How It Works
Sufficient transmembrane pressure created by gravity drives the flow through the membranes. Clean water discharges into a clearwell while blocked solids remain suspended in the aeration zone. Diffusers beneath the module scour the membranes while also providing air supply to the bacteria.
TITAN MBR™ Flat-Plate Membranes—rated at the microfiltration level—maintain high permeability and flux rates even at peak-day rates.They stack within a fully submerged module inside the aeration zone. Chemical cleaning occurs efficiently inplace— typically on a semi-annual basis*—with simple chemical injection.

Advantages

Provides Long-Term Durability
Composed of PVDF [polyvinylidene fluoride] and a nonwoven polyester fabric, the vertical membrane surfaces do not touch each other during operation. A robust design prevents breakage experienced in other designs and produces higher flux rates over time.

Effectively Combats Problem Constituents
TITAN MBR membranes eliminate clogging problems experienced in hollow fiber designs. The Flat-Plate design with its smooth, continuous surface prevents the buildup of solids that result from hollow fibers being bundled by stringy solids—like hair.

Offers More Economical Cleaning Methods
TITAN MBR membranes utilize less chemicals and equipment than other designs. No backpulsing is required, which eliminates associated pumping equipment. TITAN MBR membranes facilitate air scouring in the aeration zone much more effectively than hollow fiber designs by the simple fact of their flat surfaces.
