摘要： A method for tracking a pollution source in process water is presented. Firstly, variation curves of drain water drained from different rinsing tanks are respectively obtained, and a water quality concentration of the drain water drained to a buffer tank is detected, so as to output a water quality variation curve. Then, an analytical comparison is performed on each drain water amount variation curve and the water quality variation curve within a same time interval, so as to output an analytical result of each flow of drain water in a range exceeding a predetermined water quality standard. In this manner, the drain water that exceeds the predetermined water quality standard can be tracked in real-time according to the analytical result, thereby quickly improving the process for discharging the drain water.

摘要： Contaminated water stored in an equalization basin is distributed to one or more flash vessels and a desired vacuum is pulled in a filled flash vessel, reducing the boiling point of the contained contaminated water. The suction force is preferably created by passing the contaminated water under pressure through a differential pressure injector. The contaminated water in the flash vessel completes an electrical circuit between conductive plates and a heating element that are submerged therein. An alternating electrical current is applied, some of which is conducted by the contaminated water to a heating element that heats the water, and the rest of which dissipates as thermal energy, heating the contaminated water. The alternating current is preferably generated by passing the contaminated water under pressure through a hydroelectric power generator. Little thermal energy is needed to evaporate the contaminated water, which condenses at the top of the flash vessel and is collected from a collection trough. Slurry created by distillation is delivered to the equalization basin to increase the conductivity and temperature of the stored contaminated water.

摘要： A method for removing contaminants from an influent wastewater stream includes initially chemically adjusting a pH of the influent wastewater stream to less than about 3.5 or maintaining the pH of the influent stream at less than about 3.5. After initially adjusting or maintaining the pH of the influent wastewater stream, the wastewater is directed to a first reverse osmosis system and contaminants are removed from the wastewater. The wastewater is then directed to a second reverse osmosis where additional contaminants are removed from the wastewater. After the wastewater has been subjected to treatment in the first reverse osmosis system and prior to treatment in the second reverse osmosis system, the pH of the wastewater is adjusted upwardly.

摘要： The present invention provides a novel adsorbent carbon supported activated alumina (CSAA) which posses both the advantageous characteristics of carbon and alumina viz., the high specific surface area associated with activated carbon and high sorption capacity of alumina towards F− Carbon supported activated alumina has an added advantage of its usage in the neutral pH unlike alumina and alumina impregnated carbon which are found to be efficient only in acidic pH. It is more efficient compared to carbon in terms of its sorption capacity towards F− and is therefore useful for the efficient removal of fluoride ions from water.

摘要： Divalent and trivalent metal salts are added to the solution containing the fluorine compound to precipitate the layered double hydroxide containing the fluorine compound between layers. By these processes, the fluorine compound can be fixed with high rate. Moreover, if necessary, the precipitated layered double hydroxide can be recovered to separate the fluorine compound or its salt between layers. Therefore, the burden to environment or the ecosystem by the fluorine compound can be reduced.
