1, automatic type is more convenient than semi-automatic type.

According to the different control valves, household water softener can be divided into automatic type and semi-automatic type. The automatic water softener needs electricity. Automatic water softener is divided into time type and flow type. Time type refers to the regeneration according to the set time, which will be automatically regenerated at that time. Flow pattern refers to regeneration according to the set water flow, and regeneration is carried out after regeneration. In addition, when the automatic controller water softener is regenerated, the amount of waste water and salt consumption is small, and it can be regenerated and softened at any time; Semi-automatic control valve consumes a lot of salt and wastewater.

The hardness of water treated by a good household water softener can be reduced to 17 mg/L, or even lower. The hardness of tap water is about 200 mg, 300 mg or 500 mg organic matter per liter of water.
