DS SMITH Paper Mill in Zarnesti (Romania)

22 December 2020

Installation of 2 additional odor treatment devices at the process water treatment plant of DS SMITH paper mill in Zarnesti (Romania):

Treatment of a biological pond (primary treatment). Installation of 140 m of high-pressure spray ramp around the pond.


  • Stainless steel ramp 316
  • 1 nozzle every 1.5 m
  • Flow rate of 1 nozzle: 5 l/h

Creation of an anti-odor barrier between the source (pond) and the dispersion (neighborhood). This installation is controlled by a weather station.

Treatment of sludge by incorporating a reagent in the dehydration process.
The reagent is incorporated at low concentration: 0.5 L of the pure product / t of effluent sludge

This treatment ensures:

  • Odor control of sludge for 5 days (storage in skips in a dedicated area).
  • Deodorization of the processing building.
