Features

• 1. Effluent standard: Complies with the national standards for potable water.
• 2. High-pressure pump overpressure protection: When the outlet pressure of the high-pressure pump exceeds 6.5 MPa, the equipment automatically shuts down and triggers an audible and visual alarm.
• 3. Low-pressure protection for the high-pressure pump inlet: If insufficient feedwater causes the inlet pressure to drop below 0.05 MPa, the system will automatically shut down and activate an audible and visual alarm.
• 4. Equipped with a manual multi‑way valve, enabling convenient and rapid switching between filtration, backwashing, and forward flushing of the sand filter as needed.
• 5. The alarm system features manual acknowledgment and mute functions.
• 6. Includes a reverse osmosis membrane cleaning system, capable of performing physical cleaning, concentrate replacement, chemical cleaning, and protective solution injection for the RO membrane elements.
