is it possible to run the waste water from an RO unit through a HMA unit to use it as part
of the tanks daily water changes

the reason being to cut down on waste water from the ro unit an ro unit produces
four gallons of waste water for every gallon of safe water to use in the tank so cutting down
or even removing the waste water from the equation altogether
When my mate produced RO for his marine setup, he piped the waste water (4mm pipe) out into the garden watering tubs of plants and flower beds. Had issues in the winter with outlet pipes freezing, but it felt better than just pouring the waste down the drain.
Generally a RO unit will produce 1:4 RO to waste if running at 8bar, which is why you use a pump. Average mains water pressure in UK is generally 3.5bar, so if you are using without a booster pump will be in the order of 1:10, even as far as 1:25 reported on these forums.the reason being to cut down on waste water from the ro unit an ro unit produces

No. There must be a pressure drop in order for force the water through the filter.biffster Member Offline Message Count: 278 New the HMA filter does not restrict the waste flow from the RO as HMA will operate under gravity feed
