Description

Reverse osmosis units for the desalination of hardness-stabilised water with a salinity of up to 1,000 mg/l. Operated with dosing of antiscale instead of upstream softening. Each unit is equipped with a high-quality centrifugal pump with variable-speed drive (VSD = FU), which reduces energy consumption by 30 - 50 % .

The RO digital microprocessor controller enables fully automatic operation with logging of all relevant operating data and freely adjustable limit values. The unit can be connected to the central control system via optional interfaces.

Advantages

Advantages of RO units with VSD (FU)



  • Energy saving of 30 - 50 % compared to RO units without VSD

  • Payback period for VSD usually less than one year

  • Permeate production constant independent of operating pressure (permeate constant control PKR)

  • Protection of the unit due to soft start

  • Particularly quiet operation
Footnotes

The RO devices are designed for a maximum TDS content of 1000 mg/l, water temperature of 15°c and maximum SDI of 3. The return will depend on the incoming water and the type of pretreatement.
