Chromatic Elemental Imaging℠

A distinct advantage of Chromatic Elemental Imaging (CEI) is its ability to provide insight into the layering characteristics of foulants deposited on a membrane. By analyzing the layers, it is possible to understand the fouling sequence. When used in combination with Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX), CEI can reveal the interaction between inorganic, organic, metal oxide, and colloidal compounds.

As a troubleshooting tool, CEI is unmatched in its ability to successfully determine the primary membrane foulants, which can help identify process deficiencies to prevent or minimize future fouling. CEI has also accelerated the development of new antiscalants, cleaners, and biocides by replacing the process of trial and error with scientific validation of formulations targeting specific foulants.
