Specializing in dissolved air flotation (DAF) water treatment systems. We offer both new and used Krofta DAF water clarifiers. DAF technology as an alternative to conventional water treatment processes. DAF is a fast and highly efficient method for removing turbidity, color, suspended solids and other contaminants from water using air bubbles. These specially created air bubbles are first mixed with wastewater, attach themselves to solids present and then separate them by flotation leaving clarified water behind. DAF has become widely accepted for use in potable water treatment, municipal wastewater as well as a variety of industrial applications.
