Summary
Product Identification
The NHPA050 Series are submerged flat-sheet membrane bioreactor (MBR) products designed for biological wastewater treatment.
The NHPA series incorporates thin membrane sheets for improved flexibility, allowing more membrane area per footprint. The NHPA series also features adjustable module configurations to suit various situations regarding water capacity, height, and width, while maintaining operational features of the NHP series.
