Abstract: A sand filter controller for monitoring and controlling an operation of a sand filter is provided. The sand filter controller includes a microcontroller that receives information about an operation of the sand filter from sensors installed in the sand filter, electrical relays that control air operated valves (AOVs) of the sand filter based on signals from the microcontroller, a liquid crystal display (LCD) screen connected to the microcontroller and that displays the operation of the sand filter, a position of each of the electrical relays, and a position of each of the AOVs, and a power supply that powers the microcontroller, the electrical relays, and the LCD screen. The sand filter is a single-housing-multi-stage water treatment sand filter.

Abstract: A system includes a sand filter disposed within a tank. A pipe connected to the tank is configured to flow fluid in or out of the tank. The system includes a valve configured to selectively allow fluid to flow through the pipe and a flowmeter configured to measure a flow rate of fluid through the pipe. An automatic control unit includes one or more processors and a non-transitory computer readable medium storing instructions executable by the one or more processors to perform operations including determining a debris accumulation status for the sand filter based in part on flow measurements from the flowmeter, and determining a failure status of the valve based in part on flow measurements from the flowmeter.
