Abstract
A system includes a recirculation line, a mainline flow meter operable to measure a flowrate of fluid flowing through the recirculation line, a mixing chamber, an inlet line coupled between the recirculation line and the mixing chamber, at least one chemical injection port coupled to the inlet line, a dedicated feed pump operably associated with each chemical injection port, and an outlet line coupled between the mixing chamber and the recirculation line. The mixing chamber includes a plurality of mixing zones, a mixing blade assembly that includes at least one blade within each mixing zone, and a motor coupled to the mixing blade assembly and operable to rotate the mixing blade assembly. Each of the dedicated feed pumps is coupled to a separate chemical supply and is operable to pump a chemical to the corresponding chemical injection port for injection into the inlet line.
