Sewage treatment changed to a power plant

Sewage flowing from thousands of households, until now, has only been purified, turning them into drinking water. The US company DC Water has decided to use it in yet another way and launched a completely new Blue Plains complex, which, in addition to sewage treatment, also produces electricity.

The complex was built in the District of Columbia and, as it is owned by its owner, sewage flowing from all over Washington, is used to generate electricity. Power generation capacity is estimated at 10 MW, which should be sufficient to supply about 8,000 households with a large profit.

The wastewater treatment plant utilizes a hydrolysis technique to process organic material into methane. This in turn is used to drive turbines that generate electricity. Its production takes place in large 24-meter silos, which each year can process almost 15 million liters of sewage. The by-product of this process are biological residues that can be used as organic fertilizer for agricultural production, so this is an added benefit of this idea.
