SDC in sanitation and effluent treatment
A technology capable of combining disinfection and oxidation in difficult waters — with design guided by organic load and the final destination of the effluent.
Established technical application
Bench, field, and municipal-scale studies show a technology that can be designed for different matrices.
A moleculemultiple engineering disciplines
Effluent is not a single type of water. Ammonia, organic matter, solids, color, and microorganisms change from season to season — and change the oxidant demand.
Chlorine dioxide has a history in effluent disinfection and can act where chlorine finds limitations. The most interesting gain lies in the possibility of designing combinations: ClO₂, chlorine in smaller proportion, membranes, UV, or other barriers.
Less dependence on a single barrier
Oxidant combinations allow distributing functions among disinfection, odor control, color, and specific compounds.
The matrix guides performance
Demand and contact time assays transform the organic load into a design parameter and reveal the best operational window.

What field studies teach
01
USGS and Ohio State evaluated ClO₂ in residential sewage systems and observed effective inactivation of various test microorganisms.
02
Comparative studies show how dose, time, organic load, and target organism can be combined to meet reuse criteria.
03
Byproduct research indicates advantages in reducing certain halogenated compounds and helps guide the chemistry of each matrix.

How to bring technology to operations
Characterize the matrix
Measure COD, solids, ammonia, pH, turbidity, and microbiological indicators before choosing any oxidant.
Perform demand test
Dose-response curves and contact time show where ClO₂ adds value and where another barrier needs to come in.
Validate the destination
Discharge, agricultural, industrial, or urban reuse have different criteria. Treatment needs to be based on the output requirement.
