| dc.description.abstract | Contents of Fe and Mn on water which have flow standardization capacity which causes environment and
healthy problems. Content Fe and Mn in Nilasari Pabelan Kartasura have exceeded capacity standardized
are 3,163 mg/l and 1,012 mg/l. degradation of Fe and Mn can be done by sand zeolit filtration. The
purposes of this research are to know about some influences of thick sand zeolit filter on degradation of
contains of Fe and Mn. The method which used in this research are experiment which test experiments
pretest-post with control groups desig. Populations in this research are all of arthesis well in Perum Nilasari
RT 01 RW VI. Accounts of sample which used 20 liter, every practically used 5 liter to 3 more repeated.
Result of statistics use anova. The results of this research show are the influence of thick in sand zeolit
media on degradation contains of Fe and Mn. The result of laboratory test show that control of Fe and Mn
are 3,157 mg/l and 1,011 mg/ sand- zeolit have thick about 40 cm in contains of Fe and Mn about 0,265
mg/l dan 0,275 mg/l, thick of sand- zeoliot 50 cm have contains of Fe and Mn are 0,193 mg/l dan 0,164
mg/l, thick of sand- zeolit 60 have contains of Fe and Mn are 0,145 mg/l dan 0,077 m | en_US |
