Quartz sand filter is the use of quartz sand as a filter medium, under a certain pressure, the water with high turbidity through a certain thickness of granular or non-granular quartz sand filtration, you effective interception to remove suspended solids in the water, you machine, colloidal particles, microorganisms, lv, smell and some heavy metal ions, etc., and finally achieve a filtration equipment that reduces water turbidity rotary vacuum disc filters and purifies water quality.

Scope of application of quartz sand filter:
(1) For industrial water, domestic water and municipal water supply systems that require effluent turbidity ≤ 5mg/L to meet drinking water quality standards;
(2) Removal of suspended solids and solids in industrial sewage;
(3) It can be used as pretreatment equipment in the ruanization and desalination system of ion exchange method, and the crude filtration equipment of industrial feed water with low water quality requirements;
As well as used in swimming pool circulation treatment system, leng but circulating water purification system, etc.

Quartz sand filter working principle:
The operation of the continuous filter can be divided fine bubble diffuser into two relatively independent and simultaneous processes of raw water filtration and filter material cleaning zaisheng. Both are done in different positions of the same filter, the former powered by the high differential or the lifting of the pump, while the latter is done by compressed air.
Quartz sand filter is the use of one or more filter media, room temperature operation, acid and alkali resistance, oxidation, pH application range of 2-13. The system is equipped with perfect protection devices and monitoring instruments, and has a backwash function, dirt and other pollutants are quickly washed away, less water consumption, according to user requirements can be set up fully automatic function. Under a certain pressure, the original solution is flocculated, adsorbed and intercepted through the contact of the medium to remove impurities, so as to achieve the purpose of filtration. The fillers contained in it are generally: quartz sand, anthracite coal, granular porous ceramics, manganese sand, etc., and users can choose to use them according to the actual situation. Its filtration accuracy is Dissolved Gas Flotation between 0.005-0.01m, which can effectively remove colloidal particles and polymers.
Huo carbon filter is mainly used to adsorb free lv in water (adsorption force of up to 99 percent), and also has a high removal rate for you and color. It is a pretreatment equipment for the process of ruanization and desalination system to produce pure water. The filter media is huo-based carbon. The main materials of the equipment are carbon steel anti-corrosion, FRP and stainless steel.
