CHP for wastewater treatment plants
smartblock® CHP for wastewater treatment plants (WWTP)
The use of a CHP unit in wastewater treatment plants allows optimum energy utilization of the resulting sewage gas. Especially on small municipal wastewater treatment plants, the energy efficiency of a CHP unit is superior to feeding gas into the natural gas network (see also VSA info sheet: Utilization of sewage gas - CHP or feeding?). Our CHP units offer an optimal solution for operation as a combined heat and power (CHP) plant. Thanks to standardized series production, the smartblock units are characterized by very low prime and operating costs. The control options offer various possibilities for the integration of the CHP unit. A complex and expensive superordinate control system can thus be avoided.
With smartblock 16 to smartblock 75, KW Energie's smartblock series forms a product range in the power segment up to 75kW electric, staggered according to demand. This corresponds to a sewage gas production of 100 - 700m3 per day.
smartblock® s series as an emergency power system
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 wastewater treatment plants require gas treatment in order to avoid unnecessary damage caused by sulfur and siloxanes and thus increased maintenance effort on the gas engines and apparatus. For this purpose, 42technology offers ready-to-connect gas purification modules matched 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, a gas heating system. The dry gas is then filtered by means of activated carbon.
A control that can do a lot
The smartblock control is equipped with additional functions that allow to control and monitor entire plants. The following additional functions are optionally available:
