How An RO System Works
An RO system uses a series of filters
and treatments to change your water supply into an almost
pure water product.
The typical RO system is a
five-stage unit utilizing three stages of pretreatment (one
sediment and two carbon filtration) then a TFC membrane and
then the subsequent pure water and waste water are
routed to both the tank and traditional drain
connections.
The reason for the drain connections
is that some RO systems can produce 20 litres of waste
water, for every 1 litre of pure water that's produced.
This figure is being improved upon on an almost daily basis
and most RO systems now work on around 4 litres of waste
water for every litre of pure water that's produced.
If you need to produce 1000 litres of
pure water per day, then it's likely that you'll have to
find a way to dispose of the 4000 litres of waste water
that you'll also produce as a by-product.
This wastage results in millions of
litres of perfectly usable water being re-directed to
peoples drains every day of the year as this is the
quickest, easiest and cheapest way for people to dispose of
the waste water they've produced.
Zero Waste RO System
As a result of this huge waste,
there are several Zero Waste RO systems that have
already been developed and these use various ways of
re-routing your waste water back into your main water
supply which is then passed through your RO system again,
resulting in the production of your pure water with
absolutely no waste water at all being dumped into your
drains.
