Gas holder contains of 3 main parts: external membrane, bottom membrane and inner membrane. The external membrane is always sustaining a positive pressure to maintain the shape and protecting the system against i.e. storm or bad weather. The internal membrane is used for the effective storage of biogas, and it is always floating up and down according to the filling level of the biogas storage. The bottom membrane seals the storage upon the foundation to ensure gas tightness.
An overpressure protection device (hydraulic safety valve) is provided to prevent overpressure at emergency case. Antifreeze can be added to the water sealing for working during cold weather.
Stainless steel rails and Hilti Anchors are used for fast and efficient installation.

 

MEMBRANE

Biogas membrane is made of basic fabrics plus special PVC/PVDF coating with flame retardant, fungicide and UV- protection functions. 
The external membrane always requires a high strength and high self-cleaning function. The internal membrane and bottom membrane require very good biogas tightness, and remaining chemical-inert from the main components of the biogas i.e. H2S and CH4. The strength of the membranes range is between 4,000 N/5cm and 9,000 N/5cm, which can be chosen according to wind load and snow load calculation.
