Hanovia News - a Halma PR news blog

British UV disinfection company Hanovia has appointed George Wang as its new China Country Manager. A subsidiary company of Halma p.l.c., Hanovia is one of the world’s leading UV disinfection system manufacturers for process water applications, with major installations in China, southeast Asia, Australasia, north and south America, Europe, the Middle East and Africa.

George has a Masters Degree from East China University of Science and Technology and has many years’ experience in research into various aspects of water treatment. His extensive knowledge of water treatment technology and UV disinfection will be very important in his new role.

“My role will be to help Hanovia develop partnerships with competitive sales and engineering companies in China which will allow us to offer the best, local service for our customers in this country,” commented George on his appointment. A highly qualified, dedicated individual, he brings to Hanovia valuable experience which will ensure the company maintains its position as a leader in UV technology applications.

Hanovia’s main markets in China are industrial users of process water such as semiconductor and pharmaceutical manufacturers, food, beverage and brewing, aquaculture and also operators of indoor swimming pools and spas.

Loch Fyne Oysters Ltd in Scotland has chosen two Hanovia medium pressure UV disinfection systems for its oyster farm in Loch Fyne, Cairndow, Scotland. The UV systems, which were installed by Barr and Wray, destroy harmful E.Coli bacteria from its oyster and  mussel depuration tanks. Each UV chamber treats up to 150 m3 water per hour.

According to a spokesperson from Loch Fyne Oysters, “The Hanovia units were recommended to us by Barr and Wray because of their 99.99% log reduction of E.Coli, their robust, stainless steel construction, their ease of installation and easy maintenance – including easy UV lamp replacement and daily cleaning with a manual wiper – and low running costs. We also find the digital run-time read-out very useful, and the price was very competitive.”

Hanovia UV systems can be used in farms and hatcheries to treat both incoming and recirculation water, allowing flexibility in the choice of site and a rapid payback for farmers. UV is ideally suited for this application as it uses no chemicals and does not create by-products which would harm the stock, or other aquatic life, on discharge. Unlike other treatment methods, UV also avoids the expense of complex monitoring systems involved in adding and removing chemicals before the water reaches the stock. In addition, it does not alter the pH of the water. Indeed, UV is the most economical disinfection technique that can be used in aquaculture.

Maintenance of the systems is restricted to the replacement of the UV lamps every 12 months, a simple operation that can be carried out by on-site staff. An automatic or manual wiper can be fitted over the quartz sleeve which surrounds the UV lamp to prevent the build-up of any deposits, ensuring maximum levels of irradiation at all times.

A significant feature of Hanovia’s systems is the Photon control panel which displays a range of useful functions such as flow rate, UV dose and intensity. It is capable of logging up to one year’s performance data, which can be downloaded to a PC through an RS232 port. Linked into a central computer, the control panel can also be operated remotely, and allows the system to operate around the clock.
