ABSTRACT:
A non-toxic waste water treatment composition is provided. The waste water treatment composition is formed from: (a) an alkanolamide; (b) an ethoxylated alkylphenol, ethoxylated aryl phenol, or combination thereof; (c) a first surfactant selected from the group consisting of: an ethoxylated alcohol, a glycerol ester, a propoxylated fatty acid, an ethoxylated fatty acid, a propoxylated alcohol, an ethoxylated alcohol, a propoxylated alkyl phenol, an ethoxylated alkyl phenol, and a combination thereof; (d) a second surfactant selected from the group consisting of: a sulfosuccinate, a sulfosuccinate derivative, an imidazoline, an imidazoline derivative, and a combination thereof; and (e) optionally, a foaming agent. Methods for forming the non-toxic composition and for treating waste water with the composition are also provided. Finally an apparatus for introducing a waste water treatment composition into a waste water system is provided. The apparatus includes tubing for delivering the waste water treatment composition to at least one spray nozzle and a swivel fitting connecting the tubing to the spray nozzle. The spray nozzle is configured to deliver the waste water treatment composition into the waste water system, and the swivel fitting permits 360 degree rotation of the spray nozzle around the tubing.
