EDI纯水设备系统，作为水处理领域的先进技术，以其独特的工艺流程和高效的去离子能力，在工业生产中占据了重要地位。与传统混合离子交换技术相比，EDI纯水设备在出水稳定性、自动控制易行性、运行可靠性以及化学再生不需等方面具有明显优势。此外，它还能降低运营成本，并且因设计紧凑而不占用大量厂房空间，同时无污染排放。
ED pure water equipment system is a cutting-edge technology in the field of water treatment, known for its unique process flow and high efficiency in removing ions. Compared to traditional mixed-bed ion exchange technology, EDI pure water equipment excels in terms of output stability, ease of automation control, reliability during operation, and the elimination of the need for chemical regeneration. Moreover, it can reduce operating costs and does not occupy large spaces due to its compact design while producing no pollution.
The development history of high-purity water device technology can be broadly divided into three stages: pre-treatment followed by active beds (sun beds), passive beds (shade beds), and mixed beds; pre-treatment followed by reverse osmosis (RO) and then mixed beds; and finally pre-treatment followed by RO coupled with ED devices.
Reverse osmosis systems are able to remove 95-98% of ions from water but cannot fully meet industrial production requirements. Thus subsequent processes must employ ion exchange devices. The use of ion exchange as a standard method for purifying water has been prevalent over recent decades but now faces challenges due to periodic regeneration needs accompanied by significant consumption of chemicals such as acid-base substances or purified water itself.
To address these limitations, the integration technology combining membranes with resins emerged as an innovative solution – namely Electrodeionization (EDI). This technique utilizes electro-regeneration instead of chemical reagents to replace conventional methods like mixing bed deionization that require regular cleaning cycles using substantial amounts of chemicals along with purified water.
In summary:
Water enters the EDI system primarily flowing through resin/membrane interiors while another portion flows outside them for washing away external membrane-ion combinations.
Resin within EDI captures dissolved ions present in feedwater.
Ions trapped within resin move towards electrodes under electrical influence – positive ones toward anodes while negative ones toward cathodes.
Positive ions pass through cationic membranes outwards from resin/membrane areas.
Negative ions similarly pass through anionic membranes outwards from resin/membrane areas too.
6.Dissolved salts concentrate on waste liquid streams which are removed after passing through used-up regions inside resins/membranes
7.Final distilled product emerges from interior reservoirs without any traceable impurities
Thus this advanced purification method significantly reduces dependence on traditional techniques reliant on manual intervention or continuous replenishment processes involving harmful chemicals resulting ultimately leading towards sustainable solutions catering future demands more efficiently than ever before since inception time!
