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.

Vapor and liquid flow concurrently down through a vertical vessel. A horizontal scale collection and predistribution tray is located in the vessel to remove solid contaminants and to redistribute the liquid to a fine distribution tray. The scale collection and predistribution tray consists of a tray plate with a scale collection zone where the solid contaminants settle and deposit. In one embodiment, an upstanding permeable wall forms the scale collection zone, and liquid is filtered as it flows through the permeable wall, leaving the solid contaminants trapped upstream from the permeable wall. The predistribution tray has a rim provided with a slotted weir. Liquid from the scale collection zone forms a liquid level in a trough located between the permeable wall and the weir. Due to the uniform liquid level in the trough, liquid flow rates through the slots in the weir are nearly equal. Because of the polygonal shape of the tray, the liquid exits the slots in a direction along lanes defined between distribution units on the fine distribution tray, and the amount of liquid entering the vapor inlets of the distribution units is therefore small. Vapor by-passes the scale collection and predistribution tray through the area between the reactor wall and the permeable wall, and through the area between the reactor wall and the weir to the fine distribution tray. The scale collection and predistribution tray protects the fine distribution tray and the catalyst bed from fouling, predistributes liquid to the fine distribution tray to minimize level gradients on this tray, and reduces flow velocities to ensure calm flow conditions on the fine distribution tray.

Method and apparatus are provided for treating salt water. In the method, a feed water is run through a skimmer unit to form de-oiled water. The de-oiled water is passed through an electrocoagulation unit to form electrocoagulated water. A precipitating agent is added to the electrocoagulated water and stirred to form a water/floc mixture. A polymeric coagulation enhancing agent is added to the water/floc mixture with mild stirring and coagulants in the mixture are permitted to settle. A partly clarified water from the mixture is drawn out from a level above the settled coagulants. The partly clarified water is run through at least one settler and coagulants are removed from the bottom of the at least one settler. A clarified salt water stream is withdrawn from the final settler. The necessary equipment can be mounted on a trailer. The trailer can be provided with a stairway and catwalk to facilitate safe inspection.

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.

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.

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. In particular, the described hydrodynamic separator is an improvement over other hydrodynamic separators known in the art with the inclusion of one or more down pipes which siphon water from the lower portion of the sump chamber. The inclusion of down pipes allows for an improved control of the velocity of the water flow through the device by distributing flow into more than one path.

Process for producing a suspension by precipitation of a solid from a solution, wherein at least two solutions of salts are combined with one another in a stirred vessel so as to form a sparingly soluble solid, where portions of suspension are taken off continuously or discontinuously, the portions taken off in this way are processed in a combination of two separation apparatuses, where gas is separated off in a first separation apparatus which is selected from liquid-gaseous separation apparatuses, and mother liquor is separated off from precipitated sparingly soluble solid in a second separation apparatus selected from solid-liquid separation apparatuses, and the mother liquor is taken off, and the solid which has been separated off or enriched in this way is returned to the reaction mixture.

An oil-water separator for separating mixed density fluids, such as oil and water, oily sediment laden water and the like, as well as portable, in-tank and towable and anchorable boom containment systems kits and methods employing the same. The oil-water separator employs at least two oil-separation chambers operating in opposing but synergistic separation modes in parallel. The oil-separation chambers alternate distribution of a single mixed fluid density stream between the chambers using a partial vacuum source to draw the stream into one chamber, while concurrently stopping inflow of the stream into another chamber by removing the vacuum source. The apparatus allows each chamber to switch back and forth between (a) actively separating and removing less dense fluid (e.g., oil) when the partial vacuum is applied, and (b) passively separating the less dense fluid (e.g., oil) and removing the more dense fluid (e.g., water) when the partial vacuum source is removed. The oil-water separator can be adapted for multiple different uses, including rapid deployment cleanup kits that are sufficiently lightweight and compact for easy transport, access and application.

The invention involves a vibrating inclined plate box settlement separator, which is used for the liquid-solid separation, particularly applicable to high-efficiency settling concentration and separation of solid particles from liquid or water. The separator consists of an upper box and a lower tapered hopper. The upper box and the lower tapered hopper are connected securely to each other and sealed. The upper box is a rectangular or square steel-structured box with two supporting platforms on both of its sides, on which several spring assemblies are installed. The inclined plate box modules which can independently vibrate are installed on the spring assemblies. The feed box is placed on top of or inside the upper box. An overflow collect chute is welded on the side of the box frame opposite to the feed box.
