Abstract:

An apparatus for removing target chemicals from water includes a reaction chamber, a source of an aqueous solution of the target chemicals that can be supplied on demand to the reaction chamber, a timer that times a reaction between the particles and the target chemicals such that a concentration of the target chemicals in the aqueous solution reaches a predetermined low level in a desired time, and elements for removing the aqueous phase from the reactor while keeping the particles entrained inside the reactor using a microfilter configured to be back flushed, adding aqueous solution to the reactor from the source and continuing cycles until the particles are saturated, removing and replacing the particles in a final cycle of a particle charge lifetime, and recovering the target chemicals from the particles such that the particles can be reused.
