Product Description
Tubular Microporous Aerator is a mature, reliable, and energy-efficient aeration device specially designed for municipal and industrial wastewater biochemical treatment. The core components include a high-performance silicone/EPDM rubber membrane and a hollow water-filled support body, delivering industry-leading oxygen utilization rate, uniform bubble diffusion, and excellent anti-backflow performance. This energy efficient tubular aerator is the core equipment of the activated sludge process, which can effectively reduce aeration energy consumption and improve biochemical treatment efficiency, helping users meet strict effluent discharge standards with lower operating costs.
Our EPDM membrane tube aerator adopts zigzag long aeration holes, which can release micro-bubbles with a diameter of less than 2mm during aeration, achieving an oxygen utilization rate of 28-35% with small pressure loss. For users, this reduces aeration energy consumption by 30-40% compared with traditional aeration equipment, greatly cutting monthly electricity bills and long-term operating costs, while improving the degradation efficiency of organic pollutants in wastewater.
The aeration membrane is made of high-quality EPDM rubber and silicone, with excellent heat resistance, ozone resistance, acid and alkali resistance, and chemical stability. Compared with ordinary rubber membranes, it has stronger anti-aging performance and longer service life, which reduces the frequency of membrane replacement, avoids unplanned shutdowns for maintenance, and lowers the total cost of ownership for users.
The built-in air guide groove ensures rapid and uniform gas distribution inside the aerator, making the membrane evenly stressed and the bubble diffusion more uniform. When air supply stops, the rubber membrane tightly fits the air guide groove, completely preventing sewage backflow. The hollow water-filled support body greatly reduces the buoyancy of the aerator in water, avoiding pipeline floating and damage, and ensuring long-term stable operation of the aeration system.

Pipeline Layout & Inspection: Design and lay the aeration main pipe and branch pipe according to the project drawing, check the pipeline for damage and blockage, and ensure the pipeline levelness.
Mounting Bracket Fixing: Install and fix the aerator mounting bracket on the tank bottom according to the design spacing, ensuring firm fixation and consistent elevation.
Aerator Connection & Sealing: Connect the tubular microporous aerator to the branch pipe, tighten the sealing parts to avoid air leakage, and ensure the aerator is installed horizontally.
Air Tightness Test: Conduct an air tightness test before water filling, check for air leakage at the connection parts, and adjust and repair in time.
Trial Operation & Calibration: Fill the tank with water to submerge the aerator, start the fan for trial operation, check the aeration uniformity, and calibrate the air supply volume.
Municipal Sewage Treatment: Urban sewage treatment plants, municipal reclaimed water reuse projects, sludge aerobic digestion projects
Industrial Wastewater Treatment: Chemical plant sewage, pharmaceutical wastewater, food & beverage wastewater, livestock breeding wastewater treatment
Biochemical Treatment Systems: Activated sludge aeration tanks, oxidation ditches, SBR reactors, contact oxidation tanks, and aerobic biological treatment projects
