Abstract
Compositions and methods and systems for treating wastewater within a wastewater treatment system of described. In an embodiment, a method for treating wastewater may include adding a magnesium compound to wastewater within a wastewater treatment system. The method may also include adding an effective amount of a dispersing agent and one or more of a free magnesium control agent and a seed material to wastewater within the wastewater treatment system to control the formation of struvite scale within the wastewater treatment system. Other compositions and methods are described.
Claims22
A method for treating wastewater comprising:
- adding a magnesium compound to wastewater within a wastewater treatment system, the wastewater treatment system including a municipal wastewater treatment system;
- and
- adding an effective amount of a dispersing agent, the dispersing agent including one or more polymeric surfactants, and a free magnesium control agent, wherein the free magnesium control agent is selected from the group consisting of one or more of a salt of a polyamine acetic acid, an acid of a polyamine acetic acid, an oxylate, a gluconate, a carboxylate polymer, and a polyaspartic acid, to the wastewater within the wastewater treatment system to reduce the formation of struvite scale within the wastewater treatment system.
