ED pure water device system, through the precise electrochemical regeneration technology, fills up the shortcomings of traditional mixed-bed ion exchange technology (MB-DI) and realizes stable high-purity deionized water production. Compared to mixed-bed ion exchange technology, ED pure water device system exhibits obvious advantages in the following aspects: ① The output deionized water quality is extremely stable; ② The operation mode is simple, conducive to fully automatic control; ③ Not limited by regeneration cycles, no need for shutdown maintenance; ④ Reduces dependence on chemical regeneration; ⑤ Lowers running costs and energy consumption; ⑥ Occupies less space, more suitable for modern industrial factory layout; and most importantly, it does not produce any pollutant emissions.
The development history of high-pure water equipment technology can be divided into three stages:
Stage One: Pre-treatment → Activated Carbon → Resin Bed
Stage Two: Pre-treatment → Reverse Osmosis → Resin Bed
Stage Three: Pre-treatment → Reverse Osmosis → ED Device
Pure Water Equipment Technology using Reverse Osmosis (RO) method has been a widely used technique that separates ions from water. Although RO systems remove approximately 95-98% of ions from the feedwater, they still cannot meet the requirements of industrial production. Therefore, subsequent processes must use ion exchange devices. In recent decades since RO systems have become common practice in producing high-purity water.
In addition to these methods mentioned above there are some new technologies like Electrodeionization (EDI), which is a membrane-based process that uses electrodes as an additional tool to improve its effectiveness over traditional techniques such as reverse osmosis or activated carbon filtration alone without needing chemicals at all during its operational cycle period due mainly because it works with just electricity instead!
