The costs come out in the wash

The Nottingham premises of APPH, part of the BBA Aviation Group, which produces hydraulic systems, has taken steps to enhance its machining waste water disposal procedures by installing a single processing unit from Aqua-Save Technologies, a division of MecWash Systems. The move has not only improved the organisation's environmental performance, but will also help reduce waste disposal costs, it is reported.

The development, which features an Aqua-Save Junior with a built-in pre-heat facility, is centred on the processing of waste coolant collected from each individual machining installation. The facility separates the material via a process of evaporation into water that can either be recycled or safely disposed to drain, with only a fraction of the volume - typically some 5% - then requiring off-site disposal.
