Abstract:
The quality characteristics of raw water sources in the
regional integrated drinking water supply system (SPAM)
of Banjarbakula were investigated and found to main tain the supply of drinking water quantity and quality in
accordance with drinking water standards. The optimum
model for the mixing process of raw water and poly alumi num chloride (PAC) and pump stroke for the input of water
sources from rivers to obtain a composition setting that is
in accordance with the raw water sources of each region
in the region was selected and determined. So the optimum
parameter setting model between alum water, raw water
and pump stroke for each raw water source is known and
is regionally integrated as a result of a comprehensive
study. The integration of Taguchi parameter design and
response surface can complement each other and become
two methods that go hand in hand in the process of opti mizing clean water products. Parameter design provides a
very practical optimization step, the basis for this forma tion refers to the factorial fractional experimental design.
However, the absence of statistical assumptions that fol low the stages of analysis makes this method widely cho sen by researchers and practitioners. With the experi mental design of the raw water mixing process, turbidity
such as 5 lt/sec, 10 lt/sec, 15 lt/sec, 20 lt/sec and 25 lt/sec
and % PAC concentration 5 ppm, 10 ppm, 15 ppm, 20 ppm
and 25 ppm with a pump installation stroke of 5 %, 10 %,
15 %, 20 % and 25 % were used. In the process of add ing PAC, always pay attention and observe the behav ior of the attractive force of the floating particles (flock).
The particles were then subjected to SEM (scanning elec tron microscopy) to determine the dimensions of the flock
grains deposited
