Oxidizing Biocides

Oxidizers are effective against all types of microorganisms in cooling systems, including bacteria, fungi, algae, and yeast. Our STA-BR-EX™, ControlBrom™, ACTIBROM™ and Purate™ products can effectively reduce the amount of oxidizing biocide required to control microbiological activity in cooling water. 

Non-oxidizing Biocides
Unlike oxidizers, non-oxidizers are more effective when applied in slug doses to target specific organisms. It’s best practice to use a non-oxidizer in conjunction with an oxidizer to maintain control of cooling water systems. We offer an array of compounds to ensure the right treatment for your cooling system.

Macrofouling Control

For control of macrofouling by zebra mussels and other mollusks, we offer effective molluscicide treatments that can be used in fresh and potable water systems. Your sales engineer can help choose the right treatment programme for your system.

Algaecides

Algae can be more difficult to control on a common biocide treatment plan. Nalco Water offers products to beat algae in cooling systems and ponds including potable water.
Biodispersants

Biodispersants should be used as part of a complete biocontrol programme. They will break up biofilms and suspend bacteria so they are more readily killed by biocides.

Water Safety

Environmental Hygiene Services provides specialized services to help control private and public health risks due to pathogens such as Legionella. They conduct detailed risk assessments and offer ongoing management programmes customized for your specific environment.
