Abstract
Control logic and processes for monitoring and controlling sorbent rechargers are presented. The control logic and processes use control systems to monitor the rechargers for performance problems and to control the recharging process. Various sensors in communication with the control systems are provided to ensure proper operation.
Claims20
A sorbent recharger, comprising:
- a first receiving compartment for a first sorbent module;
- the 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;
- at least one of an disinfectant source, a brine source, a base source, and a water source fluidly connected to the first inlet line;
- at least a first pump positioned in the first inlet line for pumping fluid from the disinfectant source, brine source, and water source to the first sorbent module inlet;
- at least one flow sensor, at least one pressure sensor, at least one temperature sensor, and at least one conductivity sensor;
- and
- a control system in communication with at least one of the flow sensor, pressure sensor, temperature sensor or conductivity sensor;
- the control system for controlling the first pump.
7 more elements
A method, comprising the steps of:
- pumping fluid from an disinfectant source, a base source, a brine source, a water source, or combinations thereof, through a recharging flow path to a first sorbent module;
- and
- determining a presence of a leak, occlusion, pump failure, chemical mismatch, or chemical run-out.
