    Abstract Surfactants have ability to mobilize the residual oil trapped in porous medium and resulting higher oil recovery by altering interfacial tension between residual oil and water. However, adsorption of surfactant onto the solid surface reduces the concentration of surfactant and makes it less effective in interfacial tension reduction in enhanced oil recovery (EOR) applications.

  • Flocculants: NSF, FDA And GRAS Approved Flocculants

    2018-5-11 · A series of novel amphoteric starch-based grafting flocculants, SCPAMPAA, have been successfully synthesized in this current work. The novel flocculants demonstrate high flocculation performance with low optimal dosage, wide flocculation window and low pH sensitivity in the removal of different types of colloidal contaminants with even opposite surface charges from water.

    Aims: In this study, the effect of the coagulation process on treatment of simulated dairy wastewater (SDW) was investigated using the mineral and organic coagulants. Materials and Methods: Different types of coagulants such as inorganic (Alum and ferrous sulphate) and polymeric coagulants (polyacrylamide [PAA] and polyferric sulphate [PFS]) were investigated.
