Water purification apparatus and method |
| abstract |
Disclosed herein is a method of treating an aqueous solution containing impurities including a perfluoroalkyl substance and/or a polyfluoroalkyl substance, comprising introducing the aqueous solution into a batch or semi-batch photocatalytic reactor with a microparticulate catalyst configured to reduce chain length of the perfluoroalkyl substance and/or polyfluoroalkyl substance, forming a treated aqueous stream, the reactor including a catalyst flow controller configured to automatically increase the catalyst concentration in the reactor while agitating the catalyst-containing solution during reaction, and removing catalyst particles from the treated aqueous stream to form a purified aqueous stream. In some cases, the feed to the reactor is atomized. Corresponding systems also are disclosed. |
