O₂ Automation: The Future of Bubble Mixing?

We have industrial accounts where we mix chemicals and acids. Our favorite is blending wine and spirits using compressed nitrogen. The old way to blend was to use “air rousing.” This was done by installing rows of perforated pipes in the bottom of the tank and attaching an air pipe to this grid. Since the typical mixing cycle was 45 minutes, copious amounts of air and energy were used.

Black & Veatch Provides Guidance to WWTP Design

Compressed Air Best Practices® Magazine interviewed Ms. Julie Gass P.E., Lead Process Mechanical Engineer, from Black & Veatch on trends in the wastewater treatment industry especially pertaining to new technology aeration blowers and energy efficiency.

Aerzen Delta Hybrid Blower - Designed for Wastewater Treatment Plant Load Profiles.

The concept offers new possibilities for generating positive pressure or vacuum in a variety of applications. “By applying screw compressor technology to low-pressure air compression, we’ve greatly improved efficiency,” said Pierre Noack, President and CEO of Aerzen USA. The Delta Hybrid has seven patents or patent applications, making it one of the most innovative products in compression technology.

Compressed Air in Wastewater Treatment

The object of this article is to look at some very typical industrial water treatment processes and various compressed air and energy savings projects that have worked well for our clients over the years. The basic fundamentals with regard to compressed air usage are similar to municipal water treatment – a good starting point.

Hoffman Revolution Blower Continues Tradition of Innovative Design

The Hoffman U.S. Machinery Division was established in 1905 outside of East Syracuse, New York. The initial product was an exhauster for the dry cleaning industry — pulling a steam vacuum across the garments. The Company grew and soon after began discovering industrial applications for their technologies. After the war period, during which Hoffman manufactured ball bearings and operated it’s own foundry, the company began discovering new industrial markets for it’s products. A significant part of their business was in the wastewater treatment industry.

Water Treatment Plant Receives $1.7 million Energy Grant

A new cogeneration system installed at the Budd Inlet Treatment Plant by the LOTT (Lacey, Olympia, Tumwater, and Thurston County) Clean Water Alliance late last year uses treatment by-products as fuel to generate electricity and heat energy. This renewable energy system, combined with an aeration blower retrofit currently underway at the Budd Inlet Treatment Plant, is expected to save LOTT more than \$228,000 per year in utility costs.

Blower Advancements for the Wastewater Industry

"The Numbers Don’t Lie". It’s a popular saying everyone has heard before, applied to a variety of situations – political statistics, figures backing up an athlete’s performance and budget data.

Thirty percent is a big number. Applied to the above scenarios, it could entail a landslide victory or a hitter gaining entry into the Baseball Hall of Fame. But just imagine, if the manager of a wastewater treatment facility were to trim 30 percent from their operating costs, he or she might also consider that a landslide victory of their own.

 

Protection Against Water Hammer Damage

One major problem that causes severe damage or system failure for any water treatment station is water hammer shock waves. “Water Hammer” or “Hydraulic Shock” is a pressure surge or shockwave resulting when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly (momentum change). The reversed momentum then continues to multiply the further it travels before being stopped.

Tubular Membranes Handle Oily Wastewater at Metaldyne

Finding the most effective, reliable and economical method for separating and concentrating die lubricant is no easy task for die casting plants – and the situation at the Metaldyne aluminum die casting plant in Twinsburg, Ohio was no different.
