Disclosed is a pore adjusting filtering apparatus including: a cylinder having a plurality of holes and in which a screw is rotatably installed; an endless track coupled to an outer peripheral surface of the cylinder by a cylinder, an endless track pin, and a support to be rotatable together with the cylinder; a fiber yarn bundle support rod inserted into the endless track to be connected to the endless track; a fiber yarn bundle, one end of which is fitted with and supported by the fiber yarn bundle support rod; a fiber yarn bundle support net for supporting the fiber yarn bundle while being attached to an outer peripheral surface of the fiber yarn bundle; a cleaning separator fixedly installed at an upper outer side of the cylinder; and an ejector installed on an upper outer side of the cylinder.

A filtrate collector element includes a hollow body forming a first opening portion, a second opening portion, and an intermediate portion. The intermediate portion forms a conduit between the first opening portion and the second opening portion. The collector element may be coupled with a pressure filter plate element. The outer dimension of the first opening portion is smaller than the inner dimension of the second opening portion, such that first opening portion of a preceding collector element can be at least partly nested in the second opening portion of a subsequent collector element. A pressure filter plate element, a horizontal pressure filter, a method for providing a continuous filtrate conduit and a method for operating a pressure filter are also concerned.

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.

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).

A device is for separating a medium comprising a mixture of a solid portion and a fluid portion. The device has a filter arrangement with a displaceable filter element having a plurality of openings that allow the fluid to be disposed through the openings while maintaining the solid portion on the filter element. The device further has an inlet for feeding the medium to the filter element and an outlet for discharging the solid portion from the filter element after that the fluid has been separated from the solid portion. The device further has an obstruction has an elastic element extending towards a surface of the filter element and adapted to contact the surface while allowing the medium to be displaced from the inlet to the outlet.

An oleophilic separation apparatus has a rotatable metal cage and at least one oleophilic sieve in frictional engagement with the rotatable metal cage. The oleophilic sieve is made of an oleophilic material such that a bitumen phase adheres to the oleophilic sieve upon contact. A plurality of apertures in the oleophilic sieve allows aqueous phase to escape from the rotatable metal cage. A hot zone is provided that has at least one rotation member and a source of heat. The oleophilic sieve is in frictional engagement with the at least one rotation member. The hot zone heats the bitumen phase adhered to the oleophilic sieve to allow for collection of the bitumen phase.

An apparatus includes a materials separator that includes a continuous filter belt disposed around a plurality of rollers. The apparatus also includes a pressure differential system operatively coupled to the separator and configured to adjust a pressure differential across the continuous filter belt. A vacuum is applied to the continuous filter belt and a fluid portion of the slurry on the continuous filter belt is drawn through the continuous filter belt. An apparatus includes a materials separator having a first deck with a first continuous filter belt and a second deck with a second continuous filter belt.
