Abstract
This research was undertaken to evaluate the adequacy of using a mass
balance technique with daily treatment plant data to,determine combined
sewer runoff and overflow characteristics.
An hourly simulator was utilized to generate known runoff and overflow
concentrations as well as plant concentrations, similar to raw treatment
plant data. The daily balance technique was used to analyze the simulated
treatment plant data which provided comparisons of the calculated to the
known runoff and overflow concentrations.
The bias and variability associated with the mass balance technique
together with a theoretical analysis of the plant measurement error effects
is presented. The unit loads and average concentrations from the NYC 26th
Ward Treatment Plant area as well as the effect of rainfall characteristics
on combined sewer runoff concentrations are also presented.
This report was submitted in fulfillment of Grant No, R 806519-01 by
Manhattan College under the sponsorship of the U. S. Environmental Protection
Agency and covers the project period June 1, 1979 to February 28, 1981. This
draft report has been submitted to EPA for publication.
