Exceed and strain technology that each use in the epurations of mineral water extensively, separate organic macromolecule material, colloid, ultra particle young, bacterium,etc.ses for the main fact, Fall turbid clarifying , except that and macromolecule material finish concentrating and it has to be very remarkable result fungus to degree of depth. Water through in strain by to device ,from the impurities of waters remove all at chlorides, bacteria,etc. various kinds of harmful substances at type chemical compounds phenols colloids, And at water helpful all kinds of mineral substances stay among water, quality of water reach national standard who mineral water appoints at 100% by index. Used in counter-infiltration and make water system too, protect RO's membrane, improve and make the quantity of quality of water, increase water yield. It is the domestic most advanced exceeding straining the water treatment equipment of mineral spring at present.
