What is water demineralization by Ion exchange?

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 engineering, EDM, Cleaning, Aquarium, Medical labs and etc.

A type of selective ion exchange resin for Lead removal

图片
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...

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/

Selective ion exchange resins for Perchlorate removal from water

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/
