A type of weak base anion resin for Hexavalent Chromium Removal from wastewater


Hexavalent chromium (Cr6+)is one of the chemical forms of chromium, which can be present in different forms in the environment,especially it will dissolve in water in the form of CrO4 2-.  Hexavalent chromium is very toxic, it may be a human carcinogen if ingested.

Usually there are certain methods for Hexavalent Chromium removal, like: electrodialysis,precipitation, active carbon adsorption, ion exchange etc. In which, ion exchange technology is considered as the more economic and highly efficient way for Cr6+ reduction. 

Sunresin produce a type of premium grade polystyrene macroporous, weak base anion resin MA940 which is highly selective to Hexavalent chromium.The resin is with higher working capacity for adsorption of Cr6+ from water and wastewater, like for Cr6+ removal from effluent in leather manufacturing, metal finishing,chromium plating etc.

The Seplite MA940 is very tipical anion resin which is with higher adsorption capacity, the outstanding performance on regeneration efficiency.With its strong matrix also ensures very good features for resistance of osmotic shock.After treated with MA940 resin, the Hexavalent chromium can be reduced to lower and safe level.

Selective resins for brine purification for ionic membrane caustic soda production

图片
SEPLITE LSC750 is a weak acid, macroporous, chelating resin with amino phosphonic acid groups. This structure is good for the chelating with heavymetal ions. Compared with the chelating resin with amino carboxylic acid groups, resins with amino phosphonic acid groups are much easier to chelate with certain cation ions. SEPLITE LSC750  is more suitable for removing of the heavy metals like Ca2+,Mg2+,Sr2+,Ba2+,Ni+ etc  thus to fully purify the second brine during production of membrane caustic soda. For SEPLITE LSC750 resin,it enjoys the advantage of below: 1.Superior mechanical and excellent resistance to osmotic shock, good mechanical strength, 2.Low loss, lesstopping annually, stableKinetics performance 3.High chelating capacity,high chelating capacity leads to bigger amount of brine treated per cycle 4.More uniform for particle size,excellent running kinetics during regeneration Refer to Sunresin website for more information: http://en.sunresin.com/

Sunresin's ion exchange resins for starch base sweeteners purification

图片
The starch base sweeteners are produced from Wheat, Rice, Corn(Maize),Tapioca and etc. There are various types of starch sweeteners like: Glucose, Fructose, High fructose corn,syrupMaltose,Maltodextrin,Dextrose,and etc. The production of the starch sweeteners will need the Demineralization and Deashing which is the process of removing ash, protein and color and any other impurities from the solution. Seplite LSF970 series resins are sugar grade polystyrene ion exchange resins including cation and anion resin for starch sugar treatment, mainly for demineralization and decoloration of sugar syrup.The resin can totally replace active carbon for decoloration with higher efficiency, more clean process and more economical effect. The resins are approved by HALA certificate and widely used in starch sugar production. In starch sugar syrup filtration, LSF970 cation resin and LSF972 anion resin work together to remove salts, metal ions, organic, color,acids, and other impurities - resulting in

Sunresin's chelating ion exchange resin for Boron removal

Boron is the type of toxic element that come into water due to pesticide and fertilizer runoff, sewage spills, and coal production etc.  The EPA regulates the Boron concentration limit of 0.5mg/L as drinking water standard. Sunresin produces the chelating ion exchange resin LSC780 which is with the function group N-Methylglucamine and has the high  selectivity to Boron. SEPLITE LSC780 resin works with the excellent efficiency to remove Boron (borate) mainly from ground water, irrigation water and other high  Boron concentration brine. With its good kinetics and regeneration efficiency, the resin is very cost effective in the large scale operation. SEPLITE LSC780 resin is better to be applied in the solution of pH 7-14, After treated by resin, the Boron will be reduced to less than 1 ppm or even lower. The LSC780 resin will reduce boron concentrations mainly from below source of solutions:  1. Boron removal from municipal ground water  ----> effectively remove Boron to less
