Product Catalog

Ecomembrane s.r.I (Italy) have been developing the application of plastic membranes for use in various industries for more than 20 years. Large production facilities equipped with ‘state of the art’ automatic machinery now manufacture membrane products, which have been specifically developed to provide cost effective and environmentally friendly solutions for biogas collection and utilisation. Membrane Gas Holders Replacement of existing steel Gas Bells Fitted directly to the top of Anaerobic Digester tanks Low pressure floating systems for tanks and lagoons Gas holders 1 – Air Chamber 2 – Biogas Chamber 3 – Air Blower Unit 4 – Air Inlet 5 – Anchoring System 6 – Level Sensor (4-20mA) 7 – Pressure Regulating Valve 8 – Condensate Drain 9 – Gas Inlet/Outlet Pipe 10 - Gas Safety Relief Valve Volume Capacity: From 10 to 5000 m3 with pressures ranging from 20 – 50mbar depending on the size. Safety: The patented 2 chamber and 3 overlapping membrane system completely divides the biogas from the air avoiding any potential explosive atmospheres. Raw materials: Are carefully selected and tested in-house before being used in order to warrant the product for a long working life without problems. Low energy usage: The air blower only runs when gas is being discharged from the gasholder requiring a fractional kW motor to maintain system pressure. Half sphere shape: Provides for constant and repeatable movements of the gas bag and consistency of level transmitters for control. Civil requirements: Simple flat concrete bases with cast-in anchor brackets. Above ground gas inlet / outlet pipework can be facilitated. Easy to operate: The gasholder is fully automated and requires minimal visual maintenance. Power Failure: The 2 membrane design enables the outer Membrane to remain inflated at all times. Cost: The capital cost to provide and install a membrane gasholder provides a considerable saving over conventional designs.

The constant pressure membrane gas holders can be specifically designed to fit directly over anaerobic sludge digester tanks of any shape or size. Floating gas storage systems are designed to collect and store low pressure (1-3 mbar). The covers can be made to suit round or rectangular tanks of any size.
