Advanced Aeration for
Clean Wastewater
LiTENDA supplies complete fine-bubble aeration solutions — disc diffusers, tube diffusers, and full system packages — designed for maximum oxygen transfer efficiency in industrial and municipal wastewater treatment.
What is an
Aeration System?
An aeration system is a device or system used to increase dissolved oxygen content in water. Widely applied in wastewater treatment, drinking water treatment, and aquaculture, it works by introducing fine air bubbles into water — promoting the growth and metabolism of microorganisms and accelerating the breakdown of organic matter.
LiTENDA's aeration systems combine fine-bubble disc diffusers, tube diffusers, and air distribution manifolds, all engineered to deliver consistent oxygen transfer efficiency with minimal energy consumption and long service life.
Whether you need equipment for a new plant or are upgrading an existing system, LiTENDA offers free technical consultation, custom design, and full after-sales support — talk to our engineers before you buy.

Four Membrane Types for
Every Wastewater
LiTENDA offers four distinct membrane materials — each selected for specific wastewater compositions, temperatures, and treatment challenges.
EPDM vs. PTFE Membrane Properties
Choosing the right membrane material directly impacts system longevity and operating costs. Here's how our two primary options compare.
| Material Property | EPDM Membrane | PTFE Membrane |
|---|---|---|
| Tensile Strength (psi) | 2,000 | 2,000 |
| Tear Strength (lb/in) | 110 | 110 |
| Change in Tensile Strength | < 3% | < 3% |
| Change in Elongation | < 25% | < 25% |
| Ozone Resistance (70h, 40°C) | Pass | Pass |
| Chemical Resistance | Good | Excellent |
| Resistance to Fats, Oils & Greases | No | Excellent |
| Solvent Resistance | Good | Excellent |
| Resistance to Aging | Good | Excellent |
| Fouling Resistance (Biofouling / Scaling) | Good | Excellent |
| Resistance to High-Hardness Wastewater | Good | Excellent |
Tube Diffuser Specifications
Our tube diffusers deliver reliable, energy-efficient aeration with small pressure loss and uniform bubble distribution — designed for long-term operation in demanding environments.
