Diffusers
HMT diffusers are engineered to provide efficient and uniform aeration in wastewater treatment systems, maintaining optimal dissolved oxygen levels for biological processes. Available in fine and coarse bubble configurations, they deliver high oxygen transfer efficiency across treatment tanks.
Durable, corrosion-resistant materials ensure long operational life even in aggressive wastewater environments. Uniform air distribution improves treatment efficiency while reducing energy consumption and maintenance requirements.
HMT diffusers are used in STPs, ETPs, MBBR, SBR, and MBR systems, including aeration and equalization tanks. When combined with HMT membrane technologies, they optimize biological performance and overall plant efficiency.

Premium Fine Bubble & Coarse Bubble Diffuser Solutions by Hollowbrane
At Hollowbrane Membrane Technologies (HMT), we redefine aeration efficiency. Our advanced diffusers are the heart of biological treatment processes (ASP, MBBR, MBR, and SBR), designed to provide uniform air distribution, high oxygen mass transfer, and long-term clogging resistance.
PRODUCT CATEGORY SECTION
Our Aeration Portfolio
We offer a complete range of diffusers tailored to different tank geometries and wastewater characteristics:
- Fine Bubble Disc Diffusers
- Best For: High-efficiency oxygenation in domestic and industrial STPs.
- Key Advantage: Produces bubbles between 1–3 mm, maximizing the surface area for oxygen transfer.
- Membranes: Available in high-grade EPDM or Silicone.
- Fine Bubble Tube Diffusers
- Best For: Large-scale aeration tanks and high-density floor coverage.
- Key Advantage: Higher floor area coverage and easy installation on lateral pipes.
- Coarse Bubble Diffusers
- Best For: Grit chambers, equalization tanks, and aerobic digesters where mixing is more critical than oxygen transfer.
- Key Advantage: Non-clogging design with very low back pressure.
