Dantobrom® Product Range

Dantobrom® products are high performance, solid bromine biocides that offer cost-effective microbial control. The products, which come in briquette and granular form, are broad-spectrum bactericides, fungicides and algaecides that can be used for a variety of industrial water treatment applications.

Dantobrom is a halogenated dialkylhydantoin that functions as an effective microbiocide through the controlled release of active bromine and chlorine. Dantobrom is a fungicide, bactericide, algaecide, and molluscicide for recirculating and once-through fresh and salt water systems. It is also a slimicide for the manufacture of food and non-food grades of paper and paperboard. Dantobrom is also recommended to control bacterial, fungal, and algal slimes in evaporative condensers, recirculating cooling tower systems, influent systems, industrial wet scrubber systems, sewage systems, auxiliary water systems, photo processing wash water, air washers, and brewery pasteurizers. Dantobrom RW is an effective component of a total program to control biofilm in industrial water systems. Published studies show that the combination of free and combined halogen provided by Dantobrom RW is more efficacious towards biofilm then either free chlorine or free bromine alone. The increased stability of the combined halogen in systems with high halogen demand allows greater diffusion into the biofilm without losses due to unwanted side reactions.

Along with their novel hydantoin chemistry, Dantobrom® products provide a number of key benefits:

  • Improved wet and dry physical stability
  • Increased solubility
  • Higher purity by eliminating binders
  • Minimal corrosion
  • Suitable for both slug and continuous feed
  • Compatible with other water treatment additives
  • To be dosed via brominators

Dantochlor® Product Range

Dantochlor® products are halogenated dialkylhydantoins that function as a microbiocide through the controlled release of active chlorine. The products are an effective bactericide, fungicide and algaecide for recirculating and once-through fresh and salt water systems. They are also an effective slimicide for paper mills that manufacture food and non-food grades of paperboard.

The Dantochlor® products reduce bacterial, fungal and algal slimes in evaporative condensers, recirculating cooling tower systems, influent systems, industrial wet scrubber systems and brewery pasteurizers.

These products are an effective component of a total program to manage biofilm growth in industrial water systems. Published studies show that the combination of free and combined halogen provided by the Dantochlor® products is more efficacious towards biofilm than either free chlorine or free bromine alone. The increased stability of the combined halogen in systems with high halogen demand allows greater diffusion into the biofilm without losses due to unwanted side reactions.

  • Dantochlor® Powder dissolves faster than the briquette form, is available in super sacks and is to be dosed via a dedicated feeder.
  • Dantochlor® RW Briquettes can be used in pressurized systems like standard brominators and is available in 25 and 50 pound pails.

Dantoin® BCDMH

As a powerful disinfectant and an effective, broad-spectrum bactericide and fungicide, Dantoin® BCDMH aids in the control of bacterial, fungal and algal slimes in diverse applications such as:

  • Commercial and industrial cooling systems and scrubbers
  • Paper mill process water (paper used in packaging for food contact and non-food contact materials)

Dantoin® BCDMH comes in tablet, power and granular forms.

hth® Scientific™ Product Range

hth® Scientific™ products are used as oxidizing agents in sewage water, waste water, cooling water and many other water systems.

With a powerful active ingredient of Calcium Hypochlorite, our hth® Scientific™ solution is an effective bactericide and fungicide, aiding in bacteria and algae control as well as helping to eliminate odours. hth® Scientific™ products are available in tablet, chips and granular form.

Advantages

  • Effective bactericide and fungicide, aiding in bacteria and algae control
  • Help to eliminate odours
  • Lower storage and transportation costs compared to liquid alternatives of a lower concentration
  • Due to a high concentration of the active ingredient, a relatively small amount of the product can effectively disinfect large amounts of water

hth® Scientific™ Bromine Floater

Bromine is an effective bactericide and fungicide for the disinfection of water in cooling water system.  It also helps to control the growth of biofilm within the system that could serve as potential breeding grounds for bacteria and fungi.  The HTH® Scientific™ Bromine Floater was designed for cooling tower sumps with volumes up to 20 000 Litres.  The unit is packaged in a disposable floating dispenser making it simple to use with low operator involvement.

  • Application: Small to Medium-sized Cooling Towers
  • 1 Floater can be used in sump volumes of up to 20,000 litres
  • Provides a slow release of active ingredient without leaving a residue
  • Rate of product release will depend on water temperature and circulation rate
  • Can operate at a wide pH range
  • Ability to aid in the control of biofilm growth can contribute to cleaner heat exchanger surfaces
  • Product packaging size: 350 g floater containing BCDMH tablets
  • Available in 6 units/case

Wysiwash Hard Surface Cleaner

The Wysiwash is designed for hard surface cleaning.  The hose end applicator attaches to a hose and uses Calcium Hypochlorite to create a 75 or 250 ppm AvCl Solution for disinfection.  This product is EPA-registered and works with either cold or hot water.
