DIAMOND FILTRATION TECHNOLOGY

What makes the Diamond Filter Different and Unique?
It is its Unique ability to use fine quartz sand
to achieve high quality water filtration!

Conventional sand filters remove contaminants in the 15 to 30 micron range. The state-of-the-art design of the DWSI system sets new efficiency standards for filtration:
  • High-grade Quartz media and system design allows filtration down to 0.5 micron (nominal).
  • Higher flow rate per square foot of media surface.
  • Less space required than traditional systems.
  • Less water needed for backwashing.


THE DIAMOND WATER FILTRATION CONCEPT

The DWSI filtration system utilizes a combination of pressure and turbulent media to attain high quality water filtration.

The water to be filtered enters the top distributor of the filter vessel under pressure in a cross-flow pattern.

As it passes across the top of the media, the filter media tightens up, not allowing contaminates to penetrate the media bed.The water ‘scours’ the media surface as it passes across the top of the bed.

This suspended media forces most of the contaminants to remain above the media allowing the clean water to penetrate through the media.

Once the area above the media becomes saturated, the filtration system will require backwashing.Since the contaminant has not penetrated the media and is mainly in suspension, backwashing is done with little effort.

The flow is reversed to loosen the media and allow the system to discharge all of the contaminants.

DWSI filtration systems require less time and water than conventional filtration systems to unload all of the contaminants.


COMPARISON OF CONVENTIONAL SAND FILTRATION
VERSUS DIAMOND WATER SYSTEMS:


CONVENTIONAL:

  • Remove contaminants in the 15 to 30 micron range.
  • Flow rates less than 5-10 gallons per square foot of media surface area.
  • May require up to 125% of the filter flow rate for backwash.

DIAMOND WATER SYSTEMS:

  • Will effectively filter down to nominal 0.5 microns.
  • Flow rates at or above 15 gallons per square foot of media area (depending on micron extraction rating of media).
  • Footprints that are considerably less than a conventional system.
  • Low backwash flow rates (generally 50% of vessel design flow, but is system dependant).
