Potable Water Purifier For Pressurised Systems For Buildings
First Claim
Patent Images
1. A method of purifying water by a water purified to make it potable, located at the “
- point of entry”
to a building (including house or office other premises), or within the building but other than at the “
point of use”
where the water exits the system to ambient pressure, the method comprising the steps of;
electrically producing oxidants which are mainly gases by passing molecules of air and/or water and/or water vapour through an oxidising chamber such as a corona discharge chamber; and
mixing these oxidants with the flow of water at an injection point, where the water at that injection point is at high pressure due to it being supplied through a pipe by a municipal water system, and where the injection point and the water pump are both located in the same by-pass loop, whereby the injection point delivers the oxidant at a constant rate irrespective of the variation of water pressure or water flow in the pipe either upstream or downstream of the water purifier.

Abstract
A system of purifying water in a pressurised system using a venturi to contact a chemical with the water, the system having a main water line from inlet (5) to faucet (15) and including a bypass loop (13) incorporating the venturi (6) to add the chemical to the water, a pump (12) in the bypass loop (13) to pass water through bypass loop (13) at constant pressure whereby the venturi (6) delivers the chemical at a constant rate irrespective of the variation of water pressure in the main water line (5) due to opening and closing of the faucet.
