Waste-water recycled

Two Aqua-Save waste-water recycling systems are now fully operational at Iracroft Ltd in Dorset, which makes hydraulic tubes and assemblies. Technical and engineering manager Pete Lewis says: “We use a series of caustic-wash tanks around the premises, and these unavoidably produce waste water in volume. Until we installed the Aqua-Save units, a tanker had to visit the site about every three weeks to remove the waste solution. Now, we expect such visits to take place no more than three times per year, which points to rapid payback on the installation and on-going cost savings thereafter.”

An Aqua-Save 30 has been positioned alongside the main dump washer at the site, which contains some 4,600 litres of caustic cleaning solution. Its stable-mate, the Aqua-Save Junior, is moved around and attached to a series of smaller tanks, typically holding some 200 litres.

“We have about 130 machining stations in the factory, which we believe makes us the largest manufacturer in our field in the UK, and it is very important that the inhibitor used during the production process is removed. The wash tanks are therefore vital, and their operation has been significantly enhanced in all cases by the Aqua-Save units.”
