If the water is contaminated by chemical/industrial/mining/septic/sewer spills.  Flood water in urban areas.

When the water is clear and you want to make sure it is cleaned of chemicals and pathogens.  

When the water needs to be cleaned up “a lot”.

When you want to get rid of the natural colour, eg tannins, in the water.

 

Do these Purifiers do away with the need for filters?

Mechanical filters, yes!  Activated carbon filters, no!  If the water needs a Purifier to clean it, a mechanical filter would be of no use.  Our Purifiers do not always remove all the molecules associated with a bad taste or odour.  Passing the water through an activated carbon filter would remove any residual odour or taste in the water.  However with our Purifiers removing about 95% of those molecules, your carbon filter will last much longer.

 

The Purifier has three separate functions, treating the water to remove the chemicals, cleaning the water and disinfecting the water.   You can leave these functions set to maximum time and it will do a good job every time.  However it will also use the plates and battery much more rapidly than is needed.  To get the correct time, follow the easy instructions provided in the manual.  Setting different times is equivalent to  deciding which filter you should choose for your situation.  If you choose the wrong filter, it is a long way back to the shop for the right one.  With the Purifier, it takes only a few minutes to make the adjustment to get the equivalent of a new filter, one that will give you just what you want.

 

The Purifier first discolours the water while it is removing the chemicals.  If the water does not discolour, not all the chemicals have been adequately treated.  You will have to adjust the TREAT control for greater treatment.  Once the water is discoloured, the purifier will then clean the water and it will go clear.  At this stage, chemical removal is as complete as it will be.  

 

How does the Purifier disinfect the water?

Primarily by removing the pathogens – typically about 99% of them go this way.  In its disinfection process – its final stage – the Purifier interrupts most pathogen’s cell motility and efficacy processes, killing them.  The longer the water stands after treatment (up to 12 hours), the higher the pathogen destruction rate.

 

The following tests were performed and tested at a NATA registered laboratory.  They give some indication of the capabilities of the Purifier technology.  

 

 

 

 

To illustrate the power of the Purifier, a sample of clay water with 20% raw septic tank water infusion was prepared, see A below.  This represents “seriously” polluted floodwater   It was treated by a Purifier, with the water quality shown in B being produced after a few hours standing.  This treated water has a slightly greater turbidity than city tap water (sample C) and a small residual septic odour, although the tested E-coli count was < 1 per 100 mL.  The water quality in D was produced after the treated water was passed through an activated carbon filter.  It was at least as clear as the city tap water and had no detectable odour.  

 

 

The water in A was passed through a quality hand operated filter.  It produced water of a similar quality to D, but clogged before it could produce 1 litre.  Even a personal Purifier could treat several thousand litres of A to B, with a turbidity of less than 5 NTU and zero E-coli count.
