NHPA050-1C

Submerged Flat-sheet Membrane Bioreactor (MBR)
for Biological Wastewater Treatment
The NHPA series incorporates thin membrane sheets for improved
flexibility, same as current NHP series, allowing more membrane area per
footprint.
In addition, the NHPA series has unique features that can be applied
to various situations such as water capacity, height and width since themodule configuration can be adjusted while maintaining the operationalfeatures of the current NHP series.
