An RO (reverse osmosis) 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 pre-treatment
(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.
A zero waste RO system is certainly
worth considering if the water you are using is coming into
your premises through a water meter. By cutting the amount
of water used to produce your pure water, from 4 litres per
litre to 1 litre per litre, your pure water will be
costing you a quarter of what it is currently costing you
to produce.
Have a look at how much your water
company is charging you for your water, and you'll see how
much a zero waste RO system will save you each and every
month on your water bill.
If you do use a water meter, how many
months will it take you to recover the initial outlay for
your zero waste RO system through using less tap water to
produce each litre of pure water? Also, think what you'll
be doing to help the environment and to reduce the size of
your carbon footprint.
