Given its resource potential in Indonesia, Coal Bed Methane’s (CBM) potential as alternative energy is quite large. CBM resources of Indonesia amounted to 453.3 TCF in 11 Basins. Water is produced in large quantities from dewatering processes isof varying quality ineach basin. In its utilization there are several quality parameters of CBM produced water wells "X" field “Y” that do not meet quality standards based on Government Regulation of Enviromental No. 02 of 2011 on Wastewater Quality Standard Business and/or Activity Exploration and Exploitation of Coal Bed Methane, because heavy metals are still present in produced water. Ceramic membranes can solve this problem, they can be made from various materials readily available, one with a mixture of industrial waste ceramics (Grog), clay (Clay), and coal ash. Ceramic membranes act as a very specific filter that have a size macropores (> 50 nm) were able to reduce TSS, Turbidity, protozoa, oocysts, Cysts, some bacteria and viruses, so that only molecules of a certain size can pass through the membrane while the rest are stuck on thesurface. From the results of this filtration the filtrate obtained in the form of clean water which is then separated from the heavy metals contained in the produced water. From the results of the processing, the produced water can be out flowed as river water, formation water, freshwater fisheries, livestock, irrigation, washing coal, industrial process water, as well as drinking water by using reverse osmosis method.
