Since 2015 ceramic membranes have been in continuous use in dewatering MF and UF membrane concentrate to achieve Zero Liquid Discharge (ZLD). In this case study for DOC and Fe, removal of the Sludge with 20% solids is produced automatically on demand without consumables or labor of any kind. The recovered water is sent directly to the clear well. T...

The presentation will cover four topics. First, the author will discuss the features and basic differences between polymeric and ceramic membranes. The second topic will be a brief history of ceramic membranes, tracing the history from the 1st generation to the current (i.e., 5th) generation membranes that were developed and are produced and mark...

A pilot study was conducted in Texas on surface water from the Rio Grande for a Multi MGD drinking water application. Water was drawn directly from the reservoir and sent to the cross flow ceramic membrane process. No coagulation, flocculation, settling or other pretreatments were applied upstream of the membrane process. This presentation will foc...
