Abstract
A modular water treatment apparatus is provided for soft drink postmix dispensers. The apparatus includes a basic filter unit and additional modules selected from booster pump, UV treatment, and ion exchange modules as needed to match situs water problems determined water testing. A control module has microcontroller based circuitry which provides apparatus monitoring and control. Disabling and warning alarms are generated for predetermined apparatus conditions on a priority basis. A hand-held controller can be coupled to the control module to provide an operator interface for entry and readout of data on the basis of key entries.
Claims11
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;
- and
- a 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;
