A tamper-proof fluid sediment trap including a central body portion having a central longitudinal axis, an outlet leg portion, a drip leg portion, and a supply leg portion. The outlet leg portion extends upward from the central body portion parallel to the central longitudinal axis and is configured to operably couple to an appliance. The drip leg portion extends downward from the central body portion and defines a shape being resistant to threading or tapping of an outer surface or an inner surface of the drip leg portion. The supply leg portion is configured to couple to a fluid supply line, extends radially outward from the central body portion, between the outlet leg portion and the drip leg portion, and has a central longitudinal axis extending perpendicular to the central longitudinal axis of the central body portion. The portions of the tamper-proof fluid sediment trap are monolithically formed.

An apparatus and methods for the separation of macroscopic solid body particles (SBPs) from a fluid stream contained in a conduit, such as a hose or pipe. The method involves utilizing a particle separator having a fluid inlet port connected to a fluid inlet conduit and a fluid outlet port connected to a fluid outlet conduit to change the direction (and optionally the velocity) of the fluid stream within a lumen of an enclosed vessel component of the particle separator sufficiently to permit SBPs to fall by gravity (and/or to descend due to inertia) into a removable receptacle within a bottom portion of the vessel component while directing the flow of cleansed fluid to the fluid outlet port of the particle separator.

A separator vessel has inlet, fluid outlet, and sand outlet ports. Each of the fluid and sand outlet ports are spaced below the inlet port. The separator has an enclosure between the inlet and fluid outlet ports. The enclosure redirects the fluid stream and defines an inner cavity above a lower edge of the enclosure, the lower edge defining a liquid flow area. The separator has one or more vanes extending along an outer surface of the enclosure which redirect the fluid stream along a curved flow path as the fluid stream flows toward the lower edge, and a plurality of apertures adjacent to the vanes, the apertures permitting fluid flow into the inner cavity of the enclosure. The fluid outlet port is disposed within the inner cavity above the lower edge of the enclosure and below one or more apertures.

A side-flushing mechanical filter system includes a spring positioned within a pipe and a plurality of plates attached to the spring, each plate defining at least one hole, and a rod positioned partially within the pipe, a proximal end of the rod attached to a distal-most plate and a distal portion of rod extending from the distal end of the pipe. A major face of each plate is configured to arrest sediment from water flowing into the pipe via a first water inlet while the holes defined by the plates enable filtered water to flow therethrough and out of the first water outlet when the first water inlet and first water outlet are opened. During cleaning of sediment, graywater flows into the pipe via the second water inlet and over the plates while a user moves the rod to dislodge sediment from the plates and toward an outlet.

A grease trap for separating waste from wastewater includes a tank having an outer wall, bottom and open top. An inlet invert in the tank receives incoming wastewater, and an outlet invert removes water from the tank. The tank has a cover on the open top, and the cover has a hatch. A barrier spans a diameter of the open top below the cover and has an opening vertically below the hatch. A divider divides the tank into an upper chamber and a lower chamber and has a hole for allowing FOG into the upper chamber from the lower chamber, the hole being colinearly aligned with the hatch and the opening in the barrier.

A liquid treatment device is configured to perform at least one treatment from a group of at least two different treatments. The liquid treatment device includes a connector defining an input conduit and an output conduit, a housing defining a closed-off space, and an adapter inside the housing. The adapter is moveable in the housing between at least a first position corresponding with a first liquid treatment and a second position corresponding with a second liquid treatment. A control is disposed outside the housing and connected to the adapter, and is configured to set the adapter from outside of the housing into one of at least the first position and the second position.

A sedimenting assembly for sedimenting debris contained in a processed waste liquid in a sedimentation tank includes a plurality of partition plates extending vertically across a direction in which the processed waste liquid flows and disposed at spaced intervals in the direction, thereby defining a zigzag channel through which the processed waste liquid flows horizontally. The zigzag channel ensures a time during which to sediment the debris against a time during which the processed waste liquid flows through the zigzag channel, allowing the debris to settle reliably.
