SmartFoam sensor

Posted: Monday 28th October 2013

Foam is an expensive problem in many process industries but now a technology company, based in Kent, UK, has the solution.

Charity Technology Ltd. has developed a new smart sensor to save manufacturing industries time and money and to improve the quality of their waste before disposal.

The Charis SmartFoam System is available throughout the world, as an OEM component or as a stand-alone sensor, delivered directly to the customer. Initially developed for the exacting standards of the pharmaceutical industry, Sales Director, Steve Gallagher, soon recognised its value in effluent treatments and other industrial processes such as paper manufacture, veterinary products, chemical production and food processing.

Foam occurring naturally during many production processes blocks filters and overflows, causing a mess and safety hazard which results in costly downtime. Dosing with anti-foam reduces the problem, but without a reliable foam sensor many companies resort to constant dosage, which can often add up to over-dose. The Charis SmartFoam System, with patented IMA Sensing® technology, offers continuous monitoring to ensure optimum use of costly anti-foam.

Monarch Chemicals of Sheerness, Kent, is a chemical distribution and toll manufacturing company which takes its environmental responsibilities seriously. The company is justifiably proud of its ISO status and is a member of the Trade Association Responsible Care Programme. Disposal of residues from its chemical production is also subject to Southern Water’s strict regulations.

Projects Manager, Trevor Goddard, explains: ‘Our search for a solution to the problem of costly foam spillages during waste water treatment led us to WMEC Ltd., who designed and developed a fully automatic break tank system with computer controlled dosing and pumping, activating dosage of antifoam chemicals only when necessary. We asked them to incorporate a Charis SmartFoam sensor into the bespoke system.’

Steve Gallagher was able to customise the Charis SmartFoam sensor to respond to the new computer-controlled system, supplying it to WMEC as an OEM component.

Ken Hiscock, MD, WMEC, was delighted with the performance: ‘I wouldn’t hesitate in recommending it to our clients throughout the world,’ he says

‘As with many simple ideas, it is relatively easy to tailor the sensor to an individual client’s needs. It can also be incorporated into other manufacturers’ systems, offering an intelligent solution to foam control,’ says Steve Gallagher.

‘Since installing the Charis Foam Control System six months ago, our usage of anti-foam chemicals has drastically reduced and foam spillages are non-existent. We are confident that the system is monitoring our waste water 24/7,’ says Trevor Goddard.
