APPH, a manufacturer of aircraft landing gear, has installed a single processing unit from Aqua-Save Technologies, part of Mecwash Systems, to improve its machining wastewater disposal procedures.

The Nottingham site of APPH, part of the BBA Aviation Group, is dedicated to the production of a range of hydraulic systems.

This latest installation has improved the organisation’s environmental performance and is also set to help reduce waste disposal costs.

The development, which features an Aqua-Save Junior with a built-in preheat 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 of to drain, with only a fraction of the volume – typically about five per cent – requiring offsite disposal.

Geoff Brown, APPH’s maintenance engineer, said: ‘The collection of waste coolant from the machining installations has always been centred on waste being pumped into 1,000-litre IBC containers until we had approximately 8,000 litres.

‘Before we installed the Aqua-Save system, we would then have this collected by a waste disposal company every six weeks at a total cost of some GBP5,000 annually.

‘This has now been dramatically reduced to perhaps one 8,000-litre disposal per year as the vast majority of waste collected is now converted by the Aqua-Save installation into either water for new coolant or water that can be used for other applications such as floor-cleaning operations,’ he added.

According to Brown, this ensures a rapid payback on the investment – with ongoing cost benefits for the organisation thereafter – and has also helped to maintain APPH’s environmental commitment.

Paul Jarratt, sales manager of the Aqua-Save Technologies division of Mecwash Systems, said: ‘APPH produces equipment and components in a range of materials, including aluminium and titanium alloys as well as stainless steel, some of which can be up to 6ft [1.8m] in length and each item passes through a series of machining stations.

‘The use of coolant and machine oil is substantial and eliminating the bulk of the waste disposal brings great financial and environmental benefits,’ he added.
