A liquid filtration system comprising a filtration tank with: a separating roof on which are mounted groups of hoses fixed to respective support plates; a fluid distributor plate comprising a central portion without perforations, and a peripheral portion with a plurality of perforations, said distributor plate being located between the hoses and a lower inlet duct for the water to be filtered comprising an upper opening for supplying liquid to the holes near the central portion of the distributor plate and a lower opening for supplying liquid to the holes of the peripheral portion which are furthest from the central portion. The filter comprises a filter material, an outlet duct for the filtered water at the upper area of the tank, a regeneration circuit of the filter medium; a filter self-cleaning circuit and a control panel.

A milking device for milking a dairy animal is provided with milking mechanism, a control system, a milk pipeline for transporting the milk from the milking mechanism to a milk tank, a milk filter and a cleaning device. The cleaning device includes at least one cleaning fluid holder, a heating device for heating cleaning fluid in the cleaning fluid holder, an additive storage holder for additive, an additive adding device for controlled addition of the additive to cleaning fluid, and a valve system for regulating flows of cleaning fluid and additive through the milking device. The cleaning device is configured for carrying out a cleaning cycle of the milking device with a prerinse with cold or tepid water, a hot rinse with heated water and an acidic or basic additive, a postrinse, and at least between the hot rinse and the postrinse, a counterflow cleaning step by passing cleaning fluid in counterflow through the milk filter. Thus, a milking device is provided that can be cleaned automatically as a whole including the milk filter. In particular, because the counterflow cleansing takes place after the hot rinse step, there is better removal of dirt and milk residues that are softened thereby, in particular from the milk filter.

A nutrient concentration and water recovery system includes a first suspended solids settling tank configured to receive a flow stream that includes a waste stream with a sludge stream. A first centrifugal pump is coupled to the first suspended solids settling tank. The first centrifugal pump having corrosion resistant wetted parts and variable speed drives to transfer or pressurize process flow streams. A first level transmitter coupled to the first centrifugal pump that provides output signals in response to a level of a process material within the first suspended solids settling tank. The first level transmitter is mounted in the first suspended solids settling tank. A first flow transmitter coupled to the first level transmitter is configured to measure a specific volume of material transferred out of the first suspended solids settling tank. A first pump is coupled to the first flow meter and configured to transfer a flush water that includes suspended solids and inorganics. A vibrating screen is coupled to the first pump. A process tank is coupled to the submersible pump. A sedimentation removal system and a removal device coupled to the sedimentation removal system are provided and configured to remove inorganizes out of a suspension.

A water filtration system and water filtration system head provide interchangeable water inlet and outlet ports, so that a direction of a flow of water through the water filtration system can be reversed by configuring a valve provided in the water filtration system head that attaches to a cartridge housing containing a water filter cartridge. The head has a first fluid channel communicating with a fluid volume between the cartridge housing and the outer surface of a water filter cartridge, a second fluid channel in communication with an inside of the cartridge, and a multi-position valve that either conducts inlet water from a first port to the first fluid channel and conducts outlet water from the second fluid channel to the second port, or conducts inlet water from the second port to the first fluid channel and conducts outlet water from the second fluid channel to the first port.

Filter device (1) for filtering extruded polymers comprising a containment body (2) defining at least one cavity (3), an inlet opening (4) in fluid communication with the cavity (3) via a respective inlet conduit (5), and an outlet opening (6) in fluid communication with the cavity (3) via a respective outlet conduit (7), and a support body (8) slidably inserted in the cavity (3) and interposed between the respective inlet conduit (5) and the respective outlet conduit (7) and having a seat (9) for housing a filter assembly (10) consisting of two perforated disks (11) and a filter screen located between the two perforated disks (11). The seat (9) has an inlet section (13a) having dimensions equal to an outlet mouth (5a) of the inlet conduit (5), and an outlet section (12a) with dimensions that are larger than the dimensions of the inlet section (13a) and equal to a maximum extension of an inlet mouth (7a) of the outlet conduit (7). The support body (8) is slidably movable in the cavity (3) along a main direction of movement (L) so as to produce different partialisations of the perforated disk (11) associated with the outlet section (12a) of the seat (9).

A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.
