Features and Benefits

•  Free membrane cover is designed for secondary digesters or anaerobic sludge storage tanks.  It provides the greatest volume of air chamber displacement for gas storage and sludge variation.
• Geodesic support dome is intended for either primary or secondary digesters with piping or other equipment  that could interfere with the travel of the inner membrane, which is permanently fixed at the top so that it cannot extend very far into the tank when the system is out of service and deflated.
• Separate gas storage units mount directly on a concrete foundation ring.  It is employed when only gas storage is desired and is substantially less costly than a high pressure gas storage sphere and does not require the use of compressors.
• High gas take off is designed for active primary digesters which have the potential for foaming.  The high location of the gas take-off makes it difficult for the foam to reach the gas piping.
