Mixing 101: Torque and the Art of Mixing

What is torque… and what does it have to do with mixing? Selecting a mixer drive with a high horsepower rating doesn’t guarantee a satisfactory result in your application, and it doesn’t necessarily translate into a more powerful mixer either. Horsepower is merely a measurement of the rate at which work is done – or how much input power a motor has. Simply throwing more horsepower at an application may make a mixer’s impeller turn faster, but it will also drive down efficiency, negatively impact your budget, and can even damage your product through shear. If the driving force of a mixer is rotational, then horsepower is secondary to torque as the force that drives the pumping and performs the

Mixing 101: Optimal Mixer Design

4 FACTORS FOR OPTIMAL CONFIGURATION Getting the right mixer for the job involves so much more than simply purchasing a standard unit off-the-shelf. There is an art to configuring a mixer that will optimize the results of an application. Selecting a mixer based solely on horsepower or RPM requirements can produce less than optimal results, and even damage your product through excessive shear. As we discussed in an earlier post, we first need to understand the 4 Factors for Configuring a Mixer, which are: Tank Type & Volume Fluid Viscosity Specific Gravity Environment & Process Once a Dynamix Sales Engineer understands these factors in relation to your application needs, we are ready to configure a mixer that will both maximize your investment

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

Optimizing an Anoxic Mixer for Denitrification

Optimizing an Anoxic Mixer for Denitrification in Water Treatment Simply adding bacteria to a wastewater plant does not guarantee that they will achieve the targeted task of denitrification. To encourage their growth, it is essential to first establish an anoxic environment, and then introduce an anoxic mixer that has been optimized specifically for the process. The Denitrification Process Denitrification in wastewater treatment is the conversion of nitrate (N03) to nitrogen gas (N2). It is a process that involves the reduction of nitrogen present in waste streams to an acceptable level so the treated water can be discharged into the environment via streams, ponds, lakes, etc. Lowering nitrate levels in a waste stream is achieved through creating an anoxic environment in which heterotrophic

Keeping Your Solids in Suspension

Optimized Solids Suspension Applications Achieving a uniform dispersion of solids in a product is critical to your product’s quality. In processes that mix solids in fluid, particulates that cannot dissolve in liquids will either sink to the bottom of the tank and collect in the corners, or stick together and agglomerate. This compromises product uniformity (product quality), and in extreme cases, can cause a system to malfunction or fail. The main objectives of solid and liquid solutions are: Avoiding solids accumulation in a stirred tank Maximizing the contact area between solids in a liquid Ensuring the solid particles are uniformly distributed throughout the tank The goal is to bring the mixture into specification and keep it there. This means keeping

Neutralization Mixing for pH Control

Neutralization Mixing for pH Control Wastewater Treatment Neutralization Neutralization, also known as pH control, is the process of adjusting or maintaining a desired pH level in the wastewater. Generally, neutralization involves the introduction of chemicals to bring water to a neutral pH of 7.0: Acids with a pH less than 7.0 are used to lower the pH of a tank of basic liquid Bases or caustics with a pH higher than 7.0 are used to raise the pH of a tank of acidic liquid The objective of neutralization is to bring effluent wastewater to a neutral pH of 7.0, meaning neither acid nor base, making it suitable for discharge. The acceptable pH level of the discharge varies by location and
