An advanced liquid treatment to control the build-up of floating and settled solids in grey water storage tanks and pipework. This in turn controls malodour and septicity and reduces the frequency of pump outs.

The easy-to-use liquid formulation contains a blend of bacteria selected for their ability to degrade a wide range of organic materials found in grey water. These include fats, oil, greases, protein and starch, soap (and other detergents) and cellulose from toilet paper that arise from all normal galley and accommodation use.
