Elite Plus 3500ND - 16500ND series water purufication - PURITE - #2

FIRST FOR PURE WATER

Operating data: permeate conductivity (temperature corrected), permeate temperature, operating hours, feed water conductivity, percentage salt rejection.

Alarm signals: low pressure, hard water, motor overload, high conductivity pre-alarm, high conductivity fault, concentrate fault. Status signals: permeate discard, permeate recycling, concentrate displacement, concentrate rinse, intermittent rinse during shut­down, shut-down by external signal (forced stop, regeneration). LEDs for operation, alarms, regeneration, discard, disinfection, full tank, rinse.

Input (low voltage) for level control with 1 or 2 float switches, hardness monitoring unit. The Puritron 2000 control system includes control functions for the hardness monitoring unit. Freely programmable universal input with LCD, additional conductivity measuring unit (e.g. for feedwater). Shut-downs by external signal (forced stop, regeneration).

Outputs for 2 solenoid valves for concentrate flushing, permeate discard and recycling, second high pressure pump, analogue signal (e.g. 4-20 mA) and DDC (freely programmable universal output with LCD, conductivity alarm contact and collective alarm signal, each on floating changeover contact).

ELITE^PLUS Reverse Osmosis Units 3500 ND - 16500 ND

Stainless steel base frame with plastic front panel to house the instruments and controls.

Special inlet filter, stainless steel, with 5 urn filter cartridge and 2 pressure gauges.

High pressure pump, low-noise, multi-stage centrifugal type. Low energy wound modules with energy saving PA/PS composite membranes in GRP pressure vessels with PP inliner. Valves and instruments including feedwater sampling valve, solenoid/diaphragm inlet valve, feedwater pressure switch, permeate, concentrate and concentrate recirculation flow meters, vibration-resistant pressure gauges for pump and concentrate pressure, stainless steel adjustment valves for permeate, concentrate and concentrate recirculation flow.

Puritron 2000 microprocessor control system for fully

automated monitoring and control of the reverse osmosis unit with LCD (16 characters per line).

The units are designed for a maximum TDS of 1000 mg/I, sized on a water temperature of 10 °C and a maximum colloidal index of 3. Under these conditions, the units still reach design permeate flow after three years of operation. With new units the working presssure is about 15% lower. The permeate recovery depends on the raw water quality and the type of pretreatment.

Errors and omissions excluded. Purite reserves the right to change specification without notice.
