Corrosion of concrete sewer pipes induced by sulfuric
\r\nacid is an acknowledged problem and a ticking time-bomb to sewer
\r\noperators. Whilst the chemical reaction of the corrosion process is
\r\nwell-understood, the indirect roles of other parameters in the
\r\ncorrosion process which are found in sewer environment are not
\r\nhighly reflected on. This paper reports on a field studies undertaken
\r\nin Austria and United Kingdom, where the parameters of
\r\ntemperature, pH, H2S and CO2 were monitored over a period of time.
\r\nThe study establishes that (i) effluent temperature and pH have
\r\nsimilar daily pattern and peak times, when examined in minutes
\r\nscale; (ii) H2S and CO2 have an identical hourly pattern; (iii) H2S
\r\ninstant or shifted relation to effluent temperature is governed by the
\r\nroot mean square value of CO2.<\/p>\r\n","references":"[1] J. Vollertsen, A. H. Nielsen, H. S. Jensen, T.W. Andersen and T.
