• The Dual Tank Dual Valve Water Softening System is an automated water treatment system for continuous water supply scenarios. The system consists of two resin tanks and two sets of control valves, each operating independently and backing each other up, thus ensuring that the soft water supply is not interrupted at any time.
• The system design emphasizes high efficiency, stability and intelligent control, and is particularly suitable for industrial users under continuous operation conditions day and night.

Structure and Working Principle

• The system structure includes two pressure vessels (filled with cation exchange resin), two sets of automatic control valves, two salt tanks and the corresponding piping system.
• Each tank can independently complete the operation of water inlet, outlet and regeneration. During the operation of the system, one tank is responsible for water discharge and the other is in standby or regeneration state.
• When the running tank reaches the set exchange capacity or running time, the system automatically switches to another tank through the controller, and the original tank enters into the regeneration process without human intervention and without affecting the normal water supply.

Main Technical Parameters

• Water flow range: 1~10m³/h per tank;
• Resin loading capacity: depending on the demand configuration, commonly 50~200 liters;
• Working pressure: 0.2~0.6 MPa;
• Control mode: flow type, time type, dual control optional;
• Water hardness control: usually can be reduced to below 0.03 mmol/L;
• Regeneration mode: downstream or countercurrent regeneration can be customized, depending on the site requirements configuration.

System Features

• Strong continuous water supply capacity: Since the two tanks can work in rotation, even if one of the tanks is regenerating, the other tank can continue to produce soft water to meet the requirements of uninterrupted operation.
• Intelligent control system: the controller automatically records the operation status and judges when to switch and regenerate according to the set parameters, which improves the operation efficiency.
• Energy-saving and salt-saving design: Compared with the manual control system, the system utilizes the resin exchange capacity more efficiently and reduces salt consumption and wastewater.
• Easy maintenance: Each component operates independently, system maintenance does not affect the overall workflow, and operators can easily complete daily inspection and maintenance.
