Abstract: An efficient and economical wastewater treatment system is disclosed. The wastewater treatment system may comprise a first sump for receiving wastewater to be treated. The first sump includes a ring that acts a first focal point to gather the waste and remove solids. Suspended solids are transported from the first sump, through one or more filters, and sent to a second sump. The second sump is preferably in communication with one or more protein skimmers. The second sump preferably includes one or more secondary focal points for gathering suspended solids to be further treated by the one or more protein skimmers. The second sump may include a partition wall that separates the second sump into a main tank and a gathering tank. One or more collecting chambers may be disposed in the gathering tank. Inlet conduits disposed within the main tank create a cross-flow or horizontal vortex that forces water to cascade over the partition wall into the one or more collecting chambers.

Abstract: A food processing system is disclosed including a cooker including a first conveyor wherein food is cooked, a first chiller including a second conveyor wherein the food is chilled, a second chiller including a third conveyor wherein food is chilled, and a variable speed controller that controls the third conveyor to run at a different speed from the first conveyor. The first conveyor and the second conveyor preferably run at a same speed. The first chiller and the second chiller may be in fluid communication. In other aspects, the system further includes holes that allow the fluid to pass between the first chiller and the second chiller and flaps over the holes. The variable speed controller preferably ensures that the food exits the system with a pre-determined level of chilling, water weight, or both. Also, associated methods are disclosed.

Abstract: A tank system and a method for accommodating aquatic life and particularly fish. The tank system comprises a holding tank for holding fluid to sustain aquatic life disposed therein and a filtering means in the form of a biofilter for receiving extraneous fluid from the top of the holding tank at one side thereof separated from the biofilter by a partition. A tank discharge means comprising a longitudinally extending lip surmounts the partition to permit the discharge and passage of extraneous fluid from the top of the holding tank via a prefilter to a filtering area in which the biofilter is disposed. Recirculating means including a network of pipes is provided for recirculating the extraneous fluid passed through biofilter by gravity, from the bottom of the filtering area back to the holding tank via one or pumps and a pair of water inlet lines.

Abstract: An improvement in a fractionation/flotation system for removing waste such as biosolids, nitrates or nitrites from a liquid containing same and an apparatus for separating liquid containing particles of varying mass or specific gravity. A reactor vessel 153 comprises a fractionation column 153a and a foam aggregation chamber 153b surmounting the column. Liquid containing the waste is pumped into the fractionation column 153a via a pump 105 and an outlet 159 that branches into a first inlet 163 and a second inlet 165. These inlets inject liquid into the fractionation chamber 153a at intermediate locations that are axially spaced apart, where the first inlet entry 163a is higher than the second inlet entry 165a. A waste reducing gas such as air, oxygen or ozone is injected into the second inlet immediately prior to insetting the liquid into the fractionation column 153a. Foam generated from the inlet liquid has biosolids adsorbed thereto and is collected within the aggregation chamber 153b for extraction.
