  • Publication number: 20150101974
    Abstract: The invention relates to a filter for continuous filtration of a suspension under pressure, with a pressure vessel (1), rotating filter elements (2) disposed in the pressure vessel (1), where the filter element (2) passes through one filter cycle for each rotation, with filter zones in liquid and gaseous phase, also with filtrate channels (4?) that are connected between the filter elements (2) and separate filtrate outlets (14, 14?, 215) for each filter zone, as well as a device to control the individual filtrate zones by means of a control disc (44), where the control disc (44) has filtrate outlets (114, 115) for liquid and gaseous phase. It is primarily characterized in that a venting zone (46) is provided before the filtrate outlet of the liquid phase, viewed in the direction of the filter cycle. Thus, the compressed air in the filter elements (2) and filtrate channels (4?) can be carried off and pressure-relieved in a favorable manner.

  • Patent number: 8968572
    Abstract: In a device and a process for purifying water which is contaminated with sulphate ions and heavy metal ions, the water is collected in a water reservoir and a substance having basic activity in water is fed to the water reservoir in such a manner that a precipitant having heavy metal ions is precipitated from the water, wherein at least a subquantity of water is taken off from the water reservoir and is separated into pure water which is substantially freed from sulphate ions and heavy metal ions and dirty water which is enriched with sulphate ions and heavy metal ions. The dirty water is at least in part recirculated to the water reservoir, as a result of which a concentration of sulphate ions in the water reservoir is achieved such that a precipitant having sulphate ions is precipitated from the water.

  • Patent number: 8945377
    Abstract: An installation-free water purifying device comprises a raw/waste water common container and a filtering body. This raw/waste water common container is separated by a partition into an upper space and a lower space. The filtering body has a storing space, a purified water container, a filtering unit, and a flowing controller. Raw water is initially stored in the raw/waste water common container 10. Next, raw water in the upper space is pumped to the filtering unit for water filtering and then guided as purified water into the purified water container. Waste water generated from the filtering unit is guided into the vertical guiding portion so as to push the raw water in the lower space moving upward. In which, it does not require any complicated installing work. Waste water can be recycled. The user can start to use it quickly by an electric plug.

The treatment sections are distributed through the various housing portions in logical groups to perform various kinds of filtering. The housing portions are detachable and sealably stackable in multiple configurations, thus passing water through more or fewer treatment layers, depending on the quality of the incoming water.

    Abstract: A solvent filtration and recovery system for filtration and recovery of a solvent-based liquid used in dry cleaning includes filtration tank having filter chamber with motor-driven spin filters which are selectively operated. A valve and conduit arrangement allows the liquid from dry cleaning to enter the filter chamber for filtering and flows out as filtered liquid while the spin filters are not rotating. The arrangement allows initial at least partial draining of the solvent-based liquid in the filter chamber after such filtration procedure. A recovery tank is in communication with the filtration tank through a main drain. A motor drives the spin filters during a recovery procedure, in which centrifugal force caused by the rotating spin filters for a predetermined amount of time removes by-product from the spin filters, which is drained off from the filtration tank. A reservoir stores the solvent-based liquid and receives the liquid from both the recovery tank and the filtration tank.

  • Patent number: 7935251
    Abstract: A facility for treating solid and liquid waste includes a receiving station, a screening station, a preprocessing station, an alkali mixing station, a press station and a processing station. The screening station is connected to an inlet capable of receiving liquid and solid waste and includes a screen for capturing at least some of the solid waste. The preprocessing station is in fluid communication with the screening station, and includes a degrit chamber for settling out an additional amount of the solids. The alkali mixing station includes an alkali for mixing with the waste to stabilize the waste at a predetermined pH level. The press station receives the stabilized waste and includes a press for separating out an additional portion of the solids. The processing station includes at least one aerobic microorganism generating unit for converting nitrites into nitrogen gas and consuming carbon-based waste material.

  • Patent number: 7887872
    Abstract: Method and arrangement for separating impurities from the machine circulation of a processing agent of a processing station used in processing paper or board, in which method the processing agent is led from a reservoir (1) to the processing station (2), where it is spread on the surface of the web being processed, and the excess processing agent led to the processing station (2) agent is led back to the reservoir (1). The flow of processing agent coming from the processing station (2) is led to at least one pressure sieve (6), which is located below the level of the processing station (2), in such a way that the feed pressure of the processing agent is created on the basis of the difference in height between the station (2) and the pressure sieve (6).

  • Patent number: 7553416
    Abstract: New silica gel materials and novel methods of producing such are provided. The method itself entails a manner of mixing the reactants together in a one-pot process such that the time required for aging is reduced without compromising the ability to target pore size production. In such a way, the pH of the reaction drives pore size development, thereby permitting a more efficient process to be followed in terms of expensive drying/heating steps being reduced timewise, if not altogether. Furthermore, in one embodiment, the resultant gel materials exhibit a certain pore size minimum while simultaneously exhibiting a degree of softness heretofore unavailable. As such, not only is this novel method more efficient in silica gel manufacture, but the resultant materials are completely novel as well. The gel materials made therefrom may be utilized in a variety of different end uses, such as cooking oil filtration, soft skin cleansers, dental abrasives, and the like.
