Wastewaters fed to reverse osmosis (RO) membranes sometimes need to be acidified to prevent inorganic fouling and increase total ammoniacal nitrogen (TAN) retention. In this project, the effect of pH level (6.5–7.1) and acid type (HCl vs. H2SO4) on

There is an increased interest in the application of reverse osmosis (RO) technology to treat agricultural wastewaters because RO membranes can produce reusable water and recover valuable nutrients. With highly charged wastewater, however, membrane r

Anaerobic sequencing batch reactors (ASBRs) treating slaughterhouse wastewater at 20 °C were subjected to soluble organic, particulate organic and hydraulic shock loads. The normal organic loading rate (OLR) was increased by a factor ranging from 1.
