Heating Sludge | Wastewater Anaerobic Digestion (Mesophilic)

Steam is dispersed uniformly at high velocities into the sludge which provides heat transfer instantaneously in a single pass. As the steam energy is transferred instantaneously, precise temperature control to +/- 1 °F can be maintained. As steam is injected directly, there is no thermal barrier for burn-on or build to cause plugging and fouling.
