Reverse Osmosis unit with a capacity of c. 2,000 l/day (c. 500 gpd)
The Merlin plus (PRF-RO) reverse osmosis unit operates using just the mains pressure of the tap water (3 - 4 bar), without the need for a high pressure pump. It has 2 high flow membranes and a combined activated carbon/sediment prefilter. Salt rejection is c. 90-95% and the recovery ratio (purewater:wastewater) is 1:3-4. The unit is frame mounted and ready to run. We recommend using an aquaniveau level control with an 1/2" M-ventil to give automatic control of the unit.
