Title: The Innovative Contributions of William M Copa
Introduction
William M Copa is a notable inventor based in Wausau, Wisconsin, recognized for his significant contributions to wastewater treatment technologies. With a total of seven patents to his name, Copa has developed innovative processes that enhance the purification of wastewater, addressing critical environmental challenges.
Latest Patents
Copa's latest patents include a two-stage anaerobic/aerobic treatment process and a two-stage batch wastewater treatment. The two-stage anaerobic/aerobic treatment process involves a biophysical anaerobic treatment to remove the majority of the chemical oxygen demand (COD), followed by a biophysical aerobic treatment for further purification. This process utilizes a powdered adsorbent, preferably activated carbon, in both treatment stages. Excess biophysical solids from the aerobic step are transferred to the anaerobic step for digestion, ensuring efficient treatment. The two-stage batch wastewater treatment process introduces a predetermined quantity of wastewater into an aeration and settling zone, where it is aerated in the presence of activated carbon and biologically active solids. After aeration, the treated wastewater is allowed to settle, and a portion is withdrawn for further agitation and treatment, ultimately resulting in clarified, solids-free water.
