Technical guide for initial assessment. Every installation needs validation of its own data.

Effluent is not a fixed formula

Two plants with the same flow can have very different ozone demands. Dissolved compounds, solids, color and production changes alter consumption and reaction time. A dose borrowed from another project can therefore produce an undersized or oversized system.

What a test should answer

A useful test compares representative samples under different dose and contact conditions. It should measure the parameters that motivated the project rather than simply observe a visual change. In pilot testing, we study contaminants, estimate ozone demand and use the result to size equipment before investment.

Prepare samples and criteria

Define the outlet goal and normal operating range first. Gather recent analyses and, if effluent varies, samples from different shifts or seasons. Agree on parameters, laboratory methods, detection limits and acceptance criteria. The pilot should represent the water the full-scale plant will receive.

From test to plant

Laboratory results guide required output, but final design also considers gas transfer, hydraulics, contact time, automation and safety. A serious proposal explains how pilot results become installed capacity and what uncertainties remain. If water changes over time, operation needs suitable control and design margin.
