Usually the raw sugar syrup is yellow and dark colored, and before further crystallization to white sugar, it will always need the process of color removal. This used to require the active acrbon for decolorization, however,now there is strong base anion resin which can replace caron for decolorization with higher  efficiency, better performance and can realize clean production, and also the resins can be regenerated for many times in operation, so using resins for decolorization is more cost effective.  SEPLITE ® LXA 958 is a highly cross-linked resin in the form of White-cream spheres. It is designed particularly for removing color substances from  highly colored liquid sugar solution. And certainly to be used for deionization of sugar solution together with LXA 983 that is SAC resin. Ion exchange method of decolorization has been proved to be more superior than activated carbon. With the Matrix of acrylic, SEPLITE ® LXA 958 provides wonderful adsorption and desorp...

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 wi...

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/

Ion exchange resins for heavy metals removal from electroplating wastewater  Wastewater from metal finishing or electroplating industries contains high concentrations of metals contaminants, like Nicke, Zinc, Chrome, Cooper and etc, these heavy metals are hazardous to the environment and human, thus it can not be discharged directly to the nature.  Sunresin produces a series of chelating ion exchange resins, which are with very good performance for metals removal from electroplating wastewater.  The main types are for: Nickle removal, Chrome removal, Cooper removal. With their special structure and high selective to the metals in certain condition, the resins are with very good effect for adsorption of the metal ions. With high regeneration efficiency and strong bead strength, the resins are with long lifespan in operation. 

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  ----> effective...

There are always heavy metals residuals like: Nickle, Cooper,Mercury, Chrome, Cadmium,Zinc etc in the acid rinse water from process of electroplating,  coating, metal finishing and etc. These metals are hazardous substances if discharged directly to the environment which will cause serious harm to human.

Lead is a naturally occurring toxic metal found in the Earth’s crust. Its widespread use has resulted in extensive environmental contamination,  human exposure and significant public health problems in many parts of the world. Lead can enter drinking water when service pipes that contain lead corrode,especially where the water has high acidity or low mineral content that corrodes pipes and fixtures.  Lead in drinking water is very harmful to human. In China, the government set 0.01mg/L as the minimum level of content for lead in drinking water. Sunresin produces a type of high quality lead selective ion excange resin for drinking water treatment.  The LSC755 resin is a weak acid, macroporous, chelating ion exchange resin with amino phosphonic acid groups.  This structure is good for the chelating with heavy metal ions, especially for lead removal from aqueous solution.  The resin has better adsorption rate for lead which works with bigger treatment capaci...

Demineralization is a process of removing mineral salt from water by using ion-exchange. The resulted water after the process will be free of dissolved minerals. Demineralization will involve Distillation, Deionization, Membrane Filtration or Electrodyalisis. Demineralized water with minerals removed is known as de-ionized water.  Deionization is a physical process that removes mineral ions such as cations of sodium, calcium, iron, copper, sulphate, nitrate, etc.  The process involves several steps which starts by flowing the raw water through two polystyrene bed with ion exchange resins.  The first polystyrene bed is used to exchange cations and hydrogen ions while the second one, hydroxyl ions and the anions are exchanged. Sunresin's premium grade mixed bed resin Seplite MB20 is very suitable for water demineralization. The resin is mixed with 40% cation and 60% anion resins and is used fo producing high purity water after RO for many industries like Water engine...

The EPA defines the Perchlorate as a contaminant in water. It is found that perchlorate may have an adverse effect on the health of persons and  is known to occur in public drinking water systems with a frequency and at levels that present a public health concern.  Sunresin produces a special type of selective ion exchange resin Seplite LSC106 for perchlorate removal, especially from drinking water. With its special matrix and tributylamine function group, the resin can realize high selectivity for perchlorate. In operation, Seplite LSC106 shows good mechanical strengh and excellent mechanical strength to osmotic and thermal shock. Since not easy handling the regeneration effluent, this resin is not suggested to be regenerated for recycling use. For any interest, pls kindly refer to our website: http://en.sunresin.com/

The Environmental Protection Agency has set a maximum contaminant level of 10 mg/L for nitrate and nitrite in public water supplies. Nitrate in water is undetectable without testing because it is colorless, odorless, and tasteless. A water test for nitrate is highly recommended for  households with infants, pregnant women, nursing mothers, or elderly people. These groups are the most susceptible to nitrate or nitrite contamination. Sunresin produces the high quality LSC106 plus anion resin which is specially designed for Nitrate removal from water and any other aqueous solution. The resin with its triethylamine functional group is with high selectivity to NO3 in water.  The resin is with high capacity and physic stability, the special improvement on matrix makes it better resistant to pressures.
