March 2013 Emerging Technologies Solids Removal updated 2012 Technology Summary Nanofiltration (NF) and Reverse Osmosis (RO) (continued) Comparison to Established Technologies: Microfiltration and ultrafiltration membranes are used for membrane bioreactors where the membrane is in direct contact with the high solids mixed liquor. These membranes provide excellent removal of particulate and colloidal material but cannot remove dissolved constituents as can NF and RO. NF and RO remove total suspended solids, total dissolved solids, and other pathogens better than the ultrafiltration process. Available Cost Information: Approximate Capital Cost: Not available. Approximate O&M Costs: Not available.
