When we varied the oasis waste concentration from 8% to 15% (figure XX), at a sintering temperature of 800°C and molding pressure of 8 bars, we showshowed a sharp increase in the open porosity of the prepared ceramic membrane, from 23.41% to 40.05%. For this same evolution of oasis waste, we remarknote a small variation of thein closed porosity. After, there was no effect of adding oasis waste to the solid phase of the ceramic membrane on open porosity but an increase of closed porosity can be observed. In this case, the oasis waste was combined in aggregates, and the number of aggregates increases whitwith the increase ofin the percentage of oasis waste. percentage. AfterFollowing combustion, these aggregates lead to a closed porosity.
