The air flotation of an emulsion of natural crude oil in water was studied to determine the factors that influence polyelectrolyte flotation aid performance. The polyelectrolytes used were commercial TFL 383 and its experimental analog C-20, both polymeric tertiary amines of the same molecular weight which differed only in degree of quaternization and therefore, in charge density. Polyelectrolyte-induced acceleration of oily waste water clarification, a first-order process, increased with ionic strength to a maximum of about 40-fold at ionic strengths that encouraged polyelectrolyte precipitation. The selection of flotation aids with consideration of the ionic strength of the waste water, or possible adjustment of the ionic strength of the waste water, are discussed.
