Innovative Design of an Integrated Membrane System to treat Brewery Wastewater for Reuse using Computational Fluid Dynamics (CFD) and Energy Recovery Devices (ERD)

摘要

One of the largest breweries in the world invested on a water reuse system to reduce its current water ratio. This paper discusses the design of Tertiary Treatment system which was executed and installed adjacent to the existing industrial wastewater treatment plant in the brewery. The designed system involved a single process train including a pre-filter, a pressurized hollow fiber membrane Ultrafiltration and a Reverse Osmosis systems. UF system design incorporated Computational Fluid Dynamics (CFD) tools to analyze pipe sizing and fluid behavior and also the structural properties of the support frame holding the UF modules. The RO features an Energy Recovery Device (ERD) with a view not only to reduce energy consumption, but also to better balance the flux in the two-stage array system to improve performance and extend RO membrane useful life. Selected design features used to fulfil End-user goals and ensure overall system designed will be discussed.
