This presentation will discuss the case study where a ceramic membrane retrofit was completed for a full scale (26.4 MGD) drinking water treatment plant based on proof of concept and process verification testing. This particular plant targeted iron, manganese and radium removal utilizing ultrafiltration as RO pretreatment. However, the system experienced several operational issues which led to optimization studies as well as an evaluation of alternative technologies. Laboratory testing and pilot testing were conducted at the site over a period of 6 months with flat sheet ceramic membranes. The data reflected stable operation with higher flux rates, reduced waste/sludge volumes, reduced maintenance and chemical cleaning, as well as reduced CIP cleanings. Based on the data, the customer began a retrofit from polymeric to ceramic membranes and finalized the retrofit by 2013.
