Aqualine BT-125-3 Reverse Osmosis Unit

Unit Design

• Stainless steel plate used as installation panel
• Special inlet filter with 5 µm activated carbon filter element, high pressure pump as peripheral impeller pump, high performance spirally wound module with PA/PS composite membranes in stainless steel pressure vessel.
• Inlet solenoid valve
• Pressure switch for pump feed pressure, pressure gauge for pump pressure
• Flow restrictor for limitation of permeate and concentrate flow rate
• Solenoid valve for automatic concentrate-rinse
• Connecting cable (2 m) with shockproof plug. Unit completely wired and pre-assembled and ready for installation. Electrical equipment in accordance with VDE 0100 part 600, VDE 0113 part 1
• RO 524 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, automatic restart of operation after progressive rest period
• LEDs for operation and disinfection status. Automatic con- centrate flushing after each operating cycle, forced flushing after 24 h standby
• Inputs (low voltage) for level control with 1 or 2 float switches, hardness monitoring unit limitron (the RO 524 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), for 2 solenoid valves and for DDC (collective malfunction signal on floating change-over 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 and 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
