Devices, systems, and methods for separating solids from liquids are disclosed. A vessel includes an inlet, a carrier liquid outlet, a product outlet, a purifying section, and a heater. The inlet directs a slurry into the purifying section. The slurry comprises particles of a solid and a carrier liquid. The purifying section preferentially drives the particles of the solid towards a heating zone of the purifying section versus the carrier liquid. This displaces a first portion of the carrier liquid away from the heating zone of the purifying section. The heater heats the slurry. The carrier liquid outlet drives a majority of the carrier liquid out of the vessel. The product outlet is adjacent to the heating zone of the purifying section.

Device (200) for cleaning grey water containing particulate material, comprising a container (201) in turn comprising a water entry (202); a slurry exit (204); a cleansed water exit (203); and a sedimentation volume (220). The invention is characterised in that the container further comprises a flocculant provision means, arranged to add a flocculant (212) to grey water entering via the water entry, so that grey water having entered said sedimentation volume after such adding contains said flocculant, in that the flocculant provision means comprises a vertical chute (213) arranged to convey, via gravity, said grey water from an upper part of said container to be released via an open lower end (215) of the chute into said sedimentation volume at a height of at the most 1 m above a bottom (221) of said sedimentation volume, the chute having a cross-sectional area of at least 0.1 m2. The invention also relates to a method.

Device (100) for cleaning grey water containing particulate material, comprising a contain-er (101) in turn comprising a water entry (102); a water exit (103); and a slanted separation wall (150,160) separating an upstream sedimentation volume (120,130) of said container from a downstream sedimentation volume (130,140) of said container, the separation wall comprising a through channel (151,161) having a lower outlet (153,163), via which water can flow, by gravity, from said upstream sedimentation volume to said downstream sedimentation volume. The invention is characterised in that the container further comprises a flocculant provi-sion means (110), arranged to add a flocculant (112) to grey water entering via the water entry, so that grey water having entered said upstream sedimentation volume after such adding contains said flocculant, and in that said lower outlet is shaped to direct a flow of water flowing downwards through the through channel obliquely upwards upon entry into the downstream sedimentation volume. The invention also relates to a method.

A stormwater filter comprising: a vessel having an inlet and an outlet; and a screen disposed within the vessel and arranged to divide at least part of the vessel into an upper section and a lower section. The stormwater filter further comprises: a flow splitter positioned adjacent the inlet of the vessel and/or a substantially vertical screen disposed adjacent the outlet in the upper section of the vessel. The flow splitter comprises an inclined leading edge and first and second deflecting surfaces extending from the leading edge. The first and second deflecting surfaces are angled relative to one another so as to direct incoming flow laterally away from an axis between the inlet and the outlet. The vertical screen comprises first and second screen portions which are angled relative to one another. The first and second screen portions are each hingedly connected to the vessel and are detachably coupled to one another at their distal ends.

An enhanced flocculation influent feedwell assembly for water and wastewater treatment clarifiers is configured for being disposed about a riser of a clarifier and from which riser pipe a liquid enters the influent feedwell. The influent feedwell has a floor region having an opening and a sidewall region. A plurality of preferably arcuately shaped fins are disposed on the floor region in a circular pattern around the opening in the floor region and have a height which is generally equal to a height of the sidewall region. A plurality of preferably non-arcuately shaped fins are periodically disposed on the sidewall of the influent feedwell in a spaced apart manner and have a height which is less than the height of the sidewall region. The plurality of non-arcuately shaped fins are disposed such that they are spaced apart from and do not contact the floor region of the influent feedwell.

A liquid reclamation and recirculation system for a wet saw cutting apparatus comprising: a wet saw having a blade onto which liquid is dispensed by a liquid dispenser adjacent thereto; a first tank for receiving the liquid that has been dispensed onto the blade, the liquid received by the first tank defining a water level of the first tank; a second tank for receiving the liquid at or near the water level of the first tank; wherein the liquid dispensed by the liquid dispenser is drawn from the second tank.

Vaults, boxes, systems, and methods of treatment systems to capture pollutants from storm water runoff and prevent the conveyance of these pollutants from entering a receiving water body or landscape area, which is designed to be a part of a local permanent storm water drainage infrastructure. A single treatment box, vault and system combines both drainage conveyance, multi-level treatment techniques, variable hydraulic capabilities, and easy and inexpensive methods for servicing the system. A flow spreader having a triangular shape with straight sides, or concave sides or convex sides can split incoming water to pass into dual screen filtration systems. Additionally, an upwardly angled debris ramp above a downwardly angled screened defector can be located on both sides of the flow spreader to help direct debris and trash into dual screened boxes. The system can also include components selected from a shelf beneath the spreader, at least one baffle, skimmer, deflectors, media filtration and hydroslide water pressure lines with spray heads for cleaning debris on a sloped floor.

A method, system, and apparatus directed to an innovative approach for the treatment of stormwater utilizing hydrodynamic separator assembly designed to maximize flow movement for more efficient sediment removal and maximize clearance space within assembly to facilitate cleaning and increase storage capacity of trash, debris, and sediment.

A method can include providing at a location remote from a tank of a pre-existing separation facility an induced gas separation unit including a pump and an eductor, then transporting the induced gas separation unit to the separation facility, then connecting the induced gas separation unit to the tank, and then operating the induced gas separation unit, thereby pumping gas into a fluid composition in the tank. A system can include an induced gas separation unit with a pump and an eductor mounted to a portable structure, a line providing fluid communication between a pump inlet and the fluid composition in at least one tank, a line providing fluid communication between the eductor and a gas in the tank, and a third line providing fluid communication between an eductor outlet and the fluid composition in the tank.
