ABSTRACT:
A water filter system comprising a control system, communication means, piping, actuators, sensors and valves. The control system utilizes a communication bus for controlling and monitoring water flow through the piping via control of the actuators and valves. The communication bus comprises a two-wire network in a loop configuration coupling the various actuators and valves to the control system. The control system includes a display and programmable control logic for monitoring and controlling the actuators and valves. In one embodiment, the communication bus adheres to a Actuator Sensor-Interface (AS-I) standard. The control system is further coupled to other control systems in a water treatment plant and a Supervisory Control and Data Acquisition (SCADA) network.
