Brewery Reuses Water For Factory Wash-Down

Looking to reduce its water footprint, Shepherd Neame Brewery invested in a complete membrane bioreactor (MBR) wastewater recovery and re-use plant. Learn how the new plant's aeration system has helped to reduce the brewery's water-to-beer ratio to an industry-leading value of 3:1.

Use Of Pure Oxygen To Resolve Capacity And Odor Problems

The Escalon Industrial Waste Water Treatment Facility’s service area is seasonal and centered on tomato and pickle processing. The production season (roughly mid-July through mid-October) sees high hydraulic- and BOD loads that strain the facility’s capacity. During the high season highly variable BOD load depletes DO and causes permit violations and odor complaints. Praxair installed 4 X 15 HP Medium Velocity Oxygenation (MVO™ oxygenation system), with the ability to deliver up to 6 TPD of oxygen to supplement the existing aeration capacity at the facility.

QUA UF Membranes Provide Pretreatment for Seawater Reverse Osmosis (SWRO) System

How The Middle East Is Transforming Its Power And Water Industry

Global demand for power and water is accelerating — and the Middle East is no exception. A burgeoning population combined with multiple industrial diversification programs is fueling a boom in power and water projects. During the first three quarters of 2017, about US$30 billion of major power contracts and US$20 billion of water projects were awarded across the region. In 2018, the figure is looking more like $60 billion with the two sectors combined.
