A method for treating an aqueous fluid containing a biodegradable organic substance in an installation that includes an upflow bioreactor containing a sludge bed, wherein the sludge bed includes biomass, an external separator, and a conditioning tank. The method includes treating the fluid in the conditioning tank; feeding the treated fluid into a lower part of the bioreactor and forming biogas; withdrawing the fluid from an upper part of the bioreactor, which withdrawn fluid includes biomass; feeding the aqueous fluid withdrawn from the upper part of the bioreactor into the external separator, wherein the aqueous fluid that includes the biomass is separated into a liquid phase and a fluid phase enriched in biomass; returning the fluid phase enriched in biomass from the external separator to the bioreactor; and returning a part of the liquid phase to the conditioning tank.

The disclosure relates to a treatment method for sludge utilization in a sewage treatment plant, in particular to a method for reducing heavy metal content of sludge-based biocoke. The disclosure includes following steps (1) to (5): step (1): concentrating a residual sludge produced by a municipal sewage treatment plant to be with a moisture content of 95-98%; step (2): conditioning the concentrated sludge in a sludge bioleaching tank for 48 hours, with a pH value of the sludge being reduced to below 4.5; step (3): pumping the conditioned sludge into a high-pressure diaphragm plate and frame for a press filter dewatering to obtain a dewatered cake with a moisture content less than or equal to 50%; step (4): delivering the dewatered cake into a sludge dryer for crushing, heating and drying to obtain the dried sludge with a moisture content of 15-22%; and step (5): carbonizing the dried sludge into sludge-based biocoke at a high temperature in a pyrolytic carbonization device with a carbonization temperature of 500-650° C.

The invention provides methods and compositions for reducing the amount of water required in an industrial process, especially a bottling process such as beer or beverage manufacturing. The method comprising the steps of: collecting water used to rinse cleaned and/or dirty recycled bottles, spraying the collected water at a food contacting piece of equipment as part of a CIP rinse, and passing the CIP second rinse water into a cooling tower as make-up water. The method allows for the re-use of water already in the system but by being careful where each water stream goes the water does not accumulate contaminants that would damage the cooling tower or foul the bottled product or vessel that is cleaned by CIP method.

“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.

The invention relates to a continuous process for treating organic waste taking place in a plant, said process for treating organic waste comprising a process of anaerobic digestion of a first part of said waste, which takes place in at least one digestion chamber, and a process of aerobic composting of a second part of said waste, which takes place in at least one composting chamber, the process for treating organic waste comprising the steps of:—collecting digestate and biogas at the end of said anaerobic digestion process,—collecting compost and humic percolate at the end of said aerobic composting process,—feeding at least part of said digestate

A method for reducing beverage loss during loading of beverage into an ethanol concentration system having a set of reverse osmosis pressure vessels, each pressure vessel having a feed inlet, a retentate outlet, and a permeate outlet. The method includes feeding deaerated water into the feed inlet of a first pressure vessel, feeding the beverage into the feed inlet of the first pressure vessel, monitoring an alcohol percentage at the retentate outlet of a second pressure vessel, the second pressure vessel coupled directly or indirectly to the first pressure vessel, and coupling a retentate from the retentate outlet of the second pressure vessel to a feed tank coupled to the feed inlet of the first pressure vessel when the alcohol percentage is within a first target range of 0.5 to 18% alcohol-by-volume (ABV).
