A brine injection machine for injecting brine to meat pieces is provided. The machine comprises an auxiliary frame (10) configured to carry a pre-filtering unit (6), and a pre-filtered brine tank (7), the auxiliary frame being detachable with regard to the main frame (1). At least one level sensors (32) is configured for detecting an amount of pre-filtered brine in the pre-filtered brine tank (7), and an electronic control device is configured for controlling the brine injection operation as a function of the amount of pre-filtered brine in the pre-filtered brine tank (7) that can be recycled, as detected by the at least one level sensor (32) at the end of a brine injection cycle. It is also disclosed a method for operating a brine injection machine according to the invention.

The present invention relates to a filter panel which is intended to be mounted in a drum filter, the filter panel comprising a peripheral frame to which a filter cloth is fixed, the frame being formed by two longitudinal members which are connected at each end by an end cross-member, characterized in that the filter panel comprises a lattice (R1) of crosspieces which connect the inner edges of the frame to one another, the lattice (R1) of crosspieces forming at least a first closed pattern (54) in the centre of the frame and comprising at least four diagonals which are inclined with respect to the longitudinal members and which extend from the first closed pattern to an inner edge of the frame.

The present invention relates to comminutors for breaking down waste and, more particularly, comminutors having a screen that rotates for directing large waste particles into a cutting assembly. In addition to a rotating screen, a second, stationary screen is provided that has horizontal ribs adapted to cooperate with interleaved ribs on the rotating screen so as create a composite fine screen at an inlet end of the comminutor, while creating a coarse screen at the outlet end of the comminutor.

A centrifugal solids-liquid separator system has a drum that spins about a rotational axis with a helical channel for moving solid particles up into a blower channel and out a blower outlet, wherein the drum is moved with a variable speed to cause the solid particles to move up the helical channel. The helical channel is configured along an inside wall of the drum and the solid particles from a slurry move up along the helical channel to a top flange and over this top flange into the blower channel. The blower then forces the solid particles out of the system. The liquid of the slurry flows from a receiving base configured at the base of the helical channel or drum, out of a liquid outlet to exit the system for collection or disposal. A motor spins the drum and may power the blower to operate the system.

Rotary drum filtering machine and method for filtration of harvested algae. A filtering drum, axially rotatable horizontally, includes a filtration basket with thermally coupled mesh netting for retaining algae and passing through liquid when filtering drum is rotated. Feeding liquid containing algae is fed into filtering drum via inlet pipe. Filtered algae retained on internal surface of filtration basket is scraped and collected, and removed through outlet pipe. Filtration basket is axially embedded and releasably secured to a support frame. Mesh netting is thermally pressed into filtration basket such that filtration basket polymer material penetrates through mesh netting apertures, and polymeric rod thermally pressed onto mesh netting fuses to filtration basket polymer material with mesh netting contained therebetween. Mesh netting includes wired mesh with wire diameter less than 1,000 pm and micron sized apertures having aperture diameter of 1 pm-500 pm to enable filtration of micron sized algae.

A conveyor-belt filtering device includes an endless filtering belt, which has at least one filtering element, a frame, a lower deflection apparatus and at least one upper deflection apparatus. The endless filtering belt has at least one collecting element, which is adapted for collecting foreign solids, in particular sand, stones, pebbles or the like, which are present in the liquid, in particular in an area of the lower deflection apparatus.

A filtering device and a washing machine. The filtering device includes: a filtering cavity, which has a water inlet, a filtered water outlet and a sewage outlet for discharging filtered impurities. A filtering mechanism is inside the filtering cavity, to filter the water entering the filtering cavity. A blocking mechanism separates the inside of the filtering cavity into a first space and a second space. The water inlet is communicated to the first space, and the filtered water outlet is connected to the first space. The cleaning particles are in the first space in the filtering cavity. The cleaning particles can prevent the deposition of filtered impurities during the filtration process and avoid clogging of the filtering device. The blocking mechanism can prevent the cleaning particles from entering the second space, and from flowing out with the water flow from the filtered water outlet or the sewage outlet.

A rotary disc filter designed to remove suspended solids from wastewater is provided with a high pressure media cleaning system. The high pressure media cleaning system comprises a sectioned manifold that extends along the side of an array of disc-shaped filter units. The sectioned manifold includes a plurality of hydraulic sections with each hydraulic section isolated from the other hydraulic section or sections. Communicatively connected to each hydraulic section is a plurality of spray bars that include nozzles. The spray bars communicatively connected to a particular hydraulic section is designated to clean only a section of the filter units at any one time. Pressurized water is supplied to one hydraulic section at a time. The pressurized water enters the hydraulic section and from the hydraulic section flows through the respective spray bars communicatively connected thereto and out the nozzles of the spray bars and in the process cleans filter media that form a part of the filter unit of a particular filter unit section.
