ABSTRACT
This research aims to determine the optimized model of raw water mixing
process having a high turbidity level, alum or Poly Aluminium Chloride
(PAC) and pump stroke to input the raw water taken from river. It is to
obtain the proportional composition and the optimized model for the setting
of parameter with the experimental design of Taguchi method in which the
process of mixing water such as 5lt/sec, 10lt/sec, and 15lt/sec and % of alum
water 5 ppm, 10 ppm, and 15 ppm with the installations of pump stroke that
are of 15 %, 20 % and 25 %. The dominant factor which influences the
average response is beneficial to choose the level of factor producing quality
of clean water and optimal mixing model. Model produced from this process
can be used as basis to find out the characteristic of raw water supply, and
design the mixing process of optimal alum dosage and the behavior of
floating particles (flock). The particles were later processed in SEM
(Scanning Electron Microscope) to uncover the microstructure content of
sedimentation result of the mixing process. With the finding of proportional
setting for parameter of raw water supply, it thus results clean water which is
proportional to the quality standard.
