Common Steps in Water Treatment System

Drinking water sources are subject to contamination and require appropriate treatment to remove disease-causing agents. Public drinking water systems use various methods of water treatment to provide safe drinking water for their communities. Today, the most common steps in water treatment used by community water systems (mainly surface water treatment) include:


Coagulation and Flocculation

Coagulation and flocculation are often the first steps in water treatment. Chemicals with a positive charge are added to the water. The positive charge of these chemicals neutralizes the negative charge of dirt and other dissolved particles in the water. When this occurs, the particles bind with the chemicals and form larger particles, called floc.



During sedimentation, floc settles to the bottom of the water supply, due to its weight. This settling process is called sedimentation.



Once the floc has settled to the bottom of the water supply, the clear water on top will pass through filters of varying compositions (sand, gravel, and charcoal) and pore sizes, in order to remove dissolved particles, such as dust, parasites, bacteria, viruses, and chemicals.



After the water has been filtered, a disinfectant (for example, chlorine, chloramine) may be added in order to kill any remaining parasites, bacteria, and viruses, and to protect the water from germs when it is piped to homes and businesses.

Pre-treatment Machines Active Carbonated Filter Quartz Sand Filter

1.Quartz sand filter

High nickel 304 and 316 stainless steel tanks are used for automatic welding and double-sided forming welding. The internal and external polishing treatment reaches the sanitary standard and the internal is filled with high-quality quartz sand. The suspended solids, colloids and other harmful substances in the water are removed from the top to the bottom by using the deep filtering principle.

2.Activated carbon filter

304, 316 material tank body, automatic welding, double-sided forming welding, containing high-quality activated carbon, plus the chemical liquid or steam disinfection technique developed by Zhongguan. So that the activated carbon filter can not only better absorb the taste residual chlorine and organic matters in the water, but also not become a hotbed of bacteria.
