Ydro process in the sewer grid

Applying the Ydro process in the sewer grid: the sewer system is turned into a pre-treatment reactor where facultative/aerobic conditions allow:

  •  The degradation of the organic load which can occur up to 80% (<100 mg/lt COD). The wwtp requires less energy and time to treat the remaining load.
  • Eliminates the city odors (grid, manholes,pumping stations) The Sulphate Reducing Bacteria contained in the Ydro Series products, do not allow the formation of Hydrogen Sulphide (H2S) which creates the odours
  • Degrades Fats/Oils/Grease
  • Cleans out the grid, manholes and pumping stations and no  cleaning or unclogging is required
  • The Sulphate Reducing Bacteria contained in the Ydro Series products, do not allow the formation of Sulphuric Acid (H2SO4) which induces the corrosion of the sewer pipelines. This way huge investments of replacing the pipelines are avoided.

Technical details

The Ydro Process® is the continuous adaptation of selected microbial population to the local operating wastewater plant conditions and parameters according to the targets. The added bacteria become dominant and the existing ones are adapted and assimilated to coexist and collaborate. In suitable conditions the added microorganisms produce enzymes which enhance the biological process. The degradation of complex organic molecules, oils and greases into simple ones leads to the production of Volatile Fatty Acids (VFAs), i.e. Acetic, Butyric, Propionic Acid etc. The VFAs are then easily converted to Carbon Dioxide (CO2) and water (H2O) in aerobic conditions, methane (CH4) and hydrogen (H2) in anaerobic conditions and free available energy. The application of these microorganisms in wastewater treatment plants results in the enhancement of the system performance and the control of the processing, increasing the system’s efficiency with the following results:

  1. Total degradation and elimination of the excess sludge
  2. Improvement of the effluent of the plant (BOD,COD,SS,TN,TP etc)
  3. Liquefaction and elimination of fats in the treatment plants and in pumping stations
  4. Elimination of odors
  5. Possible reduction of the energy consumption in the aeration stage
  6. Possible increase in the biogas production with a simultaneous increase of methane content in it
  7. Significant reduction of micropollutants
  8. Higher resistance to incoming organic shock
