ABSTRACT:
This
paper presents a methodology for evaluating the water purification process
efficiency attained by 1) jar tests, which are commonly used to determine the
treatability of water, and 2) waterworks performance in different phases of the
purification process as well as in its entirety. This methodology provides an
important tool for the following: 1) determination of optimised reaction
conditions under which water is treatable to its best attainable quality; 2)
evaluation of the purification process efficiency attained by waterworks during
different periods and under different operational conditions; 3) comparisons of
performance efficiency of different waterworks; and 4) comprehensive
commissioning of waterworks and identification of bottlenecks if any exist in
process and plant design. This paper describes procedures for pre-processing of
water samples to be analysed as well as mathematical formulas for processing of
the results obtained. A few examples of the practical application of the
methodology are included and the potential to obtain the optimization of
waterworks’ purification processes is herein illustrated.
