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 KIVI special resin 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, KIVI special resin for perchlorate removal 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. Steven kivifilter@126.com https://kivifilter.en.made-in-china.com/

Anion ion exchange resins for Nitrate removal from water

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. KIVI WATER TECH produces the high quality special 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. contact us Steven kivifilter@126.com https://kivifilter.en.made-in-china.com/

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. KIVI premium grade mixed bed resin KIVI MBR20 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,

ion exchange resins special for Glucose, Fructose, High fructose corn,syrupMaltose,Maltodextrin,Dextrose

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. KIVI 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.

lead removal resin

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. KIVI produces a type of high quality lead selective ion excange resin for drinking water treatment. The lead removal 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 capacity and higher regeneration efficie

heavy 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. KIVI 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 lifetime in operation. Steven kivifilter@126.com https://kivifilter.en.made-in-china.com/

Brine softening resin

Brine softening resin 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. Brine softening resin 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 Brine softening resin 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 Steven kivifilter@126.com https://kivifilter.en.made-in-china.com/

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. sugar decolorization reisn is a highly cross-linked resin in the form of White-cream spheres.
