The RO50PP comes complete with a CP tap, drain connector, 16 litre storage vessel, all the necessary tubes & fittings plus complete instructions. The RO50PP is the complete simple, economical answer to your families needs for the purest water available for drinking & cooking.
The purification process starts with a 5 micron pre-filter to remove & reduce large particles. Then the second stage of carbon filtration:- Block removing chlorine's, pesticides, VOC's, THM's, and smaller particulates. The TFC membrane then separates out the remaining contamination in the water and this is passed to the drain, while the pure water is stored for use in the 16 litre storage vessel. When you require water the water in the 16 litre storage vessel is immediately available for use. It passes through the fourth stage filter just before its dispensed via the tap.
To prevent waste the RO is equipped with a "auto shut-off" valve. Sensing when the 16 litre storage vessel is full it shuts down the system preventing un-necessary water going to waste. The moment you open the tap it will re-activate the system to start producing water again, until the 16 litre storage vessel is once again full. To aid production the Permeate Pump takes the energy in the drain line and uses it to add pressure to the feed line.
Reverse Osmosis needs decent water pressure (above 35psi) to make it work at an acceptable level of performance. If you pressure is low then choose a system with a pump. Its also a slow process this is why there is a need for a storage vessel with most systems.
Reverse Osmosis Systems waste a certain amount of water. The contaminants, along with waste water are passed to the drain when the unit is running. However this is far greener solution than the cost & waste in producing bottled water, puting it in plastic containers, transporting it and disposing of the waste, not to mention the actually going to the shops to buy it.
