USS - Waste Water Cleaning through Ultrasonic Resonance
To avoid releasing wastewater straight into the environment, complex and technical systems of water treatment have been developed, but these often produce themselves waste and use significant amounts of energy. The project successfully developed and tested an innovative Ultrasonic Plasma Resonator (UPR) in three applications. The process reduced chemical oxygen demand (COD) and total organic carbon (TOC) in the leakage water of a waste dump by 50%. In the pre-treatment of wastewater, it reduced ammonia by 50% with 50-70% less strip air consumption. In disinfecting communal wastewater it was able to achieve a decrease of bacteria from factor 100 (log 2) to 1000 (log 3). Further advantages are the complete elimination from the microbiological load of elements such as fungi and bacteria, and a drastic reduction of the nitrogen load. Other advantages include: quicker processing time, reduced space requirements, the absence of need for additional pumps or expensive expendables, and inexpensive initial outlay and operating costs.
