Product Description
The ready-to-connect combi unit includes a pre-filter, a backflow preventer, a duplex water softener, a limitron hardness control device and a counterpressure reverse osmosis unit. It is used for the desalination of water with a salinity of up to 1,000 mg/l . It is designed for a permeate counterpressure of 4 bars and can be operated with up to 7 bars. The unit is equipped with a compact rotary vane pump (unit size 50 and 150) or a high-quality centrifugal pump (unit size 300 - 1,200) as well as a full-flow diaphragm pressure vessel. The microprocessor controller RO digital enables fully automatic operation with logging of all relevant operating data and freely adjustable limit values.
Benefits
Ready-to-connect unit including pre-treatment
Simple installation on site with only four connection points (drinking water, permeate, waste water, socket)
Design with minimal dead zones and hygienic operation to meet the requirements of air conditioning applications
Transport of permeate over several floors possible, no permeate storage required
Versatile RO digital controller with logging of operation data and many parametrisation options
Applications
Continuous water softening and desalination
For the direct supply of e.g. air-conditioning systems such as humidifiers with water according to VDI 6022
Controller :RO digital
Desalination rate min.:97 %
Permeate recovery:75 80 %
Permeate back pressure max.:4 - 7 bar
pH value operation:3.6 9.5
pH value cleaning:2 12
Ambient temperature:5 40 °C
Conditions of use: The unit may only be used for the desalination of feed water with drinking water quality or appropriately pre-treated well or surface water. The unit is designed for a salinity (TDS) of 1,000 mg/l and a temperature of 15 °C. Under these conditions, the projected permeate output is achieved even after three years of operation. The permeate yield depends on the raw water quality and the pre-treatment. The following parameters must be maintained in the feed water:
Free chlorine:not detectable
Iron (Fe):< 0.2 mg/l
Manganese (Mn):< 0.05 mg/l
Silica (SiO2):< 25 mg/l
Silt density index (SDI):< 3
Feed water temperature:5 35 °C
Feed water pressure:4 6 bar
Pressure fluctuation:± 0.5 bar
