Water filtration industry "elite" - quartz sand and activated carbon filter difference revealed!
Quartz sand filter - reduce water turbidity
Quartz sand filter is the use of quartz sand as a filter medium, under the corresponding pressure, the high turbidity of water through the corresponding thickness of granular or non-granular quartz sand filtration, interception to remove the suspended matter in the water, colloid particles, microorganisms, to reduce the turbidity of water, water purification effect of a filter equipment.
Activated carbon filter - remove odor and color in water
The main application of activated carbon filter supplies is activated carbon, activated carbon has strong adsorption, can filter the water containing odor, different color, residual chlorine, etc. The use of different properties of activated carbon, water treatment effect is different. The filter is used in the pretreatment of pure water to protect the ion exchange resin and ensure the stable operation of the whole system.
The difference between the two -- three aspects
1. Filter material
Quartz sand filter is filled with quartz sand filter material;
The activated carbon filter is filled with activated carbon filter material.
2. Adsorption principle
Interception solid particles: quartz sand filter is mainly filled with fine quartz sand dense, after interception of particulate matter impurities in the water, the effect of organic matter dissolved in water, ions and other impurities is very small; It mainly traps solid particles that are insoluble in water.
Adsorption of organic matter in water, colloidal: activated carbon filter is mainly through the activated carbon of a large number of micropores, these micropores have a strong adsorption force, can absorb organic matter in water, colloids, ions and other impurities.
3. Use effect
High hardness of filter material is not easy to break: quartz sand filter because quartz sand hardness is higher, more solid. So in operation or backwash, is not easy to break when washing. Some small amount of broken quartz sand will be drained by backwashing water, so with the extension of the filter time, the filter material will be reduced accordingly.
Water quality is easy to turn black: activated carbon filter can absorb organic matter in water and different color odor, but with the passing of time, activated carbon filter in the pores of the activated carbon and the adsorption between the particles gradually increased, so that the filter before and after the pressure difference increased, until the failure, resulting in the activated carbon filter water black phenomenon.
How to choose? -- The standards for purifying water quality are the basis
1. Quartz sand filter is mainly used to remove suspended solids in water. The filtration equipment and other water purification equipment cooperate with each other, widely used in water supply treatment, circulation system water treatment wastewater treatment and other water treatment technology.
2, activated carbon filter is mainly used in the adsorption of free chlorine in water, organic matter and saturation is also a strong sludge load, is soft, desalting system software water treatment processing equipment.
The difference between quartz sand filter and activated carbon filter is key in the filling between the two, the basic principle of adsorption and adsorption material is not the same. Because of the adsorption of the two substances are not the same, therefore, in the selection of quartz sand filter and activated carbon filter in the case of purifying water quality standards for selection.
