MPs then enter the wastewater treatment plants (WWTPs) from domestic, municipal, and industrial wastewater. Primary, secondary, and tertiary units are the main stages for the treatment of wastewater. Large solids in the wastewater are settled at the bottom of the primary tank via sedimentation forming primary sludge (PS).

Polymer (anionic polyacrylamide, APAM) flooding produced wastewater has a relatively high degree of mineralization and abundant ionic species. A comprehensive and systematic investigation of the influence of ion identity on APAM-induced membrane fouling is extremely necessary but has not been conducted to date.

The lack of information from column studies of Cu2+ transport in polyaluminium chloride and anionic polyacrylamide water treatment residuals (PAC-APAM WTRs) has been hampering their reuse as a media in stormwater bioretention systems. The transport behavior of inactive tracer Br? and Cu2+ in various systems with and without the presence of Pb2+, Cd2+, and Zn2+ was investigated in the columns ...

Preparation of RGO and Anionic Polyacrylamide Composites for Removal of

Abstract Graphene oxide (GO) have been reported as adsorbent materials, because its surface contains a large number of oxygen-containing groups, which provide masses of active sites. Nevertheless, it is difficult to separate GO from aqueous solution by conventional means after the end of the adsorption process.
