Extracting energy from non-potable water of a sewer process

摘要

Extracting energy from clean, non-potable water that had been treated at a sewage station. The extraction is by driving a water turbine and electric generator with the non-potable water, oxidizing the water as it leaves the at least one water turbine and pressurizing the oxidized, cleaned, non-potable water and mixing it with a fresh supply of clean, non-potable water to feed into the at least one water turbine. The fresh supply may be open to atmosphere and at an elevation higher than that of the at least one turbine.
