General information on reverse osmosis
2. General information on reverse osmosis
The reverse osmosis process is an eco-friendly, physical technology for desalination
of drinking water without chemicals, for the purpose of generating pure water for
industry and cleaning.
The advantages of the reverse osmosis process compared to other desalination
methods are substantial:
•
Maximum removal of all dissolved and dispersed water constituents (anions and cations
of salts, airborne particles, colloids, bacteria, etc.).
•
Low operating costs, high use-value, quick amortisation.
•
Minimal pre-treatment.
•
Continuous operation.
•
Small space requirement.
•
High pure water quality.
•
User-friendly and eco-friendly method, requiring no regeneration of the
•
membrane since no acids or bases are used as in chemical desalination.
Important information
To prevent damages to the system and modules, please thoroughly read and
observe the operating instructions prior to installation and start-up!
ATTENTION!
The fed water must be in compliance with the German Drinking Water Regulation. It
must be completely free of iron-manganese heavy metals (max. 0.05 mg/l manganese,
max. 0.2 ml/l iron); the maximum silicate (SiO2) content may not exceed 20 mg/l. In
addition, the feed water must not contain any barium and strontium. If the water
contains chlorine, an additional activated charcoal pre-filter must be used (at RO30G).
The models RO30C and RO60S are already equipped with a carbon pre-filter.
It is essential to also observe the following:
•
The system must be connected to a cold water supply. The water temperature
shall be max. 25°C.
•
In case of an interrupted raw water supply or power supply of more than 1 week,
the system must be preserved according to the preservation regulations. Another
possibility is to operate the system at least every 7 days for approx. 5 minutes.
•
Preservation, see also item 7.
•
Please make sure filters are replaced on a regular basis (both pre-filters, as well as
any applied activated carbon filter).
