Microbial diversity in a thermopilic UASB reactor producing biogas from palm oil mill effluent (POME) was investigated. The PCR-based DGGE analysis showed that the microbial population profiles changed with the temperature transition from mesophilic to thermophilic conditions. Acetotrophic and hydrogenotrophic methanogens were found in all three phases: the seed sludge, transition from mesophil...

the effect of organic loading rate (olr) provided by hydraulic retention time (hrt) and influent chemical oxygen demand (codin) on the performance of an up-flow anaerobic sludge fixed film (uasff) bioreactor treating palm oil mill effluent (pome) was studied. anaerobic digestion of pome was modeled and analyzed with two variables i.e. hrt and codin. experiments were conducted based on a general...

Residual palm oil that goes into the river untreated can become detrimental to environment. discharge during milling process mill effluent (POME) is unavoidable. About 1 wt% of residual in POME causes major problems mills, terms environment, wastewater treatment and economy losses. This paper reports recovery from by adsorption on polypropylene micro/nanofiber (PP-MNF) desorption hands pressing...

The interaction of a series of synthetic, branched trisaccharides with five D-mannose-specific lectins was studied by precipitation-inhibition assay. The branched methyl alpha-D-mannotrioside, alpha-D-Manp-(1----3)-[alpha-D-Manp-(1----6)]-alpha-D-Man pOMe, the best inhibitor of the Con A-Dextran interaction, was 42 times more potent than alpha-D-ManpOMe, and 3-6 times more potent than the two t...

The presence of abundant oil palm residues in Malaysia prompted the need to utilize this waste avoid environmental pollution. Palm mill effluent (POME) is a thick, brownish liquid comprising large amounts solids and high organic content, convertible into valuable source biomass. Based on nutrient content POME, has potential be utilised as an alternative plant nutrients medium different agricult...

Palm oil mill effluent (POME) is an oily wastewater generated by palm processing mills. Most factories and refineries have their own treatment system such as anaerobic digestion electrocoagulation (EC). In this study, a new method, integrated (EC)-membrane introduced to treat the POME. The efficiency economic feasibility of developed EC-membrane also evaluated comparing with EC standalone syste...

Pandemis Leafroller Study site description. MD as a control for pandemis leafroller (PLR) was evaluated at a single study site in 1992. Six apple blocks (23.6 acres) were treated with Hamaki-con (Biocontrol, Ltd.) dispensers. These dispensers contain ca. 150 mg of Z11-14OAc, which is the main component of the PLR pheromone. Application rates of 250 d/a, 400 d/a, and two treatments of 400 d/a we...

This research aimed to investigate the biogas production and circular economy perspective in palm oil industry through codigestion of empty fruit bunch (EFB) pressing wastewater mill effluent (POME). The EFB method constitutes an alternative new technology used extract remaining oil, increasing product; however, it produces highly polluted wastewater. Batch experiments were carried out at 35 °C...
