Turbidity in the Real World |
 |
|
To effectively use a turbidity analyzer in an industrial process environment, many things must be considered. A turbidity meter must be rugged in construction, watertight, able to withstand process pressures and temperatures, yet read low-level concentrations of particles (PPM, or even PPB) free of interferences. It must also be easy to clean (clean-in-place if required), and be serviceable, requiring minimal maintenance.
The turbidity meter must be compatible with materials and solutions it comes in contact with. The turbidity meter must be reliable and repeatable if it is to be counted on for process information. Most importantly the measurement technique (Scatter angle) employed must be selected based on its effectiveness in capturing the process task at hand. Many instruments installed today are not capable of differentiating between normal and non-normal turbidity constituents, thus incapable of actual process control.

| Applications of Turbidity Meters as Analyzers and Monitors |
Turbidity meters monitor and in some cases analyze the condition of the liquid in the process. The advanced systems available today transmit this data in real time for true real-time automated process control, and offer an immediate capability to react to changing process conditions. Continuous data collection also serves as a historical record for QA/QC purposes.
Reliable, repeatable turbidity analyzers can then be further utilized to baseline process parameters and system performance across multiple process lines, even across multiple processing facilities. Well-placed turbidity measurement techniques will not only respond to changing process conditions, but can provide useful information to assist in troubleshooting any turbidity related process issues.
Turbidity meter applications include turbidity detection as in a solids break-out, or a carry-over of an undesirable constituent, separation and filtration monitoring and control, solids concentration, for dosing or biomass growth, interface between product phases, water quality, wastewater BOD, blending control of cloudifier agents, haze control, concentration, clarity and stability assessments.

| Turbidity Summary |
| Turbidity meters measure an optical property of liquids caused by particles and colloids in liquid. optek analyzers employ advanced techniques to suppress optical effects not caused by particles in the liquid, such as color, signal noise, stray light, or other environmental influences, making them a precise, repeatable tool to automate a process, while providing tremendous payback opportunities by improving process efficiencies and reducing product losses and waste. optek turbidity analyzers are designed to meet these objectives in a rugged, stable, reliable, and low maintenance package, designed for continuous use in a variety of industrial, sanitary, and biotech applications. ROI's of 6 months or less are common, and in virtually all cases optek turbidity meters will have an immediate impact on bottom line production costs. |
