Method of Recovering Potassium from Waste Waters for Use in Purification of Waste Water, including the Waste Water from which the potassium is Recycled, while retaining the Potassium in forms suitable for use as a Nutrient in Growing Microbes, Plants and Algae

Номер: US20120061315A1
Автор: Gerald J Grott
Принадлежит: Individual

A method for recovering and/or utilizing potassium from waste waters for a plurality of applications. As algae and plants are able to survive and flourish in environments with high salt concentrations, waste waters containing potassium can be applied as fertilizers to the growth of microbes, algae and plants. The microbes, plants, and algae are able to absorb the necessary nutrients, such as nitrogen and potassium, from the waste waters. After depletion of the potassium content from the waste water, that waste water can then be treated to separate other contaminants. In another aspect of the present invention, the potassium content may be first separated from the waste water to be applied for growth of microbes, plants, and algae and again used for regeneration of cation resins in specific potassium forms. The remaining contaminants that are separated through treatment of the waste water can be utilized for different productions.

A swimming pool cleaner of the type movable along an underwater pool surface to clean debris therefrom. The pool cleaner includes a body having a debris inlet and a debris outlet. A rigid debris-collection canister is secured to the body over the debris outlet to collect debris in the rigid canister and pass filtered water either back into the pool or to a remote suction system such that the collected debris remain at the pool-cleaner body for easy maintenance while allowing free flow of water through the rigid canister. The rigid canister is shaped to minimize obstructions to the pool cleaner movement in the pool by providing improved buoyancy and limiting entrapment of the cleaner by underwater pool structures. The cleaner body is adapted for securement of either a water-suction hose connected to a remote suction system or a venturi-line structure connected to a water-flow line fed by a remote pump such that the pool cleaner is interchangeably usable as a suction cleaner and as a pressure cleaner.

The invention relates to a process for the treatment of a used waste alkali, in which the used waste alkali is oxidized at a superatmospheric pressure in the range from 60 bar to 200 bar. The pressure of the used waste alkali L is increased and then heated by indirect heat exchange. The heated used waste alkali is conveyed into a separator, wherein vaporized aqueous phase is separated from the used waste alkali. The resultant liquid phase is brought to the desired reaction pressure and introduced into an oxidation reactor. In the oxidation reactor, the used waste alkali is oxidized. In a first reaction, thiosulphates are formed from the sulphides. In a second reaction, the thiosulphates are converted into more stable sulphates.

Wetland Biofilter Chamber with Peripheral Catch Basin and Method of Use Thereof

Номер: US20120091057A1
Автор: Greg B. Kent, Zach J. Kent
Принадлежит: Individual

A horizontal flow water treatment method and wetland biofilter apparatus provides a chamber with impermeable outer walls spaced away from permeable interior walls of a media filtration bed such that a catch basin is formed between the outer walls and the interior walls. The catch basin creates an open area around the perimeter of the interior walls for influent water to fill within the open area on all sides before penetrating the filtration media, providing a large surface area for influent water to interact with the media filtration bed. The influent water enters the catch basin in a horizontal flow path to provide for pre-settling of particulates before making contact with the filtration media. The biofilter design increases the available surface area of the media filtration bed by up to four times for a given volume of water, and thereby minimizes the loading or infiltration rate on the media filtration bed.

Process, method, and system for removing heavy metals from fluids

Номер: US20120125816A1
Автор: Darrell Lynn Gallup, Dennis John O'rear, Lyman Young, Sujin Yean
Принадлежит: Chevron USA Inc

Trace element levels of heavy metals in crude oil are reduced by contacting the crude oil with an oxidizing agent, extracting heavy metals into a water phase for subsequent separation from the crude oil. The oxidizing agent is selected from the group of hydroperoxides, organic peroxides, inorganic peracids and salts thereof, organic peracids and salts thereof, and ozone. In one embodiment, the oxidizing agent converts heavy metals into the heavy metal cations in a water-oil emulsion, which can be subsequently separated from the crude oil, for a treated crude oil having reduced levels of heavy metals. In one embodiment, at least a complexing agent can be added to facilitate the removal by forming soluble heavy metal complexes in the water phase.

Method for recycling deoiled water using counterflow falling-film evaporators

Номер: US20120145386A1
Автор: Chandrakant Tiwari, Daniel P. Bjorklund, David Kersey, Gregory J. Mandigo
Принадлежит: Aquatech International Corp

We provide an evaporator technology for treatment of produced water that may be deoiled water. Systems described herein utilize a vertical tube heat exchanger bundle where the brine is distributed in a falling film along the inside of the tube wall. Condensing steam causes a portion of the deoiled water to evaporate; this water vapor travels upward in a counterflow direction relative to the deoiled water. This evaporator technology provides several design advantages over the conventional vertical tube co-current flow evaporators (where the vapor flows downward with the falling film). These advantages include a minimal total installed cost (TIC) as well as offering optimal design features for water chemistry management.

A process for drying fine tailings is provided. The process, which may use a pipeline reactor system, comprises providing an in-line flow of the fine tailings; continuously introducing a flocculent solution to cause dispersion and commence flocculation of the fine tailings and may comprise rapid turbulent mixing; subjecting the fine tailings to flocculation and water release conditioning in-line to cause formation and rearrangement of floes and increasing the yield shear stress to form flocculated fine tailings while avoiding over-shearing of the flocs; and depositing the fine tailings to allow the release of water, formation of a non-flowing fine tailings deposit and drying of the non-flowing fine tailings deposit. The process enables effective in-line dispersion, flocculation and water release, resulting in reliable deposition and drying of the fine tailings deposit.

Methods for the treatment of ballast water

Номер: US20130056648A1
Автор: II Richard W. Fahs, Matthew D.W. Fahs
Принадлежит: Fahs Stagemyer LLC

A process has been developed to selectively dissociate target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism. This process can be used for the remediation of water, particularly ballast water.

A reverse electrodialyzer has a plurality of concentrated compartments and diluted compartments arranged alternatively. The concentrated compartments and the diluted compartments are formed by successive alternatively arranged oppositely charged ion exchange membranes between two electrodes. A brine solution is fed into the concentrated compartments, and a diluted solution is into the diluted compartments, the salinity of the diluted solution being lower than the salinity of the brine solution. Ions from the brine solution in the concentrated compartments pass through the membranes to the diluted solution in the diluted compartments forming a diluted brine solution in the concentrated compartments. The brine solution is extracted from the concentrated compartments for disposal. An electrical energy is produced due to the concentration difference of the brine solution and the diluted solution.
