✦ Synopsis

The high organic content of Olive MiU Wastewaters (OMW) causes some difficulties in maintaining the anaerobic process efficiency at high level. The two phase anaerobic system was used to treat olive mill wastewaters, diluted with tap water. Phase separation was accomplished through control of the hydraulic retention time and initial COD removal in two reactors operated in series. The effect of substrate concentration and phase separation on ~emoval efficiency has been investigated. Experimental results indicated that yield of 0.322 to 0,335 litre biogas/gCOD removal were obtained with two phase anaerobic treatment and space loading rate of 2.3 and 2.4 gCOD/t.day. The maximum methane production rate near to the theoretical value and corresponded to 360 mt ofCH 4 for 1 g COD removal.
