Water treatment
Dechlorination
Flow-paced neutralisation to reduce residual chlorine before discharge, with the target residual and operating basis governed by the site approval.
Who this is for
Water utility operators, commissioning contractors and discharge managers
Your operating priority
Plan residual chlorine treatment around the actual receiving environment and release conditions.
Before you specify or buy
Confirm residual chlorine, volume, flow and applicable limits; define verification sampling and treatment controls before any release decision.
What is covered
- Review chlorine residual, flow variation and the intended discharge point.
- Scope flow-paced chemical neutralisation and suitable monitoring points.
- Consider dosing control, mixing, alarms and safe chemical handling.
- Define acceptance criteria and verification sampling against the relevant approval.
What we will ask you
- Residual chlorine data and expected flow range
- Discharge approval requirements and target residual
- Dosing point, mixing conditions and existing control equipment

Frequently asked questions
- What must a commissioning contractor check before discharging chlorinated water?
- Establish water volume and flow, the chlorine residual and the applicable receiving-water and release conditions. Scope treatment and verification sampling before discharge. Selecting a dechlorination chemical or observing no chlorine smell does not establish that release is permitted.
- What target residual should the system achieve?
- The target is determined by the applicable approval and discharge requirements, not a universal value.
- Does flow-paced dosing ensure the target is met?
- Flow pacing can support control, but verification depends on mixing, residual measurement, changing conditions and site operation.
