Corrosion inhibitors are chemical products which, when added to water or to any other process fluid, slow down the rate of corrosion. The effectiveness of most corrosion inhibitors is significantly affected by the water’s chemical properties and by physical conditions such as temperature and flow velocity. Brenntag offers a comprehensive range of products that can perform well in a variety of conditions.

  • Copper Corrosion Inhibitors
  • Filming Amines
  • Hydroxyphosphonoacetic Acid (HPA)
  • Neutralizing Amines
  • Oxygen Scavengers
  • Sodium Nitrite
  • Tolyltriazole
  • Other WT Corrosion Inhibitors

Brenntag’s defoamer portfolio includes basic silicone-based defoamer technology, but also many others. The wide range of products provides solutions to a variety of application challenges.

Brenntag Water Treatment offers an extensive range of anionic, nonionic, and cationic flocculants.

  • Anionic Flocculants
  • Nonionic Flocculants
  • Cationic Flocculants

Emulsions and dry flocculants are available ranging from very high to low molecular weights, and are also available in linear or structured (branched).

Branched or structured polymers deliver exceptional performance when used on centrifuge dewatering applications. The violent actions within a centrifuge expose substantially more charge sites which in turn produces a dryer more stable sludge cake.

As wastewater metals discharge limits become increasingly strict, there is a growing need for effective but also safe environmentally friendly precipitants.

  • Hydroxide Precipitation: although effective, cannot meet the new lower metals discharge limits required by many industries
  • Sulfide Precipitation: also effective but can have toxicity issues

The Brennfloc metals precipitants are effective in meeting these low discharge requirements, safe to use, and environmentally friendly.


  • Antimony
  • Beryllium
  • Cadmium
  • Copper
  • Lead
  • Nickel
  • Silver
  • Tin
  • Trivalent Chrome
  • Zinc

Inorganic coagulants neutralize the negative charges in water but also precipitate to create a metal hydroxide. Brennfloc inorganic coagulants of aluminum and iron salts cover a wide range of applications. Inorganic coagulants are effective as coagulants for suspended particles.


  • Aluminum Chlorhydrate (ACH)
  • ALuminum Sulfate (Alum)
  • Poly-Aluminum Chloride (PAC)
  • Sodium Aluminate


  • Ferric Chloride
  • Ferric Sulfate
  • Ferrous Chloride
  • Ferrous Sulfate

Ion-exchange resins are widely used in different separation, purification, and decontamination processes. The most common examples are water softening and water purification.

  • Condensate Polishing
  • Dealkalization
  • Demineralization
  • Organic Scavengers
  • Softening

Activated carbon is a porous material that removes organic compounds from liquids and gases by a process known as “adsorption.” In adsorption, organic molecules contained in a liquid or gas are attracted and bound to the surface of the pores of the activated carbon as the liquid or gas is passed through.

Powered and granular activated carbon in a variety of physical forms are available. Other types available depending on the application needs.

Applications include:

  • Air Treatment
  • Chlorine Removal
  • Color Removal
  • Gas Purification
  • Organics Removal
  • Precious Metals Recovery
  • Solvent Recovery
  • Taste and Odor Removal
