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.

Automated closed recirculating aquaculture filtration system

The present invention is an automated aquaculture system which comprises: one or more culture tanks connected to a closed system of filters and ultraviolet or ozone sources for water purification prior to returning water to the culture tanks. Also disclosed as part of the system are automated biofilters that automatically monitor water conditions in the system, and video cameras in the tanks that monitor growth and condition of the animals in the tank. This invention is also a process useful for culturing an aquatic species, using the disclosed systems. Preferred species include shrimp, squid, marine fishes and fingerlings and marine mollusks.

Process for exciting, attracting, stimulating, and/or inciting members

A process and system for the reduction of nitrate to nitrogen in a fluid medium. Anaerobic bacteria fed by a carbon source are used for nitrate reduction. The addition rate of the carbon source and process residence time are controlled using the oxidation-reduction potential of the fluid medium to achieve a desired level of nitrate reduction. An industrial process control system may be used to monitor inputs and control outputs. A column of suspended beads may be used as the anaerobic bacterial bed for denitrification.
