The Challenge
North central Mexico is home to one of the largest breweries in the world – which produces millions of liters of beer annually. As Mexico’s beverage industry developed, it became critical to produce energy-efficient water for brewing that didn’t interfere with the local water supply.
With rising water scarcity, recycling wastewater poses a viable solution for water conservation. In line with sustainability goals, the brewery implemented a coupled membrane wastewater treatment system with hollow fiber ultrafiltration as pretreatment and brackish water low-pressure reverse osmosis (RO). In wastewater reuse systems with multiple stages, membrane fouling resulting from imbalanced flux can be a barrier to optimal system operation. For this reason, the plant needed a solution to address fouling and increase energy efficiency.
