Pilot trials of ultraviolet (UV) irradiation, ozone addition, and hydrogen peroxide
(peroxide) addition for the control of biofouling and microbial action in fresh
water cooling towers in water-cooled air conditioning systems (WACS) were
conducted at an industrial site in Tai Po, New Territories, Hong Kong. The pilot
site had 4 separate independent cooling water circuits, each with 1 chiller unit.
All the cooling towers were located on the rooftop of the building. The chiller
units were located on various floors inside the building. Testing was conducted
over a period of about 6 weeks to determine the effectiveness of the processes.
In addition to the cooling circuits that were using either UV, ozone, or peroxide,
a control test was setup in the smaller fourth cooling circuit.
