Filter backwash control system for a water or wastewater treatment system to conserve water during the filter backwash process

A method of treating water in a water treatment system filter having a water filter control process, comprising:

• obtaining benchmarking metrics to generate a filter tank turbidity setpoint and a filter media level setpoint, the method comprising:
• obtaining a filter media level electrical signal generated by a level device to measure a filter media level within a filter;
• obtaining a filter tank turbidity level signal generated by a backwash turbidity meter measuring a filter tank turbidity level from within a filter tank;
• obtaining a filter backwash flow rate signal generated by backwash flow meter measuring a filter backwash flow rate;
• applying data analytics, artificial intelligence, machine learning or neural network methodologies upon the signals to generate filter operational values comprising a filter media bed expansion setpoint and a backwash turbidity setpoint;
• and
• controlling a filter backwash process by, while monitoring filter backwash turbidity, sending one or more output signals that are used to control a backwash inlet liquid flow in order to maintain a filter media bed expansion setpoint, and stop the backwash inlet liquid flow when the filter backwash turbidity set point is reached.
