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. Preferably, the particulate filter and the acid-neutralizing filter are positioned within a housing. A conduit having a pressure reduction section is arranged to create a pressure differential across the acid-neutralizing filter such that a portion of the fluid to be filtered by the filter apparatus passes through the acid-neutralizing filter.

Abstract: A dewatering system for separating a stream of liquid from the items traveling therein. The dewatering system includes a primary grid which catches the stream of liquid from a flume or other device. The liquid stream, but not the solid items, passes through the primary grid and is caught by a baffle which smoothly redirects the liquid. The baffle is arranged with respect to the primary grid so that the surface of the stream flow through the grid is substantially tangential to a leading portion of the baffle.

Abstract: The present invention provides a filter apparatus for use in removing impurities contained in a fluid that includes a housing, a full flow filter contained in the housing, the housing and the full flow filter arranged such that the entirety of the fluid to be filtered by the filter apparatus passes through the full flow filter, a bypass filter, and a conduit which contains a pressure reduction section. The full flow filter, bypass filter, and conduit positioned within the housing such that the bypass filter is positioned downstream of the full flow filter and the pressure reduction section is arranged to create a pressure differential across the bypass filter such that a predetermined portion of the fluid to be filtered by the filter apparatus passes through the bypass filter. The invention further provides a method of removing impurities contained in a fluid by filtration by introducing a fluid to a filtering apparatus including a full flow filter and a bypass filter; filtering 100% of the fluid with the full flow filter; creating a pressure differential across the bypass filter whereby a predetermined portion of the fluid filtered by the full flow filter is drawn through the bypass filter, thereby filtering the predetermined portion of the fluid a second time.

Abstract: An air bubble purging system for filters include a venturi valve in the drain line of the filter. The venturi valve is connected to a high pressure source line so that when a high rate of flow is produced in the high pressure source line, a venturi effect is created in the venturi valve to open the venturi valve and produce a vacuum in the drain line so that air bubbles are attracted into the drain line and purged.

Abstract: A cleanable backflushable re-usable dual full-flow and bypass filter includes a full-flow filter element providing filtered primary flow therethrough, a bypass filter element providing filtered secondary flow therethrough, a bypass tube conducting flow therethrough from said bypass filter element to said full-flow filter element, a venturi creating a low pressure zone aiding secondary flow through the bypass tube to assist in pulling the secondary flow through the more restrictive bypass filter element, wherein fluid, whether main fluid flow in the filtering direction or backflushing cleansing fluid flow in the opposite direction, flowing from the bypass tube changes direction at the venturi. During a backflushing cleaning cycle, a backflush deflector at the outlet end of the bypass tube in the venturi creates the directional change by changing axial flow of cleansing fluid through the bypass tube to radial flow at the outlet end of the bypass tube in the venturi and prevents straight-through rectilinear flow of cleansing fluid from the bypass tube to the filter outlet. Jets are provided, jumping the cleansing fluid across a radial gap between the bypass tube and the venturi throat to a region outside of the venturi and within the hollow interior of the full-flow filter element, to disperse and backflush the full-flow filter element.

Abstract: An adjustable continuous filtration system for cooking fats and cooling oils. Using a variable orifice restriction such as a valve, the amount of cooking fat or cooking oil recycled to a filter is controlled in accordance with the results of testing the discharged cooking fat or cooking oil for quality control, by changing the size of the orifice. If the discharged fat or oil not within industry standards, the proportion being recycled is increased. If the fat or oil tests appreciably above industry standards, the proportion recycled to the filter is decreased.
