes do not include all of the above processes.

Pure water treatment technology, depending on the original water quality.

If the raw water is municipal water, the general process is.

Sand filters - activated carbon filters - soften (optional) - security filters - reverse osmosis - uv disinfection - produce water.

If it is normal surface water, before entering the above process, sterilize and add flocculant.

If it is well water, remove iron manganese filter after sand filtration.

Water is recycled and purified.

Quartz sand filtration is one of the most effective methods to remove suspended solids in water, which is an important unit in sewage treatment, wastewater reuse and water treatment.

The effect is to further remove the flocculating pollutants in the water, which can achieve the purpose of clean water through the interception, settling and adsorption of the filter material.
