How it works

Feed water is pumped from the borehole and supplied at 65 psi (0.45 MPa) to the aerator-degasifier (1) and here dissolved gasses are removed from the water and atmospheric air oxidizes bivalent iron and partially  anions of manganese.

Further, feed water flows down the "hydro-robot" (2) and through the distribution system (3) and arrives into the hydro-automatic filter with the polymer floating filter media - PFFM (4) where impurity particles are filtered out of the water.

After filtration, treated water gravity-flows into the filtrate collector via the discharge pipe (6), and your delivery pump forwards purified water for consumption and usage.

Clean Water Technologies works with any source of water.

BORE WATER is a typical major source of high volume water supply and a primary application for our technology in providing a complete packaged least total cost solution for a clean water supply.

By analogy, we do the work of a bubbling brook from spring to stream, and more --

Process Summary

You provide bore water to our aerator column at 65 psi and the rest is automatic

  • gas evacuation,
  • water fragmentation with extreme mixing and oxidation,
  • poly floating filter media surface reactions,
  • poly floating filter fine filtration,
  • automatic sensing and backwash activation (or optionally timed).


No chemicals introduced.

No power supply required.

Very low maintenance for a lifetime of service.

As fouling occurs naturally in the filter, the water level in the hydro-robot rises, triggering the filter to switch into backwash mode. Purified water from above the screen over the PFFM filter bed (5) is drawn down by the siphon action, expands the filter bed, and washes out the accumulated impurities.

When the water level above the screen (5) drops down below a pre-set point (established during commissioning), the hydro-robot stops the backwash and switches the filter into a new filtration cycle.

Backwash water is gravity discharged from the receiver and is disposed of in a sump, or additionally treated according to the customer's requirements.
