WEIL - Low Pressure Reverse Osmosis System

Depending on the service, application, or location of the customer, various versions are offered:

• 100-300 l/h in a control cabinet or wall cabinet
• as an independent frame system with standing modules (100-1,200 l/h) or lying modules (1,500-9,000 l/h).
• as a small frame stand system (1,500-4,000 l/h with standing modules).
• in the glass-doored control cabinet (600–2,000 l/h).

The reverse osmosis systems are equipped as standard with:

• Special prefilter
• High-pressure stainless steel pump
• High-performance winding modules
• Float flowmeters for permeate and concentrate
• Pressure gauges for inlet pressure, pump pressure, operating pressure, and concentrate pressure
• Conductivity measurement in the permeate
• Automatic flushing solenoid valve

For convenient control and automation, a small PLC with a display is available for the smaller sizes, or a PLC control with a 4.3“ touch panel is available for the larger systems. The controller is equipped with extensive functions such as:

• Automatic start/stop via level sensors
• Flushing on demand (timer if system is turned off)
• Conductivity monitoring in the permeate
• Pump that can be adjusted for dry running protection

Among other things, the following functions can be optionally selected:

• Hardness control in the inlet
• Concentrate deficiency monitoring
• Permeate rejection or recycling
• Electronic flow and pressure measurement
• Anticalant dosing
