3. Specifications and Performance of "TMR090 Series" Module
Table III-3 shows the specifications of "TMR090 Series" modules.
EPDM is equipped as standard membrane material for the diffuser. EPDM has been used in
a lot of application for sewage treatment and industrial wastewater treatment and wears well.
However, EPDM is weak to oil and solvent. For wastewater containing high concentration of
oil and solvent, polyurethane is the preferable choice. We have the line-up of polyurethane
membrane diffuser-equipped TMR090 as an option. Please contact us if you have any
difficulties in choosing the type of diffuser.
