GT BioBlock breaks down FOG
GT Bioblock
Is a solid product intended for slow release of emulsifiers, bacteria to degrade the FOG, and odour counteractants resulting in a continuous, low maintenance treatment. The blocks are proven to completely dissolve in 4-6 weeks to fit with common service or inspection cycles.
GT BioBlock contains bacteria capable of degrading FOG. When combined with specific nutrients and slow-release oxygen sources they can continue to break down FOG at the very low dissolved oxygen concentrations encountered in almost all drain line applications.
GT BioBlocks products are designed to be used from point of discharge through the entire drain line system right up to the sewage treatment plant. The modular design means can suit various installations and to suit every application, larger or small, stored water or fast flowing effluent.
GNC Marine supplies GT Bioblock in 6 x 2kg packaging.
