“VINASSE TREATMENT PROCESS BY FLOTATION IN FLOW”, more precisely, it is a vinasse treatment process, by high performance flowing flotation system in industrial plants' facilities, resulting in obtaining concentrated vinasse sludge and treated vinasse, being said process comprised by vinasse treatment, which consists of treatment steps performed inside flotation tank, which comprises succession of coagulation systems and basins, flocculation, combined with aeration and oxygenation, in addition to a system of nano and micro bubbles in flotation basin, in which vinasse naturally flows into its storage tank, being said process results in formation of surface sludge and treated vinasse.

A method for treating wastewater and an activator for treating wastewater that maximizes the utilization of microorganisms such as Bacillus bacteria in an activated sludge treatment of wastewater while minimizing treatment cost. In the method for treating wastewater, wastewater including organic matter is introduced into a treatment tank and the wastewater is subjected to an activated sludge treatment by microorganisms in the treatment tank, wherein an activator containing a component for activating the microorganisms is added to the wastewater to be subjected to the activated sludge treatment in the treatment tank; and at least 50% (by quantity) of the entirety of the activator has a particle size of less than 10 pm. Also provided is an activator therefor. The microorganisms preferably include Bacillus bacteria.

According to one embodiment, a method for removing antimicrobial material from a composition includes providing a container that contains a plurality of carbon elements such as granules, rocks and sheets. The carbon elements are submerged with a liquid and a composition that includes an antimicrobial material is deposited in the container. The carbon elements are configured to remove the antimicrobial material from the composition. The level of the liquid in the container is monitored and controlled to maintain a submerged condition of the carbon elements.

The object is to provide an activated sludge treatment method whereby production of excess sludge is brought substantially to zero; and a method for upgrading existing waste water treatment equipment, employing this method. The method includes a step (1) in which sludge 1 produced in a bioreactor is supplied to a waste water aeration-conditioning tank for activated sludge treatment; a step (2) in which waste water into which the sludge 1 has been mixed is subjected to aeration-conditioning to bring the oxidation-reduction potential to a positive value, and the conditioning treated waste water 1 supplied to the bioreactor; a step (3) in which released water from the bioreactor is considered to release water.

A supercritical water oxidation (SCWO) system with a well-mixed SCWO reactor, a feedstock supplied to the well-mixed SCWO reactor by a feedstock supply line, a recirculation loop flow regulator in fluid communication with the well-mixed SCWO reactor; and a recirculation loop which includes the well-mixed SCWO reactor and the recirculation loop flow regulator, such that the recirculation loop flow regulator receives an oxidant from an oxidant supply line and a first portion of a reactor effluent from the well-mixed SCWO reactor and supplies the oxidant and the first portion of the reactor effluent to the well-mixed SCWO reactor. The SCWO system also includes a heat transfer unit operationally associated with the well-mixed SCWO reactor which performs at least one of: heating the well-mixed SCWO reactor and cooling the well-mixed SCWO reactor.

An automated food waste processing system including an enclosure secured to prevent unauthorized access to contents contained therein, the enclosure including a plurality of exterior walls and a food waste processing system housed within the enclosure. The food waste processing system including an imaging system configured to capture a plurality of images of the food waste and the non-biodegradable material received by the sorting receptacle, a processing system configured to process the plurality of images using a trained neural network to identify at least plastic waste and metal waste as the non-biodegradable material when included in the food waste input stream as received by the sorting receptacle, and a sorting system configured to, in response to instructions received from the processing system, automatically locate and remove the non-biodegradable material from the sorting receptacle to create a bio-degradable input stream to the anaerobic digester.

An apparatus for filtration has a feed of sludge, containing liquid, solids and gases fed into a tank, the tank containing at least one spinning separation filter comprising a filter cone set having a filter screen, and a barrier cone, arranged roughly in parallel, and defining a conical workspace between them, the conical workspace having a peripheral opening to the tank and a central opening communicating with the interiors of one or more hollow shafts supporting the barrier cone and the filter cone, the upper shaft supporting the barrier cone having an upper axial channel for the exit of gases, the lower shaft supporting the center of the filter cone having a lower axial channel for the exit of liquid or oil, motor means for producing rotation in said at least one spinning separation filter, and a filtrate liquid reservoir located underneath the filter cone for capturing the filtrate passing through the filter screen.

Disclosed herein are methods, systems, and devices for generating electricity from an effluent source. In the presence of electrogenic bacteria and substrate electrodes, an electroactive biofilm is produced which possesses bioconductive capacity for efficiently producing an electric current while treating an effluent source such as, e.g., wastewater. This disclosure relates generally to the production of electricity from a biological source. In particular, this disclosure relates to microbial fuel cells (MFCs) and other bioelectrochemical systems (BES) that exploit an exogenous fuel source.

A method and apparatus for collection and disposal or utilization as a carbon neutral fuel of fats, oil and grease that includes a first porous container, a second porous container, and a grease trap having an inlet and an outlet. The first porous container is positioned proximate the grease trap inlet and the second porous container is positioned proximate the grease trap outlet. The first and second porous containers are formed of a porous fabric and contain an absorbent, organic hydrocarbon material capable of absorbing a quantity of fats, oil and grease. The second porous container may be positioned on either side of the grease trap outlet (within the grease trap or intermediate the outlet and an exit pipe) and may be held in a stationary manner via a tether and/or a hinged door having a flange for capturing and holding the porous container in a stationary manner.
