  • What is water soluble polyacrylamide (PAM)?
  • 1. Introduction Water-soluble polyacrylamide (PAM) is used in various industries as a displacement agent, drilling mud additive, and sewage treatment agent (Bao et al., 2010, Sojka et al., 2007). It is also widely used in the oil recovery industry in China, resulting in large amounts of PAM-polluted wastewater.
  • What is copper containing wastewater (CCW)?
  • Copper-containing wastewater (CCW) is one of the most harmful heavy metal-laden wastewater that is produced in the mining, metallurgy, chemical manufacturing, iron and steel, printed circuit, electroplating, paint, and fertilizer industries . China is a populous country with the largest sewage discharge in the world.
  • What is high molecular weight polyacrylamide (PAM)?
  • Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
  • Can improved membrane remove copper from high-concentration mixed wastewater?
  • However, based on the continuous research on membranes and associated improvements, the improved membrane method can selectively remove copper from high-concentration mixed wastewater in a stable manner; among improved membranes, liquid membranes are being widely studied due to their superior properties. 3.2.
