Ceramic membrane is a proven technology to recycle O&G produced water as well as tailing pond effluent from the mining industry. Several case studies will be detailed. A 50,000 bpd produced water reclamation facility has been in operation since 2012 using CeraMem membranes. A Lithium mine in Australia selected CeraMem to treat a 150 m3/h tailing pond effluent following a pilot study.
