Palm Oil Mill

Palm oil mill effluent (POME) pollution is a serious issue that has gained the attention of an international audience including policy makers, mill owners, NGOs and academicians. With a production rate of 74 million metric tonnes a year, Malaysia is in dire need for new technologies able to address this mounting problem. While previous research has attempted to modify existing microbial driven organic degradation methods to optimize the organic load removal, new studies recognize the futility in this endeavour as mills are unwilling to change the way they operate and adopt these disruptive technologies. Instead current research aims at tertiary polishing technologies of which photocatalysis has emerged as a forerunner. Recent advances indicate photocatalytic treatment of POME is a viable solution to the problem but for it to be cost effective, future studies should focus on visible light driven processes and new reactor configurations to improve the photocatalytic activity of existing systems.

Anaerobic Pretreatment

The palm oil industry is one of the major agro-based industries in Malaysia whose production accounts for more than 90% of the world export. The industry, however, also generates enormous quantities of liquid waste with high organic load causing serious pollution problems. In view of the high level of organics, anaerobic pretreatment is usually practised prior to aerobic breakdown. Most of the anaerobic digesters installed at the mills are currently operated under mesophilic conditions. However, the inherently high temperature of the effluent suggests that thermophilic digestion would bring about a much more effective system. This paper reports on results obtained from a pilot plant study on thermophilic anaerobic contact digestion of palm oil mill effluent which has been conducted and includes a microbiological study associated with the investigation.

Research about influence the addition of trace metal Fe against allowance for the solid content of palm oil mill effluent using Hybrid Upflow Anaerobic Sludge Blanket Reactor aim to know the additionof trace metal Fe against allowance for the solid content of palm oil mill effluent using HUASB reactor based on removal of Chemical Oxygen Demand (COD), Total Suspended Solid (TSS) dan Volatile Suspended Solid (VSS). The reactor isa reactor with a combination of suspended growth reactor in the bottom and attached growth reactor at the top. The material used is palm oil mill effluent and inoculum derived from PKS Pagar Merbau. Test parameters to observed are COD, TSS and VSS. The optimum conditions obtained on the organic load is 17024 mg/l with the addition of Fe is 0.5 mg/l so that obtained COD reduction is 85.891%, TSS reduction is 86.047% and VSS reduction is 36.566%.

The Impact

Background: Raw palm oil mill effluent is toxic effluent capable of posing serious threat to plants when discharged to the environment. In developing countries, the untreated effluent is often discharged to the surrounding land due to high cost associated with its treatment. The aim of the current study was to evaluate the impact of palm oil mill effluent treated with locally available material on the growth of maize. Methods: The bunch ash obtained from local material by burning de-fruited oil palm bunch was used for the treatment. The experiment was consisted of eight treatments of concentrations of palm oil mill effluent viz 1.0%, 2.0%, 3.0%, 4.0%, 5.0%, 6.0%, 7.0% and 8.0%. The treatment was carried out on potted maize plants with six replications. Four kilograms of soil was weighed into each pot. Six pots were labelled as control, with untreated palm oil mill effluent added to them. Eight other groups consisting of six pots each were treated with 1.0%, 2.0%, 3.0%, 4.0%, 5.0%, 6.0%, 7.0% and 8.0% concentrations of the effluent. The maize seeds were planted one in each pot to avoid overcrowding. The pots were transferred to greenhouse and each pot was moistened daily with the specified concentration of the palm oil mill effluent. The growth rate, plant height and leaf length of the maize plants were thereafter determined. Result: The 8.0% concentration of bunch ash in the effluent had the highest expected effect on all the parameters whereas the control gave the lowest expected effect. The effects increased as the concentration of bunch ash in the effluent increased, indicating that increased concentration of bunch ash recorded significant increase in growth rate, height and leaf length of maize. The analysis of variance for the obtained data showed that the effects of the different concentrations were significantly different. This study provides an alternative and cost effective method of ameliorating the toxicity of palm oil mill effluent to plants.
