A tool and method clean and drain a water heater tank, removing water and sediment from the tank. An insert tube fits through the hot water outlet port to reach the bottom of the tank interior. A fitting connects the insert tube to a hose extending down the outside of the tank to the floor/ground to a drain or container that is lower than the bottom of the tank interior. After priming the tool by using the cold water inlet flow to fill the tool with water and sediment, the cold water inlet is disconnected from the water heater, venting the tank so that water and sediment are siphoned out of the tank through the tool to empty the tank. The tool and method work without unplugging or disconnecting a clogged water heater drain line, without using a compressor or pump, and without creating a wet, messy environment.

The invention relates to a water treatment line and a process for removing suspended solids, such as ferrous scale, and in particular also oils and greases, from cooling waters of metallurgical or steel processing. A sedimentation tank is included in which there is a lamellar pack filter with inclined sedimentation surfaces comprising a plurality of adjacent, essentially parallel and inclined tubular profiles, in particular with an angle of inclination with respect to the bottom of said tank of 50-65?. The application of the laminar packs in the tank which separate suspended solids, in particular ferrous scale, by sedimentation avoids the use of sand filters or the like.

A waste water separation vessel is provided having a wedge shaped body with an internal water containing volume. The body is configured to trap FOG and wastes within the body allowing water to pass through the body. At least one top facing access port to allow access to the internal volume of the body is provided and the wedge shaped body tapers outwardly from top to bottom to define a larger bottom area than a top area. The side walls include vertically oriented strengthening ribs which define intervening indentations, and each lower end of the vertically oriented ribs is connected to a generally horizontal beam which defines closed bottom ends on the indentations. When the vessel is buried in the ground the wedge shaped body and the closed bottom indentations interact with the ground to help oppose any buoyancy forces acting on the buried body.

A screen decanter for decanting liquid from a reservoir, comprising at least one rack comprising screens and baffles forming the sides of a cavity; a frame attached to the screens and baffles and providing a barrier so that liquid cannot pass from outside into the cavity without passing through the screens; a patterned perforated drain pipe inside the cavity and leading to an opening through which liquids may drain out from the cavity. The pattern of the openings counteracts the hydrostatic head within the rack such that flow through the screens is uniform at all depths of immersion in the liquid reservoir. Preferably, the screens have a porosity of about 50 micrometers.

A method of desalinating water through application of acoustic pressure shock waves to a slush to separate ice crystals from brine and recovering desalinated water from the separated ice crystals.

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 transportable separation apparatus for separating spent materials from oil and gas operations into a primarily solid component and a primarily liquid component. The separation apparatus includes a first separation area disposed on the separation apparatus for receiving spent materials and beginning separation of the spent materials. The separation apparatus designed to be connected to a vehicle to be pulled on commercial roadways. The separation apparatus also includes a second separation area in fluid communication with the first separation area for further separation of the spent materials. The separation apparatus can further include an auger in fluid communication with the first separation area to remove the primarily solid component from the separation apparatus. A method of introducing and separating the spent materials via the separation apparatus.

The present invention is directed to a clarifier for water treatment including a plurality of planar inclined sheets including a flexible polymeric material. Each sheet includes a hydrophobic surface. The present invention is also directed to a clarifier that includes at least one module, each module including: a plurality of vertically-oriented supports and a planar inclined sheet including a flexible polymeric material tensioned between the plurality of vertically-oriented supports. The present invention is also directed to a water collection system of a water treatment system including: a collection trough configured to receive liquid and a buoyant member configured to support the collection trough.

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 can split incoming water to pass into dual screen filtration systems. The system can include components selected from a shelf beneath the spreader, at least one baffle, skimmer, deflectors, media filtration and water pressure lines with spray heads for cleaning debris on a sloped floor.

The present invention relates to an environmentally friendly balanced waste water treatment system for diversified medical use, comprises a conditioning tank, a cleaning solution tank, a gas separator, a waste water lifting pump, a beveled wall sedimentation pool and a membrane filter device. The conditioning tank is connected to an external washing cloth waste water pipe. The conditioning tank is connected to the air separator and the waste water lifting pump, an output end of the waste water lifting pump is connected to the beveled wall sedimentation pool. The water treatment system of the present invention can break down hazardous materials in the waste water, does not cause secondary pollution, provides a good cleaning effect for medical waste water, complying with water treatment standard. It provides improved practicality and advancement, operation is stable, does not occupy a lot of floor space, layout is reasonable, production efficiency is high, operating life is long, ensuring long trouble free operation time.
