Low-Cost Ceramic Membranes Manufacture for MBR: Comparison of Pilot and Industrial Scale
The objective of this study is to manufacture ceramic membranes with lower cost than the commercial ceramic ones, more sustainable and competitive. Tewari et al. (2010) evaluated the efficiency of low cost ceramic membranes at laboratory scale. The membranes developed are made from agricultural and industrial wastes, such as olive stones (from olive oil production) used as a pore former, marble powder and chamotte (from fired tile scrap). Different formulations have been compared to achieve the adequate plasticity of the mixture and permeability of the membrane. The properties of the ceramic membrane are mainly determined by their composition, particle size of the pore former and sintering temperature. The membranes are being validated at pilot scale in the university and at industrial scale in an MBR located in Aledo WWTP (Murcia, Spain).
