Reservoir sedimentation is a process of erosion, entrainment, transportation, deposition and compaction of sediment carried into reservoirs formed and contained by dams. It may be formed and carried naturally by rivers or be a result of waste disposal.

This accumulation is a serious problem in many parts of the world and has severe consequences for water management, flood control, and production of energy. And moreover sediment in reservoirs is also contaminated with pathogens, and that creates a threat for human health.

Sediment may contain E. Coli, saprophytes, Clostridium perfringens, enterococci, and other pathogens.

Sediment is removed from reservoirs conventionally by dredging. The extracted sediment undergoes antimicrobial treatment by electron beam irradiation, and may be then provided to agricultural companies to be used as fertilizer.

Electron beam treatment damages DNA of pathogens thus ensuring safety of the treated sediment as a fertilizer.

Sediments contain a wide range of nutritional elements and can be an excellent fertilizer known as sapropel which is often used in agriculture.

Benefits of electron beam treatment of reservoir sediment:
Environment friendly treatment method with no application of chemicals;
The portable module may be placed in close proximity to reservoirs that allows cutting costs for transportation of sediments for treatment elsewhere.
