Biodispersant Para B9280

Dispersant “V 9280” is a liquid-phase surfactant designed to combat biological deposits in aquatic environments and to control the growth of algae and fungi in cooling water circulation systems. The dispersant prevents biofilm formation in circulating water systems and is used in plants with cooling water circulation systems in cooling towers. Sometimes it works as a non-oxidizing inhibitor. 

Dispersant “V 9280” is produced in accordance with the current technical conditions TU 2493-008-17423242-2004 with rev. one.

Protection of equipment for water circulation systems


Dispersant “V 9280” can be dosed into the water circulation system and other water circuits either continuously using a dosing pump or periodically. Dosing can be carried out directly from product drums or from working plastic containers.

The effect of the reagent begins to manifest itself, as a rule, after 4-6 hours, and in some cases intensifies over the next 1-2 days. A good bactericidal effect can be obtained when used together with “B 9280” with the inhibitor of biodegradation “B 9007” and the dispersant “B 9275”.


The dosage of Dispersant “B 9280” depends on the degree of biological deposits, as well as on the degree of contamination of the system with microorganisms. Intermittent dosages of 10 to 50 g / t based on system volume over a period of 1 to 2 weeks are typical. In heavily contaminated systems where reagent treatment has not been carried out for a long time, more frequent treatments with dosages of up to 100 g / t are recommended. The disappearance of algae is observed visually within 3-6 weeks. Removal of biofilm and
