The PAM1 treatments resulted in 0.5 mg L(-1) drain water polyacrylamide concentrations 1.6 km downstream of PAM addition, while PAM5 and PAM10 treatments produced > 2 mg L(-1) drain water polyacrylamide concentrations. We concluded that, although PAM practically eliminates Imperial Valley tailwater sediment loads, it does not effectively reduce

Nonionic surfactants are superior over ionic surfactants in many respects. Therefore, their industrial application have been quite widespread in the past century. In 1964, 105 T of nonionic surfactants were produced and the production grew in the 1990s to more than 105 T per year.
