There are many water purification equipment, but the applicable fields are completely different. Sand filters are suitable for use in the sewage treatment industry. We all know that there are many impurities in sewage, and the components are extremely complex.
Especially the recycling and treatment of sewage and industrial sewage in modern cities requires the use of special equipment. Need to use this kind of equipment, this kind of equipment is completely different from some other filtering equipment. Nowadays, the sewage treatment or industrial sewage treatment in many cities basically requires the use of sand filters.
The sand water and air are rubbed violently under the action of compression, so that the trapped impurities can be cleaned up and then cleaned. Because of gravity It can be added to the filter bed from top to bottom, and the sand washing water can be discharged separately, which completes the entire cleaning process. The filtering principle of this kind of equipment is very simple.
The sewage can directly enter a diversion channel from the water inlet pipe, and then it needs to enter the sand filter tank and then pass through the filter to leave a part of the cyclone on the bed, and then It becomes very clean filtered water, and the filtered water needs to flow further to the outlet pipe, and then flow out of the filter.
