Abstract: The present invention provides a filter apparatus for use in removing impurities and acids contained in a fluid that includes a particulate filter and an acid-neutralizing filter. The particulate filter and the acid-neutralizing filter may be positioned within separate housings or they may be positioned within a common housing. The acid-neutralizing filter contains an acid-neutralizing compound such as crushed limestone, calcium carbonate or magnesium carbonate.

Abstract: A method of coacting a fluid with a media, such as granular particles. The media is moved to an upper portion in an upright media container, and held there during a treatment cycle in which the fluid is coacted with the media. When the media requires regeneration, the media is allowed to fall to a lower portion of the media container where a regeneration fluid is passed through the media.

Abstract: A pipe line strainer has a strainer body having an inner body wall surface and defining a flow passageway, and further defining a strainer inlet in communication with the flow passageway and a strainer outlet spaced from the strainer inlet along the flow passageway in a direction for fluid flow, and a strainer basket disposed within the flow passageway between the strainer inlet and the strainer outlet. The strainer basket has a strainer basket wall defining a plurality of through apertures of predetermined cross dimension for flow of fluid from the strainer inlet toward the strainer outlet, the strainer basket wall dividing the flow passageway into a first region of flow upstream of the strainer basket wall and a second region of flow downstream of the strainer basket wall. At least one of the first region of flow and the second region of flow has an unequal distribution of flow due to change in incremental flow cross sectional area in the direction for fluid flow, with the larger cross-sectional area coinciding with an area of higher flow.

Abstract: A filter element constructed of stainless steel. The element includes a pair of filter media concentrically disposed to receive parallel flow of the filtrant. The element is adapted for disassembly to remove the filter media. The various component parts of the filter element may thereafter be easily cleaned and the filter media replaced. The filter media after being removed may also be cleaned and reused if desired. The component parts include appropriate guard assemblies to protect the filter media during handling and use.
