摘要： A novel biologically active water treatment system for removing contaminant from industrial effluent and method thereof is provided. A novel upflow bioreactor system having an expanded bed configuration and method for creating an expanded bed for release of gas without release of substantial precipitate is also provided. A novel downflow bioreactor system having an automated degas and backwash system is also provided.

摘要： A biological reactor system treats concentrated contaminated water with a combination of upflow and downflow bioreactors that are downstream from a reverse osmosis or other concentrator. The system may have a fail safe configuration where flush water may be introduced to the reactors in the event of a power failure or when taking the reactors offline. Many reverse osmosis systems introduce antiscalant treatments upstream so that the reverse osmosis filters do not scale. However, such treatments result in superconcentrated conditions of the antiscalants in the contaminated water processed by the bioreactors. A flushing system may deconcentrate the bioreactors to prevent the antiscalants from precipitating and fouling the bioreactors.
