China Mixed Bed Polishing Ultra Purify Water Ion Exchange Resin Suppliers & Factory
Equipment overview
Mixed bed is short for mixed ion exchange column, is designed for ion exchange technology equipment. Is a certain proportion of positive and anion exchange resin mixed loading in the same exchange device, the ion in the fluid exchange, removal. Because the proportion of the positive resin is larger than the negative resin, so the negative resin in the mixed bed in the next positive resin. The loading ratio of prajnyang and Yin resin is 1:2, and the loading ratio is 1:1.5, which can be considered according to different resins. Mixed bed can also be divided into in vivo synchronous regeneration and in vitro regeneration mixed bed. The mainstream adopts synchronous regeneration type mixed bed, in the operation and the whole regeneration process are carried out in the mixed bed, regeneration resin does not move out of the equipment, and positive and negative resin regeneration at the same time, so the need for less auxiliary equipment, easy to operate. Mixed bed is mainly used to reduce the hardness, alkalinity and cation of water, so that it becomes softened water or deionized water.
Equipment features
The effluent quality is excellent, and the effluent pH value is close to neutral.
The effluent water quality is stable, and the change of short-term operating conditions (such as influent water quality or composition, operating velocity, etc.) has little influence on the effluent water quality of mixed bed.
The discontinuous operation has little influence on the effluent quality, and the time needed to restore the water quality before the shutdown is relatively short.
The recovery rate reached 100%
Scope of application
Mixed bed is generally placed in the electrodialysis or reverse osmosis device after (or directly applied to the water with lower salt content), further desalination of water can make higher pure water, widely used in electronics, chemical industry, medicine, atomic energy, electric power and other industries.
Frequently Asked Questions
Q: What is the purpose of a mixed bed ion exchange column?
A mixed bed is designed for ion exchange technology. It mixes positive (cation) and negative (anion) exchange resins in the same device to remove ions from fluids, reducing the hardness, alkalinity, and cation content to create softened or deionized water.
Q: What are the typical loading ratios for resins in a mixed bed?
The loading ratio of positive (cation) and negative (anion) resin is typically 1:2 or 1:1.5, which can be adjusted and considered based on the specific type of resins used.
Q: What is a synchronous regeneration mixed bed?
It is a mainstream mixed bed type where both operation and the entire regeneration process are carried out within the column itself. The resin does not need to be moved out of the equipment, and the positive and negative resins regenerate at the same time, requiring less auxiliary equipment and simplifying operations.
Q: How does discontinuous operation affect the effluent quality?
Discontinuous operation has very little influence on the effluent quality of a mixed bed. Additionally, the time required to restore the original water quality after a shutdown is relatively short.
Q: Where is the mixed bed system typically positioned in water treatment?
It is generally placed after electrodialysis or reverse osmosis systems (or directly used with water of lower salt content) to further desalinate water and produce high-purity water for industries like electronics, chemical, medicine, atomic energy, and power.
