Structural form: modular design, compact structure, beautiful layout and convenient operation and maintenance;
The pretreatment double softener can realize series operation and alternate regeneration by using the valve group. Each softener has 100% water supply capacity. The whole process of softener operation, backwashing, salt absorption, regeneration, forward washing, etc. adopts full-automatic programmed control;
Both the raw water pump and the first and second stage high-pressure pumps adopt frequency conversion control, which can not only realize different pressure control of the filter and softener under various operating conditions, but also realize low-speed and small circulation of the produced water during the standby mode of the system, greatly reducing the probability of microbial breeding and effectively saving energy;
The system terminal adopts the mode of two-way water supply and one-way circulation, that is, when the produced water is qualified, the product enters the purified water tank through two pipelines, and when the produced water is unqualified, it flows back to the middle water tank after being circulated through two pipelines. When the purified water tank is full, it will automatically switch to the circulation pipeline to effectively avoid the existence of empty pipes and ensure that there is no dead water
The purified water produced meets the specifications of purified water in Chinese Pharmacopoeia (CP2020), United States Pharmacopoeia (USP43) and European Pharmacopoeia (EP10).
