China Mixed Bed Polishing Ultra Pure Water Systems from Top Suppliers and 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 a mixed bed ion exchange column?
A mixed bed is an ion exchange equipment where a specific proportion of positive (cation) and anion exchange resins are mixed and loaded into the same exchange device to remove ions from the fluid, producing highly purified water.
Q:
What is the typical resin loading ratio in a mixed bed?
The typical loading ratio of cation to anion resin is 1:2 or 1:1.5. This ratio can be adjusted and optimized based on the characteristics of different resins and water treatment requirements.
Q:
How does a synchronous regeneration mixed bed operate?
In a synchronous regeneration mixed bed, both the operation and the entire regeneration process are carried out inside the vessel. The resins do not need to be moved out of the equipment, and both positive and negative resins are regenerated at the same time, simplifying operation and reducing auxiliary equipment needs.
Q:
What is the typical placement of a mixed bed in a water treatment system?
A mixed bed is generally positioned after electrodialysis (ED) or reverse osmosis (RO) systems, or applied directly to water with low salt content to perform further desalination and achieve high-purity water.
Q:
What industries benefit from using mixed bed technology?
Due to its ability to produce highly pure water, it is widely utilized in demanding sectors such as the electronics, chemical, medicine, atomic energy, and electric power industries.
