In order to control the pressure inside the gas chamber, Ecomembrane manufactures and supplies a hydraulic safety valve. Constructed of stainless steel, the exhaust valve incorporates a self-priming tank partially filled with water that helps maintain the correct level inside the valve.
The biogas inlet pipe is installed through the top of the tank and terminates at a specific point in the exhaust valve’s self-priming tank, just below the water level that determines the desired overpressure level. In the event of overpressure, the biogas exhaust is evacuated through a vertical exhaust pipe thereby avoiding potential human contact.
