摘要: An activated carbon adsorption column for the treatment of waste water is continuously sterilized and/or regenerated in pulsed batches of carbon amounting to 5 to 25 percent of the working column quantity transferred, alternately, from the influent face of the column to one of two, off-stream blow case vessels for steam processing and returned to the effluent face of the working column upon the next programmed pulsing interim.

摘要: Water is treated to selectively remove substantially all of the nitrates present. This selective removal of nitrates is accomplished by adjusting the pH of the water to be treated, if necessary, to a pH of less than 8, and then passing the pH-controlled water through activated carbon. In one of the preferred embodiments, the spent activated carbon is substantially completely regenerated by backwashing to permit reuse of the carbon.
