UO-D 25000 AS/FU
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.
