Unit allows continuous TMF disposal

Oxfordshire-based group Microbial Solutions has launched the latest version of its bioreactor for continuous disposal of toxic metalworking fluids (MWFs).

The latest design incorporates modular continuous flow capabilities and builds on the company's existing microcycle technology, which has recently undergone trials at BAE Systems' Brough facility.

The technology is aimed at replacing MWF clean-up systems, such as vacuum evaporation and ultra filtration, which are energy intensive and produce oily waste residues.

Will Pope, chief executive of Microbial Solutions, said: 'Overall we think our bioreactors are around 50 per cent of the cost of the classical competition in terms of energy efficiency. Unlike the other systems, we don’t have to heat up to great temperatures or use huge pressures.'

The system works by treating MWFs in a bioreactor that carries a selection of bacterial cultures. When mixed with the MWFs, the bacteria are able to reduce the toxic levels of the fluids by up to 98 per cent.
