ESI was the engineer and construction manager for the installation of a new 1300 gpm countercurrent fluidized bed demineralization system. This facility utilizes state-of-the-art technology to minimize the operating cost while providing the purest water available. Raw water is supplied to the demineralizer plant from a storage tank via forwarding pumps. Water flows from the cation to the decarbonator and into the anion units before finishing in the demineralizer water storage tank. From here, demineralizer water pumps supply treated water to the process. This system replaced the existing hot lime water treatment system which treated water for the entire facility.
