Dupla reverse osmosis 270 unit creates an ideal water source for seawater and freshwater aquariums.
Quite frequently many water problems can only be solved through the usage of osmosis water. the RO270 works by the principle of physical filtration. Other than for example ion exchangers that exchange hardness-causing ions (e.g. calcium) against non hardness-causing ions (e.g. sodium), the reverse osmosis draws pollutants (e.g. silicates and nitrates) and hardness-causing agents out of the water physically.
The water runs through a semi-permeable membrane with the pressure of 2-6 bar common for household water pipes. The substances dissolved in the water (pollutants, salts, or hardness-causing agents) cannot pass through the small grid structure of the membrane and remain in the rest water. This rest water is drained as concentrate and can be used as cleaning, watering, or domestic water.
The Dupla RO270 unit has a retention rate of 95-98 % of all pollutants in tap water.
Includes carbon filter, 5 μm fine filter, flow rate limiter and ¾ inch screw for water faucet connection with 6 mm pressure tube.
