Industrial liquids containing viscoelastic surfactant compositions can be reversibly thickened and broken. For example, a thickened industrial liquid can exhibit good solids carrying capacity, and after the viscosity of the liquid is broken, using techniques such as change in pH, addition of a hydrocarbon, change in temperature, etc., the solids can be easily removed therefrom. Viscosity can be again provided to the industrial liquid without the necessity of adding substantial amounts of additional thickener.
