Sewage gas
Cogeneration technologySewage gas-fired CHP units play an important role in the treatment and energy recovery of the waste sludge in the waste water treatment plants. The sewerage gas is a by-product of the anaerobic digestion of an organic sludge in these plants. CHP units convert this gas efficiently into the power and heat. In this way, the waste sludge becomes a useful source of energy, which increases the energy efficiency of the waste water treatment plants and reduces their operating costs. In addition, this also minimizes the greenhouse gas emissions.
