Selecting Wastewater Mixers for Wastewater Treatment – Part 1

Selecting Wastewater Mixers for Wastewater Treatment – Part 1 Wastewater Mixers for Optimal Chemical Preparation Chemical preparation in wastewater and water treatment directly impacts many downstream processes. Let’s take a look at several common chemicals used and some key factors that influence their preparation and the selection of wastewater mixers. Lime Slurry Preparation When preparing lime slurries for controlling pH, uniformity is critical. Why? Because lime solids must reach/stay in suspension if they are to serve their purpose in downstream processes. For this reason, it’s essential that wastewater and water treatment facilities have lime slurry mixers that can efficiently and effectively make up/maintain uniform slurries. In order to successfully suspend/re-suspend solids, a mixer needs to create a flow pattern that involves the entire

Selecting A Waste Water Mixer for Wastewater Treatment – Part 2

Selecting A Waste Water Mixer for Wastewater Treatment – Part 2 Waste Water Mixers for Optimal Flash Mixing & Flocculation In part 1 of this series on wastewater and water treatment mixers, we discussed how to select a waste water mixer for chemical preparation. In this post, we’ll show you how to select a Waste Water Mixer for flash mixing and flocculation. Done in a Flash? Aggressive Agitation + Speed for Flash Mixing Flash mixing is used to evenly distribute coagulating chemicals in water, allowing micro-flocs to form. As the precursor to flocculation, flash mixing increases the efficiency of flocculation and reduces chemical wastage. Because the components need to be quickly and evenly dispersed, this process is all about brute

Mixing 101: 4 Factors for Configuring Your Fluid Mixer

Mixing 101: 4 Factors for Configuring Your Fluid Mixer Considering Mixer Configuration If you’re in an industry that includes fluid mixing in its processes, you probably know that finding the right fluid mixer for your needs is critical to maintaining quality control, reducing costs, and optimizing efficiency. The key here is to engineer a fluid mixer that addresses the specific needs of your process. When configuring a mixer for your process, your mixing engineer should consider the following 4 factors: Factor #1 – Tank Type & Volume This determines the amount of fluid your tank can hold. This is important because it will determine the size and position of the fluid mixer and its mounting. Factor #2 – Viscosity This

Optimize Industrial Mixing with Proper Mixer Mounting

Optimize Industrial Mixing with Proper Mixer Mounting Challenges of Mixer Mounting In a perfect world, the only industrial mixing projects we would ever work on would be applications in cylindrical tanks where we could center-mount the mixer. That, of course, is not typically the case. Instead, factors such as environment, process design, tank design, and process objective require different mounts. For this, we offer our 40+ years of experience and engineering to develop mounting options to address almost every eventuality. Ultimately, the mounting option is dictated by the need to manage the reactionary force generated by the mixer’s torque at the fluid level inside the tank. High viscosity liquids, or large volume tanks that require large diameter impellers, are examples

Mixing 101: Flow Patterns & Impellers

Mixing 101: Flow Patterns & Impellers Mixing Flow Patterns & Impeller Types In our article on 4 Impeller Types and Their Applications, we provided an overview on the most common types of impellers used in industrial mixing. Now we’ll go into more detail about each impeller type and their influences on the mixing process. Our focus on impellers is due to the fact that they are the part of the mixer that does the actual mixing: as they rotate they create fluid flow. These flow patterns are the primary considerations when designing a mixer because creating the right flow pattern is critical to achieving the desired result. The most common flow patterns in mixing are axial (down and up) and

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
