Mixing 101: The Importance of Specific Gravity

What is Specific Gravity? And why do we ask for it… Next to viscosity, specific gravity is a separate but equally important factor in optimizing a mixer. Without factoring this measurement into your mixer design, your results would not reach product specification. What is Specific Gravity? The term “Specific Gravity” (SG) is used to define the weight or density of a liquid as compared to the density of an equal volume of water at a specified temperature. The temperature used for measurement is usually 39.2oF (4oC), because this temperature allows water to assume its maximum density. In the metric system, water has a density of 1 gram/ml, so density and SG are numerically equal. If the liquid you are comparing

Dynamix Products

The History of Dynamix Agitators Inc.

Our Way of Doing Business Way back in 1962, a young man sold his first mixer ~ and a life-long passion for the design and engineering of industrial mixers was born… Established in the early 1970s, Dynamix Agitators initially operated as a pump and mixer distributor under the name Industrial Pumps & Mixers. Through many years of working on large projects with leading mixer manufacturers, the company developed a strong understanding of the science behind industrial mixing, and a deeper understanding of the key pain points that customers faced. In an industry not known for rapid innovation, Dynamix leveraged decades of engineering expertise to develop an innovative new line of mixers that addressed the common limitations seen throughout the mixing industry. From process, to

Mixing 101: Optimal Tank Design

UNDERSTANDING HOW TANK DESIGN AFFECTS MIXING Apart from the actual mixer, the design of the mixing tank is the single most important factor in producing a successful result in any process. In order to allow optimal performance from a mixer’s impeller, it is essential to create an environment that supports both correct impeller positioning and appropriate liquid coverage of the impeller. Incorrect positioning negatively affects the performance of a mixer, the quality of a product, and may even be detrimental to the performance life of the mixer drive. When looking at tank designs, vertical cylindrical, and square or rectangular tanks are most common. In the process of selecting the optimal tank design for an application there are certain rules of

6 Cool Mobile Apps for Water & Wastewater Professionals

In a world where phones are getting smarter every day, it makes sense to put them to work wherever we can. Our devices are with us 24/7, and with the right apps they can be customized to take over many regular job tasks while on the go. These days there are apps designed to assist in every conceivable function, and the water and wastewater treatment industry is no exception. Smartphones can unchain you from your desk, and eliminate the need to run back to the office every time you need to check measurements or perform calculations. Mobile apps are often free, but even when they aren’t, the value they provide is usually well worth the investment. You can’t put a

Mixing at Home: What Do Gravy and Mixing Have In Common?

The Secret to Great Gravy? Thinking In Terms of “Good Mixing” Is there anything better at turning a good holiday meal into a truly great one than a lake of delicious gravy? We have all been caught us all off guard by lumpy, pasty tasting gravy at least once. Usually after we have already covered our turkey and mashed potatoes with it. Thick, rich, and flavourful gravy doesn’t come easy, but properly mixing dry powders with liquids is a simple concept that just takes a little finesse to perfect. If you think about making gravy in terms of “good mixing” you can’t go wrong. First, you only need about 1/4-1/3 cup of holiday bird or roast drippings, being careful to

Mixing 101: Baffled by Baffles?

Mixing 101: Baffled by Baffles? How Baffle Configuration Can Optimize Industrial Mixing In our previous posting on configuring your mixer, we learned that the tank type and volume, viscosity, specific gravity and the process are key factors the mixing process. In this article, we dive into how baffle configuration and mixer mounting can prevent the undesirable flow pattern of swirling. Let’s look at a common tank configuration: an un-baffled cylindrical tank. If a mixer is center-mounted in this tank, what we see is a very inefficient flow pattern: the tangential velocities coming from the impeller cause the entire fluid mass to spin (Fig. 1). Basically, the entire fluid (and its solids) moves like a merry-go-round. In solid suspension applications, the solid
