Already available in Alchimia, this replacement kit includes a reverse-osmosis membrane and a 1:1.5 restrictor, compatible with the GrowMax PowerGrow system. Is produces 500l of pure, clean water per day.
The 1:1.5 restrictor reduces the waste of water, since with it we only need a little more than two liters of tap water to produce one liter of clean water (normally, we would have needed 3 liters of tap water to produce one liter of clean water, 1:2).
If the inlet pressure is 4-6 bars the ratio will be 1:1. If the water is hardness is high, it will calcify the osmosis membrane and more water will be wasted.
On the other hand, the membrane works more so it will have to be replaced a little earlier.
