✦ Synopsis

Two materials of different structure, sepiolite and bentonite, evaluated as supports for the microorganisms effecting anaerobic fermentation, behaved differently towards condensation water from thermally concentrated olive mill wastewater from a kinetic point of view. Assuming the overall anaerobic digestion process to conform to first-order kinetics, the apparent kinetic constant for the digester including sepiolite as support was 1.12 day 1, while that of the digester using the bentonite support was 0.73 day -1. Thus, the apparent kinetic constant of the process was increased by 35 % with the use of sepiolite. 'The yield coefficient, Yp/s, was 0.344 and 0.318 litres CH 4 STP/g COD for the sepiolite and bentonite supports respectively.
