Title: Innovations in Wastewater Treatment by Bruce R Johnson
Introduction
Bruce R Johnson is a notable inventor based in Boise, ID (US), recognized for his contributions to wastewater treatment technologies. With a total of seven patents to his name, Johnson has made significant strides in developing methods that enhance the efficiency and effectiveness of wastewater management systems.
Latest Patents
Among his latest patents, Johnson has developed a wastewater treatment system that describes innovative methods for treating wastewater. In one exemplary method, wastewater is divided into first and second fractions. The first fraction is directed to a membrane bioreactor, which produces an effluent with a low pollutant concentration. The second fraction is sent to a biological wastewater treatment system, which may yield a higher pollution concentration but operates with a shorter solids retention time. This invention can routinely meet or exceed pollution discharge standards economically during normal operations while maintaining flexibility to handle seasonal or sudden variations in wastewater flow. Additionally, waste activated sludge containing heterotrophs, autotrophs, and optionally polyphosphate accumulating organisms is transferred from the membrane bioreactor to the biological treatment system.
Career Highlights
Throughout his career, Johnson has worked with prominent companies such as CH2M Hill, Inc. and Hewlett-Packard Company. His experience in these organizations has contributed to his expertise in the field of wastewater treatment and environmental engineering.
