Who are the individuals credited with developing the activated sludge process in Manchester, England, around 1914?
Answer
Edward Ardern and W.T. Lockett
Edward Ardern and W.T. Lockett were the researchers who observed that continuously aerating sewage sludge allowed microorganisms to multiply and rapidly purify incoming sewage. This discovery served as the foundation for modern biological wastewater treatment, allowing for the stabilization of organic matter within contained reactors rather than relying on slow, passive disposal methods.
