Comparison of MBR and Enzotech FRP

Defining Parameters MBR Enzotech - FRP Type

Sludge handling system requirement

 Sludge production is more. It needs Belt press or centrifugal sludge removal equipment.

Sludge removed by gravity on sludge bed

Advantages

Membrane process with extra pure outlet water quality for special use, smaller area requirement.

Classical treatment improved for higher efficiency to give better treated water for reuse, less space and less power requirement.

Disadvantage

Continuous maintenance of high MLSS, high membrane replacement cost, huge power requirement, highly trained operator required.

Chemical cost, mechanical maintenance are high
