Abstract: A filter system configured to remove microfibers released from textiles being processed in a fluid. This fluid is sent into a filter housing containing a filter cartridge which in turn contains a movable inner filter. The movable inner filter is sufficiently flexible as to permit random movement in the fluid so that the inner filter rubs against the cartridge housing thereby removing particulate matter from the cartridge housing, thereby extending the useful life of the filter cartridge.

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.

Abstract: A waste filtration system is provided, suitable for separating waste content in a waste stream, for use in heat recovery, including a filter screen, auger and extractor pump. A novel filtering process includes steps of adjusting extraction rate of waste content by feedback measurement such that a target set-point is maintained. The feedback control is provided by either use of a variable speed motor detecting load change on the auger or sensors correlated to waste content, and displacement type extraction pump The waste filtration system can be used in a closed loop without leaks or open waste. The resulting filtered fluid is suitable for improving performance in heat exchange and recovery arrangements.
