Details
Inside the fully enclosed air dome
This sludge fermentation air dome features fully sealed airtight construction. Slight positive internal pressure prevents leakage of ammonia, hydrogen sulfide and pathogenic microbes. Equipped with auxiliary deodorization systems, it guarantees compliant fugitive emission, eliminates secondary pollution and NIMBY concerns to meet strict environmental assessment requirements.
Its large-span pillar-free interior enables frequent access for turners and loaders. Compared with conventional concrete workshops, the air dome boasts shorter construction period, superior tightness, lower investment and maintenance cost, running steadily all year round as an eco-friendly solution for harmless and resource-oriented municipal sludge treatment.
Sludge fermentation inside the air dome
Equipped with IoT sensing technology, our sludge fermentation air dome monitor and automatically regulate internal temperature (55-65℃), oxygen concentration (10%-15%), and humidity in real time.This precise aerobic fermentation environment significantly shortens the composting cycle, efficiently eliminates pathogens and parasite eggs, and achieves rapid sludge reduction, harmlessness, and resource recovery.
Vehicle operations within the air dome
Manufactured with B1-grade flame-retardant PVDF composite membrane, this sludge fermentation air dome features high tensile strength and excellent weather resistance, with a design service life of over 25 years.The large-span, beamless, and column-free space (up to 100 meters) perfectly accommodates barrier-free operations of heavy-duty turning machinery. The self-cleaning and anti-aging membrane provides robust physical protection for long-term operation.

FAQ
Q1: How many people are needed to set up a 7,000 sqm air dome?
A1: Only 8-10 people are required. Since the air dome is prefabricated in the factory and simply transported to the site for installation and anchoring, the entire process can be completed in about 10 days.
Q2: Are the operation and maintenance (O&M) costs high?
A2: Not at all. The intelligent control system allows for unattended operation, and the membrane material features self-cleaning capabilities. Annual inspections are only needed to check for any wear and tear on the membrane and equipment. Overall, the O&M costs are lower than those of traditional buildings.
Q3: Can the air dome be expanded?
A3: Yes, it can. The air dome can be expanded later on based on your needs, making it highly flexible to adapt to various usage scenarios.
Q4: What is the lifespan and fire rating of the membrane material?
A4: The air dome utilizes Class B1 Fire Retardant PVDF Membrane. It features high tensile strength and excellent weather resistance, providing a service life of over 25 years with proper maintenance.
Q5: How does the air dome perform in extreme weather conditions?
A5: It is highly wind and snow resistant, capable of withstand Level 12 winds, and operates reliably in a wide temperature range of -40℃ to 60℃ to guarantee constant environmental conditions 24/7.
Q6: How does it prevent odor leakage during municipal sludge treatment?
A6: The fully sealed airtight construction maintains a slight positive internal pressure. This prevents the escape of ammonia, hydrogen sulfide, and pathogens. When combined with auxiliary deodorization systems, it ensures compliant fugitive emissions.
