The water softener media resin regeneration method is divided into three types: forward flow, convection flow and shunt flow according to the regeneration liquid flow direction and the water flow direction during operation.

Downstream regeneration refers to the regeneration mode where the regeneration liquid flows in the same direction as the water flow during operation, and usually flows from top to bottom.

Convection regeneration means that the direction of regeneration fluid is opposite to the direction of water flow during operation. Conventionally, the water treatment process in which the water flow flows downward during the operation and the regeneration liquid flows upward is called a countercurrent regeneration process. The water treatment process in which the water flows upward during operation and the bed floats; the water treatment process in which the regeneration liquid flows downward during regeneration is called a floating bed process. Convection regeneration can maximize the regeneration degree of the resin layer on the water outlet side, and the water quality is good.

Shunt regeneration means that the regeneration liquid enters from the upper and lower ends of the exchanger at the same time and is discharged by the drainage device in the middle of the resin layer. During operation, water flows from the top to the bottom. The upper bed of this exchanger adopts the co-current regeneration process, and the lower bed adopts the convection regeneration process.
