Abstract

A drinking water vending dispenser for dispensing purified water comprising a coarse mechanical filter, an RO purification unit, an ozone purification unit, a UV purification unit, an active carbon filter, a chemical base purification unit and a fine mechanical filter.

Claims

1. A drinking water vending dispenser for dispensing purified water comprising a coarse mechanical filter, an RO purification unit, an ozone purification unit, a UV purification unit, an active carbon filter, a chemical base purification unit and a fine mechanical filter.

2. One or more aspects of the drinking water vending dispenser as in claim 1, substantially as described herein.

3. The drinking water vending dispenser for dispensing purified water machine as in claim 1 further comprising a tap water inlet and/or any type of water inlet, be it clean or contaminated

4. One or more aspects of the drinking water vending dispenser as in claim 3, substantially as described herein.

5. The drinking water vending dispenser for dispensing purified water machine as in claims 1 and 3 further comprising, a complete waste water recycling system in a drinking water vending dispenser machine. waste water in a drinking water vending machine could be a product of one or a combination of the following sources:

drain water as a result of the purification element of the system, water streaming out of a drinking water faucet, water streaming from the bottle disinfection procedure and drained, leaks within the tubing of the system and a result of system cleaning processes using back flush, to clean the filters and/or ion-exchange and adsorption system;

The drinking water vending dispenser for dispensing purified water machine as in claims 1, 3 and 5, further comprising a unique method to disinfect the drained water from the water faucet and from the bottle cleansing water stream. Water streaming from the faucet and bottle disinfection is exposed to external possible contamination hazards and so, need to be treated separately from the other drained water. Water streaming from the faucet and bottle disinfection flows directly to the vending machine purifying subsystem. In the purifying subsystem it flows through a RO and/or Ozone disinfection systems which are part of the purifying subsystem.

6. Back flush system with water enriched with ozone to better clean the filters and pipes of the vending machine

7. Elimination of possible infection of water stored in water tank by ozone injection and water circulation in predefined time intervals.

8. One or more aspects of the drinking water vending dispenser as in claim, substantially as described herein.

9. A drinking water vending dispenser system (hereinafter the “

system”

) that is designed to receive water from an external source, purify and disinfect the incoming water, and supply it to consumers on demand. The system includes the following components;

one or more sensors for the detection of contaminations;

initial filtering system;

initial water container;

ozone generator including reverse osmosis filtering system;

ozone storage container;

water treatment container;

waste water collection container;

drinking water outlet;

orifice/sprayer for rinsing bottles;

control unit;

pumps;

valves; and

piping between the internal subsystems;

Whereby the sensors test and check the water quality and input the obtained information to the control unit, which determines the intensity of treatment the water requires according to its real-time quality;

Whereby the incoming water flows into the initial container and from there is pumped to a reverse osmosis filtering system, and then to the ozone generator where ozone is generated and stored in the ozone container; and

whereby the water discharged during the ozone generation process is recirculated back into the initial water container for reuse.

Whereby a pump, which is connected to the ozone container, pumps the water from the initial container to the treatment container and in the process also enriches the water with ozone;

Whereby the water flows on demand from the treatment container to the system'"'"'s outlet through a secondary filtering system whose function is to remove remaining ozone from the water that is to be consumed;

Whereby the system enables to rinse, clean and disinfect external bottles by rinsing them once or more with ozone-enriched water and collecting the run-off rinsing water into a rinse water container;

Whereby the system enables to circulate the water in the rinse water container;

Whereby the system enables to circulate the water in the treatment container and enrich it with ozone;

Whereby the system enables to circulate the water in order to rinse and disinfect the secondary filtering system;

And whereby the system enables to clean and disinfect the water piping and outlets
