Static Mixers for Drinking Water: A Vital Component

Static Mixers:

Static Mixers for Drinking Water: Effective disinfection of drinking water supplies is essential for safe operation.  Relying on natural turbulence alone in a pipeline will not guarantee complete mixing of injected chemicals at all times, especially where low flow rate conditions occur and where automatic process control of chlorine residual is implemented.

Unreliable sampling and excessive time delays between injection and sampling result in:

• Under dosing (unsafe operation)
• Overdosing (unsafe operation and waste of chemicals)
• Unstable control of chlorine residual (unsafe operation and waste of chemicals)
• Plant start up difficulties (hunting of process control)

Motionless Mixers:

Statiflo Motionless Mixers are a vital component in all inline mixing/process control application systems.  Designing the system to achieve representative sampling is essential for accurate and responsive process control of chlorine residual or any other critical property.  Even the most sophisticated process control equipment will be ineffective if mixing and sampling techniques are not carefully considered.

The Statiflo Motionless Mixer ensures complete mixing either at the mixer discharge or at a predetermined downstream location.  Complete mixing allows representative sampling from a single point at the pipe wall either from the mixer or immediately downstream.  The distance between injection and sampling is minimised, the time lag in the control loop is also minimised.  The result is a more effective process control, minimising both overdosing and under dosing of injected side streams.
