Adsorbent Resin

At present, adsorbent resin have been widely used in wastewater treatment, food analysis, chemical reagent purification, medical analysis and so on. Especially, some special high performance adsorbent resins can effectively treat wastewater and realize the reuse of wastewater.

We're pioneering the field of wastewater treatment with our state-of-the-art ion exchange method. This innovative approach is crucial in our Ammonia Nitrogen Removal Process, especially designed to effectively eliminate ammonia from evaporative condensate water, a common byproduct in evaporator units across various industries.

In the realm of industrial chemical processes, phenolic compounds are indispensable. They serve as foundational raw materials and intermediates in the production of a myriad of products, from dyes and pesticides to adhesives and photographic developers.

Since 2017, Sunresin has carried out research and development on BPA resins. From understanding the production process of bisphenol A to benchmarking against similar competition products, after thousands of experiments and demonstrations, the resins were be tested for the first time in 2022.

Sunresin’s VOCs treatment resin is a styrene-DVB matrix macroporous adsorption resin with a specially designed resin structure. It has a good mesh structure and a high specific surface area, and can be sieved through the size of the pores. Organic molecules are selectively adsorbed by interaction, intermolecular force or hydrogen bond interaction.

In Sunresin’s method, the hydrophobicity of the resin is further increased, the degree of crosslinking gets increased, and the pore structure gets adjusted. The adsorption resins have a narrow particle size distribution, uniform pore size and high specific surface area. As the size of micropores in the resin is close to the molecular size of perfluorooctanoate in water, which has a strong selectivity of the adsorbates and can therefore further increase the adsorption rate of perfluorinated compounds.

Sunresin is strongly supportive of the CO2 reduction as set in the Paris Climate Accord by enabling this growing Lithium demand for energy storage which will provide strong opportunities for its patented and proprietary equipment, solutions and services.
