Industrial Reverse Osmosis RO 300 RO 600 RO 900

Categories: ALL PRODUCTS, RO DEVICES

Devices for the desalination of softened drinking water according to the current European and world regulations for drinking water (without the presence of free chlorine) with reverse osmosis operation.

Device Design:

Support frame made of stainless steel, freestanding.

Special inlet filter with 5 μm filter cartridge, high-pressure, low-noise multistage centrifugal pump, low-energy reverse osmosis modules with energy efficient PA/PS composite membranes in GRP inner liner columns, NSF certified.

Stainless steel feedwater and permeate sampling valves, inlet solenoid / diaphragm valves and diaphragm flushing, needle control valves for adjusting permeate, concentrate and concentrate recirculation.

Pressure gauges for pre-filter inlet and outlet pressure, pump pressure, operating pressure and concentrate pressure, pressure switch for controlling feed water pressure and high-pressure pump. Permeate, concentrate and concentrate recirculation flowmeters, type: rotameter.

Controller for display of operating and control status, with LCD display 128 × 64 dot matrix with backlight.

Control functions: high and low level of feed water tank, low pressure of feed water alarm, high pressure alarm of high pressure pump, high and low level of permeate tank, conductivity measurement of feed water 0-4000 µS / cm, conductivity measurement of permeate 0-20μS / cm, 0-200 μS / cm (automatic selection) with automatic temperature compensation for reference temperature of 25 oC, display of desalination degree in% and water temperature.

RS485 separate interface, standard Modbus communication RTU protocol, baud rates 2400, 4800, 9600 adjustable via keyboard.

Control: inlet solenoid valve, low pressure pump, high pressure pump, solenoid valve for flushing membranes.

Conductivity electrodes of raw water and permeate of AISI 316 stainless steel and titanium.

The configuration and dimensions may vary depending on the specific requirements of the user.

The devices are designed for a maximum TDS content of 1,000 mg /l, a water temperature of 15 ° C, a maximum SDI index of 3 and free permeate output. Under these conditions, the devices will have a declared permeate flow over a period of minimum 3 years. The permeate utilization depends on the quality of the raw water and the type of pretreatment.
