APTwater regularly conducts process bench testing to validate the performance of our process technologies for a specific site or application.
In conducting a laboratory bench test, we collect site-specific chemical and physical data to profile the water source. Test parameters may include chemical and biological oxygen demand, pH, hardness, dissolved oxygen, and alkalinity, among others. We also subject samples to simplified, bench-level treatment schemes in our corporate treatability lab to collect information for treatment design, equipment sizing, and consumables demand. A 5-10 gallon water sample is usually sufficient for testing purposes. Chemical analyses are performed by an external laboratory. Bench test reports are prepared that define the scope of the analysis, test results, and full-scale design implications.
A bench test consists of a series of individual tests performed at different oxidant dosing conditions. The resulting data is used to produce a 'destruction curve' that is specific to the contaminant concentrations and water quality conditions of your site. This 'chemical fingerprint' of your site is then the basis for our engineering design effort. The result is a process design with a performance guarantee to meet your specific needs.
