Sunresin's ion exchange technology for lithium extraction from brine

图片
Recently, Sunresin company and Shaanxi Membrane Separation Technology Institute made the mutual investment agreement to set up the new company that will specialize in R&D, manufacturing and sales of ion exchange resins and membrane for lithium extraction from brine in salt lake. The two companies will fully cooperate and take both technical advantages to form the core technology for lithium extraction. 

The new joint company will be the leading and comprehensive platform for lithium extraction from brine. Now the pilot project of  lithium carbonate extraction in Cold Lake,Qinghai province of China has been put into regular operation, the high purity lithium carbonate has been successfully extracted already. This marks Sunresin company has taken the important step of industrialization the core technology of its ion exchange resins and related separation equipment system for lithium extraction.

Metals Extraction by IX technology is the important strategic sector of Sunresin business, …

A type of Acrylic strong base anion resin for cane sugar decolorization

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 desorption performance for lar…

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 effici…

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

Sunresin's ion exchange resins for metals removal from electroplating wastewater

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. 

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 than 0.5ppm 

2. B…

Chelating resin for Electroplating Wastewater Treatment

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.

There are usually a series of technologies that can remove the metals from waste stream, Ion exchange(IX) is proven to be the very cost-effective technology for removing the metal ionic contaminants from industrial wastewater, especially for Electroplating Wastewater.

Sunresin produces a series of premium grade selective ion exhcange resin which is specially used for removing heavy metals such as Nickle, Cooper,Mercury, Chrome,Zinc etc from industrial wastewater, The resins are with very good selectivity to the metals and with higher working capacity during the treatment. By resins treatment, the target
metals content in the wastewater can be highly reduced to under limit level so as to me…
