WWT BIO-BLOCK is a slow dissolve, bacterial-laden solid for use in degrading organic waste in higher flow systems such as lift stations, wet wells, etc. The safe, application-specific bacteria are present in high numbers to handle difficult organic problems. The unique block will dissolve gradually which allows for continuous treatment and degradation of waste. The naturally-occurring specific bacteria contained in the block will reduce odour, sludge, sewage, sludge and treat effluent water.


Provides round the clock waste degradation treatment with a simple, easy to use system. Simply suspend the solid into the treatment area, allowing the solid to be submerged in direct water flow. The solid will dissolve over a 35-120 day period, depending on size and flow rates in a typical grease trap providing optimal efficiency and treatment.
