The objective of every sewage treatment plant is eliminating as much of the contamination in the wastewater as possible with the lowest effort possible. And those are precisely the strengths of electrokinetic disintegration with BioCrack. Treating the sludge breaks down aggregates and colloids. As a result, the micro-organisms can access the nutrients easier, more of the contamination is degraded. If the sludge is stabilized anaerobically in digestion towers, this can increase the gas or electricity yield by up to 15 percent. The costs for third party energy purchases are reduced, as are floating and sinking layer volumes. At the same time, the sludge viscosity is lower after treatment, decreasing the power consumption of pumps and mixers. Wastewater treatment in sewage treatment plants without sludge digestion can also be optimized with electrokinetic disintegration: The sludge treatment breaks down EPS structures, allowing better drainage of the sludge. This reduces the costs for sewage sludge disposal and flocculent requirements. In addition, the reduced viscosity decreases the energy requirements for ventilation. The system ensures stable process workflows and is generally easy to integrate and retrofit in the existing workflow, e.g. in the digester tower circulation line or the digester tower feeder. If no digester is installed, the return sludge can be treated before it is fed to the activation phase.
