Title: Soren Johannes Hojsgaard: Innovator in Wastewater Treatment Technologies

Introduction

Soren Johannes Hojsgaard is a notable inventor based in Hillerod, Denmark. He has made significant contributions to the field of wastewater treatment, holding a total of seven patents. His innovative approaches focus on improving the efficiency and effectiveness of sludge treatment processes.

Latest Patents

Among his latest patents is a system and method for treating wastewater and resulting primary and biological sludge. This method involves treating primary sludge and activated sludge produced by a wastewater system. A portion of the activated sludge is wasted to form biological sludge, which is then thermally hydrolyzed. The process includes cooling the thermally hydrolyzed biological sludge by mixing it with primary sludge. The combined sludge is subsequently directed through a pasteurization process and then to an anaerobic digester for anaerobic digestion.

Another significant patent is for an energy-efficient system and process for hydrolyzing sludge. This process relates to thermally hydrolyzing sludge in a thermal hydrolysis system. A flash tank or waste heat boiler is positioned downstream of the thermal hydrolysis system. Hydrolyzed sludge is continuously directed into the flash tank or waste heat boiler to recover supplemental steam. This supplemental steam can be used independently or in combination with live steam produced by a main boiler to heat sludge being directed into the thermal hydrolysis system.
