Bio Productions BD Bio Dose Grease Trap & Drain Maintainer Bio Dose is a stable liquid containing the same selected microorganisms and enzymes as Bio Clear that efficiently reduce the waste typically evacuated into the drainage systems of kitchens and other catering and food processing units. Bio Dose is suitable for use in all types of drains, sinks and small bore pipes, as well as for maintaining septic tanks, grease traps and complete sewerage systems. Bio Dose has a two stage operation. When activated with water, the free enzymes quickly break down the waste into smaller pieces, which are more accessible to the microorganisms. This initial degradation immediately improves the drain flow rates and reduces odours. It also enables the various strains of microorganisms in Bio Dose to quickly continue the degrading process, further reducing the smaller particles of solid waste (such as fat, paper, and vegetable trimmings) into liquids and gases. - Degrades grease and solid waste - Ne
