Published on

In November we, at HydroChem, sponsored a series of technical seminars along the eastern seaboard. The seminars were timed to coincide with Australia’s seasonal shift, and provided a comprehensive look at the control and management of Legionella both here and abroad.

The series was titled Sydney’s Summer of Legionella – Clive Speaks and the keynote presentation was delivered by renowned Legionella authority and chair of AS/NZS 3666: Air-handling and water systems of buildings - Microbial control, Clive Broadbent, AM.
