A research study was carried out aiming to investigate the possibility of treatment of vegetation water in a anaerobic digester like a sanitary landfill. This vegetation water originates from olive oil production. The results, obtained from lysimeters filled with Municipal Solid Waste, show very high gasification and reduction of the organic load of vegetation water, with no inhibitory effect on waste degradation processes providing the vegetation water is added to an active methanogenic system or buffering the landfill system during the acid phase. The inhibitory influence of compounds, like polyphenols, which can be present in vegetation water in large amounts, has been studied.

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.

AbstractThe aim of our research was to evaluate treatment efficiency of Fenton’s process and ozonation for the treatment of two landfill leachates (fresh and mature), both resulting from municipal waste disposal. Both samples had high organic load (COD of the fresh and mature landfill leachate were 2700 and 490 mg·L

Activated Persulfate

Complex wastewater matrices present a major environmental concern. Besides the biodegradable organics, they may contain a great variety of toxic chemicals, heavy metals, and other xenobiotics. The electrochemically activated persulfate process, an efficient way to generate sulfate radicals, has been widely applied to the degradation of such complex effluents with very good results. This review presents the fundamentals of the electro-persulfate processes, highlighting the advantages and limitations, followed by an exhaustive evaluation on the application of this process for the treatment of complex industrial effluents. An overview of the main relevant experimental parameters/details and their influence on the organic load removal is presented and discussed, having in mind the application of these technologies at an industrial scale. Finally, the future perspectives for the application of the electro-persulfate processes in the treatment of complex wastewater matrices is outlined.
