Local and Eu regulations are complicating the disposal of sewage sludge, leading to a sharp increase in disposal costs. SewaTOR through controlled cavitation effectively breaks up the sludge’s particles, by maximizing the yield of biological processes and reducing the volumes leaving the plant. In this way WWTP manufacturers can design more flexible, compact and competitive plants and WWTP managers can optimize the energy efficiency and the yield of the plant, by saving money from the management costs!
