Abstract:
A water treatment apparatus having a conduit forming a flow path for water being treated, the apparatus comprising;a booster pump connected to the flow path;a filer module connected in the flow path;a pressure sensor coupled to the flow path;a flow sensor coupled to the flow path;an ion exchange chamber connected in the flow path; anda monitoring and control system responding to an output from the pressure sensor to provide ON/OFF cycling control of the booster pump for outlet water pressure control;the monitoring and control system further responding to an output from the flow sensor to determine total flow over time;the monitoring and control system generating a filter replacement alarm when a low water pressure setpoint is detected and an ion-exchange-resin replacement alarm when a setpoint total water flow is reached;the monitoring and control system including a first microcontroller system for storing control and process data, for processing feedback data from the sensors, for generating ON/OFF control commands to the booster pump, and for tracking elapsed time from filter and ion exchange chamber installation; andthe first microcontroller system storing a table of alarms classified as disabling or warning for display and/or readout, the alarms being listed in the table according to predetermined priorities to facilitate clearing of activated alarms.
