Herco UO-D 3500 FU Filters

The reverse osmosis system is used for the desalination of softened water with a salt content of up to 1,000 mg/l. It is equipped with a high-quality centrifugal pump with frequency converter (FU). Frequency control reduces electricity costs by 30 - 50 %, extends the life of the system and keeps permeate production constant regardless of operating pressure. The RO digital microprocessor control enables fully automatic operation with logging of all relevant operating data and freely adjustable limit values. The system can be connected to the central control system via optional interfaces.

Advantages :

Equipping with FU saves 30 - 50 % on electricity costs, keeps permeate production constant and enables longer service life and particularly quiet operation
Versatile RO digital control with storage, operating data and many setting options
Optional equipment with PLC Siemens S7-1200

Conditions of use:

The plant may only be used for the desalination of softened feed water of drinking water quality or correspondingly pre-treated well or surface water. The plant is designed for a salt content (TDS) of 1,000 mg/l and a temperature of 15 °C. Under these conditions, the projected permeate output is also provided after three years of operation. The permeate yield depends on the raw water quality and the pre-treatment. The following parameters must be observed in the feed water:Free chlorine:undetectableIron (Fe):< 0.2 mg/lManganese (Mn):< 0.05 mg/lSilica (SiO2):< 25 mg/lBlockage index (SDI):< 3Feedwater temperature :5 – 35 °CSpee water pressure :2 – 6 barPressure fluctuation:± 0.5 bar
