Recovery of Organic Acid from Wastewater - Synder Filtration
Recovery of Organic Acid from Wastewater - Synder Filtration

The recovery of organic acids from wastewater involves the use of, membrane filtration technology, to concentrate and recover volatile fatty acids. Once microfiltration and ultrafiltration membranes are employed to clarify and fractionate the suspended solids, nanofiltration can be used to desalt and concentrate the organic acids.
