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/

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/

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, ...

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...

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.

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/

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.

离子交换技术是利用离子交换剂中的可交换基团与溶液中各种离子间的离子交换能力的不同来进行分离的一种技术，是一种固液分离的方法。 离子交换是一种继传统分离方法如蒸馏、萃取、吸收等分离方法后，出现的一种化工分离技术。 离子交换过程是被提取或纯化的分子或离子，在水溶液中与固体交换剂之间发生的一种化学计量分配过程，这一过程既遵循固-液非均相扩散传质的普遍规律，但由于传统分离过程不同。 离子交换一般是指一种可逆的固一液化学反应，其中固体就是离子交换剂(树脂)。离子交换剂由惰性骨架(母体)、固定基团和活动离子（也可叫交换离子或反离子）三部分组成：如阳离子型离子交换剂R-SO3M，其中R为惰性骨架，SO3为固定基团，M为活动离子或可交换离子，SO3M为活性基团或功能基团。 离子交换技术的特点 1、离子交换操作属于液—固非均相扩散传质过程。所处理的溶液一般为水溶液，多相操作使分离变得容易。 2、离子交换可看作是溶液中的被分离组分与离子交换剂中可交换离子进行离子置换反应的过程。其选择性高，而且离子交换反应是定量进行的，即离子交换树脂吸附和释放的离子的物质的量相等。 3、离子交换剂在使用后，其性能逐渐消失，需用酸、碱再生而恢复使用。 4、离子交换技术具有较高的浓缩倍数，操作方便，效果突出。 离子交换技术的应用 离子交换可起到提取、分离、浓缩和精制的作用。 离子交换技术主要应用于水处理（水的软化、水的脱盐、冷凝水和超纯水的制备），生化提取（天然生物物质的分离回收、发酵产物的分离回收、制药工业的应用），三废处理（含放射性核素废水的处理、其他工业有害废水废气的处理），湿法冶金等。 应用领域：食品饮料、制药、表面处理、工业纯水、高纯水设备等水处理设备中。 Sunresin provides an extensive ion exchange resins serise, Contact us for details, sales@sunresin.com
