Methane is generated from animal waste by anaerobic digestion using bacteria. A screen separator removes suspended solids greater in size than a predetermined size ranging from about 50? to about 150?. An electrocoagulation unit electrochemically hydrolyses the waste, causing particles to settle out. A dissolved carbon air flotation has a CO.sub.2 bubbler for separating large particles from small particles by flotation. An anaerobic digester produces biogas. The digester has a biocurtain for growing the bacteria and a heat exchanger for heating the bacteria. The biocurtain surface is convoluted to retain the bacteria. A membrane module removes CO.sub.2. A knock out pot for removes droplets of water. A scrubber removes water vapor, particulates, and contaminant gas. A compressor boosts pressure. A gas chromatograph monitors the biogas composition. A flare skid lowers excess pressure for safety. Biogas is injected into a local pipeline system. A process control is used for controlling the anaerobic waste digestion system.

At least one aspect of the technology provides a self-contained processing facility configured to convert organic, high water-content waste, such as fecal sludge and garbage, into electricity while also generating and collecting potable water.

A multi-stage cavitation subassembly is described. The multi-stage cavitation subassembly includes: (i) a first cavitation-inducing feature for cavitating a fluid; (ii) a second cavitation-inducing feature that is located downstream from the first cavitation-inducing feature and is designed to cavitate the fluid after the fluid has undergone cavitation in the first cavitation-inducing feature; and (iii) a velocity-imparting component that, in a state of motion and when in contact with the fluid, imparts the fluid with sufficient velocity after the fluid has undergone cavitation in the first cavitation-inducing feature so that the fluid traverses from the first cavitation-inducing feature to the second cavitation-inducing feature.

A method of continuous hydrothermal carbonization of sludge containing organic matter involves a step of hydrothermal reaction carried out in a reactor, and at least one cooling step in which the sludge having undergone the hydrothermal reaction step is cooled. The hydrothermal reaction step includes: a step of injection of sludge in which the sludge is injected into the reactor by a first inlet; a step of injection of steam in which steam is injected into the reactor by a second inlet, the second inlet being distinct from the first inlet; a step of circulation, in which a mixture consisting of the sludge and the steam injected into the reactor is placed in circulation within the reactor; a step of continuous extraction of at least a portion of the mixture contained in the reactor by a sludge outlet. Also disclosed is a device for carrying out such a method.

A method and apparatus for organic waste treatment are disclosed. The method comprises the steps of adding a sorbent to a waste product to form a fluid matrix which may then be subjected to a compressive force to dewater the matrix. Thermal desorption and pasteurisation of the matrix may then be carried out. The sorbent added is draff, which may be obtained as a by-product from various industries, including the distillation of spirits. The apparatus comprises generally a dewatering compressor, but may also include a thermal desorption unit, which may thermally dewater the matrix and pasteurise it.
