Abstract: A normal flow filtration system having a housing with one or more filters contained within a bowl and attached to the outlet of the system. Liquid enters the bowl, contacts the surfaces of the one or more filters. Impurities are trapped in the filter and the filtered liquid flows through to the outlet. Parameter(s) such as flow rate, transmembrane pressure drop and/or time are measured and when met, filtration ceases. A backflushing occurs through the filter(s) so as to remove the impurities from the filter. This backwashed material is directed to an outlet of the bowl that is connected to a drain. Additionally a port formed in the side of the housing adjacent an outer surface of the filter(s) can be used to provide a lateral washing of the filter(s). The system is then recirculated in a downstream manner to reestablish equilibrium and filtration is then restarted.

Abstract: The present invention relates to a system and a process of running the system that allows for the long term filtration of product without loss of filtration capability due to clogging or fouling. The system is a normal flow filtration system having one or more filter cartridges attached to an outlet of a housing in the system. The filter cartridge(s) are contained within a bowl and depend preferably vertically from the outlet. Liquid enters the bowl of the housing and contacts the outer surfaces of the one or more cartridges. Impurities are trapped on or in the surface of the filter and the filtered liquid flows through the filter and through the outlet. One or more parameters such as flow rate, transmembrane pressure drop and/or time are measured and when the desired parameter(s) are met, the filtration ceases. A backflushing occurs back through the filter cartridges so as to remove the trapped impurities on or in the filter surface. This backwashed material is directed to an outlet of the bowl that is connected to a drain. Additionally a port formed in the side of the housing adjacent an outer surface of the cartridge(s) can be used to provide a lateral washing of the filter surfaces.

Abstract: Methods of operating candle filter systems for removing solids from MEG recovered from drilling fluids include passing an MEG rich stream to a candle filter system comprising a plurality of candle filter units in parallel, determining a concentration of TDS in the MEG rich stream, determining whether to operate the candle filter system in a low TDS mode or a high TDS mode based on the concentration of TDS the MEG rich stream, filtering the MEG rich stream in the plurality of candle filter units to produce a filtrate and a filter cake, determining to conduct a cleaning cycle of the candle filter units based on a pressure differential, and conducting a cleaning cycle to remove the filter cake from the outer surfaces of the filter candles. The cleaning cycle is modified to improve removal of solids from the filter candles of the candle filter units.

Abstract: A filter apparatus (10) has a plurality of filter elements (20) in a filter housing (12) having a filter inlet (50) for a fluid to be filtered and a filter outlet (52) for the filtered fluid. A pressure control device (42) has at least one control plate (58) located inside a connection chamber (14). The control plate laterally passes over individual upper element openings (54) of the filter element to be backwashed (20), in a predefinable sequence, covering the opening to an increasing degree and then exposing the opening again. A discharge opening (46) of the backwash device (44) is, at least in part, fluidically connected to a lower element opening (56) of the filter element (20) to be backwashed, as the pressure control device (42) moves towards the upper element opening (54).

Abstract: The invention relates to a device and a method for the purification of effluent. The device comprises a filter container (1A), containing a filter medium (2a, 2b), through which the contaminated effluent (3) is run in a direction (filtration direction), thus depositing dirt particles on the filter medium (2a, 2b). The risk of filter blocking is present in such filtration devices, especially at low filtration speeds. It is known that filter blockages can be avoided by the addition of flocculating agents or by increasing the filtration speed. The addition of flocculating agents makes the filter process more expensive and increasing the filtration speed reduces the quality of the filtrate. According to the invention, a high filtrate quality may be guaranteed without addition of flocculating agents with said device, whereby the cross-sectional area of the filter container (filtration area) running perpendicular to the filtration direction, expands in the filtering direction, whereupon the speed of the effluent being run through (filtration speed) continually reduces along the filtration direction.

Abstract: Equipment and procedure for the separation of solid particles and colloids suspended in liquid with automatic washing system of filtering meshes by means of high pressure water jets generated by a group of mobile spray nozzles, moved vertically by a hydraulic piston controlled by the same washing liquid pressure, operating when the filter is empty of liquid in filtration. The liquid jets are generated by a single nozzles or a group of nozzles, supplied with water through the shaft of the same piston. The nozzles are disposed in such a way to sprinkle the whole surface of the filtering mesh. Feeding the cylinder upper chamber with washing liquid with suitable pressure and flow determines the descending movement of the piston and with it of the nozzle or group of nozzles, mounted at the end of the piston shaft. The velocity of movement of the group of nozzles is regulated, creating in different ways, a resistance to the flow of liquid from the cylinder lower chamber. The upward motion of the plunger to its starting position is obtained by the injection of the liquid, which comes from a pneumatic device or from a dedicated circuit, in the cylinder lower chamber, with the consequent flow of liquid from the superior chamber through the nozzles.
