The present invention relates to computer automated upflow bead filter systems. These systems typically include a bead bed; in situ sensors/transducers for monitoring dissolved oxygen, differential pressure across the filter, water flow, pH, oxidation-reduction potential or any combination of these; a control system, such as a computer, operably coupled to the in situ sensors/transducers; an influent conduit below the bead bed; and an effluent conduit above the bead bed. The in situ sensors/transducers convert monitored conditions to electrical signals and at least back washing or dissolved oxygen may be continually adjusted in accordance with the electrical signals using the control system. By virtue of the control system, water flow rate or residence time, backwash frequency, and backwash duration may be continually adjusted to optimize the operation of the filter.
