Ion exchange system is a kind of traditional water treatment technology which displaces all kinds of anion and cation in water by anion and cation exchange resin. The anion and cation exchange resins can be combined in different proportion to form cation exchange bed system, anion exchange bed system and mixed bed ion exchange system. The mixed bed ion exchange system is usually used to produce ultra pure water and high pure water after water treatment processes such as reverse osmosis. It is one of the irreplaceable means to prepare ultra pure water and high pure water.

Sunresin, began in 2015, Cooperate with enterprises in Yunnan Province that have obtained processing permission for cannabidiol (CBD).

Sunresin developed Seplite® LWT510 macroporous adsorption resin and Seplite® MA396 special resin for iron removal.

Sunresin adopts Seplite® XDA series high specific surface macroporous adsorption resin.

A polypeptide is a kind of compound that is made up of many amino acids connected by peptide bonds.

Today, with the advocacy of ecologically friendly and sustainable development of industry, many countries around the world have taken "green chemistry" as an important direction for the development of the chemical industry in the new century.

In the process of evaporation treatment of wastewater from by-product ammonium salt (including organic amine) of chemical industry, some ammonium salt will be hydrolyzed and converted into ammonia gas (or organic amine). They enter into the condensate with the evaporation and condensation of water vapor, resulting in the ammonia nitrogen in the condensate exceeding the standard (according to the evaporation process, the ammonia nitrogen content generally varies from 200-1000 mg/L), unable to be discharged or reused, which brings difficulties to the production enterprises, but also causes waste of resources.

The reasonable and effective treatment of waste water, waste gas and solid waste is the core of environmental protection work. With the in-depth development of national environmental protection work, the waste gas treatment work has gradually become the focus of environmental protection and attracted more and more attention, and the emission standard of volatile organic compounds in waste gas has become more and more strict. Volatile organic compounds (VOCs) are a kind of main air pollutants in the exhaust gas, mainly some low boiling point, volatile organic compounds, which are produced in the chemical production process of raw material reagents or solvents volatilization, which not only causes material loss to related production enterprises, but also brings difficulty to the treatment of exhaust gas.
