Recycled waste water is treated to remove contaminants and produce a sludge cake with a high percentage of solids and to produce a treated recycled waste water that can be discharged into a municipal sewer system. An exemplary system includes multiple domains each having a particular type of wireless device management system and respective APIs. The duration and magnitude of the torque pulse are subtracted from a torque signal and the resulting difference is integrated over time to obtain a fastener angular velocity signal.
