Sewage sludge is filtered by grills, degritters, primary and secondary sedimentation tanks of wastewater treatment plants. Sewage sludge may contain many pathogens such as giardia, campylobacter, E. coli, salmonella, legionella, as well as various chemical contaminants.

There are multiple methods for sewage sludge treatment developed over the years and applied in various countries, such as incineration, drying and dewatering at fields or in geotextile bags for pathogens elimination. However none of the available methods of sludge treatment allow full utilization of sludge benefits as a natural resource. Sludge is rich in many organic nutrients that can be effectively used to benefit humankind.

The need for incineration has become an option with no alternative due to the lack of land for sludge long term storage for its disinfection. Long term storage of sludge at fields also carries a high risk for groundwater and reservoirs contamination, and becomes a source of stinking odor.

In case of sludge compliance to sanitary standards in terms of heavy metals content, such sludge may undergo antimicrobial treatment by electron beams, and further used as fertilizer in agriculture.

The process of sludge treatment by electron beam irradiation against pathogens and chemical contaminants has high capacity which can be compared with incineration by its speed, and it enables us to get the best out of sludge to the humankind's benefit..

Modules may be installed at wastewater treatment plants, as well as sludge landfills..

It's also worth pointing out that there's no residual radiation in sludge post treatment by electron beam radiation, which makes it completely safe for agriculture application and urban greening.
Modules installed at wastewater treatment facilities and sludge landfills are used for sludge treatment, which can be further used as organomineral fertilizer. A wide range of microelements remains in sludge after treatment, which makes it a valuable fertilizer in agriculture or may be used as topsoil in urban greening.
Ionizing radiation technology makes it possible to
  • Turn the sewage sludge stored at landfills into a valuable fertilizer;
  • Vacate landfills and carry out antimicrobial treatment of the area;
  • Provide natural fertilizers with no chemical contaminants to agricultural companies;
  • Carry out antimicrobial treatment of sewage sludge at wastewater treatment plants and provide the treated sludge as fertilizer to agricultural companies;
  • Decrease costs for sludge incineration;
  • Decrease atmospheric pollution from incineration process;
  • Decrease the use of chemical fertilizers in agriculture.
Treated sludge may be used as:
Fertilizer for agriculture
Topsoil for urban greening purposes
