A transportable multi-chamber water filtration system useable at construction sites with sources of contaminated water is disclosed. The transportable multi-chamber water filtration system removes sediment and contaminants from contaminated water by combined processes of gravitational settling, filtration and coagulation of sediment by the use of flocculants. The system provides efficient removal of sediment and contaminants from the water around various sized sites.

An apparatus for removing sediment from a pond includes: a handle; a vacuum unit connected to the handle, said vacuum unit having a first opening adapted for receiving material sucked into said opening and a second opening for material sucked into said vacuum unit to exit at a point outside said pond, said vacuum unit being submersible, supported by at least one wheel, and having an aperture for receiving a mixture from a bottom of the pond; a hose associated with said second opening; and a storage container, said storage container having a body and a storage film cartridge adapted to be positioned in said body, said cartridge having storage film therein, said storage film being permeable to water and having a mesh, and a sealing mechanism having an actuator operably connected to said cartridge, wherein actuation of said actuator rotates said cartridge causing said storage film to seal.

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.

An emergency treatment device for algal blooms in reservoir tributaries and bays includes a hull, an automatic detection unit provided on the hull, an algae collection-separation unit, an ultrasonic algae removal unit, a micro-current electrolytic algae suppression unit, an algaecide adding unit, a power unit and a control unit. The automatic detection unit, the algae collection-separation unit, the ultrasonic algae removal unit, the micro-current electrolytic algae suppression unit, the algaecide adding unit and the power unit are connected with the control unit. The algae collection-separation unit is used for suction and ex-situ treatment of high-density algae on a surface of the water body. The ultrasonic algae removal unit, the micro-current electrolytic algae suppression unit and the algaecide adding unit are used for in-situ treatment of algae in the water body.

A cost-effective system and method dissolves gas, such as oxygen, into water in a manner that prevents gas bubble carry over by using a bubble capture system (BCS). The system and method further eliminates or minimizes turbulence at the suction and discharge of a pump using an energy dissipation header (EDH). The BCS can create a top-down flow that permits bubbles to rise faster than the velocity of the downward flow of water. The EDH can use a pipe design, such as a slotted pipe design, that permits a maximum system water flow. The technology can be applied to water bodies to mitigate eutrophication and may also be applicable in other fields, such as wastewater lift stations, fish farms, oil and gas industry, tidal applications with low flushing rates, and winter under ice oxygenation to prevent fish kills.

A water treatment method includes: withdrawing water from the environment; filtering the withdrawn water in a membrane filtration unit; extracting a production flow from an underground formation containing hydrocarbons; separating and collecting production water from the production flow; filtering the production flow in the membrane filtration unit; collecting a treated water flow from the membrane filtration unit. An installation adapted for applying this method is also provided.

An apparatus, system and method to purify water is disclosed. Pumps and energy recovery devices for taking water from an intake, filtering the water to remove solid contaminates before running the filtered water through the reverse osmosis system to the discharge device and purified water lines are described. The system may comprise a control panel that controls the plurality of filters, plurality of reverse osmosis membranes, purified water line and effluent discharge device, to achieve favorable water purification. A method that utilizes the apparatus and/or system is described herein.

A pleated filter includes a filter base having folds that repeatedly form mountains and valleys and having a cylindrical shape whose axial direction is a ridge line direction of the folds. The pleated filter includes, in a valley projecting to the inside of the cylindrical shape, a bonded reinforcing portion extending in the ridge line direction of the folds.

Provided are systems and methods for treating wastewater with a continuous-process mobile station. The mobile station may include one or more mobile units configured to receive a feed of wastewater. The one or more mobile units may include: a mobile ozonation unit configured to treat the received feed of wastewater with ozone gas to breakdown impurities in the wastewater, a pH control unit may be configured to raise pH of the treated wastewater, a mobile electrocoagulation unit configured to separate solids and metals from the treated wastewater, a mobile flocculation unit configured to cause suspended particles to form flocs and to remove the flocs from the received treated water.

A water desalinator that employs the use of solar concentration, evaporation and humidification, mimicking the natural hydrological cycle in a closed, modular vessel to produce freshwater from salt, brackish, brines and seawater, and a concentrate stream for further processing. Feed water is received and stored in a basin. Surface humidity is generated by the evaporation of basin water. A lens is used to focus sunlight, tracked the suns path based on biomimicry of a sunflower, on a thermal conductor. The thermal conductor has a rounded side-profile and generates a variable temperature across its radius. Water is pumped from the basin to a sprinkler head to be dripped or sprayed on the thermal conductor to generate water vapour. This water vapour consequently mixes with the air in the reaction vessel to increase system humidity. Humid air is removed from the reaction vessel and condensed in a condenser. Accordingly, the salinity concentration of input water is reduced from the output of the reaction vessel. Multiple reaction vessels or concentrators may be used in tandem to achieve improved performance.
