In the chlor-alkali industry, the use of ion-exchange membrane electrolyzers to produce sodium hydroxide has become a common practice. However, this membrane method requires that the content of calcium and magnesium ions in the brine into the tank be less than 20ppb. The old refining method can only reduce the content of calcium and magnesium ions in the brine to about 1 ppm.

Sunresin's professional and clean packaging has been recognized by customers both in China and around the world.

In nature, substances appear in the form of mixtures. This rule applies to our most common, simple, and indispensable sunlight, air, and water. The sunlight splits into seven colors namely violet, indigo, blue, green, yellow, orange, and red. Air is mainly composed of nitrogen, oxygen, argon, carbon dioxide and some other substances. The water we consume in our life also dissolves many ions such as calcium, magnesium, sodium, potassium, carbonate, bicarbonate, sulfate, and chloride ions.

As the world transitions to “Green Energy”, Lithium has become one of the most sought-after metals in battery production which empowers industries such as Electrical Vehicles. Sunresin’s adsorption technology (adsorbents, Simulated Moving Bed equipment and industrial process) have been widely and successfully used in a number of Lithium Extraction projects.

This is a set of dichloroethane treatment equipment, which helps to recover 2.16 tons of dichloroethane per day while meeting the emission requirements. This is a set of dichloroethane treatment equipment, which helps to recover 2.16 tons of dichloroethane per day while meeting the emission requirements. This translates to a payback period of about one year.

Welcome to Sunresin's first Livestreaming event during the Aquatech China trade show. In this video, you will find the following information regarding company's introduction and product specifications in water treatment.

As an innovation-driven, high-tech company from Xi’an, northwest China, Sunresin specializes in adsorption and separation technology by supplying Ion exchange resins, adsorbent and chelating resins, equipment solutions as well as relevant technical services.

Sunresin is proud to offer a new generation of Nickel-selective chelating resins to overcome the disadvantages of solvent extraction methods: Seplite® LSC495 offers high selectivity for Nickel and is unaffected by Iron in solution. Consequently, no pretreatment is necessary, which makes it possible to reduce the losses of nickel. Regeneration of Seplite® LSC495 can be carried out by sulfuric acid and does not lead to saponification of the bis-Picolylamine chelating group. Thanks to its very high selectivity, this type of resin has made it possible to considerably reduce the cost of nickel production.
