A separating system and method, of which the separating system includes a lower vessel including an inlet configured to receive a mixed fluid comprising a solid and a liquid. The lower vessel is configured to separate at least some of the solid from the liquid so as to produce a partially-separated fluid. The system also includes a first screen vessel configured to receive at least a portion of the partially-separated fluid, the first screen vessel including a first shell, and a first screen that is positioned within the first shell and at least partially removable therefrom, and a second screen vessel spatially oriented parallel to the first screen vessel and configured to receive at least a portion of the partially-separated fluid. The second screen vessel includes a second shell and a second screen that is positioned within the second shell and is at least partially removable therefrom.

A system which separates suspended substances from a liquid with a cyclone filter assembly that is rotationable symmetrically about a longitudinal axis. The invention is has a filter element with a filter wall configured as a single-layered perforated sheet with perforation holes having a hole diameter ranging from 5 .Math.m to 80 .Math.m inclusive at a radially outer filter wall surface with sensors for measuring a pressure difference between the filtrate chamber and a separation. A respective shut-off valve is located along first and second discharge lines, and a control actuates at least one of motor and at least one shut-off valve as a function of the pressure difference.

A method for automated cleaning of a filter basket in a bioreactor includes determining permeability of the filter basket. A control unit controls a suction unit for suctioning a residual liquid from the liquid tank, a liquid metering unit for dispensing a liquid having a predetermined liquid volume into the filter basket controls the suction unit to empty the liquid tank by suctioning a filtered liquid volume, measures the volume of the suctioned liquid volume, and sending a first measurement signal to the control unit. The control unit determines a permeability quotient from the volume of the extracted filtered liquid volume to the volume of the dispensed predetermined liquid volume and compares the permeability quotient with a permeability threshold. The control unit then controls a cleaning unit to perform a cleaning process of the filter basket if the permeability quotient is below the permeability threshold.

An automated computer-controlled sampling system and related methods for collecting, processing, and analyzing agricultural samples for various chemical properties such as plant available nutrients. The sampling system allows multiple samples to be processed and analyzed for different analytes or chemical properties in a simultaneous concurrent or semi-concurrent manner. Advantageously, the system can process soil samples in the “as collected” condition without drying or grinding. The system generally includes a sample preparation sub-system which receives soil samples collected by a probe collection sub-system and produces a slurry (i.e. mixture of soil, vegetation, and/or manure and water), and a chemical analysis sub-system which processes the prepared slurry samples for quantifying multiple analytes and/or chemical properties of the sample. The sample preparation and chemical analysis sub-systems can be used to analyze soil, vegetation, and/or manure samples. A soil collection system is disclosed which captures and directs samples to the sampling system for processing.

A pressure measuring device configured as a multi-function device operable as a differential pressure switch (DPS), a differential pressure transducer (DPT), a pressure switch (PS), a pressure transducer (PT) providing readings of high and low pressure zones, a data recording logger, and a backwashing controller. The pressure measuring device may use at least two piezoelectric sensors operable to measure pressure attributes. The associated electronic hardware, processing unit, cables and pressure tubing are retrofittable and packaged in a molded case, with no moving parts with the electronic hardware fully coated to make the device reliable and resistant to extreme environmental conditions. The device is configured for remote access, enabling remote device configuration, maintenance and servicing. The device is further operable to communicate with various external devices: a tablet, a smartphone and the like as a user interface and further provides wired interface with a programmable logic controller (PLC) via RS-485 interface.

A method to determine at least one filter operating parameter. At least one transponder arranged on or in a filter cartridge of the filter is contactlessly queried by a reading device. A transponder response is analyzed to evaluate the operating parameter. The transponder is subject to influences acting on the filter cartridge. As a result of the influences that the transponder is sensitive to, or sensitivity on transparency or damping properties of a transmission path of electronic signals between the transponder and the reading device, a transponder response behavior is changed to a degree detectable by the reading device or a downstream analysis unit which enables a statement to be made about the operating parameter. A device for determining at least one operating parameter of a filter or a filter cartridge arranged on or in the filter, and a filter cartridge are both provided.
