herco rs & rse range ro water filters

Description

Stainless steel base frame with plastic front panel housing the instruments and controls. Prefilter with 100 μm-filter cartridge and 2 pressure gauges, pipe separator (EA1) according to DIN 1988 part 4, softener, compact design, hardness monitoring unit limitron for continuously monitoring of feed water hardness, in case of hard water the reverse osmosis shuts-down, special inlet filter, polypropylene with 5 μm- filter cartridge and 2 pressure gauges, high pressure pump, rotary-vane type, high performance wound module with PA/PS composite membranes in GRP pressure vessel with inliner. Valves and instruments including feed water sampling valve, solenoid inlet valve, feed water pressure switch, permeate and concentrate flow meter, vibration-resistant pressure gauges for pump and concentrate pressure, stainless steel valves for adjustment of permeate and concentrate flow rate and concentrate recirculation. Microprocessor control system, as described below, connecting cable (3 m) with 16A – 6h CEE three-pole plug. Unit completely wired and pre-assembled and ready for installation. Electrical equipment in accordance with VDE 0100 part 600, VDE 113 part 1.

RO 500 microprocessor control system

For fully automated monitoring and control of the reverse osmosis unit with two-digit alphanumeric display of permeate conductivity, forced stop and full tank, malfunction signals: low pressure, hard water and high conductivity, LEDs for operation and disinfection, inputs (low voltage) for level control with 1 or 2 float switches, hardness monitoring unit (the RO 500 controller includes control functions for the limitron hardness monitoring unit), shut downs by external signal (forced stop, regeneration), outputs for softening unit (230V/50 Hz) and DDC (collective malfunction signal on floating changeover contact). The units are designed for a maximum TDS of 1,000 mg/l, a water temperature of 15°C, a maximum colloidal index of 3 and free permeate outlet. Under these conditions, the units sill reach design permeate flow after three years of operation. With new units the working pressure is about 15 % lower. The permeate recovery depends on the raw water quality and the type of pre-treatment.
