Product information

Unitor™ Gamazyme™ Biological Toilet Cleaner is specifically formulated to replace aggressive, toxic toilet cleaners that can disable the sewage treatment plant by killing the naturally occurring bacteria which are essential to its operation. Conventional toilet cleaners may also cause foaming in the vacuum inductor which destroys the vacuum in the sanitary flushing system.

Unitor™ Gamazyme™ BTC effectively cleans the toilets, dosing millions of selected safe bacteria into the sanitary system. These powerful specialised bacteria colonise the organic waste lining the pipe system and remove the organic deposit. On draining to the sewage treatment plant, the bacteria will enhance the biological activity, reducing solids and odours.

Grease, fats, starch and other organic compounds are digested by Unitor™ Gamazyme™ BTC. The degradation of paper, protein, waste product residuals and other odorous materials is also enhanced.

Unitor™ Gamazyme™ BTC cleans more thoroughly and deeply compared to conventional cleaning products. The use of cleaning products containing hazardous chemicals such as acids, caustics, bleaches, disinfectants, etc., can be reduced.
