  • Patent number: 8252183
    Abstract: An exemplary method of treating nitrogen-contaminated wastewaters, especially those with high ammonia concentrations, according to the invention includes the steps of ammonia degassing and recapture, and of nutrient assimilation with microalgae. Organic nitrogen, organic carbon, phosphorus, heavy metals and other compounds may also be removed in different embodiments of the invention. Examples of applicable wastewaters include landfill leachate, municipal solid waste anaerobic digester effluent, agricultural anaerobic digester effluent, municipal wastewaters, agricultural wastewaters, and other similarly contaminated wastewaters.

  • Patent number: 6932025
    Abstract: A scalable fish rearing raceway system is provided, incorporating a fish containment structure having two semi-circular end sections, and two or more parallel fish raceways, surrounding a central zone for housing water treatment systems and a secondary fish crop. Heavy particulates are eliminated from the main fish rearing channels by use of conical areas located at either end of the parallel elongated raceways. Continuous removal of dead or dying fish from the raceway is accomplished by means of a floating mortality catcher consisting of a screened ramp at the surface of the cones which continuously collect moribund and dead fish. Grading bars separate and move fish underwater to an adjacent raceway through a common fish transfer channel. This larger scalable fish production system substantially reduces the direct labor and capital costs associated with the production of fish as compared with conventional circular fish rearing tanks.

  • Patent number: 6447681
    Abstract: An aquaculture wastewater treatment system is provided including three wastewater treatment subsystems. The first subsystem is comprised of a fish raceway solids removal channel populated with relatively high densities of a detritivorous fish such as tilapia and/or carp, that have high potential as an efficient means of feeding on, and thereby, removing suspended solids and particulate matter that are present in the primary fish production effluent. The second wastewater treatment subsystem is comprised of an enhanced form of nitrifying reactor termed the Suspended Media Ammonia Removal Technology (SMART) biofilter reactor subsystem. This water treatment component consists of an open ditch bioreactor oxidation vessel in which water is circulated by means of one or more powered paddlewheels.
