    Abstract: Disclosed herein are decanting backwash receiver assemblies, and related methods of fabrication and use. The present disclosure provides improved decanting backwash receiver assemblies for decanting of input feeds, and improved systems/methods for utilizing and fabricating the decanting backwash receiver assemblies. The present disclosure provides decanting backwash receiver assemblies utilizing porous media insert members and/or porous media surfaces for the decanting of input feeds. Exemplary decanting backwash receiver assemblies are configured and dimensioned to receive a filter backwash surge flow of slurry (e.g., solids and liquid mixture), and provide for settling of the solids from flow 11, and provide for decanting of a liquid layer above the settled solids, and optionally provide for de wetting the settled solids, and provide for discharge of the settled solids (e.g., liquid wetted) from the bottom of the assemblies.

    Abstract: Disclosed herein is an apparatus for filtering sewage and wastewater. The filtering apparatus has a vertical structure including a filtering belt comprising a filter bag or a filter mesh that can filter out fine impurities. For this, the filtering apparatus includes a drive motor that receives power to drive the apparatus, an upper drive drum that is operated by the drive motor, a lower rotating drum that is interlocked with the upper drive drum, and a filtering belt that is wound and rotated around the upper drive drum and the lower rotating drum. The filtering apparatus cannot only filter out fine impurities less than from 0.1 mm to 0.2 mm but also separate earth and sand, unlike conventional filtering apparatuses that cannot conduct them. Furthermore, because the filtering apparatus can be placed upright or inclined at a predetermined angle, it can be used in a water inlet passage that is 4 m to 5 m underground, and impurities filtered out from water can be transferred to a height higher than 10 m above ground.

    Abstract translation: 本文公开了一种用于过滤污水和废水的设备。 过滤装置具有垂直结构，其包括过滤带，该过滤带包括可以过滤出杂质的过滤袋或过滤网。 为此，过滤装置包括：驱动马达，其接收驱动装置的动力;由驱动马达操作的上驱动滚筒;与上驱动滚筒互锁的下旋转滚筒;以及卷绕过滤带 并围绕上驱动滚筒和下旋转滚筒旋转。 过滤装置不仅可以滤除小于0.1mm至0.2mm的细杂质，而且可以与不能进行它们的常规过滤装置不同，也可以分离土沙。 此外，由于过滤装置可以以预定角度直立或倾斜放置，所以可以在地下4m至5m的进水通道中使用，并且可以将从水中滤出的杂质转移到高于10的高度 m以上。

    Abstract: Process of fine filtering an alkaline metal cleaner containing emulsified soluble oil in which the requisite amount of aminopolyacetic acid or ammonium or alkali metal salt thereof is added to the cleaner periodically to maintain unchelated hardness in the range of zero to about 400 p.p.m. hardness expressed as CaCO3, and up to 2 percent by weight of free polyacetic acid or ammonium or alkali metal salt thereof, and the cleaner is filtered through a medium capable of removing solids larger than about 0.1 to 10 microns major dimension.

    Abstract: A filter device provides designs that permit variable levels of solid particle removal. The filter device retains the particles in the filter medium when removed, thus avoiding the re-entry of the particles when the power system has cooled down which occurs in conventional filters currently in use. The filter device incorporates elements made from stainless steel for (a) durability and high mechanical strength to endure high continuous flow pressures; (b) ductility so as to be pleated and shaped into a cylinder; (c) corrosion and high temperature resistance; (d) particulate removal in the range of 4-20 microns depending on the desired performance characteristics; (e) high percentage of contaminant removal; and (f) recyclability and reusability.

    Abstract: A filtration system for a fuel system for a marine vessel engine. The system comprising: an inlet for fluid connection to a settling tank; an outlet for fluid connection to a service tank; and an arrangement of plural primary filtration devices The arrangement is fluidly connected between the inlet and outlet so that fuel flowing from the settling tank via the inlet to the service tank via the outlet passes through at least one of the primary filtration devices. The system is configured so that each respective primary filtration device operates, independently of each other primary filtration device in: a first mode, in which the fuel flows in a first direction through a filter of the respective primary filtration device to remove contaminants from the fuel, or a second mode, in which a fluid flows through the filter in a second direction, opposite the first direction, to dislodge the contaminants.
