Disclosed an aerobic system for decomposition of aqueous organic waste, which comprises at least a first processing container including sides, an upper opening, a substantially horizontal floor, an inlet, an outlet, at least one channel arranged at the floor having an upwardly opening mouth, a ventilating pipe extending above the mouth, and a pump connected to the pipe and arranged to provide a supply of a gas to the ventilating pipe.

A water filtration system and corresponding method for removing particulate waste and biochemical waste from water is provided. The system includes a first compartment containing algae in liquid suspension. The algae is usable to agglomerate to the particulate waste and biochemical waste to form algal particulates in the water. The water and agglomerated algal particulates are provided to a second compartment through a fluid transfer conduit. The second compartment includes a set of suspension assemblies, each of the suspension assemblies contain bivalves usable to siphon the algal particulates from the water.

A water treatment system for a water reservoir comprises a collection box; a rotary drum filter arranged to receive gravity flow from the collection box through a receiving line; a primary bio-filter; a secondary bio-filter; one or more connecting lines originating at the rotary drum filter and comprising at least a first outlet line connected to the primary bio-filter and a second outlet line connected to the secondary bio-filter, the second outlet line comprising a pump; and a return line originating at the primary bio-filter and terminating at the water reservoir. The collection box has a bottom and sides defining an interior volume, and comprises a first water intake having a first riser; a second water intake having a second riser; and a third water intake having a third riser, each riser being disposed inside the interior volume and extend upwardly from the bottom of the collection box.

A system for indoor shrimp aquaculture is described that comprises a plurality of stacked raceways, each raceway being a long, flat rectangular tank comprising at least two sections arranged in series and scaled to accommodate shrimp of increasing size. The sections are separated by a moveable section divider whereby shrimp may be transferred between sections once they reach a predetermined size by opening the moveable section divider and allowing the shrimp and water to flow through into the next section. Each raceway includes a waste collection assembly situated at the downstream end of each section for collecting waste for removal. Methods of using the system to grow shrimp are also provided. The raceways are further adapted to facilitate operation of the production module at large scales, in this way; the system is scaleable to achieve high-throughput production of shrimp.

An algae preventive device for prevention of algae buildup in an aquarium is presented. The algae preventive device is useful for eliminating algae growth on all surfaces. Also, the algae preventive device is useful for keeping water clear and can be used on ponds, pools and aquariums. The algae preventive device does not impact fish or plant life and does not require testing of water, high-grade filers and media, lighting modification or chemicals.
