Hong Kong University of Science & Technology Outdoor Swimming Pool
The Site: The outdoor swimming pooi has three sand filters, two carbon filters and one ozonator. The ozonator broke down regularly, whenever the temperature in the operating room was too high. The Ozonator was used because management wanted to reduce the chiorine dosage from 3ppm to lppm. Back washing frequency of the sand filters was weekly and the carbon in the carbon filters was replaced ...

Using the STS Siloxane Monitor on sites with Activated Carbon Filters - Case Stdudy
Activated carbon filters work by passing the biogas derived from the AD plant through a metal tower filled with activated carbon. Normally the gas will have been dried by running through a chilling plant to remove excess water which would be absorbed by the Carbon. The siloxanes and other contaminants are trapped by the carbon allowing the filtered gas to pass through and into the engine. The ...
