Drinking water treatment quartz sand filter system, 1.Mineral / pure water, 2.Capacity:0-20 tons /h, 3.CE,ISO - details see: https://www.machineto.com/drinking-water-treatment-quartz-sand-filter-system-10024997

Drinking water treatment quartz sand filter system

Sand filter :
1.Inside filled medium: quartz sand (made from crushing natural quartz)
2.Principle: the filter purifying water with granular or ungranular material of certain thickness.
3.When there are too many impurities in filtering layer, the hole shall be blocked and then stream resistance shall increase, filtering speed shall reduce.
4.So as to keep original filtering speed, it must be washed repeatedly to get rid of all impurities leaving in filtered material.

Active carbon filter :
1.It is compose with active carbon layer and supporting layer. Active carbon has good holes. The holes have high adsorbed ability. Because of this, it is used in many industries. After working for a long time, active adsorb many material to tend to a saturation state. So, it we should change active carbon or make it regenerates.
2.The supporting layer is used in preventing the loss of active carbon from the equipment; it is also helpful to make water equality.

Sodiun ion exchanger :
The ion exchange soften machine is used for cutting down hardness of water. Raw water goes through the exchanger from top to bottom, to be soften by the sodium ion-exchanger inside the divice. The positive ions of magnesium and calcium are exchanged with that of sodium. Then the raw water become soft water containing very few magnesium and calcium ion
