A system that uses thermal addition, particle size reduction, increasing surface area, pressure reduction and kinetic energy increases to vaporize and dewater wastewater and/or sludge and/or other liquids mixed with entrained solids to produce a cleaned water condensate and a dewatered solid product. The wastewater and/or sludge enters a cylindrical drum through a rotary entrance valve. A rotating hammermill inside a drum with an exterior thermal jacket pulverizes the entering wastewater or sludge with rotating blades that keep the pulverized product against the inside of the drum's inside surface to vaporize water to separate it from solids. The vaporized water is condensed and discharged from the system and a solid product exits the drum via rotary valves. A vacuum is maintained on the drum to enhance the system.

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.
