Pretreatment of this machine has adopted stainless steel multi-medium filter, active carbon filter to remove large size impurities and floating materials effectively. Water input index of RO films is improved so that extraordinary smell and remaining chorine of the raw water can be effectively removed, and the taste quality of the water is therefore improved.

The main machine has applied high efficient low pressure compounded films from the USA, whose desalt rate of single film may reach up to 97%. Over high or over low-pressure protection facilities imported from South Korea have been applied to lower the problem rate of the facility to almost zero. High class standing type stainless pump from LOWALA, USA and medical material input system from Midunlo, USA have been applied.

The water supply standard fully complies with the national standard for pure water.
