THE RIGHT CHEMISTRY
Our products are used to produce, purify and recover some of the most commercially important products around the world and set the industry standard for quality and performance.
From feed stock purification to the purification of brines that make chlorine gas and metal hydroxides, Dow Water & Process Solutions offers a full range of products and technologies to help your operation run at peak levels.
CHEMICAL PROCESSING SPECIALTY APPLICATIONSFrom purifying adiponitrile to the production of methyl formate, our chemical processing expertise has helped companies thrive in a highly competitive field.
Adiponitrile is used as a precursor to manufacture nylon. The production of adiponitrile, however, can produce impurities. Our strong base anion and strong acid cation resins can purify adiponitrile.
|AMBERLYST™ 40 Ion Exchange Resin|
Biodiesel is a fuel derived primarily from the alcohol esters of vegetable oil and used as fuel for transportation, stationary power and more. From feedstock to final product purification, we offer a full range of products used in the manufacture of biodiesel fuels.

|Feedstock Purification||AMBERSEP™ BD19 WET Ion Exchange Resin|
|AMBERSEP™ BD10 DRY Ion Exchange Resin|
Boron is a natural element that can be found in coal and other fossil fuels and is used in commercial products such as detergents. Our selective ion exchange (IX) resins help meet discharge or product requirements.
|AMBERLITE™ IRA743 Ion Exchange Resin|
Chloride is a common contaminant in sodium hydroxide, but for many applications, low-chloride caustic is required. Our unique amphoteric ion exchange (IX) resin, containing both weak acid cation and strong base anion functionality inside the beads, has proven to be a reliable and economical solution.
|DOWEX™ RETARDION 11A8 Ion Exchange Resin|
The only economic method for producing commercial quantities of chlorine gas and metal hydroxides is through the electrolysis of brine solutions in a chlor-alkali cell. Our ion exchange (IX) resins are instrumental in purifying chlor-alkali brines to protect investments in electrolytic cells and reduce maintenance costs.

|Mercury Removal||AMBERSEP™ GT74 Ion Exchange Resin|
|Sulfate Removal||DOW™ Specialty Membranes XUS290508 High Temperature NF Element|
|DOW™ Specialty Membranes XUS290504 High Temperature NF Element|
Silica can exist as a polymer, referred to as colloidal silica, but will easily break down and volatilize under high temperature and pressure. Our membrane treatments such as reverse osmosis and ultrafiltration are effective at removing virtually all colloidal silica.
|AMBERLITE™ IRC84SPHi Ion Exchange Resin|
Sulfuric acid is typically used in the production of phenol and acetone. It’s necessary, however, to remove traces of sulfuric acid prior to downstream distillation. Our weak base anion (WBA) resin technology has successfully been used to remove sulfuric acid for many years.
|AMBERLYST™ A21 Ion Exchchange Resin|
|AMBERLYST™ A22 Ion Exchange Resin|
|AMBERLYST™ A23 Ion Exchange Resin|
|AMBERLYST™ A24 Ion Exchange Resin|
Ethylene glycol (EG) is produced industrially by the hydrolysis of ethylene oxide (EO). The quality of the water used for hydrolysis is of critical importance. Our weak base anion (WBA) and strong base anion (SBA) exchange resins have been proven successful in removing impurities such as formic or acetic acids.
|AMBERLYST™ A15 Polymeric Catalyst|
|AMBERLYST™ A21 Ion Exchchange Resin|
|AMBERLITE™ IRA900 Ion Exchange Resin|
Formaldehyde is the simplest of the aldehydes and the most commercially important. It’s made from the oxidation of methanol. Formic acid is an unwanted byproduct of this process. Our weak base anion (WBA) resins have been proven effective in the removal of formic acid from formaldehyde.
|AMBERLYST™ A21 Ion Exchange Resin|
Hydrogen Peroxide (H2O2)
Hydrogen peroxide is used as a chemical reagent for oxidation. The production process may generate low levels of dissolved organics (generally, derivatives of quinone). With careful attention to the possibility of dangerous oxidation of the resin, our polymeric adsorbents can be used to remove these organics in order to produce high-purity hydrogen peroxide.
|AMBERLITE™ XAD™4 Polymeric Adsorbent|
When metals (chromium, cadmium, nickel, copper, lead and zinc) are added to a plating bath, some of the metal ions get rinsed off. These can, however, be recovered in the rinse water both to save raw material cost and to avoid discharge.

|DOW™ XUS-43600.00 Ion Exchange Resin|
Various chemical processes produce salt in concentrated or even dry form, i.e. fertilizer production. Ultra-high pressure RO allows to concentrate these salts higher than standard RO elements.
