Technical Description    

The core technique of JY filter adopts discs filtration principle. Through deeply pressed grooved plastic discs to achieve combination of surface filtration and depth filtration.  There are thin grooves on the surface of the discs, the grooves in opposite direction between discs making many crossed points Therefore the crossed points form many chamber and irregular channels blocking suspendid particles, up to 85%.

When there are many inpurities accumulated in the grooves between discs, inlet and outlet will change opposite direction, compressed discs open automatically and comprssed water injects to discs and the discs rotate quickly, the backwash process completed and the inlet and outlet direction then changed back.

^{Ready for shippment:}

Disc filters are widely used as pre-filters in industrial and commercial areas such as:

• desalination;
• chemical industry;
• food industry;
• textile industry;
• iron and steel industry;
• pharmaceutical industry;
• paper industry;
• other fields of industry.

Also, disc filters are used in the manufacture and operation of:

• power plants;
• industrial and commercial ventilation and air conditioning systems in buildings;
• building materials;
• irrigation systems;
• wastewater treatment;
• municipal water supply;
• in the areas of emergency situations,
• etc.
