Electrocoagulation (EC) is an electrochemical technique which has been employed in the treatment of various kinds of wastewater. In this work the potential use of EC for the treatment of palm oil mill effluent (POME) was investigated. In a laboratory scale, POME from a factory site in Chumporn Province (Thailand) was subjected to EC using aluminum as electrodes and sodium chloride as supporting...

Two fungi (unidentified) were isolated from soil and marine environments. These isolates were used for bioremediation of pulp and paper mill effluent at the laboratory scale. The treatment resulted in the reduction of color, lignin, and COD of the effluent in the order of 78.6%, 79.0%, and 89.4% in 21 days. A major part of reductions in these parameters occurred within 5 days of the treatment, ...

In this experimental work the ozone action on the depuration of olive oil mill wastewater is studied for different operational conditions based on an actual industrial treatment plant. It was verified that the application of a Mn-Ce-O catalyst prepared at the laboratory, with a Mn/Ce molar proportion of 70/30, enhances the depuration efficiency and the effluent biodegradability. Ozonation opera...

A mesophilic, syntrophic, fatty-acid-oxidizing anaerobic strain, designated MPA(T), was isolated from granular sludge in a mesophilic upflow anaerobic sludge blanket reactor used to treat palm oil mill effluent. Cells were slightly curved, non-motile rods. Spore formation was not observed. The optimal temperature for growth was around 37 degrees C and optimal pH for growth was 7.0. Strain MPA(T...

Kaewchai, S. and Prasertsan, P. Screening and application of thermotolerant microorganisms and their flocculant for treatment of palm oil mill effluent Songklanakarin J. Sci. Technol., 2002, 24(3) : 413-420 Among fifteen thermotolerant polymer-producing isolates, three strains SM 29, WD 90, and SM 38 produced polymer posessing very high flocculating activities (24.81, 14.63 and 10.84, respectiv...
