<p>The systems may be used for treatment of water that contains contaminants. Water containing at least one of a nitrate, percholate, chromate, selenate and a volatile organic chemical(20) is combined with nutrients (22) and then is processed in an anoxic-anaerobic bioreactor (12). The combined effluent (30) may also be oxygenated by dosing with hydrogen peroxide (24) or liquid oxygen(32). The combined effluent of the bioreactor (30) is dosed with a particle conditioning agent (34). The combined effluent treated water of the bioreactor (30) is then filtered in a biofilter (14) to produce a treated effluent stream (38). The influent water and combined effluent of the anoxic-anaerobic bioreactor may also be dosed with hydrogen peroxide (24) to control biomass content in the system.</p> |
