Biogas Project--waste water treatment

Two sets of 100 m³ double membrane gas tank sewage treatment project address: Yiwu City, Zhejiang Province

The double membrane gas holder is a durable air-supported structure designed specifically for the storage of biogas.Typically, gas holders are installed as part of anaerobic digestion systems in wastewater treatment plants , agricultural digestion projects , landfill sites , and cogeneration plants that utilize biogas generated from organic materials as an energy source.

The double membrane gas holder is primarily composed of three components: the outer membrane , inner membrane , and base membrane . The outer membrane serves a protective role for the system . Even under extreme conditions such as storms , the outer membrane continuously withstands positive pressure to maintain hydrostatic equilibrium . The inner membrane is used for storing biogas and expands or contracts based on the gas volume. The base membrane separates the foundation from the inner and outer membranes . Both the inner and outer membranes are made from specialized high quality biogas membrane material , possessing qualities such as UV resistance, aging resistance, abrasion resistance, methane permeation resistance, and a certain level of self-cleaning capability.
