The project

Digester gas production at a wastewater works never matches demand minute by minute. Welgedacht solved this with a 2,150 m³ Sattler double-membrane gas holder supplied and installed by Renew for WEC Projects.

The holder buffers production peaks, maintains constant delivery pressure to the gas users and keeps losses to a minimum with a permanently gas-tight inner membrane.
