For operators of existing wastewater treatment plants

Know when aeration replacement is worth the cost.

Independent testing helps you weigh your system’s current performance and running costs against the cost of replacement.

Is replacement the right next step?

Keeping ageing equipment can become expensive. Replacing it too early can be expensive too.

Rising running costs

Declining aeration efficiency can increase electricity use. Performance testing helps you assess whether your existing system warrants attention.

Uncertain replacement timing

Age alone does not tell you whether equipment needs replacing. Get evidence to support maintenance or replacement decisions.

Hard-to-justify investment

A major replacement needs a clear reason. Independent performance data helps you explain the decision and support your budget.

Evidence for your next aeration decision

Independent testing measures your system’s performance and provides a basis for comparing your options.

Keep operating

Assess whether current performance supports keeping your equipment in service.

Plan maintenance

Use the findings to discuss whether cleaning or maintenance could be an appropriate next step.

Consider replacement

Compare measured performance with operating and replacement costs to support the timing of an investment.

The right decision depends on your plant, your equipment and your costs.
