dc.description.abstract | The increasing need for clean water is in line with the increase in population. In other words, the faster population growth will also accelerate the decline of the water supply per capita. The use of well water is carried out to meet the needs of clean water, especially drinking water. Uncontrolled use of well water coupled with a bad city planning system will result in contamination of well water. This research was conducted to determine the reduction efficiency of Total Coliform, Total Suspended Solid and Fe (Iron) in well water using ceramic membranes with variations in material composition and sintering temperature. This ceramic membrane is made using clay-based ingredients with a mixture of rice husk and moringa seed powder additives, with the size of the material used is 30 mesh and in the form of a pot (filter pot) with a diameter of 24 cm and a height of 20 cm. The variation of sintering temperature used in the making of ceramic membranes is 8000C and 10000C with the ratio of the composition of the ceramic membrane materials, clay, rice husks, and moringa seed powder, namely (65: 30: 5%), (70: 25: 5%), and (75: 20: 5%).
The results of this research showed that ceramic membrane number C75-1000 with a mixture of 75% clay, 20% rice husk, and 5% Moringa seed powder, which was burned at temperature 10000C, can reduce Total Coliform with the highest efficiency is 79.1%, Total Suspended Solid with the highest efficiency is 97% and Fe (Iron) with the highest efficiency is 95.8% with a permeation time is 14.1 hours. The results of the Scanning Electron Magnetic (SEM) test showed that the ceramic membrane number C75-1000 had the smallest pore size that is 5μm. The results of the Fourier Transform Infrared (FTIR) test show that on ceramic membranes made with different material compositions and different sintering temperatures there are 5 ionic bond groups formed as, OH stretch (alcohol), CH stretch (CH3, CH2, CH, CH aldehyde), CO stretch (acids, aldehydes, ketones, esters), COO- (carboxylates), COC (ether) alkyl substitution. The results of the Response Surface Methodology (RSM) test show that the proportion of ceramic membrane material that can produce optimum pollutant reduction efficiency is clay (x1) of 75.46%, rice husk (x2) by 20%, Moringa Oleifera seed powder (x3) 4.5% with a temperature of 11000C for Total Coliform, clay (x1) by 80%, rice husk variable (x2) by 15%, Moringa Oleifera seed powder (x3) of 4.14% with a temperature of 11000C for Total Suspended Solids, and clay (x1) by 80%, rice husk (x2) by 15%, Moringa Oleifera seed powder (x3) by 4.2% with a temperature of 11000C for Fe (iron). | en_US |
