The determination of sludge characteristics of wastewater treatment process has the
primary role in the treatment and disposal. This research aims to determine the sludge
characteristics by studying specific resistance factor of the sludge on the f
iltration at Merge
Maarban station, so we took samples of sludge from the station and made several
laboratory experiments and we got the time of intensify sludge, moisture and The
concentration of the solid substances. we calculated specific resistance factor values of the
sludge when the moisture values are ( 97.5 , 95.5 , 94 , 92 , 91 , 88 ) %. The research
results showed a decrease in resistivity factor value of sludge on the filtration as its
moisture become less and the sludge drying time takes tow weeks.
