A mobile station and methods are disclosed for diagnosing and modeling site specific effluent treatment facility requirements to arrive at a treatment regimen and/or proposed commercial plant model idealized for the particular water/site requirements. The station includes a mobile platform having power intake, effluent intake and fluid outflow facilities and first and second suites of selectably actuatable effluent pre-treatment apparatus. An effluent polishing treatment array is housed at the station and includes at least one of nanofiltration, reverse osmosis and ion-exchange stages. A suite of selectively actuatable post-treatment apparatus is housed at the station. Controls are connected at the station for process control, monitoring and data accumulation. A plurality of improved water treatment technologies is also disclosed. The modeling methods include steps for analyzing raw effluent to be treated, providing a field of raw effluent condition entry values and a field of treated effluent condition goals entry values, and utilizing said fields to determine an initial treatment model including a selection of, and use parameters for, treatment technologies from the plurality of down-scaled treatment technologies at the facility, the model dynamically and continuously modifiable during treatment modeling.

Method and apparatus for producting negative and positive oxidative reductive potential (orp) water

ActiveUS20050121334A1Effective and efficient and economicalCellsWater treatment parameter controlParticulatesElectrolysis
A method and apparatus for electrolytically producing oxidation reduction potential water from aqueous salt solutions for use in disinfection, sterilization, decontamination, wound cleansing. The apparatus includes an electrolysis unit having a three-compartment cell (22) comprising a cathode chamber (18), an anode chamber (16), and a saline solution chamber (20) interposed between the anode and cathod chambers. Two communicating (24, 26) membranes separate the three chambers. The center chamber includes a fluid flow inlet (21a) and outlet (21b) and contains insulative material that ensures direct voltage potential does not travel through the chamber. A supply of water flows through the cathode and anode chambers at the respective sides of the saline chamber. Saline solution flows through the center chamber, either by circulating a pre-prepared aqueous solution containing ionic species, or, alternatively, by circulating pure water or an aqueous solution of, e.g., aqueous hydrogen chloride and ammonium hydroxide, over particulate insulative material coated with a solid electrolyte. Electrical current is provided to the communicating membranes separating the chambers, thus causing an electrolytic reaction that produces both oxidative (positive) and reductive (negative) ORP water.

Production of potable water and freshwater needs for human, animal and plants from hot and humid air

InactiveUS6868690B2Reduces cargo spaceMinimize any benefitGeneral water supply conservationSeawater treatmentParticulatesFresh water organism
Systems and methods are disclosed for extracting freshwater from atmospheric humidity in extremely hot and humid climates and supplying freshwater to a small group of people, a building, a farm, or forestation area. The freshwater is treated to provide drinking water by disinfecting to eliminate microorganisms and filtration to remove suspended particulates from air, erosion or corrosion products, and disinfected waste. Compact units provide drinking water for individuals, passengers in cars, vans, trucks, or recreational boats, or crewmembers on a seagoing cargo ship whether from atmospheric humidity or from moisture-laden gases. Furthermore, systems are disclosed for the ample supply of freshwater with minimal treatment for small- to large-sized buildings in a manner that alleviates the heat load on buildings. Collection of freshwater from hot humid ambient air is also provided for other uses, such as irrigation and farm animal drinking. Various methods are used for condensation of water vapor suspended in the air as alternative to conventional refrigeration cycles using CFC refrigerants. Devices are disclosed using naturally occurring brackish cold water, circulation of cooling water cooled by thermoelectric cooling or thermoacoustic refrigeration as well as evaporative cooling and transpiration cooling. Water produced by the systems may flow under gravitational forces entirely or with the assistance of boasting pumps.
