ABSTRACT
ABSTRACT: The process industry in the UK uses vast quantities of potable water for process cooling. It is possible that this procedure could be carried out using lower quality water but this may cause heat exchanger fouling problems. Tests were done on canal water and sewage effluent in NEL’s cooling water fouling circuit to compare them with potable water. Fouling data were gathered as plots of fouling resistance against time. It was found that the sewage effluent fouled rapidly and severely but that the canal water performed similarly to the current potable supply and would be suitable for further investigation.
