Evaluation of T90 Decay Rates for a Range of Micro-organisms Indicative of Sewage Contamination: Phase I - A Review of Documented Historical Laboratory-Based Studies and Field Applications
Price: £100
Ref: 04/WW/11/9
ISBN: 1 84057 353 8
The study aims to describe the decline of microbial indicator organisms and enteroviruses in water under natural conditions in which all relevant variables, in particular solar radiation, are either measured or controlled. The first phase of the study was to carry out a comprehensive literature review to determine and finalise protocols for the experimental work.
From the review an experimental system has been devised involving the exposure of water samples containing a range of indigenous and laboratory cultured micro-organisms to sunlight generated by a full spectrum, solar simulator. The review identified key variables that affect microbial mortality - salinity, temperature and turbidity - and these variables will be manipulated in the laboratory to generate test mixtures that represent a range of conditions typical of UK coastal waters. The microbial mortality rates measured for the range of conditions tested will be used to formulate predictive equations for incorporation into a single inactivation model.
