Physical description[ edit ] Methanogens are coccoid spherical shaped or bacilli rod shaped. There are over 50 described species of methanogens, which do not form a monophyletic group, although all methanogens belong to Archaea. They are mostly anaerobic organisms that cannot function under aerobic conditions, but recently a species Candidatus Methanothrix paradoxum has been identified that can function in anoxic microsites within aerobic environments.
Oil palm fronds and oil palm crop residues Description Palm oil mill effluent is the voluminous liquid waste that comes from the sterilisation and clarification processes in milling oil palm.
An industrial oil palm mill produces about 2. Palm oil mill effluent is a highly polluting material and much research has been dedicated to means of alleviating its threat to the environment.
Since the s depending on the countrydevelopments have taken place in the crude palm oil industry to make it environmentally more sustainable, and wastewater treatment systems are now commonplace in the main areas of production Chavalparit, There have been numerous attempts to convert palm oil mill effluent into a viable animal feed resource.
Distribution Palm oil mill effluent is a fresh product available in the vicinity of oil palm mills. Environmental impact Palm oil mill effluent is a highly polluting material, due to its high biological oxygen demand BODlow pH and colloidal nature.
It was estimated that a processing plant with a capacity of 10 tons fresh fruit per hour would need a water treatment plant comparable to that required by a population of half a million inhabitants Brezing, While considerable progress has been made since the time when oil palm wastewater was simply discarded in nearby waterways, liquid oil palm wastes still affect the environment and the quality of life in rural areas.
Palm oil mills now employ conventional biological treatment systems, such as anaerobic and facultative ponds in series, anaerobic and aerobic lagoons in series, or anaerobic digestion tanks and facultative ponds in series. However, some mills are still not able to treat their wastewater in ways that meet effluent standards.
In the rainy season, overflow from the wastewater treatment plants causes heavy water pollution to nearby waterways. Another issue is that anaerobic ponds release greenhouse gases methane and carbon dioxide that contribute to global warming.
Communities located near oil mills may also suffer from odour emissions caused by poorly managed effluent treatment systems Chavalparit, Increasing the consumption of palm oil effluent by livestock, if possible near the production site to avoid wastage, palatability issues and transportation, has been proposed as a means to minimize pollution Devendra, Effluents from palm oil mills using wet process are lower in fat than effluents from mills using dry process Seephueak et al.
The variability in cell wall content is very large: As a result, the nutritive value of palm oil mill effluents should be assessed on individual samples. Potential constraints Palm oil mill effluent tends to concentrate major minerals and trace elements.
For instance, in Nigeria, the decanted sludge analysed by Bamikole et al.
Therefore, the use of this product in ruminant feed should be assessed carefully for potential mineral toxicity Seephueak et al. Field trials with buffaloes and cattle in oil palm estates have also shown beneficial results from supplements of palm oil effluent.
In feedlot cattle fed a In goats fed a basal diet of rice straw, 3: Poultry Fresh oil palm mill effluent is fat-rich but its high moisture content makes it difficult to incorporate in standard poultry diets Atuahene et al.
Other limiting factors are the low protein and amino acid contents, and the high fibre content Sinurat et al. There was no advantage in feeding fresh rather than dried fermented effluent in both broilers and native chickens Sinurat et al. Fish The use of palm oil mill effluent was studied in four Indian carp species, namely silver carp Hypophthalmichthys molitrixcatla Catla catlarohu Labeo rohita and mrigal Cirrhinus cirrhosus.
The fish were harvested after 9 months and the maximum individual growths of silver carp, rohu and mrigal wereand g respectively whereas the average growth of catla was Other species Palm oil mill effluent has been tested as a potential medium for growing animal species used to feed fish and other aquaculture species.
Sudanese fairy shrimp Streptocephalus proboscideus Dried palm oil mill effluent was evaluated in a closed recirculation system for its suitability to replace live algae Selenastrum capricornutum in the culture of Sudanese fairy shrimps, a live food in aquaculture.
Growth increase in lengthcyst production and mortality were generally similar to those obtained with more costly algae, though it was unclear whether this success could be attributed to the nutritional quality of the product or to the colonisation of adventitious micro-organisms, who may either increase the digestibility of the feeds or act as a supplement Jawahar Ali et al.
Insect larvae Chironomid larvae bloodworms are a valuable live food for fish or cultured invertebrates. The production of chironomid larvae was significantly higher in palm oil mill effluent than in algal Chlorella vulgaris cultures Habib et al.TREATMENT OF PALM OIL MILL EFFLUENT (POME) BY USING ELECTROCOAGULATION AS AN ALTERNATIVE METHOD The treatment of palm oil mill effluent (POME) is a crucial stage to prevent from environmental pollution.
The main purpose of this research study is to treat palm oil mill effluent by using electrocoagulation in order to. Palm Oil Mill Effluent Treatment Process Evaluation and Fate of Priority Components in an Open and Closed Digestion System Anwar Ahmad 1 * and Mohd. Z.

This generates an enormous Anaerobic Treatment Process 10 Comparison between Anaerobic and Aerobic. for Palm Oil Mill Effluent (POME) treatment and methane gas capture for renewable energy.
During In an anaerobic digestion process, the organic of the Serting Hilir Palm Oil Mill by using a pump. The POME was stored temporarily in the holding tank prior. Palm oil mill effluent, POME, palm oil effluent, palm oil slurry, palm oil sludge, POS, oil palm slurry, oil palm sludge, OPS, decanter cake the conversion of fresh palm oil mill effluent into a potential feedstuff now involves fermentation (anaerobic, thermophilic and Palm oil mill effluent - treatment and utilization.
In: Sastry CA. A method for the aerobic treatment of palm oil mill effluent (POME) was investigated in shake-flask experiments using a consortium developed from POME compost. Characteristics of POME Used in the Study.
The sedimentation process resulted in significant () “Anaerobic treatment of palm oil mill effluent in a two-stage up-flow anaerobic.
