AGROTEL GmbH has introduced SaniTarp®, a patented membrane designed to safeguard biogas tanks against corrosion from aggressive gases like hydrogen sulphide. This retrofit solution enhances the service life of fermenters, secondary digesters, and digestate storage tanks while minimizing downtime and improving the economic efficiency of biogas plants.

The membrane addresses infrastructure issues by allowing operators to refurbish existing tanks and quickly resume operations without extended shutdowns. SaniTarp® features a gas-tight, chemically resistant polypropylene coating on a durable fabric backing, ensuring protection for tank walls and supporting structures.

The installation process is quick and can be performed in various weather conditions. AGROTEL custom-manufactures SaniTarp® to ensure an optimal fit for complex tank geometries throughout their operational life.
