The process facilitates storage of the moulded bodies and also may be used to sterilize the water or sludge or improve its filterability. Chlorophenols or aliphatic halogen compounds present in the waste water may be decomposed by the process. To assist this decomposition, there may be added isopropyl alcohol, a halobenzene, halophenol, haloanisole, or polyhalobiphenyl or an olefinic halogen compound, e.g. trichloroethylene, tetrachloroethylene, or hexachlorobutadiene. The decomposition is also assisted by passing a stream of air through ...

An apparatus subjects water to waves from an RF plasma. This allows continuous production of "activated water" characterized by cluster sizes below about 4 molecules per cluster, water having pH below 4 or above 10, or water having ORP of less than -350 mV or more than -t- 800 mV. The basic frequency of Ihc plasma is preferably between 0.44 Mil/ and 40-68 Mil/, and the plasma is preferably modulated at a frequency between 10 kHz and 34 kHz. Flow rales typically range from 20 1/hr to about 2000 l/hr. Activated water can be used for many purposes, including antimicrobial cleaning of worktable, floor, wall, knife, transport and other surfaces, for example, in meat processing facilities and hospitals.

Development of solar driven photocatalyst and its application in degradation of organic pollutants Abstract In this project, core-shell CdS@SnO2 particles have been prepared by Successive Ion Layer Adsorption and Reaction (SILAR) method. CdS is a well known low band gap semiconductor (of band gap ~ 2.4eV) and can thus harvest visible light of wavelength up to 520nm of the solar radiation. In our present work, we have implemented SILAR method with slight modification to coat thin CdS layer over fine SnO 2 particles to obtain core-shell CdS@SnO 2 particles. The SILAR method, which is usually used for the deposition of binary semiconducting thin films, has some advantage over other preparative methods, for example, this is a facile, less expensive and less time consuming technique, and it provides the provision to control the thickness of the film by adjusting the number of cycle of coating. In the present synthetic approach, fine SnO 2 powder has been prepared by hydrothermal method initially ...

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.

An advanced water treatment method processes a continuous flow of water in a sequence of stages including pre-filtering [ 200 ] to remove solids, conditioning [ 202 ] to adjust pH, blending [ 210 ] with a recycled dense microalgae culture, and passing the resulting mixture through an enclosed, environmentally-controlled photobioreactor [ 212 ] where nutrients, PCB's, trace metals and other pollutants and regulated compounds are taken up by the algae. The flow from the PBR is separated using cross-flow filtration [ 222 ] to produce a treated water flow and a dense microalgae flow that is recycled to the blending stage [ 210 ] upstream. Thus, whereas the algae is recycled, the water entering the system is treated by flowing sequentially through the stages of the system, without any recycling or repetition of treatment stages.

Systems and Methods for the Treatment of Ballast Water

Номер: US20130213899A1
Принадлежит: Fahs Stagemyer LLC

A system has been developed to treat ballast water by selectively dissociating 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. 1. A precise energy separation chamber for water remediation comprising:a chamber having one or more inlet ports and one or more outlet ports, andone or more energy of dissociation sources,wherein water is capable of flowing into the chamber through an inlet port, in proximity to an energy of dissociation source, and flowing out of the chamber through an outlet port, andwherein the energy of dissociation source can provide an effective amount, intensity and frequency of energy to specifically dissociate one or more target bonds in the target molecules in the water to separate the target molecules into their component products without producing any reaction by-products and without re-association of the one or more target bonds.2.

The present disclosure deals with is a combination of interconnected innovative technologies for exploiting the advantages of closed cyclic chain reactions on a global scale to solve the contemporary problem of carbon emissions and the earth's diminishing raw resources associated with fossil fuelled power generation and widespread dumping practices. As a first step the surest way to challenge the present monopoly of the fossil fuel industry is to exploit the full potential of photosynthesising processes, whereby carbon remains the key chemical element for fulfilling the needs of contemporary and future civilisations and whereby the means will be available to control the concentration of green house gases at optimal levels in the environment. Envisaged are global recycling trading schemes based on captive carbon processes and systems for the conversion of existing fossil fuelled power stations to cyclic global power generation using photosynthesised fuel, whereby emitted carbon gases are recycled to sites of photosynthesis for further fuel production thereby creating closed cyclic trading systems with the possibility of completely eliminating global greenhouse gas emissions into the environment from power generation. The further innovations of the present disclosure consist of alternatives to fossilised carbon for transport based on global cyclic photosynthesising systems as well as the production of potable water and a host of carbon based commodities such as furnishings, textiles, pharmaceuticals, chemicals and food production to achieve maximum mitigation of environmental pollution combined with economically viable carbon-based processes.

The invention provides methods and compositions for reducing the malodorous sulfide gas released by a wastewater treatment system. The method preserves the vitality of waste consuming organisms within the system. The method comprises the steps of: determining the SRP PAA demand of the system, determining the aerobic PAA demand of the system, and adding a composition in an amount such that it is in excess of the SRP PAA demand but is below the aerobic PAA demand. Even though the composition increases the amount of sulfates within the wastewater it reduces the amount of SRP which prevents the malodorous sulfite gas release. The composition comprises at least one percarboxyacid. 1. A method of reducing the odor released by a wastewater treatment system without eliminating the entire aerobic and/or anaerobic bacteria population within the system , the method comprising the steps of:continuously or variably adding to a process flow of water a composition in an amount such that it is in excess of the SRP PAA demand but is below the aerobic PAA demand,detecting an increase in PAA demand in the process flow of water,in response to the detected increase in PAA demand, adding an effective amount of PAA to the flow to reduce the PAA demand to levels which are found to reduce malodor,wherein the composition comprises at least one peroxy acid.2.
