Abstract: A process water filtration system includes a vessel (12) containing filter media units (14). Water jets (30 and 32) create movement of the filter media units (14).

Abstract: The present invention relates to a filtration system for purifying water, in particular aquaculture water. Furthermore, the invention relates to a method of purifying water wherein water is supplied to a filtration system, comprising filtration medium for filtering water and a grid for preventing water channeling within the filter wherein said grid comprises means for allowing passage of said filtration medium through the grid, and a water recirculation system for purifying contaminated water from aquaculture and recirculating purified water to the aquaculture.

Abstract: A water recirculating system for use in producing fish. The water recirculating system includes a fish raising tank that provides an environment for fish to grow and a supply system to deliver contaminated water from the fish raising tank to a filtration system. The filtration system includes a chamber with a hydraulic loading area that is divided into a plurality of cells with smaller hydraulic loading areas. Filter media is positioned in each cell to filter the contaminated water received from the fish raising tank. A delivery system returns the filtered water back to the fish raising tank.

Abstract: A method for controlling environmental conditions or variables to which living organisms are exposed employs time integrated variables (TIVs) to assist in controlling the conditions. In one example, temperature in a poultry house is controlled, in part, according to a 24 hour time integrated average temperature value. Since it has been established that poultry is more sensitive to a 24 hour time integrated average temperature than to a particular instantaneous temperature, a temperature control strategy based upon the 24 hour time integrated average temperature can result in optimum performance of the poultry resulting in a substantial economic benefit. Further, in some instances the instantaneous temperature may be allowed to fluctuate over a wider range of temperatures, as long as the time integrated average temperature value is maintained within a desired range, and this can provide additional economic benefit from reduced operating expenses of the environmental control system.

Abstract: The present invention is directed to a closed cycle aquaculture system for fish rearing which includes as part of a water treatment subsystem a rotating biological contactor. The contactor nitrifies the contaminated water to remove toxic materials therefrom and also can be operated to maintain the temperature of the water near the wet-bulb temperature of the surrounding air when desirable.

Abstract: Egg products, such as deviled eggs, are prepared by an easily automatable method starting with separate quantities of raw egg whites and egg yolks. The uncooked egg whites are mixed and evacuated to remove air and other gases, then dispensed into a multiplicity of open molds which preferably are of the size and shape of half an egg. Egg yolk filling is prepared from raw egg yolks which are cooked, chopped, and blended with seasonings. Most usually, a fraction of the total egg yolk filling is dispensed to float on the uncooked egg white in the molds. The egg white with egg yolk filling floating on top is cooked in steam and then a further amount of egg yolk filling is mounded on top to yield the desired egg product, e.g., a deviled egg. The cooking molds can be a portion of the final marketing package.

Abstract: Method and apparatus for controlling environmental conditions in an animal house, and particularly in a poultry house, for producing maximum economic return. The static parameters of the house are determined, and thereafter continuous measurements are made of current inside and outside temperatures. The operator makes periodic assessments of litter condition in the house, and adjusts the target 24-hour average relative humidity to produce the desired litter condition. The system controls the heating and ventilation system to obtain the desired 24-hour average relative humidity while maintaining the optimum temperature conditions in the house for maximum economic return.
