摘要： A filter unit and a filter cage, the filter unit comprising a filter chamber and a filter cage. The filter chamber comprises opposing first and second end walls, a sidewall therebetween, and an opening in the second end wall. The filter cage is rotatable in the filter unit and comprises a sidewall comprising filter media and an opening at a first end for the filter cage. The filter cage is removable via the opening in the filter chamber. The filter chamber further comprises an inlet to pass feed liquid into the filter cage via the opening and an outlet for filtered liquid. The filter unit further comprises a drive shaft to rotate the filter cage. A connection member in the filter chamber forms a rotary seal and a detachable connection to the filter cage. This arrangement permits removal and emptying of the filter cage a single operation amongst other benefits. In alternative aspects a filter cage comprises a moveable member and a user operable portion for extraction of filtered microparticles through the opening.

摘要： A drilling mud remediation and drilling cutting treatment device and method. There are three main components: a vacuum liquid solid separator; a pelletizer; and an induction furnace. The liquid solid separator has a seamless filter belt configured to carry a mixture of liquids and solids over a vacuum. A slurry comprised of drilling mud and cuttings is deposited on the filter belt. An applicator ensures that the slurry is deposited evenly across the entire filter belt at a uniform thickness. The vacuum removes most of the liquids for further treatment and reuse. The solids are transferred to a pelletizer which compacts them into relatively uniform pellets while removing much residual liquid. The pelletized cuttings are then passed through an induction furnace, which removes any residual liquids, renderings the cuttings safe for disposal.

摘要： Ultrasound dehydration device applied to a filter made of ceramic, textile or any other material or porous structure, operated by vacuum or pressure means for the solid-liquid separation of solid particles in suspensions. The ultrasound device actuates on the slurry paste (cake) which forms at the surface of the filter as a result of the filtration cycle in the liquid medium. The device is comprised of one or a plurality of transducers (5) which irradiate by direct contact the cake (3) formed at the surface of the filter (1). The device operates during the cake dehydration phase, that is when the filter is outside the suspension. The invention discloses the ultrasound device and process which are applicable to a conventional filtering system activated by vacuum or pressure.

摘要： There is described a system and a process for optimizing and controlling upstream fluid treatment processes using information on fluid characteristics obtained from response variables of a separation device (such as the belt speed or water level of an RBF). This system and process allow for the upstream or downstream treatment processes to be adjusted and optimized against the instantaneous operating conditions of the separation device such that both the pre-treatment and post-treatment processes and the separation system always run at an optimal efficiency. Additionally, since the information obtained from the response variables of the separation device truly reflect the fluid characteristics at the point where the separation system is installed, the same can be used to control a downstream process (for example, the amount of oxygen required in the biological oxidation stage or the sludge retention time in an side stream sludge treatment process such as fermentation or anaerobic digestion).
摘要翻译：描述了使用关于分离装置的响应变量（诸如RBF的带速度或水位）获得的关于流体特性的信息优化和控制上游流体处理过程的系统和过程，。该系统和过程允许上游或下游处理过程相对于分离装置的瞬时操作条件进行调整和优化，使得预处理和后处理过程以及分离系统总是以最佳效率运行。此外，由于从分离装置的响应变量获得的信息真实地反映了分离系统安装点处的流体特性，因此可以使用该信息来控制下游过程（例如，生物氧化阶段或在侧流污泥处理过程如发酵或厌氧消化中的污泥停留时间）。

摘要： An assembly for separating solid phase material from a slurry that comprises a pressurized filtration unit including a vessel and filter media. A slurry (5) is fed to the filtration unit (10), where it is separated into a solid phase material and a liquid phase material. The filtration unit (10) has a solid outlet (12) for discharging the solid phase material to a material transport (15). The material transport (15) moves the solid phase material to a depressurizing chamber (20) that has a lower pressure than the filtration unit (10). As the solid phase material enters the depressurizing chamber (20), it is exposed to the lower pressure of that chamber. The material transport maintains (15) the pressure difference between the filtration unit (10) and the chamber (20). Subsequently, the depressurized solid phase material can be conveyed to other equipment for drying or other processing.
