Title: The Innovative Contributions of Bengt G Hansson
Introduction
Bengt G Hansson is a notable inventor based in Hörby, Sweden. He has made significant contributions to the field of wastewater treatment, holding 2 patents that address critical environmental challenges. His work focuses on improving methods for treating peroxide-containing wastewater, which is essential for sustainable industrial practices.
Latest Patents
Hansson's latest patents include a "Method of treating peroxide-containing wastewater" and a "Method of controlling an anaerobic treatment process." The first patent addresses the difficulties associated with anaerobic treatment of peroxide-containing wastewater. The invention proposes a solution by reducing the peroxide content of the water through a catalytic pretreatment step, preferably an enzymatic pretreatment step. The second patent relates to treating wastewater from the manufacture of peroxide bleached mechanical or chemi-mechanical pulp. This method involves a hydrolysis step, methane fermentation steps, and an aerobic step. After these processes, sludge is separated from the wastewater and partially recycled to the hydrolysis step. The redox potential of the outgoing water from the hydrolysis step is continuously measured and controlled to a value between -400 and -260 mV by regulating the amount of sludge recycled or by directing incoming wastewater directly to the aerobic treatment step.
