Latest Patents

Cobb's latest invention, titled "Sewage Sludge Treatment with Gas Injection," presents a groundbreaking system for treating sewage sludge. This system results in an oxygenated and/or ozonated treated sludge that contains substantially no pathogens. The process involves several steps, including mascerating raw sludge, adjusting the pH to about 2.5 to 3, and modifying the solids content to approximately 2.5% to 4%. Additionally, the temperature is adjusted, if necessary, to a range of 20°C to 40°C. The innovative aspect of this system lies in the mixing of an oxygen-rich gas, such as oxygen and/or ozone, with the sludge as it is recirculated through a hyperbaric vessel. This simultaneous injection of gas into a combination gas and sludge mixing assembly facilitates the atomization and oxygenation of the sludge, enhancing its treatment.
