Part 2 — What is a Double Membrane Gas Holder?

It’s a breathing gas cover that safely stores the biogas produced by anaerobic digestion.

Three components

· Outer membrane — wind/rain/UV shield; continuously holds positive pressure on the inner membrane, keeping hydrostatic balance

· Inner membrane — directly contacts biogas; expands & contracts with gas volume

· Bottom membrane — separates the foundation from inner & outer membranes; leak-proof, corrosion-resistant

Why breweries depend on it

Pain Point → Solution

Pain PointHow the Double Membrane Solves It
Volatile biogas productionAdjustable volume — auto expands/contracts with output
Coastal salt spraySpecialized biogas membrane — salt-spray, UV, methane-permeation resistant
Typhoons / heavy stormsOuter membrane holds pressure — no deformation, no collapse
Limited footprint3/4 spherical shape — saves 60%+ land vs steel tanks
Long on-site constructionFactory-prefab + bolted on site — <50% of steel-tank installation time
High maintenance costSelf-cleaning, anti-aging, anti-oxidation — virtually zero maintenance

Part 3 — On-site at 100 m³: “HAIYUE-level detail”

This Sanya project — from delivery to commissioning — passed every test in one run.

Before delivery

· Membrane thickness, bolt specs, and anchoring system tailor-reinforced for Sanya’s specific salt-spray class, UV index, and wind load. Not a one-size-fits-all shipment.

During installation (senior site engineer on site)

· Anchoring system positioning accuracy: ±2 mm

· Positive/negative pressure water seal test: 100% leak-free

· Every bolt’s torque: logged individually, double-checked

· Control cabinet: dual-redundant signals (gas-holder pressure + inner membrane volume)

During commissioning (safety protection calibration)

· Prevents inner/outer membrane over-pressure

· Auto pressure-relief on abnormality

· Auto pressure-adjustment on gas-output fluctuation

At handover

· Complete installation log

· Commissioning report + effluent data

· Equipment operation training

· Lifetime remote support channel

“We don’t deliver a piece of equipment. We deliver 30 years of peace of mind.”
