SUZHOU X CHEMICAL CO.,LIMITED

Suzhou X Chemical offers a wide product line of cation exchange resins for domestic and industrial water softeningincluding fine mesh resins, highly crosslinked resins, coarse mesh resins, low crosslinked resins andmacroporous resins. In general, softening is the removal of Calcium and Magnesium to prevent hardwater from scaling on piping, plumbing fixtures, bathroom surfaces and etc. It is also called the removalof hardness.XResin's softening Resins are used to soften water for use in appliances such as washing machines,dishwashers and steam irons. They are also used in filter cartridges for purification of drinking water,used in laundries, in brewing and soft drink manufacture for bottle washing, process water for boilers, andprocess water for industrial and chemical processes which require softened water e.g. textiles.

Dealkalization by Suzhou X Chemical's weak and strong cation resins is accomplished by exchange of hydrogen ion forhardness ions. This process reduces the Bicarbonate Alkalinity and the pH of the treated water. They aretypically regenerated with HCl or H2SO4. Hydrogen ion combines with alkalinity to form carbon dioxidewhich is removed by degasification in a second treatment step.

Suzhou X Chemical provides a complete line of ion exchange resins made specifically for us in Ultrapure watersystems requiring 18+ megohms resistivity and ppt levels of ionic contaminants.All resins undergo treatment to remove the organic residuals that are left on ion exchange resins aftermanufacturing. All products are highly regenerated in the H+ and OH-forms.They are available in both Gaussian and uniform particle size distributions. Cation and anion componentscan be provided separately or as premixed mixed beds for ease of start-up and use.Every batch of GSCresin is tested to this standard prior to shipment these resins meet >18.2 MΩ·cmquality

Suzhou X Chemical offers several nitrate selective ion exchange products based on higher amine functionalitiesand also provides standard Type I and type II strong base anion resins that can be used for nitrateremoval.Although all strong base anion resins prefer nitrate over chloride, at TDS suitable for potable water, thestandard type I and type II resins prefer sulfate over nitrate. This preference can result in dumpingnitrates, acondition where the resin adds nitrate to the finished water instead of removing it.XResin’s nitrate selective resins have increased selectivity for nitrate and prefer nitrate over sulfate andother anions, even at very low TDS. This increased preference prevents nitrate dumping. In waters thathave high sulfate concentrations the nitrate selective resins also enjoy higher operating capacities thancan be obtained from the standard type I and type II anion resins

"Suzhou X Chemical manufactures a gel type strong base anion resin with higher amine functionality that is highlyselective for perchlorate and can remove traces of perchlorate from drinking water that contains very highconcentrations of nitrate and other anions.The combination of high capacity and high selectivity makes XResin perchlorate selective anion resin the most cost effective choice for perchlorate removal systems "

"Arsenic is a known carcinogen, increasing the risk of cancer even at very low concentrations. Arsenic occurs naturally in many groundwaters throughout the USA, less commonly in surface waters. With the recent passage of new limits restricting arsenic levels in potable water, many public water supplies require arsenic reduction prior to use. Although there are many treatment technologies available for arsenic reduction, one of the simplest methods is to use an arsenic selective adsorbent media. This type of system is well suited for residential systems as well as larger commercial and municipal systems, requiring little or no maintenance and only periodic monitoring. Suzhou X Chemical manufactures a unique arsenic selective adsorbent resin hybrid BAR-1FD. It is WQA certified to meet the ANSI/NSF 61 standard for potable water. "

Ion exchange resins and adsorbent medias are often ideally suited for removal of specific contaminants and/or for polishing the effluent from other wastewater treatment processes. Suzhou X Chemical provides a large number of products for wastewater treatment including chelating resins, resins suitable for organic scavenging and resins for selected removal of specific contaminants, such as boron,XResin’s ion exchange resins are available in many container sizes, mesh sizes, and can be specially prepared to be pH buffered or in a specific ionic form, ready to use. Many of these products are also available with the WQA Gold Seal certification to the ANSI/NSF 61 standard for potable water

"Naturally occurring surface water contain dissolved organics such as humate, fulvates and tannic acids. When chlorinated, they can lead to high levels of toxic chlorinated organic compounds. These organics can foul ion exchange resins, particularly anion resins. They also contribute to aesthetically undesirable drinking water by causing high levels of color, odor and unpleasant taste. Suzhou X Chemical provides a variety of anion exchange resins for the removal of naturally occurring organics from water. These resins are designed specifically to provide rapid efficient exchange for large organic ions both in the removal process and during regeneration. Removal of naturally occurring organics results in finished water with less color and odor, making the water more amenable to chlorination. XResin’s organic removal resins are all WQA Gold Seal certified to the ANSI/NSF 61 standard for drinking water "

"Condensate Polishing is normally applied to the treatment of condensed steam from turbines operating in the power industry. It is a specialty application where ion exchange resins are used for removal of corrosion transport products as well as removal of trace ionic impurities. This requires the use of resins that have excellent filtration characteristics as well as ion exchange capacity, and that can withstand the high temperatures and flow rates encountered in condensate systems. Polishing resins must also have low levels of both organic and ionic impurities such that they do not leach any objectionable contaminants into the treated water Suzhou X Chemical offers a variety of coarse grade and uniform particle size resins specifically for condensate polishing, including highly crosslinked resins with excellent thermal stability. These resins are available in a variety of ionic forms such as ammonia and amine forms for cation resin and hydroxide form for anion resin, suitable for imme
