Reverse Osmosis System

RO 200 (Item No.: 80545)

Product description

 
 
Reverse osmosis units create the optimal starting water for marine water and freshwater aquaria. Many water problems can often only be resolved by using reverse osmosis water. Reverse osmosis units use the principle of physical filtration. Unlike ion exchangers, for example, which exchange ions (e.g. calcium) which cause hard water with other ions (e.g. sodium) which do not cause hard water, reverse osmosis unit physically removes pollutants (e.g. silicate, nitrate) and hardness components from the water. In a reverse osmosis unit, the water runs through a semipermeable membrane at the residential pressure in water lines of 2 − max. 6 bar. The substances (pollutants, salts or hardness components) which have dissolved in the water are unable to pass the fine lattice structure of the membrane and remain in the residual water. This residual water is discharged as concentrate and can easily be used for cleaning, watering or as service water. Dupla reverse osmosis units retain up to 95 − 98 % of all pollutants in tap water.

Tip: By connecting a Dupla ultrapure water filter (optional) downstream, even the smallest particles of silicates and nitrates are fully removed.
