Overview

Large pore cation exchange resin boiler water softener resin manufacturer directly supplies $r $n. First, use saturated saline solution, which is about twice the volume of the treated resin. Soak the resin in the saline solution for 18-20 hours, then drain the saline solution and rinse with clean water to make the discharged water not yellow; Next, use a 2% -4% NaOH solution with the same amount as above, soak in it for 2-4 hours (or clean with a small flow rate), drain the alkaline solution, and rinse the resin until the discharged water is close to neutral; After $r $n, use 5% HCl solution with the same amount as above, soak for 4-8 hours, drain the acid solution, and drift to the middle with clean water

1、 Transportation and storage of resin:

Ion exchange resin contains a certain amount of moisture, which should be maintained as much as possible during transportation and storage. If the resin loses water during storage, it should be soaked in concentrated saline water (8-10%) for 1-2 hours before gradually diluting. It should not be directly placed in water to avoid rapid expansion and breakage of the resin. During storage or transportation, the resin should be kept in a temperature environment of 5-40 ℃ to avoid overcooling or overheating, which may affect its quality. If there is no insulation equipment in winter, the resin can be stored in saline solution, and the temperature of the saline solution can be determined according to the temperature.

2、 Pre treatment of new resin:

New resins often contain solvents, substances that have not participated in polymerization reactions, and small amounts of low polymers, and may also adsorb heavy metal ions such as iron, aluminum, and copper. When the resin comes into contact with water, acid, alkali, or other solutions, the soluble impurities mentioned above will be transferred into the solution, contaminating the effluent quality in the early stages of use. So, the new resin needs to be pre treated before being put into operation.

2、 Application scope of Jinda softened water resin C100E
Jinda Softened Water Resin C100E is also used in the preparation of softened water, desalinated water, pure water and high-purity water, sewage treatment, monosodium glutamate manufacturing, pharmaceutical purification, chemical catalysis, rare metal separation and other fields.
Jinda Softened Water Resin
Jinda Softening Water Resin C100E uses ion exchange technology to reduce the hardness of water to less than 50mg/L (CaCO3). Ion exchange is a special dynamic adsorption process, usually carried out by insoluble ion exchangers in electrolyte solutions, which are called ion exchange resins. At present, more than half of ion exchange devices are used for water treatment desalination, and the main types of water treatment desalination are Jinda strong acid resin and Jinda weak alkali resin.

The present invention discloses a rapid cultivation method for anaerobic ammonia oxidation activity of sludge based on cation anion resin adsorption of nutrient matrix. Under anaerobic conditions, sludge with or potentially with anaerobic ammonia oxidation activity is mixed with anion and cation resins and placed in a reactor. A certain concentration of culture medium is added, and cultivation and production are carried out under suitable conditions for anaerobic ammonia oxidation bacteria. Cationic and cationic resins adsorb ammonia nitrogen and nitrite nitrogen, tightly binding with anaerobic ammonia oxidizing bacteria to ensure sufficient nutrients in the surrounding environment of anaerobic ammonia oxidizing bacteria. Advantages of the present invention: 1) easy cultivation of a large number of anaerobic ammonia oxidizing bacteria; 2) The cultivation method used is simple.
