The Art of Mixing

The science in a range of technologies.
You want the precise, right technology for your mixing requirement. At the same time, there are many factors to consider in the decision making process. We understand the art of mixing, which is why we suggest you talk to us, and together we will identify the complexities within your mixing application in order to capitalize on the possibilities available to you.
 
For example, both a submersible mixer and a top entry agitator can be ideal solutions in an anoxic or a sludge tank. And, a long narrow tank may require a large number of mixers. These are just some of the considerations that go into developing a wealth of parameters that ensure optimum mixing performance by selecting the right mixer.
 
We have a broad range of mixers and agitators featuring a span of technologies to ensure that you have nothing but the best possible choice for your specific needs. Most importantly each and every type of mixer and agitator is intelligently built with standardized materials and components and a modular design to facilitate customization.
 
What does it all mean for you?
It means you can choose correctly because you have the possibility of making well-informed and intelligent decisions. It also means that you are never alone in your selection process, but have the possibility of working together with some of the best in the business to achieve results. And, it means you have the assurance that your decisions are based on extensive experience in combination with specially developed and validated Computational Fluid Dynamics.

The Art of Mixing – by Xylem
 
REALISE THE MIXING DUTY
Before you begin, you need to be very clear about your reasons for mixing. The most common mixing duties are liquid blending and solid suspension.
 
GET TO KNOW WHAT YOU’RE MIXING
The second question to ask yourself is what it is that you are mixing. Information about the physical and chemical properties of the liquid content is important when making a thorough selection of mixing equipment.
 
UNDERSTAND HOW LIQUIDS BEHAVE
It is also important to understand the internal friction of the liquid, if it differs substantially from water. Two major parameters which are used to describe internal friction are viscosity and yield stress.
 
NEVER UNDERESTIMATE THE POWER OF SIZE
In order to determine the right mixer size, the following parameters need to be established: mixing duty and expected result, liquid characteristics, tank geometry and installation restrictions.
 
CALCULATE THE REQUIRED MIXER THRUST
The mixing result is controlled by the strength of the overall bulk flow in many applications. Most mixing applications generate abundant turbulence and it is the strength of the bulk flow that controls the efficiency of the mixing. The amount of thrust supplied determines the level of bulk flow.
 
LAYOUT IS KEY TO OPTIMUM MIXING
Correct layout is one of the most effective means of obtaining successful and efficient mixing. For bulk flow controlled mixing duties such as solids suspension and blending, there are some basic principles to consider, for example:
For horizontally-mounted submersible mixers and jet mixers
• Allow the mixer jet to develop over a long distance.
• Place the mixer to facilitate smooth flow deflection to the tank boundaries.
For top entry mixing
• The lower impeller drives flow upwards along the walls, and must therefore obey strict bottom clearance criteria.
