Multi - medium quartz sand pressure filter

Product Introduction

Quartz sand filter, the scientific name of shallow medium filter, it is the use of quartz sand as the filter medium, under a certain pressure, the high turbidity of water through a certain thickness of granular or non-granular quartz sand filtration, effective interception and removal of suspended matter in the water, organic matter, colloid particles, microorganisms, chlorine, odor and some heavy metal ions, etc.  Finally achieve the reduction of water turbidity, water purification effect of a perfect filtration equipment.

Principle of Operation

The operation of continuous filter can be divided into two relatively independent and simultaneous processes: raw water filtration and filter material cleaning and regeneration. The two are completed in different positions of the same filter, the former power depends on the high position difference or pump lift, while the latter is completed by compressed air.

Quartz sand filter is the use of one or several filter media, normal temperature operation, acid and alkali resistance, oxidation, pH range is 2-13. The system is equipped with perfect protection device and monitoring instrument, and has backwash function, dirt and other pollutants are quickly washed away, less water consumption, according to user requirements can be set automatic function. Under certain pressure, make the stock solution through the medium contact flocculation, adsorption, interception, remove impurities, so as to achieve the purpose of filtration. Its internal packing is generally: quartz sand, anthracite, granular porous ceramics, manganese sand, etc., the user can choose to use according to the actual situation. The filtration accuracy is between 0.005 and 0.01m, which can effectively remove colloidal particles and macromolecular organic matter.

Activated carbon filter is mainly used for adsorption of free chlorine in water (adsorption power up to 99%), and has a high removal rate of organic matter and chroma. It is a pretreatment equipment for the process of making pure water by softening and desalting system. Filter media for activated carbon. The main material of the equipment is carbon steel anticorrosion, glass steel and stainless steel.

Scope of application

Quartz sand filter operation can realize automatic control, high filtration efficiency, small resistance, processing flow, less recoil times. Widely used in pure water, food beverage water, mineral water and electronic, printing and dyeing, papermaking, chemical industry water quality pretreatment and filtration of industrial sewage after secondary treatment. It is also used for deep filtration of water reuse system and swimming pool circulating water treatment system. It also has a good removal effect on suspended solids in industrial wastewater.

1, mainly used for water treatment turbidity removal, softening water, electrodialysis, reverse osmosis pre-treatment, can also be used for surface water, groundwater and other aspects. It can effectively remove suspended matter, organic matter, colloid, sediment and so on.

2, can be widely used in electronic power, petrochemical industry, metallurgy electroplating, paper textile, pharmaceutical dialysis, food and beverage, drinking water, factory water, swimming pool and so on. It can meet the needs of liquid filtration in various industries.
