The present invention is a pulse spilling self-aerator (PSSA) that has the potential to greatly lower the installation, operation, and maintenance cost associated with aerating and mixing aqueous solutions. Currently, large quantities of low-pressure air are required in aeration systems to support many...http://www.google.es/patents/US6395175?utm_source=gb-gplus-sharePatente US6395175 - Method and apparatus for energy efficient self-aeration in chemical, biochemical, and wastewater treatment processes
