The softening resin tank is a tank used to remove hardness ions such as calcium and magnesium in water and soften the water. The most common is the glass fiber reinforced plastic softening resin tank, which is often used in water treatment occasions such as laundry rooms, hotels, chemicals, textiles and so on.

The control methods of the FRP softening resin tank are as follows: A. It consists of an ion exchange tank, a control valve and a salt tank. The regeneration control mode is divided into time type and flow type. During regeneration, water production needs to be stopped for 2 hours.

It is suitable for intermittent water supply occasions. If continuous water supply is required, a water tank can be configured to store water for 2 hours. B. Two ion exchange tanks are controlled by one control valve to supply water alternately and regenerate alternately to realize uninterrupted water supply. It is suitable for the occasion of continuous water supply. The regeneration method is flow type.

It consists of two control valves, two ion exchange tanks and a salt tank. The two sets of tanks are alternately supplied with water, alternately regenerated, and continuously supplied with water. The regeneration control mode is flow type.

It consists of two control valves, two ion exchange tanks, and two salt tanks. The two sets of tanks supply water at the same time, alternately regenerate, and continuously supply water. The regeneration control mode is flow type.

How to choose the appropriate control method for the FRP softening resin tank should be determined according to the actual processing capacity. If the processing capacity of the FRP softening resin tank is small, a single ion exchange tank and single valve control can be selected. If the processing capacity is large, multiple Ion exchange tank treatment.
