Mixing 101: Low rpm, High Torque Mixing

Mixing 101: Low rpm, High Torque Mixing In the process industry, there’s a strong focus on power as the defining characteristic in mixing. Many considerations are often left by the wayside when choosing a mixer. These factors can make or break the application. Relying solely on the G-Value or velocity gradient in mixer design leaves important information out of the equation. Focusing on the G-Value gives rise to the misconception that horsepower, rather than torque, is the critical factor determining mixing effectiveness. This method is effective for applications requiring high-sheer and turbulent flow, but this isn’t always the case. High-speed mixing introduces a host of additional considerations based on fluid viscosity, flow patterns, and shearing. Mixing Categories Different types of

Mixing for Dissolved Air Flotation (DAF Systems)

Coagulation, flocculation and flotation systems Dynamix is often called on for its process experience in many industries because the mixer is at the heart of these processes. DAF systems are used across many industries with many unique requirements which Dynamix is familiar with. There really isn’t a one size fits all or a configuration template that works for all processes when it comes to DAF systems. Ideally, the Dissolved Air Flotation (DAF) process is used for thickening of combined primary and secondary sludge removing low-density materials such as microorganisms (algae, cysts), natural organic matter (NOM) and floc in low turbidity, soft waters (typically using coagulation and flocculation). Typically, DAF systems are a faster and more reliable alternative to sedimentation in the clarification

Anoxic and Aerobic MBBR Mixing

Moving Bed Biofilm Reactor MBBR Mixing Process Anoxic & Aerobic MBBR Mixing Proper mixing within anoxic and anaerobic MBBR zones can improve the bioorganic nutrient conversion processes, minimize operational footprint, reduce energy costs and improve water treatment efficiency. The Moving Bed Biofilm Reactor (MBBR) or IFAS (Integrated Fixed-film Activated Sludge) technologies are now more commonly used to maximize the efficiency in treating wastewater from industrial applications that produce high concentrations of BOD, COD and TSS. This newly adopted technology has become more efficient than traditional biological wastewater treatment processes capable of achieving nearly complete nitrate/nitrite-nitrogen (NOX-N) reduction. It also reduces water treatment plants footprint by minimizing stages previously required to filter BOD from biosolids. The MBBR Process In short, MBBR is

Waste Activated Sludge Mixing Principles

Why Is Sludge Blending Important? For many industrial wastewater treatment facilities, sludge accounts for as much as 30-40% of capital costs and about 50% of the operating costs due to the complex nature of processes involved to curb by-product waste. The sludge or “bio solids” left over can be refined into nitrate based fertilizers/ compost, chemical bio-fuels or other natural resources. Sludge biosolids can also be further dewatered for post processing and disposal purposes and because of the many products that can be economically produced; the sludge process is a true bio-refinery. Many water treatment plants focus on improved quality within their operations of sludge handling and mixing equipment selection. Sludge viscosities have an influence on e.g. pumping, hydrodynamics, mass transfer

Key Factors to Lime Slurry Usage in Water Treatment Processes

LIME SLURRY USAGE FOR WATER TREATMENT PROCESSES FACTORS TO CONSIDER What is Lime? Not to be confused with the lime you find in your local produce store, Lime is a commonly used chemical for wastewater treatment and can be slaked when water is added and turned into slurry. The use of lime in its various forms has been steadily on the rise. Today lime is the most important chemical used throughout the world for pollution control. It is, therefore, imperative that handling and processing lime be well understood by all those who use this chemical. The Lime used in the water treatment industry is referred to as either quicklime (CaO) or hydrated lime (Ca(OH)², which is hydrated in

Mixing 101: Air vs. Electric

5 FACTORS FOR OPTIMAL MOTOR SELECTION Air or electric? End users often don’t understand all the factors to consider when making the decision to use an air motor vs. an electric motor in their mixer configuration. While a mixer’s motor type is largely determined by the plant environment, the value of considering several important factors is substantial when each consideration point is thoroughly understood. A proper understanding of torque, energy efficiency, variable speed, mixing environment, and mixer weight are all significant and valuable considerations to discuss when selecting an appropriate motor. In a real-world example, our engineers leveraged these factors when working with a leading car manufacturer, and the decision to make a wholesale change within their production environment not
