A process and apparatus to promote rupturing and destruction of biological cell walls for solubilization of biological sludge is provided. The process involves concentrating a sludge above an initial concentration by an evaporation process at the saturation temperature for the operating pressure, and a high shearing process applied to the concentrated solids. The invention also provides an apparatus to promote rupturing of biological cell walls for the destruction and solubilization of biological sludge, the apparatus with an evaporation region for concentrating sludge, a shearing region for rupturing the biological cell walls, and a sump region for receiving a feed stream of sludge and discharging a dewatered product stream. The process also provides a retention time for the destruction and solubilization to take place and providesfor the separation of water from the sludge for re-use.
