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

This study investigated the effects of polymer charge density (CD) and molecular weight (MW) on the efficiency of solid-liquid separation of swine manure at various dry matter (DM) contents. Flocculated manures were filtered through 1 mm screens. The

Four pretreatments to hydrolyse and/or reduce the size of fat particles in slaughterhouse wastewater (SHW) were tested: sodium hydroxide and three lipases of plant, bacterial and animal (pancreatic) origin. Hydrolysing agents and SHW containing betwe
