How Concentration and Contact Time Define Treatment Performance In ozone system design, one concept governs whether a system will successfully meet its treatment objectives: CT. CT, defined as the product of disinfectant concentration and contact time, is the foundation of ozone process design. It determines whether a system achieves: pathogen inactivation oxidation of metals such as iron and manganese destruction of organics and micropollutants taste and odor control Despite its importance, CT is often misunderstood or oversimplified. In practice, achieving a target CT is not just a calculation, it is [...]
