Hey there! As a wastewater mixer supplier, I often get asked about the difference between submersible and non - submersible wastewater mixers. It's a crucial question, especially when you're looking to invest in the right equipment for your wastewater treatment needs. So, let's dive right in and break it down.
How They're Built
First off, let's talk about the design. Submersible mixers are built to be fully submerged in the wastewater. They're encased in a waterproof housing that protects the motor and other internal components from the water. This design allows them to be placed directly in the tank or basin where the mixing needs to happen. On the other hand, non - submersible mixers are installed outside the wastewater. They usually have a long shaft that extends into the water to do the mixing.
The waterproof housing of submersible mixers is a big deal. It's made from materials that can withstand the harsh chemicals and corrosive elements often found in wastewater. This means they're less likely to break down due to rust or chemical damage. Non - submersible mixers, while they don't have to deal with direct exposure to the wastewater, still need to be protected from the environment around the tank. They might need a weatherproof enclosure if they're installed outdoors.
Installation and Placement
When it comes to installation, submersible mixers are relatively easy to set up. You just lower them into the tank and secure them in place. They can be installed at different depths depending on your mixing requirements. Some can even be mounted on a guide rail system, which makes it super easy to remove them for maintenance or inspection.
Non - submersible mixers, however, require more complex installation. You need to build a support structure outside the tank to hold the mixer. The shaft needs to be properly aligned to ensure efficient mixing. And you have to make sure the shaft is long enough to reach the right depth in the tank. This whole process can take more time and labor compared to installing a submersible mixer.
Mixing Performance
In terms of mixing performance, both types have their pros and cons. Submersible mixers are great at creating a high - intensity mixing effect. Since they're right in the middle of the wastewater, they can quickly and efficiently mix the contents of the tank. They're especially good at keeping solids in suspension, which is important in wastewater treatment to prevent sedimentation.
Non - submersible mixers, on the other hand, can cover a larger area. Their long shafts allow them to reach different parts of the tank. They're often used in larger tanks where a more widespread mixing pattern is needed. But because they're not directly in the water, they might not be as effective at creating a high - energy mixing zone as submersible mixers.
Energy Efficiency
Energy efficiency is another important factor. Submersible mixers are generally more energy - efficient. Since they're directly in the water, they can transfer the energy from the motor to the wastewater more effectively. There's less energy loss due to friction or air resistance. Non - submersible mixers, with their long shafts and external installation, might lose some energy in the process of transferring the power from the motor to the water. This can result in higher energy consumption over time.
Maintenance and Durability
Maintenance is a key consideration for any piece of equipment. Submersible mixers are relatively easy to maintain. Since they can be easily removed from the tank, you can quickly access the motor and other components for cleaning or repair. And because of their waterproof design, they're less likely to accumulate dirt and debris on the outside.
Non - submersible mixers, however, need regular maintenance on the shaft and the external parts. The shaft can wear out over time, especially if it's constantly in contact with the water. And the external components need to be checked for damage from the environment.
Cost
Cost is always a factor when making a purchasing decision. Submersible mixers tend to be more expensive upfront. The waterproof housing and the technology required to make them submersible add to the cost. But when you consider the long - term savings in energy and maintenance, they can be a cost - effective option in the long run.
Non - submersible mixers are usually cheaper to buy initially. But the cost of installation and the potential for higher energy consumption and maintenance can add up over time.
Applications
Let's talk about where these mixers are commonly used. Submersible mixers are often used in smaller tanks or basins, like in residential wastewater treatment systems or small - scale industrial plants. They're also great for applications where a high - intensity mixing is required, such as in Submersible Mixer for MBBR Tank where they help keep the media in suspension.
Non - submersible mixers are more commonly used in large - scale wastewater treatment plants, like municipal facilities. Their ability to cover a large area makes them suitable for these big tanks. They're also used in applications where the wastewater has a high concentration of solids, as their long shafts can reach deeper into the tank to mix the contents.
When to Choose Each Type
So, how do you decide which type of mixer is right for you? If you have a small tank, need high - intensity mixing, and want an easy - to - install and maintain option, a submersible mixer might be the way to go. For example, if you're dealing with a Submersible Reflux Pump application, a submersible mixer can work well to ensure proper circulation.
If you have a large tank, need to cover a wide area, and don't mind a more complex installation process, a non - submersible mixer could be a better choice.
Conclusion
In conclusion, both submersible and non - submersible wastewater mixers have their own unique features and benefits. Understanding the differences between them is crucial in making the right decision for your wastewater treatment needs. Whether you're a small business owner or part of a large - scale municipal facility, choosing the right mixer can make a big difference in the efficiency and effectiveness of your wastewater treatment process.
