The SDOX-CS from BlueInGreen is used to supersaturate lines (both gravity and force main) with oxygen. Keeping a sufficient amount of oxygen in the line keeps sulfides from coming out of the solution. Oxygenating a line reduces odor and corrosion, and the wastewater receives pretreatment before entering the treatment facility. It is skid mounted, factory tested and ready for piping in and out. It can run off of liquid oxygen dewars or be used with oxygen generators. 479/527-6378; www.blueingreen.com.
