20080245732 | Methods of using waste waters produced by water purification processing - Water contaminated with sodium, calcium or magnesium salts or chloride, sulfate or carbonate salts is processed to produce a clean water stream and a waste water stream. The clean water stream is analyzed to determine if the sodium content is too high for potable use and, if so, the clean water stream is applied to soil to improve rain catchment for pond sealing. | 10-09-2008 |
20090057240 | Process for electrolytic production of chlorine products and byproducts - An integrated process separates salts from salty waters and electrolyzes the salts to produce chlorine products such as chlorine, hypochlorites, chlorates and/or caustic soda. | 03-05-2009 |
20090065201 | Methods of formulating drilling cements using processed waste waters - In oil or gas well drilling, saline water is collected and separated into first and second streams of solid or liquid products containing salts. The first products are used in formulating cements for fabricating drilled well casings. | 03-12-2009 |
20090065259 | Methods of formulating drilling muds using processed waste waters - In oil or gas well drilling, saline water is collected and separated into first and second streams of solid or liquid products containing salts. The first or second product is added to drilling fluids as a weighting agent. | 03-12-2009 |
20100050513 | Methods of growing aquatic flora - A method of growing rooted plants and non-rooted aquatic organisms in a pond. Rooted aquatic plants are planted spaced apart and non-rooted aquatic organisms, such as floating plants or algae, are grown in the space between the rooted plants. | 03-04-2010 |
20100051556 | Methods of purifiying water using waste brines to regenerate ion-exchange resins - Water is purified by ion-exchange. The ion-exchange resins are regenerated by contacting the resins with waste brines previously discarded, thus to improve the economics of discarding the waste brines and, in appropriate cases, providing for recovery of valuable by-products. | 03-04-2010 |
20100147767 | Method for purifying waste saline waters without reagent waste - Waste saline waters are purified by contacting with a cation exchange resin in hydrogen form, then with a WBA resin and, if desired, with a SBA resin. The cation exchange resin is regenerated with a strong acid reagent. The WBA resin is regenerated with ammonium hydroxide reagent. The SBA resin is regenerated with an alkali metal hydroxide. The residual reagent values in the spent regenerants are applied to the soil as amendments, fertilizer, for pH control, wind erosion control, deicing roadways and in Enhanced Oil Recovery. | 06-17-2010 |
20110255917 | METHODS FOR DEICING ROADS - Roadways are deiced or ice formation on roadways is prevented by applying salt compositions derived from waste water streams from water softening operations. | 10-20-2011 |
20110257052 | Method for Practicing Microbial Enhanced Oil Recovery Using Nitrogen Containing Fertilizers Recovered from Contaminated Water for Feeding Microbes - A method of using nitrates, nitrites, or ammonium recovered from contaminated water for feeding microbes used in microbial enhanced oil recovery (MEOR). If required, the nitrogen waste removed from contaminated waters is treated to be converted as nitrates or nitrites. The nitrates and nitrites are mixed with microbes that are then injected into oil wells for improved tertiary oil production or injected separately depending on balance of feed and microbes in well brine as judged from examining brine that exits well with the oil. The use of nitrates recovered from contaminated waters to feed microbes in MEOR is cost effective for both the process of water decontamination and oil recovery. | 10-20-2011 |
20120061315 | 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 - 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. | 03-15-2012 |
20120260707 | Using Nitrogen Containing Fertilizers Recovered from Contaminated Water for Feeding Plants and Algae - A method of using nitrates, nitrites, or ammonium recovered from contaminated water for feeding plants and algae. If required, the nitrogen waste removed from contaminated waters is treated to be converted as nitrates or nitrites to become readily absorbed by plants and algae. The use of nitrogen containing fertilizer recovered from contaminated waters to feed plants and algae is cost effective for both the process of water decontamination and the growth of plants and algae. | 10-18-2012 |
