Abstract
Systems and methods for managing effluent from recharging zirconium phosphate and/or zirconium oxide are provided. The systems and methods control the pH of the zirconium phosphate and zirconium oxide effluent to allow for safe disposal. The systems and methods provide for management of the recharger effluent pH while recharging zirconium phosphate and zirconium oxide either independently or concurrently.
Claims20
A sorbent recharger, comprising:
- at least a first receiving compartment for a first sorbent module;
- the first receiving compartment having a first sorbent module inlet and a first sorbent module outlet;
- a first inlet line fluidly connected to the first sorbent module inlet;
- a first effluent line fluidly connected to the first sorbent module outlet;
- a disinfectant source, a base source, a water source, and a brine source;
- wherein any one of one of the disinfectant source, base source, water source, brine source, and combinations thereof is fluidly connected to the first inlet line;
- and wherein at least one of the disinfectant source, base source, water source and brine source is fluidly connected to the first effluent line at a common reservoir or a junction with a static mixer at or downstream of the junction.
