SIDE STREAM FILTRATION CASE STUDY

CHILLED WATER (CHW) AND LOW TEMPERATURE HOT WATER (LTHW) SIDE STREAM FILTERS FOR ST PANCRAS INTERNATIONAL STATION

Once the system was up and running we discovered that the initial Side Stream system selected was inadequate for the solids loading generated during normal operation. Fortunately, by involving Amazon at an early stage, a number of issues were identified and a solution put forward. This has resulted in a much more effective heating and cooling system and trouble free operation.

ABOUT THE PROJECT St Pancras International Station underwent substantial construction work due to it becoming an integral part of the High Speed 1 (HS1) project. Its direct link to Stratford International and Ebbsfleet International Stations and the Eurotunnel was expected to generate a significant increase in passenger usage. Therefore new heating and cooling systems were installed and these were fitted with preliminary Side Stream filters.

PROJECT CHALLENGES Following an initial period of operation, it was identified that upgraded filter systems were required to ensure maximum performance of this critical system. A full system performance evaluation and water analysis were carried out and it was identified that additional filters should be installed at the end of each loop on the primary circuit and at mid-point feeding secondary circuits. This was particularly challenging due to the large system volume, its complex design and layout and the high solids loading in the water.
