EFISIENSI FILTER PASIR-ZEOLIT DAN FILTER PASIR-ARANG TEMPURUNG KELAPA udDALAM RANGKAIAN UNIT PENGOLAHAN AIR UNTUK MENGURANGI KANDUNGAN udMANGAN DARI DALAM AIR

摘要

Various processing method irrigate to lessen the manganese content from within its branch water follow the udelementary steps oxidation, sedimentation, and filtration. Various materials serve the purpose of media filter, udso that require to do a research to obtain the effective media filter alternative relate to the amount of udmanganese content able to be reduced, availibility of materials in location, and also its execution amenity. udResearch was done using filter dual media with two variation of materials that are sand-coal of shell of udcoconut, and sand-zeolit. Those materials choosed because of the avaibility of materials in location. Total udvariation of attempt is 18 variation, that are 3 obstetrical variation of Mn early ( 1, 3, and 5 mg / lt), 3 udvariation of addition of chemicals oxidant ( KMnO4ud, Ca(OCl)ud2ud and without chemical addition of oksidant), udand 2 variation of type filter ( filter of sand-coal of shell of coconut, and filter of sand-zeolit). Result obtained udfrom this research is filter of sand-zeolit more efficience thand filter of sand-coal of shell of coconut to lessen udthe manganese content from within water. Mount this efficiency is determined by characteristic of every udmaterials of compiler of media filter influencing ability of screening and adsorption. udKey Words : Manganese ( Mn), filtration, filter dual media.
