An in-line fitment for connection of a filter to a pipe includes first and second fluid-carrying portions and a non-fluid-carrying spacer. Each fluid-carrying portion includes a socket for receiving an open end of a pipe and a connector for connection of the filter. A screw compression fitting is provided on each of the sockets of the first and second fluid-carrying portions for forming a sealed connection with the open ends of the pipe. The socket of the first fluid-carrying portion has a pipe receiving depth greater than that of the socket of the second fluid-carrying portion for enabling movement of the fitment parallel to the pipe when engaged with one of the open ends of the pipe. The sockets of the first and second fluid-carrying portions are positioned on a common axis and facing away from each other when the fluid-carrying portions are linked by the spacer.

A liquid cleaning and watering system for living plants rests on a surface covered by a non-porous material. A plate layer covering the non-porous layer has two or more layers, each layer having runners arranged in a grid. The grid of each successive layer is offset at an angle with respect to the grid of a previous layer. An upper layer covers the plate layer and has a plurality of holes for the passage of liquids into the liquid cleaning system. As the living plants are watered or cleaned, excess liquids containing water and oils that were excreted by the living plants enter the liquid cleaning system through the holes, the liquid traverses the grid layers, flowing towards a drain. Contaminants within the liquid collect within the grid of the layers of the plate layer for later disposal.

A cover for a liquid containment apparatus includes: a platform having a top surface, a first end, a second end opposite the first end, and two opposing sides that extend between the first and second ends. The cover also includes: a front wall extending down from the first end of the platform; a back wall extending down from the second end of the platform; side walls extending down from the opposing sides of the platform; and engagement members extending out from a bottom of the side walls in a lateral direction from the platform and which are configured to engage a surface of a substrate. The platform includes a plurality of holes, and the side walls include a plurality of notches that form a weir for distributing liquids. A liquid containment system is also included.

A tank system may be conventional and fixed, or mobile, such as a fracking fluid or other tank trailer. A drain port thereof is fitted with an adapter connecting a snorkel system to drain liquids from near the top of the liquid level in the tank. A snorkel head at the extreme distal end of a tube near the longitudinal center of the tank is suspended by a system of buoys. A flow field controller plate resists formation of vortices near the snorkel head, so it can operate as near the surface as possible, withdrawing the highest grade oil efficiently. At its exit, the proximal end of the tube drains oil through an inner conduit of an adapter at a penetration in the wall of the tank. The adapter forms an annulus around the inner conduit draining tank bottoms directly from the tank.

A compact extractable self-contained decanter that is sealed for powered suction of supernatant from a wastewater tank without clogging from filters.

An apparatus and method for trapping particles disposed in a fluid. The apparatus may comprise one or more cavities disposed axially along a length of a tubular housing, one or more connecting components disposed at opposing ends of the housing, and may optionally comprise a check valve system. Alternate embodiments are provided for forming each of the one or more cavities, which may comprise a combination of a cavity frame and cavity surface. The method may comprise flowing a fluid into a first end of a particle trap apparatus at a rate of fluid flow, directing the fluid flow at least partially through one or more cavity sub-assemblies disposed in the particle trap apparatus, collecting the particulate matter in one or more of the cavity sub-assemblies when the rate of fluid flow may slow or become suspended, and clearing collected particles from the one or more cavity sub-assemblies upon restoration of fluid flow in a primary direction of travel.

A clarifier can comprise a floor, inner and outer walls that each extends upwardly from the floor such that a tank is at least partially defined by the inner wall and a launder channel is at least partially defined between the inner and outer walls and is disposed along at least a majority of a periphery of the tank. A launder cover comprising one or more flexible sheets can be disposed over at least a majority of the launder channel. Each of the sheet(s) can have opposing inner and outer edges, the inner edge coupled to the inner wall and the outer edge coupled to the outer wall, and can be configured such that, when a single one of the inner and outer edges is decoupled from the inner and outer walls, the sheet is deformable to at least partially uncover the launder channel.

Provided is a liquid processing apparatus and a liquid processing method for reducing a waste amount of a high specific gravity liquid. The liquid processing apparatus includes: a supply pump; a bubble tank including an inflow port, an overflow port, and a return port; a microbubble generator disposed outside the bubble tank; a recovery tank having a recovery port to recover the processing liquid overflown from a first liquid level to the tank; a separation tank including a settling tank connected to the overflow port, and a floating tank connected to the settling tank at a lower portion, and an ejector having a inlet port connected to the supply pump, a suction port connected the suction body, and a discharge port connected to the return port.

The present development is a septic tank or wastewater treatment tank outlet filter cleaning device. More specifically, the device is an outlet filter cleaner for a slotted filter used to reduce solid waste transfer into a septic tank effluent. The device comprises a central shaft with at least one cleaning disc, wherein the cleaning disc comprises a body which is mounted on the shaft and wherein a plurality of fingers protrude from the body, preferably in locations substantially identical to the positions of the openings in the wall of the tube.

A sedimentation device for separating a solid-liquid suspension has a settling tank, a feed well, a feed pipe, an overflow collector and a mixing area. A pump is disposed in the overflow collector and overflow from the overflow collector can be fed through the pump to the mixing area. The solid-liquid suspension to be clarified can be diluted without affecting the sedimentation process, the chemicals can be used to the optimum, and the amount of overflow fed to the mixing area can be exactly determined.
