SIDE STREAM FILTRATION CASE STUDY
LOW TEMPERATURE HOT WATER (LTHW) SIDE STREAM FILTERS FOR AIR CONDITIONING SYSTEM AT HEATHROW TERMINAL 5
“
Due to successful operation at the Energy Centre, Amazon’s Side Stream filters were selected for the Terminal 5 air conditioning system. The filters were manufactured and delivered on time and met all criteria. More importantly, from an operational perspective, they have continued to support BAA on a practical level.

ABOUT THE PROJECT Due to the success of the Amazon Side Stream filters installed previously at the Heathrow Energy Centre, the same system was selected for a major project initiated to ensure the high performance and accurate control of the heating system operating in Terminal 5. The system volume was significant - in excess of 500,000 litres of water, therefore requiring the installation of 8 filter housings in each of the two main plant rooms.

PROJECT CHALLENGES Due to location and building construction the main plant rooms are located below ground and prone to ingress of contamination. This issue was managed by using 50µm DuoLine bag pre-filters for initial high solids removal followed by 20µm SupaPleat II cartridge filters for final polishing. The large system volume required the use of four 84 Series prefilter housings followed by four 63 Series polishing filter housings, all operating at 8-10bar. To ensure minimal fluid loss from the circuit there was also a need to install additional booster pumps.
