Centrifugal separators provide liquid/solids or liquid/liquid separation at various stages in many separation processes, from course separation to ultra-clarification. Typically solids removal is using a clarifier, whereas liquid/liquid is using a separator.

When installed at three primary points around the centrifuge, inline photometers have proven to greatly improve separation performance, reduce losses and improve product consistency.

Centrifugal (Centrifuge) Separation Benefits |
- Reduced Product Losses
- Increased Separation Performance
- Optimized Product Quality
- Maximize Throughput / Increased Yields
- Reduced Rework
- Avoid Downstream Filtration Blinding

| Feed |
The feed stream sent to a centrifugal separator will often have highly variable solids loading. Separation efficiency can be greatly improved by installing an optek AF or AS series Near Infrared (NIR) sensor in the feed stream prior to the separator. The separator feed rate can then be optimized, based on real-time solids concentration measurements. Overloads can be detected and diverted preventing shut downs.
|
Using data from the optek instrument bowl speed, feed flow, or both can be controlled in a dynamic control loop. At maximum clarity, the separator can be fed with full flow. As the solids concentration increases, the flow can be reduced proportionately or in fixed steps. This provides optimal separation and throughput without overloading the separator. Overload situation can be detected and diverted preventing system shut downs.
|
| Centrate |
The separator outlet (centrate) is the most common point of installation for process photometers. To optimize separation performance and protect downstream filtration equipment, choose an optek TF16 turbidimeter for low concentrations, an optek AF/AS-N series NIR sensor for percent-solids monitoring, or a TF16N hybrid for dual-range applications.
|
| Concentrate |
When measuring solids at the concentrate stream of the separator, an optek AF/AS-N series sensor, equipped with a very short optical path length, will accurately correlate absorption measurements directly to weight-percent. This enables accurate yield measurement and control of product quality.
