A decoupled aquaponic system having two loop subsystems: hydroponic (Hp-loop) (2) and aquaculture (RAS) (1) interconnected by a third loop subsystem performing reverse osmosis filtration (OI) of RAS (1) recirculation water to achieve a higher nutrient quantity in the former and higher quality recycled water in the latter, with consequent energy savings due to its variable control structure and OI membrane effectiveness. Prior to entering the system containing the OI membrane, a water ultrafiltration (UF) (22) treatment is added to preserve its lifespan.

A salt separator separates salts and/or solid materials from a pumpable aqueous fluid mixture under process conditions, which lie in the range of the critical point for the fluid mixture. The salt separator contains a reaction zone in a cavity for transforming the pumpable aqueous fluid mixture into a raw mixture, e.g. a methanation reaction, and a feed opening for the pumpable aqueous fluid mixture to the cavity. The feed opening is realized in a rising pipe that protrudes into the cavity. A first extraction opening is provided for the raw mixture freed of salts and/or solid materials. The first extraction opening is arranged in the upper region of the cavity and a second extraction opening is provided for a brine containing the salt and/or the solid materials. The second extraction opening is arranged in the lower region of the cavity and is located lower down than the feed opening.

This invention describes the equipment and a method to recover starch from a dilute starch stream produced by manufacturing facilities which process the starch-containing materials, such as potato and corn. The process comprises feeding a dilute aqueous slurry of less than about 5% by weight starch to a classifier to concentrate the slurry by a factor of at least 5 and produce a concentrated slurry, wherein the classifier has at least one overflow exit and at least one underflow exit; drawing off the overflow and underflow from the classifier; feeding the concentrated slurry from the underflow exit of the classifier into a settling tank having at least one underflow exit and at least one overflow exit to produce an underflow layer of starch with a concentration of at least 40% starch proximate to the underflow exit and an aqueous overflow with a concentration of less than about 5% by weight starch proximate to the overflow exit; drawing off the overflow from the tank; and opening a orifice at the underflow exit of the tank to allow the distal most fraction of the underflow to exit the tank.

A constructed wetland system enhanced by immobilized laccase, it includes wetland plants, a matrix layer and a water distribution system, the wetland plants growing on the matrix layers, the matrix layer including a laccase catalyst and gravel, the laccase catalyst and gravel are distributed at intervals in a modular manner in a ratio of 1:5, the water distribution system is arranged on both sides of the matrix layer. The laccase catalyst is prepared by using a co-immobilization technology. The system improves the removal effect of hard-to-degrade organic matter in wastewater, and solves the problems of toxicity and stress of the hard-to-degrade organic matter existing in the prior art and the problems of matrix adsorption saturation.

The present invention relates to an anaerobic column reactor for biodegradation of wastes. Particularly the present invention relates to a process for conversion of biodegradable wastes to biogas and compost. More particularly, the present invention relates to an anaerobic reactor with unique arrangement of expanded and constricted portions alternatively placed vertically over each other which enhances the mixing pattern and thereby the mass transfer rates while controlling the biomass washout by regulating the upflow liquid velocity.

A single step pretreatment of wastewater or recreational water is provided comprising treatment with nanocomposites consisting of an anchoring particle such as a clay mineral and one or more polymers.

A nitrate-reducing electrode, and methods of making the nitrate-reducing electrode are disclosed. The nitrate reducing electrode includes catalyst particulates disposed on water permeable substrates with the use of electrodeposition, electroless deposition, electrospinning, or thermal treatment. The catalyst particles include metals and metal oxides. The water permeable substrates are preferably made of carbonaceous materials using electrospinning and thermal treatment.

Embodiments described herein are directed to methods and systems for treating wastewater or storm water using vermifiltration. The wastewater can come from various sources, such as agricultural sources, municipal and industrial sources, wineries, the dairy industry, and many others. The systems can include vermicomposting beds that are capable of removing high amounts of contaminants, pollutants, and/or toxic substances from wastewater. The wastewater may be applied to vermicomposting beds, for example, by an irrigation system. The irrigation system may provide, for example, improved bed coverage and more even saturation. The vermicomposting beds can remove various harmful substances from the wastewater, such as petroleum products; industrial chemicals; heavy metals (e.g., lead, mercury, cadmium, arsenic); pesticides (e.g., atrazine, chlorpyrifos); and organic compounds (e.g., phenols, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs)).
