WATER REUSE SYSTEM AND METHOD

摘要

Disclosed herein are processes, methods, and devices for use in water reclamation, including a system comprising an osmotic membrane bioreactor (OMBR), a microporous membrane bioreactor (MBR), a biological nitrogen removal system (BNR), and a source of high osmotic pressure solution (draw solution), and a reconcentration process to achieve high water recovery at low energy expenditure, which may produce purified water streams of different qualities in parallel. Disclosed processes, methods, and systems for the treating of waste water may further provide for production other useful products, for example, fertilizers. One embodiment of the disclosed systems, processes, or methods may include a hybrid membrane bioreactor comprising a semipermeable membrane and a porous membrane.
