Tertiary wastewater treatment wherein a tank is divided into a primary separation chamber, an aerobic chamber, and a clarifier chamber. Media are preferably disposed in the aerobic chamber and most preferably, the media can be contained in one or more porous containers. A recirculation path is preferably provided between the aerobic chamber and the primary separation chamber. In one embodiment, the recirculation between the two chambers can be powered by an air lift pump.

The present invention comprises an impurities or materials trapping apparatus for separating or trapping a selected or unwanted materials such as sediment in a pourable material having sediment therein. The apparatus comprises a body having side walls between a first end and second end defining at least a recessed inner space 42, 104, 204, 286 there between for a pourable material. The apparatus includes at least one raised portion 50, 51, 55, 56, 206, 208 having a highest point, angled walls 26 connected to the side walls 7, 40 202, 220, 282 and at least one drainage aperture 16, 110, 210 located within the side walls 7, 40, 202, 220 282 or angled walls 26, 103, 203, 284. The raised portion is located at one end of the inner space and the angled walls 26 are located at a spaced distance from the raised portion. In one orientation of the apparatus, the side walls or angled walls drain at least a portion of the pourable material towards and though the drainage aperture and down to the raised portion and in another orientation of the apparatus, the drainage aperture is blocked thereby retaining any sediment. The apparatus of the present invention can be formed as part of a container or bottle and/or be part of a cap assembly. Methods of operation are also included.

A mobile flocculation and water treatment system includes at least one tank, preferably a series of adjoining tanks separated by weirs, and an adjacent pump house mounted on a mobile platform. At least one pump is mounted in the pump house. Fluid conduits run from the pumps to the tank. An overflow is mounted between the downstream tank and the pump house whereby fluid overflow from the tanks is directed into the pump house. The pump house provides a substantially water-tight reservoir zone to provide secondary containment. Water to be treated enters the upstream end of the tanks and is discharged from the downstream end.

A modular system for reducing the total suspended solids of waste, including scum, sludge and water layers, includes a plurality of chambers each being connected in succession by a corresponding one of a plurality of flow pipe segments including an inlet segment, an outlet segment and at least one middle segment, wherein the waste enters the septic tank via the inlet segment and is transferred between each of the plurality of chambers via the at least one middle segment; a corrugated flow pipe in fluid flow communication with the outlet segment; and the corrugated flow pipe being sized and configured for use as a settling zone for removal of a portion of the total suspended solids and wherein an amount of water from the water layer within the chamber adjacent the outlet segment enters the corrugated flow pipe and passes through the outlet segment.

A mobile water re-use system can include a chemical treatment apparatus, at least one weir tank in fluid communication with the chemical treatment apparatus, and two or more settling tanks in fluid communication with each other and at least one of the settling tanks in fluid communication with the weir tank. The weir tank can have a first end, a second end, an internal chamber, and a plurality of baffles that induce turbulent flow of fluid through the internal chamber. The settling tanks can provide, promote, facilitate, result in, and/or induce laminar flow of fluid through at least a portion of the internal chamber. Weir tanks, settling tanks, and method of treating flowback and produced water are also described.

In one embodiment, the windshield wiper fluid refilling system includes a removable filter configured to receive fluid through a first opening from outside an automobile. The removable filter includes one more filtering components therein for removing contaminants from the fluid. A reservoir is configured to couple to the removable filter and receive the fluid from the removable filter through a second opening formed therein. The reservoir including a pump inlet configured to pump the fluid from the reservoir to a windshield of the automobile. The windshield wiper fluid refilling system allows the wiper fluid to be refilled without needing access to the hood of the automobile.

An aerobic treatment/clarifying system for use in an aerobic wastewater treatment system. The system comprises a structure which defines at least one compartment, at least one aerobic treatment chamber and at least two clarifying chambers being formed in the compartment.

The present disclosure provides a sedimentation tank capable of automatically adjusting liquid level and flow, which comprises one or more sedimentation cells which are connected in sequence, a water inlet pipe is arranged on the left side of the leftmost sedimentation cell; the front end of the water inlet pipe is bent and the input port of it is close to the wall; the highest point of the connecting pipe is lower than the highest point of the grease discharge port of the corresponding sedimentation cell, when the liquid level in the sedimentation cell reaches the discharge level of the connecting pipe, the connecting pipe automatically adjusts the flow according to different discharge level so as to adjust the liquid level of the sedimentation cell, and the settled sewage is discharged out of the tank or discharged into the next-stage sedimentation cell until the last stage, and finally discharged. The sedimentation tank has a compact and attractive structure and high space utilization, and different connecting pipe structures can be selected specifically, so as to change the capacity of adjusting the liquid level and flow of the sedimentation tank, and the sewage separation effect is thorough.

The present invention supplies partitioned water treatment systems that possess a plurality of chambers and vertical filtration units, and are operative to control and filter surface runoff water. Such systems are typically placed inline with surface runoff water conveyance system infrastructure, such as pipes, channels, and water storage units.

A mobile flocculation and water treatment system includes at least one tank, preferably a series of adjoining tanks separated by weirs, and an adjacent pump house mounted on a mobile platform. At least one pump is mounted in the pump house. Fluid conduits run from the pumps to the tank. An overflow is mounted between the downstream tank and the pump house whereby fluid overflow from the tanks is directed into the pump house. The pump house provides a substantially water-tight reservoir zone to provide secondary containment. Water to be treated enters the upstream end of the tanks and is discharged from the downstream end.
