Clay treaters are usually placed upstream of a filter separator system to remove surface active agents (surfactants), color and additives from jet fuel. These unwanted contaminants may be present in fuel at the processing and refining levels or picked up from various transportation methods (trucks, ships and pipelines that carry several types of petroleum products in addition to jet fuel). The contaminant compounds will accumulate and disarm the coalescer cartridge and reduce the water coalescing efficiency of the filter separator. Clay treaters provide a complete adsorptive system that removes the surfactant compounds, color and additives and delivers treated fuel while also prolonging cartridge life of the downstream filter separator. Clay treater housings have no internal moving parts. Housings are designed for easy servicing and low maintenance. All are built to ASME Code, Section VIII. Standard and optional accessories and connections are available to facilitate piping and installation requirements.
