At wastewater treatment plants, increased priority must be given to emergency power in the future. Public networks are becoming more and more vulnerable with regard to short- or long-term network failures. Mains backup power ensures that sewage treatment plant operations are maintained, minimizing the risk of damage to the plant and the environment. The smartblock CHP has an emergency power function that, in combination with a customized design of the junction box, can supply power to the main consumers of the wastewater treatment plant. When the grid returns, the CHP automatically synchronizes back to the grid without interruption.
CHP units at sewage treatment plants require gas treatment in order to avoid unnecessary damage caused by sulphur and siloxanes and thus increased maintenance costs for the gas engines and apparatus. 42technology offers ready-to-connect gas purification modules tailored to the sewage gas volume and quality. The gas cleaning module usually consists of a gas cooling system for dehumidification, a gas pressure increase and, if necessary, gas heating. The dry gas is then filtered using activated carbon.
The gas cooling removes the moisture from the sewage gas by falling below the dew point temperature. Condensate in downstream gas lines is avoided and suspended matter is separated. The activated carbon filter removes pollutants from the process gas, thereby increasing operational safety. The gas treatment module is permanently technically tight and manufactured in compliance with SVGW. Installation in a container is also possible. The well thought-out design allows easy handling and maintenance.
The smartblock control is equipped with additional functions that allow to control and monitor entire plants. The following additional functions are optionally available:
