  Multimedia & Carbon Filtration


Multimedia Filtration

NHN Multi-media filter are ideal for removal of fine suspended particles present in the source water. The deep-bed systems use 4 layers of media supported by gravel-bed at the bottom. Suspended particles upto 30 micron size are efficiently removed at the system flow rate of 10 gpm/ft. The systems require backwashing to remove the accumulated contamination of suspended particles and rinsed by downflow clean filtered water before use.

Multi-media filters available with Automatic and or manual operational features.

Activated Carbon Filtration

NHN Activated carbon filters are very efficient to remove chlorine, colour, odour,organic elements & pesticide residues by adsorption process. The highly porouscoconut-shell Granular Activated carbon media provides larger surface area for efficient removal of contaminants at higher flow rates

Periodic backwashing advised to clean the Granular Activated Carbon for efficient functioning and longer life of media. Activated Carbon Filters available with Automatic or manual operational features.

  Softener - Single Tank Water Conditioners

NHN Softener are equipped with Cation Exchange Resin media placed on gravel bed to reduce hardness of water. Compounds of Calcium and Magnesium impart hardness to water are responsible for scaling of pipes and earlier fouling of RO membranes. The cation exchange resin replaces calcium, magnesium and other cations present in water with sodium ions.

Systems designed to suit process and regeneration cycle requirements specified by the customer. Easy operations featured with automatic and or manual functions are available.

Fluid enters the filter under pressure and flows through the filter media, holes in the center tubes and perforations in the rods that hold the cartridges in place. As the fluid continues its path, it flows upward past the top seat where it splits over into the standpipe as it hits the filter's domed lid. Notice the top of the standpipe is at high point of the filter. Also, note the filter catridges are sealed at the bottom and held in place with threaded pipe caps. This unique design offers the following significant advantages:

  • No Air Entrapment During Operation
    Air entrapment during operation is eliminated because the outlet is located at the high point of the filter above inlet.
  • No Fluid By-pass During Servicing
    Fluids cannot by-pass filters during servicing because the filter's outlet (top of standpipe) is located above the filter's inlet. A significant advantage in critical filtration applications.
  • Pressure Rated
    Industrial Filters may be safely used in pressures up to 150 psi.
  • Fail-Safe Lids
    Lids come standard with wing nuts so they may be easily opened without tools. Multiple studs provide
