TPU EPDM silicon membrane for making bubble tube diffusers with
different sizes for water treatment
Our membrane is used for making bubble tube diffusers.The device has small aeration bubble diameter, small gas-liquid
interface diameter, large gas-liquid interface area, uniform bubble
diffusion, no clogging of pores, and strong corrosion resistance.
It is especially suitable for urban sewage and large-scale factory
expansion and reconstruction of old aeration tanks, and the
aeration tanks can be operated intermittently.
Different material of membrane
1. EPDM (ethylene propylene diene monomer) rubber: suitable for
2. Low plasticity EPDM (ethylene propylene diene monomer) rubber:
suitable for industrial waste water from animal slaughter
processing, food processing, and beverage production
3. Silicone rubber: suitable for wastewater from pulp and paper
industry, petrochemical and refining processing, etc.
1.Use good quality raw material
The large surface area increases the aeration volume, improves the
oxygenation efficiency, and increases the service area.
3.Meticulous craftsmanship:Reasonable design, not easy to contain
dirt, easy to install.
