Apart from the build-up of excessive heat in fluid power systems, failures as a result of contamination are at the very top of any hydraulic engineer’s list of potential causes. More specifically, contaminants equal to or harder than the material make-up of the system components themselves are the root cause of excessive wear. Yet conventional filtration can let them through to system components where they can do the most damage. Jobey Marlowe of Magnom reports on some recent developments.

Effluent should be recycled back into brewery operations with less reticence than is currently the case, according to South African wastewater specialists Talbot & Talbot. Throughout many parts of the world there are areas or entire regions where water is scarce and water quality highly suspect. In these situations beer quality is often compromised and production schedule disrupted. The use of properly treated effluent presents the brewer with a safer option and greater security of supply.
