Coopervision uses Scalewater Enigma units from ETC

Scalewatcher Enigma units from Environmental Treatment Concepts (ETC) have been fitted to four of Coopervision's autoclaves to resolve a scaling problem.

Since 2001, ETC units have been fitted to the humidifiers at the registered office of Coopervision in Fareham, Hampshire, an area noted for its hard water.

From its network of facilities in 12 countries across five continents, Coopervision, a manufacturer of contact lenses and toric lenses, distributes its products globally, with a special focus on premium speciality lenses.

In 2007, a different scaling issue presented itself in the four autoclaves, which produced steam, resulting in extra maintenance as the autoclaves needed to be stripped down and cleaned every four to six weeks.

As the company operates continuous manufacturing, producing thousands of contact lenses daily, this affected productivity levels.

In December 2007, Mark Potter of Coopervision was referred to ETC.

After consultation, Scalewatcher Enigma units were fitted to the autoclaves.

By January 2008, a significant change had been noticed and, by February, it was confirmed that the loss of productivity was reduced and less maintenance was required.

A 750ml water sample was taken from the steam generator prior to the fitting of the Scalewatcher Enigma unit and then again six weeks later.

A vast improvement was seen in the reduction of scale in the beakers after evaporating the sample.
