How Ecomembrane Boosts Biogas Efficiency

By Ecomembrane

In today’s competitive renewable energy market, every percentage point of efficiency matters. For biogas plant operators, that means investing in equipment that ensures precision, reliability, and long-term performance.

Ecomembrane—a global leader in biogas storage technology—has built its reputation on engineering solutions that do exactly that. Through innovation grounded in practical field experience, the company has developed two complementary technologies that set a new standard in biogas storage: the Air Valve and the Patented Volume Level Sensor. Together, they bring smarter control, safer operation, and greater output to every installation.

The Ecomembrane Air Valve: Intelligent Pressure Control Made Simple

The Air Valve is designed to deliver unmatched control over digester pressure and gas flow– wo key factors in maintaining a stable and efficient biogas system.

Its adjustable performance allows for operation between 3 and 40 mbar, allowing operators to fine-tune the working pressure of each digester, directing biogas from one to another with precision. Another key feature is the built-in fail-safe operation. Its mechanical servo command automatically seals the valve in case of a power outage, preserving internal pressure longer than conventional systems.

The direct connection design, using a special air flange that links directly to the air membrane, also removes the need for flexible plastic tubing that can cause pressure losses or be affected by weather damage.

Housed in a fully enclosed aluminum case, the system is protected from the elements—ensuring stable performance for the full lifespan of the cover, with no recalibration or maintenance required.

The Ecomembrane Patented Volume Level Sensor: Turning Precision into Productivity

Ecomembrane’s worldwide patented Volume Level Sensor takes gas measurement to the next level through mechanical precision and smart engineering. With unmatched accuracy, the stainless steel spring system physically connects the air and gas membranes, ensuring precise readings that remain unaffected by gas fluctuations.

Its traction-based design shapes the gas membrane to enable full use of the geometric storage volume – allowing operators to measure and utilize 100% of the available capacity, compared to the roughly 70% achievable with conventional systems.

Proven in more than 2,000 installations worldwide, the sensor consistently delivers reliable performance across a wide range of plant conditions. And thanks to its dual load-cell design with independent signal cables, maintenance is simplified—allowing quick, ground-level replacement that keeps downtime to a minimum.

Smarter Engineering for Sustainable Results

Ecomembrane’s technologies redefine what it means to build efficient, low-maintenance biogas plants. Both technologies embody a single philosophy: engineer with precision, design for longevity, and deliver measurable gains.

For developers and operators, that means safer systems, lower operational costs, and greater productivity—proof that true efficiency isn’t just about producing more energy, but doing it smarter, safer, and for the long run.

With Ecomembrane, efficiency isn’t a goal—it’s a guarantee.
