NHPA150F

Summary

Product Identification

The NHPA150 Series is a Submerged Flat-sheet Membrane Bioreactor (MBR) designed for Biological Wastewater Treatment. This series incorporates thin membrane sheets for improved flexibility, allowing more membrane area per footprint. Its module configuration can be adjusted to suit various situations regarding water capacity, height, and width, while maintaining the operational features of the current NHP series.
