Energy Recovery
Although wastewater treatment requires a lot of energy, it is a major source of clean energy. For instance, some treatment phases release methane, which can be captured and recycled to produce heat and electricity. On the other hand, treatment sludge can make for an excellent source of fertiliser. By harnessing these different clean energy sources, EPAS International can turn a necessary process into a source of energy.
