Abstract:
The present invention relates to an aquaponics system and method. There is provided an aquaponics system including a tank (10) for housing at least one aquatic animal species; a plant growing apparatus (18) for housing one or more plant species growing in an aqueous environment; and a biofilter module including a solids removal means (12) and a biological waste digestion unit (14) including a biological species for digesting solids to produce plant nutrients. Plant nutrients are transferred to the plant growing apparatus (18) and at least a portion of the water is returned to the tank (10).
Abstract:
The invention relates to a diffusor for adding of gases into water, said diffusor comprising a perforated tube (1) and at least one supply tube (2), said the at least one supply tube (2) is at one end coupled to a source for supplying gas and at the other end in fluid communication with the perforated tube (1), the gas is supplied to the perforated tube (1) through at least one inner supply tube (4; 5; 15) extending from the supply tube (2) to the perforated tube (1). The invention is distinctive in that at the least one inner supply tube (4; 5; 15) is a non-perforating tube and has at least one outlet (4a, 5a, 15a) situated at a free end of the at least one inner supply tube (4, 5, 15), said gas is adapted to be distributed into the perforated tube (1) through the at least one outlet (4a, 5a, 15a).
Abstract:
Die Erfindung betrifft ein Verfahren zur Aufbereitung zirkulierenden Wassers in Kreislaufanlagen, insbesondere in rezirkulierenden Systemen für Aquakulturen, wobei zumindest ein Teilstrom des zirkulierenden Wassers über zumindest einen Bypass geleitet und in dem Bypass mittels zumindest einer Ultra- und/oder Mikrofiltration aufbereitet und nach der Ultra- und/oder Mikrofiltration in das zirkulierende Wasser zurück geleitet wird, wobei die Steuerung des Massenstromes des Teilstromes in Abhängigkeit eines oder mehrerer für die Wasserqualität des zirkulierende Wassers charakteristischen Parameters erfolgt.
Abstract:
The present disclosure relates, according to some embodiments, to systems and methods for processing organic compounds, such as manure or other organic waste. Embodiments may comprise a first containment chamber, a first anaerobic chamber, and a second anaerobic chamber. A first anaerobic chamber may receive organic compounds from a first containment chamber, and may provide a fluid stream to a second anaerobic chamber. The second anaerobic chamber may comprise a substrate, such as lava rock, with bacteria growing thereon. Further, a sulfide gas treating unit may receive and treat sulfide gases from a first anaerobic chamber and/or a second anaerobic chamber. A water storage unit may receive and store waste water or effluent from a first anaerobic chamber and/or a second anaerobic chamber.
Abstract:
A process for treating wastewater from livestock industry, comprising subsequently admixing two different types of nitrogen-containing cationic polymers into the treated livestock industrial wastewater, wherein said polymers comprise polydiallyldimethylammonium chloride (PDAC) and cationic polyacrylamide (CPA).
Abstract:
Method for the treatment of animal waste from an animal containment building, comprising: a) periodically removing undiluted animal waste from the animal containment building; b) placing the removed waste in a hydrolytic degritting chamber with heated water or steam to obtain a mixture having a temperature of at least about 50 degrees C to about 60 degrees C, and degritting the mixture; c) transfer of at least a portion of the degritted mixture into an anaerobic digester chamber held at a temperature of about 50 degrees C to about 60 degrees C, and digesting the mixture; and d) transfer of at least a portion of the digested mixture to a secondary solid-phase digester chamber loaded with dry biomass and fermenting the mixture at a temperature of at least about 50 degrees C, to obtain bio-organic fertilizer and biogas. A system for the treatment of animal waste from one or more animal containment building, comprising: a) one or more animal containment buildings containing animal waste; b) a hydrolytic degritting chamber in fluid communication with an anaerobic digester chamber, which is in turn in fluid communication with a secondary solid-phase digester chamber, all in an insulated unitary structure wherein communication is accomplished by flow pressure; and c) heated water or steam to combine with animal waste from the one or more containment buildings to raise the combined temperature to about 50 degrees C to about 60 degrees C; wherein in use the animal waste from the animal containment building is in fluid communication with the hydrolytic degritter. The method and system for disposing of waste for the hog industry avoids use of lagoons.
