The invention relates to a method and a device for improving the biodegradability of an organic sludge. It comprises at least two treatment cycles each of a total duration of between around 8 s and around 20 s and each comprising a first step of producing a first hydrolysed sludge emulsion in a first, reduced zone, by injecting a gas into said reduced zone. a second step of abruptly expanding the emulsion in a second zone—the expansion zone—and a third step of recovering the emulsion via a third, restriction zone.

The present invention relates to a multistage separation reaction tank for treating sewage sludge by forming a collection layer, a diffusion layer, a primary buffer layer, a secondary buffer layer, and an inorganic precipitate layer when treating an organic material by adding a liquid solvent having a specific gravity less than water to the sewage sludge. In addition, the present invention relates to a method for treating sewage sludge by using an alkane-based solvent, wherein the method significantly lowers the water content of the sewage sludge by using an alkane-based solvent which is in a liquid state and non-polar at atmospheric pressure and room temperature.

A settling basin of a wastewater treatment system includes a collector chain including chain links having a plurality of side bars, stepped connecting pins configured to join the plurality of side bars and including a first end including a head portion having a cross-sectional area larger than portions of the plurality of side bars through which the stepped connecting pin extends, end caps configured to receive second ends of the stepped connecting pins, and apertures defined in the end caps and second ends of the stepped connecting pins configured to receive a retaining element that holds the end caps in position on the second ends of the stepped connecting pins.

A gel emulsification system and method for converting fats, oils, and grease (FOG) into a solid acceptable for landfill disposal. The method may include mixing FOG with a detergent and water to form an emulsion, adding viscosifier and a cross-linking agent to the emulsion, and mixing the emulsion and the viscosifier and cross-linking agent to form a gel. The system may include a container adapted to hold solids and liquids without leaking, a powdered detergent in the container to mix with water and a FOG to form an emulsion, and a powdered viscosifier and powdered cross-linking agent in the container adapted to thicken and cross-link the emulsion to form a gel. The gel formed passes a paint filter test (SW-846 Test Method 9095B).

A dual-airflow cyclone flash drying device includes a feeding device, a fluidizing cyclone generator and a drying cylinder. The fluidizing cyclone generator is connected with the drying cylinder through a central connecting pipe. The tail end of the feeding device is provided with a porous plate doser that is connected with the central connecting pipe. The fluidizing cyclone generator adopts lateral air supply, air forms a cyclone along the circular outer wall to enter the central connecting pipe. A drying cyclone generator is arranged at the lower portion of the drying cylinder. The drying cyclone generator adopts lateral air supply, and after forming a cyclone, air spirally rises to make contact with fluidized granular sludge to evaporate sludge moisture into water vapor. A particle size selector is arranged at the upper portion of the drying cylinder, and an outlet flue is arranged above the particle size selector.

“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 of treatment of aqueous liquid contaminated by pollutants, includes (i) mixing the contaminated aqueous liquid with a mineral binder in order to produce an homogeneous slurry, (ii) depositing the slurry, (iii) letting the slurry set and harden, wherein the mineral binder includes Portland cement, and wherein the contaminated aqueous liquid includes organic pollutants.

A composition for solid pellets and a process for removing water from particulate material slurries produced by horizontal drilling, vertical drilling and dredging of bodies of water are disclosed. The composition comprises a precipitating agent, a purification agent and, optionally, a binding agent. The process comprises the steps of 1) water removal accomplished by diffusing a chemical reagent into the particulate material source stream that results in separating out a clean water fraction and 2) reacting the sludge with a demulsifier and a superabsorbent polymer that locks onto the water in the remaining slurry thus turning the slurry into a solid crust. The crust is ground into a particulate form and disposed in a landfill. The combined effect of the treatments is the thickening of the particulate material slurry from about 10% solids to about 25% solids. The removed water may be used for further drilling and drinking.

A device for sludge treatment comprises a supporting frame of an external casing defining a treatment chamber provided with one inlet opening of the sludge to be treated; one discharge opening of the treated sludge; at least one auger element housed within the treatment chamber, and adapted to move the sludge to be treated along a direction of advancement; and filtration means located internally to the treatment chamber and surrounding the auger element; at least one anodic element associated with the auger element, and application means for applying a potential difference between the anodic element and the filtration means, generating an electric field adapted to interact with the sludge to be treated to produce an electro-osmotic process.

The present disclosure relates to a sludge collector including: a plurality of flights collecting sludge in a settling basin; a chain connected to the plurality of flights to move the flights; and an attachment-integrated roller unit detachably coupled to an attachment connected to the flights, and preventing the flights from being reversed when the flights are operated.
