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

Номер: US20120061315A1
Автор: Gerald J Grott
Принадлежит: Individual

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.

Ion exchange regeneration and upw treatment system

Номер: US20120283343A1
Автор: Charles Dale, Charles Swenson, Robert J. Ritz, William D. McClain, William W. Carson
Принадлежит: General Electric Co

An improved process for regenerating ion exchange resin, includes a regeneration step of displacing captured ions from the resin to regenerate its ion-capture functionality, followed by one or more fluid-employing post-regeneration steps such as a fluid displacement or rinse, a fluid transporting or mixing, and a rinse down to quality. To avoid problems of early leakage of weakly held ions such as boron, the post-chemical or postdisplacement steps use water that is essentially free of boron, or otherwise avoid localized contamination in the regenerated resin which is used in bottles or beds ( 30 ). A two-stage polish may be operated with modified lead/lag bottles. A detector (D) for an indicator condition (conductivity, silica breakthrough) between stages determines when to shift the lag bottle forward, and periodically both bottles are replaced.

The softener is based on a capacitive-deionization (CDI) cell, in which the hardness ions are extracted, and disposed of still intact, in concentrated form. The softener is combined with a chelate to inhibit precipitation, in the appliance, from the concentrated effluent. The chelate being citric acid, the acidity is effective to keep the hardness ions in solution. The purify and regenerate modes of operation of the softener can be timed to coincide with the washing and rinsing cycles of the appliance, whereby the presence of the softener does not affect the speed and performance of the appliance.

Feed water is split into a first fluid stream, fed to a bypass conduit and a second fluid stream that is conveyed through a weak acid cation treatment bed. After passing through the bed, the treated fluid is combined with the bypass fluid stream to produce a blended feed water at the outlet. The ratio of the bypass fluid stream and treated fluid stream is a function of pH and L.S.I. A controller and associated sensors may control the relative flow rates between the bypass fluid stream and the treated stream to maintain a predetermined water parameter such pH, L.S.I., etc. within a predetermined range.

A continuous resin regeneration system includes a process by which resin in need of being recharged is continuously recharged and cleaned with a plurality of two-set filtration columns so that resin regeneration and the flow of influent is continuous and interrupted. Downstream filtration columns also undergo this cycling but at slower and related rates as the first column with the dirtiest water will naturally degrade resin faster than the downstream columns. Contaminated influent is cleaned by the continuously recharged resin in multiple column sets. The degree of cleaning of earlier filtration columns affects the resin flow rate of later filtration columns. 1. A continuous resin regeneration system for use in cleaning a water stream from a contaminated water reservoir , comprising:a first anion resin set having a first anion column and a second anion column in fluid communication with the first anion column, said first anion column and said second anion column of said first anion resin set including an anion resin;a first cation resin set having a first cation column and a second cation column in fluid communication with the first cation column, said first cation column and said second cation column of said first cation resin set including a cation resin;a first set control valve in fluid communication with the water reservoir, with said first anion column of said first anion resin set, and with said second anion column of said first anion resin set;a second set control valve in fluid communication with the water reservoir, said first cation column of said first cation resin set, and with said second cation column of said first cation resin set; anda controller in data communication with said first set control valve, said controller configured to determine if said anion resin associated with said first anion column of said first anion resin set is greater than a predetermined parameter and, if so, to actuate said first set control valve to direct the water stream ...
