Blower features that will optimize your aeration process
Properly aerating your wastewater treatment plant is tricky. It is even more difficult if you want to make sure that you are doing so sustainably. Let’s get a bit more technical. Which innovations should you look for when you’re aiming for operational excellence? Separate air intakes for the cooling and process air, integrated filters, modulation blow off valve and a local controller are a few features to look out for if you want to optimize your process.
An efficient air flow
The incoming process air needs to be separated from the cooling air. That means it does not have to be preheated. This results in lower discharge temperatures. The separate air intakes make your operation more cost-efficient. The lower the temperature of the air, the more oxygen it contains and adds to the water. With a low discharge temperature, you’ll need less air and thus less energy. In addition, your units can easily be adapted to allow the ducting of the process air from outside the blower room. This ensures a more stable/reliable blower operation – even in changing ambient conditions.
No separate air inlet filters needed
Using integrated high-capacity filters, the process air is then completely filtered. This guarantees that particles and dust do not make it into your diffuser or tanks. At the same time, it eliminates the need for an on-site installation of separate air inlet filters. That saves you valuable time and prevents a potential incorrect installation from damaging or contaminating your blower or downstream components.
Efficiency, connectivity and ease of operation
One special characteristic of wastewater treatment plants is that the aeration demand fluctuates greatly depending on the season or even the time of day. A big turndown ensures that you can easily cope with large process fluctuations.
Integrated Variable Frequency Converter
A common method used to have a variable flow supplied by the blower is to change the main motor speed to match the process requirements. Integrating a variable frequency converter assures you of the correct operation of both the motor and frequency converter for the full operating range of the blower. On top of that, you’ll be able to have wider turndown available from each blower.
Blow off valve
One feature to look for is the modulation blow-off valve. It will not just open and close to accommodate minimum flow conditions. Instead, it continuously controls the flow to support your treatment process at any time.
Monitoring different parameters
A local controller allows you to easily change operating parameters and facilitates more stable processes. In addition, a local controller ensure you can follow certain process parameters and offers further machine protections in case of unexpected situations.
Advanced diagnostic services will offer you recommendations on how you can optimize the performance of your equipment and reduce the energy it consumes.
