A ballast water treatment system includes an ultraviolet irradiation device which irradiates ballast water flowing through a treatment line (a pipe) with ultraviolet rays, and a control unit. The ultraviolet irradiation device includes a light source which emits ultraviolet rays, and an illuminance sensor sensing an illuminance of ultraviolet rays received by the ballast water. The control unit controls the ultraviolet irradiation device to maintain at a prescribed dose a dose calculated using an illuminance sensed by the illuminance sensor and a flow rate of ballast water which flows through the ultraviolet irradiation device. When the sensed dose cannot be maintained at the prescribed dose by controlling the ultraviolet irradiation device, the control unit reduces a treatment flow rate of the ballast water which flows through the treatment line.

A device for continuously filtering material mixtures, particularly for separating contaminants out of plastic melts, includes a filter (3), which is rotatably arranged in a filter chamber (2) of a housing (1), at least one wiper (17) for lifting off contaminants retained by the filter (3), and a discharge device (18) for removing the contaminants lifted off the filter (2) by the wiper (17) from the housing (1). The discharge device (18) includes a discharge shaft (19), which is rotatably arranged at the housing (1) and which has at least one continuous opening (20) having at least one piston (22) which is movably guided therein.

Processes and systems for recovering products from a corn fermentation mash. In one example, a process for recovering products from a corn fermentation mash can include separating ethanol from a fermentation mash to produce a whole stillage. The fermentation mash can be derived from a ground corn product milled from a plurality of corn pieces. The plurality of corn pieces can include whole corn kernels, fragmented corn kernels, size-reduced corn kernels, milled corn kernels, or a mixture thereof. Greater than 25 wt % of the ground corn product can have a particle size of greater than 105 μm and greater than 80 wt % of the ground corn product can have a particle size of 425 μm or less, as measured according to AOAC 965.22-1966. The process can also include separating the whole stillage to produce a fiber rich portion and a filtrate.

The invention relates to a rotary pressure filter module (100) which comprises a rotary pressure filter (200) having a plurality of supply lines (302, 318, 330) for supplying a suspension, washing medium, drying medium, and optionally other operating media to be filtered and having a plurality of discharge lines (314, 326, 348) for discharging mother filtrate, washing filtrate, and filter cakes, different sensor devices (306/308/310, 322/324, 334/336, 316, 328, 349) being assigned to the supply lines and the discharge lines, and adjusting devices also being assigned to the supply lines, the rotary pressure filter module (100) additionally comprising a control device (400) which is connected to the sensor devices and the adjusting devices. According to the invention, the decentralised control device (400) assigned to the rotary pressure filter (200) is arranged on the rotary pressure filter (200) or in its immediate vicinity and has a signal input via which it can be brought into data exchange connection with a central control device, which does not belong to the rotary pressure filter module (100), of a higher-level production system.

The present disclosure relates to a bottle treatment machine including a pump/nozzle protector in the form of a screen. The screen includes an at least partially perforated surface and the screen is provided for passing a liquid of the bottle treatment machine therethrough. The bottle treatment machine further includes at least one scraper which rests at least partially on the at least partially perforated surface of the screen.
