Biogas systems are becoming an essential component of India’s renewable energy infrastructure, helping industries and communities convert organic waste into clean, usable energy. At the core of every efficient biogas plant lies a biogas membrane cover—a specialized PVC-coated fabric structure designed to store gas reliably and safely.

To ensure maximum gas yield, long-term durability, and safe operation, regular maintenance and inspection of biogas membrane covers is essential.

As one of India’s leading manufacturers of high-performance PVC-coated fabrics,LUCKY-TECH MEMBRANES, in exclusive partnership with Sioen Industries, Belgium, provides world-class biogas membrane materials engineered for longevity, chemical resistance, and maximum gas retention.

This guide will help plant owners understand the key maintenance practices required to extend the life and efficiency of their biogas membrane covers.

1. Routine Visual Inspection

Regular visual checks help detect early signs of membrane wear or mechanical damage.

Look for:

Surface cracks or discoloration
Tears, punctures, or abrasion marks
Irregular bulging or sagging
Damage from animals or external objects

Early detection prevents minor damage from turning into costly repairs.

2. Check for Gas Leakage or Pressure Drops

A biogas membrane cover must remain gas-tight to maximize plant efficiency.

Inspection Points:

Listen for minor air or gas leaks
Check pressure readings regularly
Inspect welded seams for openings
Monitor daily gas volumes for sudden drops

PVC membranes from LUCKY-TECH MEMBRANES are engineered with advanced gas-barrier coatings to maintain stable pressure and prevent methane loss.

3. Keep the Surface Clean

Dust, bird droppings, algae formation, and organic deposits can weaken the membrane over time.

Cleaning Tips:

Clean the dome surface every 3–4 months
Use soft cloths or sponges
Choose PH-neutral cleaning solutions
Avoid abrasive brushes or strong chemical cleaners

Regular cleaning ensures better UV protection, improved gas efficiency, and longer membrane life.

4. Inspect Welded Seams & Joints

The welded seams are one of the most sensitive components of a biogas membrane.

Check for:

Weakening or separation of welds
Excessive stretching
Hardening or brittleness
Moisture accumulation around joints

High-frequency weldable PVC fabrics from LUCKY-TECH MEMBRANES ensure strong and airtight seam strength.

5. Monitor Tensioning Systems

Proper tension is vital for the structural performance of biogas domes.

What to inspect:

Cable tension
Anchor point stability
Deformation under wind or rain
Sagging areas

Well-tensioned membranes prevent excessive stress and prolong lifespan.

6. Ensure Proper Drainage

Water accumulation on or around the membrane structure can lead to premature degradation.

Maintenance Checks:

Remove standing water immediately
Keep drainage paths clear
Ensure rainwater flows smoothly off the dome
Inspect gutters and channels

Efficient drainage prevents membrane stretching and damage.

7. Evaluate Chemical Resistance

Biogas contains harsh components such as:

Hydrogen sulfide (H₂S)
CO₂
Moisture
Organic acids

PVC-coated membrane covers from LUCKY-TECH MEMBRANES are designed with chemical-resistant coatings to withstand these harsh environments.

Routine Checks:

Look for signs of corrosion
Inspect areas in direct contact with moisture
Ensure proper ventilation in double-membrane systems

8. Yearly Professional Inspection

In addition to regular checks by plant operators, an annual expert inspection is highly recommended.

Professionals can evaluate:

Membrane structural health
Tensioning system
Gas-tightness performance
Anchoring and support systems
Weld quality and coating condition

This ensures the biogas plant continues to operate safely and efficiently.

Why Proper Maintenance Matters

A well-maintained biogas membrane cover ensures:

✔ Maximum gas storage capacity
✔ Consistent methane production
✔ Long service life of 10–12+ years
✔ Reduced operational costs
✔ Improved plant safety
