The aeration efficiency projects involve the application of simple but effective measures to reduce air requirements in order to cut operational expenditure. This involved reducing blower/mixer usage and predictive restriction of dissolved oxygen requirements.

These simple measures have proven to be very effective in reducing energy usage and can be developed and commissioned for a fraction of the cost of more complicated ‘blackbox’ aeration control systems. In several cases the total cost of development and installation is recuperated within the first 6 months of operation.

This makes our aeration efficiency solution suitable for all sizes of plant, whereas the more complex ‘blackbox’ aeration control systems require a large site in order for the benefit to justify the cost. In addition, we offer tailored software modifications to suit the specific site which requires no extra hardware costs, rather than a generic solution that does not consider each site’s specific requirements.
