The invention relates to a transverse disc (60) of a centrifuge screw (30) for stabilising a screw hub structure. According to the invention, at least one opening (70) is formed at least in some sections on at least 75% of all the imaginary circle lines (71) of the transverse disc (60) between the centre point (M) and the transverse disc circumference (72).

A centrifuge system includes a centrifuge and a feed line fluidly connected to centrifuge with the centrifuge driven by a hydraulic system. The hydraulic system includes an electric motor driving a hydraulic pump connected to a fluid reservoir with the hydraulic pump providing hydraulic fluid to one or more hydraulic motors which in turn rotate the centrifuge. The system includes a pressure sensor for measuring fluid pressure and a speed sensor for measuring the rotational speed of the centrifuge. A controller can be in communication with the hydraulic system and the sensors and can receive measurements from the sensors and adjust the pressure of hydraulic fluid flowing to the one or more hydraulic motors to maintain a rotational speed of the centrifuge based on differing loads. The system can include one or more valves, controlled by the controller, which can also adjust the hydraulic pressure of the system.

The invention relates to: an inlet region (80) of a centrifuge screw (30), the centrifuge screw (30) having, at least in the inlet region (80), a screw hub (32) with an open wall structure, in particular with longitudinal bars (58); and an inlet tube opening (47) of an inlet tube (46), the inlet tube opening (47) opening into the inlet region (80). Opposite the inlet tube opening (47) there is an impact element (70), in particular an impact disc, having an acceleration element (75), the acceleration element (75) being designed such that a medium impinging on the acceleration element (75) can be accelerated in the direction of open spaces (85) of the open wall structure, said open spaces being in particular between the longitudinal bars (58).

A system for extracting nutrients from raw manure comprises: a manure pump for transferring manure from a reception pit to a rotary cutter configured to cut fibers of the raw manure to a desired length to generate a manure slurry. The manure slurry is transferred to a preprocessing tank having an agitator for agitating the manure slurry. An infeed pump transfers the manure slurry from the preprocessing tank to a decanter centrifuge, the centrifuge having at least one solid outlet and at least one liquid outlet. A control system controls a flow of the raw manure from the manure pump to the rotary cutter, and from the rotary cutter to the preprocessing tank, the infeed pump and the decanter centrifuge, and also controls each of these elements of the system. A nutrient content of the resulting liquid centrate is reduced by at least 50% as compared to the raw manure.

An entirely water-based, energy self-sufficient, integrated in-line waste management system is provided for comprehensive conversion of all organic fractions of municipal and wider community waste to fuels suitable for use in transportation, with all solid residues converted to high nutrition compost. The system is based on a combination of pre-treatment, involving alkaline hydrolysis and saponification; three-way separation of the pre-treated waste into different streams that are each directed to suitable further processing including fuel production; which includes biodiesel generation in a continuous-flow catalytic esterification unit, and anaerobic digestion to produce methane or other small molecule biofuel. Remaining solids are converted to compost in a quasi-continuous process.
