herco rs & rse range ro water filters

Unit design

Reverse Osmosis Water Filter. Stainless steel base frame with plastic front panel housing the instruments and controls. Special inlet filter 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 feedwater sampling valve, solenoid inlet valve, feedwater 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 meters) with 16 A – 6 h CEE three-pole plug. Unit completely wired and pre-assembled and ready for installation. Electrical equipment in accordance with VDE 0100 part 600, VED 113 part 1.

RO 1000 Controller

RO 1000 microprocessor control system for fully automated monitoring and control of the system with two line text display (16 characters per line) for visualisation of RO process and display of operational status: permeate conductivity (temperature compensated), permeate temperature, operating hours, Status signals: permeate reject, permeate recycling, concentrate displacement, concentrate rinse, intermittent rinse during shut-down, shut-down by external signal, LEDs for production, fault, disinfection, reject, external stop and tank full. Inputs (low voltage) for level control with 1 or 2 float switches, hardness monitoring unit (the RO 1000 control system includes control functions for the limitron hardness monitoring unit), shut-down by external signal, 2 universal inputs. Outputs for softener (230 V/50 Hz), 2 solenoid valves for concentrate rinse, permeate reject and -recycling, universal output, analogue output (4-20 mA) for permeate conductivity and DDC (collective malfunction signal on volt-free changeover contact).

The unit is designed for a maximum TDS of 1,000 mg/l, a water temperature of 15°C, a max. colloidal index of 3 an free permeate outlet. Under these conditions, the unit still reaches design permeate flow after 3 years of operation. The permeate recovery depends on the raw water quality and the type of pre-treatment.

RO 500 Controller

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 (230 V / 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 max. colloidal index of 3 an free permeate outlet. Under these conditions, the units still reach design permeate flow after 3 years of operation. The permeate recovery depends on the raw water quality and the type of pre-treatment.
