Abstract: The present invention provides, in at least one embodiment, a system and method for producing cleaner water and air without using additional power. The system produces cleaner water by heating the sucked air, which improves the efficiency of the air stripping. The system produces cleaner air by fanning the contaminated air through a thermal oxidizer and/or a carbon filterator. The fanning is powered by a belt pulley powered by the gravitational force from the contaminated water.

Abstract: An assembly for removing grit particles from a fluid having a flow. The assembly includes a tank having walls for holding fluid for separation of grit particles from the fluid, a fluid inlet for flow of fluid into the tank, a fluid outlet for flow of fluid from the tank, an inlet diffusion baffle assembly including a baffle positioned to direct fluid flow toward the tank walls and a lower chamber of the tank, and an outlet baffle assembly including a baffle positioned in a rear of the tank at an upward slope from the center of the tank toward the fluid outlet configured to direct fluid flow toward the center of the tank.

Abstract: An assembly for removing grit from a fluid comprising a tank with a fluid inlet into the tank and a discharge from the tank. A flow directing assembly is positioned in the tank adjacent the fluid inlet and includes a substantially U-shaped surface opposite the fluid inlet such that fluid entering the tank through the inlet is caused to have a reversed flow in a direction more than 90 degrees from an inlet flow direction. At least one embodiment of the assembly further comprises a baffle positioned proximate the tank discharge to control flow adjacent the discharge. Yet a further embodiment of the assembly includes a screw conveyor positioned in a trough of the tank and a baffle is positioned proximate the trough to minimize fluid flow velocity adjacent to the screw conveyor.
