An extrusion system for separating particulates entrained in wash water, e.g. from harvesting tuberous produce, includes a settling tank configured to receive a flow of particulated water. A diffuser suspended within the tank converts the flow of particulated water into multiple transverse flows to avoid churning settled particulates. A particulate filter fixed within the tank includes a central channel surrounded by a cylindrical array of cantilevered parallel vertical blades. The channel directs the flows below the blades, causing dynamic movement of the blades as the particulated water rises therebetween to trap particulates along boundary layers, promote particulate settling by gravity, and allow clarified water to rise to the top of the tank. A sensor detects settled particulate reaching a predetermined setpoint, and in response the system actuates an auger and opens a pinch valve to force concentrated particulate from the bottom of the tank.

Methods and systems for removing pollutants from water include one or more filter systems and a hybrid wetland system. Hybrid wetland systems may include a first pipe transporting water from a body of water to a settling tank, a first constructed wetland connected to the settling tank via a second pipe, and a first filter system removing pollutants from water passing through the second pipe. A second filter system is positioned within the first wetland to further remove pollutants. The system also includes a second constructed wetland connected to the first constructed wetland via a third pipe and a water control chamber. Filtered water exiting the first constructed wetland flows through the water control chamber, through the third pipe, and into the second constructed wetland. A fourth pipe extends between the second constructed wetland and the body of water, returning filtered water to the body of water.

A passive filter cell having a basin with a floor and two or more vertical or upright sidewalls forming chute or container having first or left sidewall, second or right sidewall, and third or back sidewall, and fourth or front downwardly curved sidewall, an inlet positioned proximate a top of the fourth or front sidewall and an outlet positioned proximate the top of the third or back sidewall, wherein the floor is configured angled from the fourth or front sidewall to the third or back sidewall, discharge pipe positioned proximate junction between the floor and the third or back sidewall, and lip configured to extend from the top of the third or back sidewall into an interior of the basin.

Defluidizing tanks may include a tank having an interior defined by side walls and a bottom; a filter assembly emplaced within the interior of the tank and constructed to receive a slurry of solids and recovered fluid; and a weir chamber within the tank and defined by the interior of the tank and at least one wall of the filter assembly. Systems may include a source of recovered fluid from a wellbore operation; a filtration unit receiving the recovered fluid and isolating a fraction of solids from the recovered fluid, the filtration unit having a backflush mode in which the fraction of solids is evacuated from the filtration unit; and a defluidizing tank receiving the evacuated fraction of solids to generate a filtrate and dried solids.

A method of activating and dewatering sludge through application of acoustic pressure shock waves to wastewater.

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.

A solar powered sediment capture system is disclosed for collecting sediment at environment sites such as lakes and rivers. A mechanical pump directs water from a containment basin to an upper tank and an antistatic pressure tank, both which are elevated. Gravity flow from the upper tank generates vacuum to establish a syphon for drawing a flowable sediment slurry from an environmental borrow site to a filter. Effluent from the filter passes down to the containment basin, which has water level at a lower elevation than that of the borrow site. Anti-static and driller conduits permit gravity flow from the anti-static tank to suspend the sediment and to maintain the slurry at the syphon inlet in a flowable state.

A turbulating apparatus for a drywell includes a frusto-conical sidewall having an upstream inlet and an opposed downstream outlet. The sidewall has an inner surface on which a plurality of vanes are fixed and extend helically between the inlet and outlet. The apparatus hangs from a top of the drywell and turbulates water to prevent the aggregation of debris inside the drywell.

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 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.
