Abstract

Peat water is the kind of surface water that which widely available in the swampy area and lowlands that require more treatment so that can beclassified as a clean water and can be drunk. One of the alternative technology that can be used for peat water treating is membrane technology. The first challenge of the membrane technology is fouling. The purpose of this research is to learn the affectivity and efficiency of the cleaner materials likeNaOH and detergent in the regeneration process of ultrafiltration membrane at the peat water filtering operation. This research was done by using ultrafiltration membrane that the peat water as the feed. The used methodwas cross flow system with variations were pressing operation 1 bar and 1,5 bar and concentration of NaOH and detergent 1%, 1,5%, and 2%. The filtering process of peat water carried on for 120 minutes and the each cleaning time was 20 minutes. The highest of cleaning affectivity was reached 21,14% using detergent 2%. The highest of cleaning efficiency based on recovery flux was 84,88% and based on resistance removal was 21,09%.Key words : Cleaning affectivity, cleaning efficiency, peat water, ultrafiltration membrane

Abstract

The shortage of availability and increasing prices of Liquefied Natural Gas (LPG) encourage some people to use firewood as an alternative to traditional cooking fuel. The utilization of conventional stoves for combustion results in the generation of carbon monoxide (CO) emissions which can be dangerous to human health. Gasification stoves produce less CO emissions than conventional stoves and produce thermal efficiencies up to 35%. The shortage and high expense of LPG can be avoided by using biomass waste, such as twigs, wood chips, and palm fronds, as fuel for gasification stoves instead of kerosene or LPG. The gasification stove used in the socialization was designed based on the dimensions of the Champion Stove Top-Lit Up Draft. Wood logs that have been cut to a size of 6–9 cm and a width of 1 cm are utilized as fuel. 1.5 liters of water were successfully boiled for nine minutes by KOMAS gasification stoves. This socialization activities attracted the attention community of Batu Belah Village and at the end of this socialization, the team gave gasification stoves to the local community as an effort to apply the technology.
