Odour & H2S Control

Odour emission forms a serious problem for people living close to or work in area’s releasing odour. These sites can be manufacturing plants, wastewater treatment plants, pumping stations, landfill sites or waste processing facilities but also agricultural sites like pig and poultry stables. Even the local take away restaurant emitting the cooking odours into the atmosphere can form a problem.

Certain odour compounds, like H2S or organic solvents, form a direct risk for human health. Others are initially unpleasant and cause health complaints to people who are exposed to them over a longer period of time. Local authorities are getting tougher on odour emission and odour control measures are required more often when odour is emitted.

QM Environmental Services Nederland offers a range of products and systems which can be applied to control odour emission or neutralize odours once they are emitted into the atmosphere.

The products offered by QM Environmental Services Nederland in the field of odour and H2S control comprise the MicroCat® microbial formulations, Dry Vapour Odour Control installations and QM-Bioactivators.

These products are successfully applied in the following situations:

  • H2S-control in sewers, pumping stations and wastewater treatment plants
  • Odour control at waste processing and composting sites
  • Odour control in grease traps
  • Biofilter start-up and maintenance
  • Pig and poultry stables
  • Manure depots
  • Sanitary facilities like public toilets

A microbial liquid for odour and H2S control in sewer lines, pumping stations, wastewater treatment plants, sludge storage, composting facilities and deodorisation of surfaces. Prevents the formation of H2S and odour in a biological way.

Dosing units for automatic dosing of MicroCat®-ANL in  pumping stations and wastewater treatment plants.  Available as rental or purchase.
A microbial powder containing bacteria which liquify solidified manure crusts and reduces odours.
An completely natural product which is applied on the living floors inside pig and poultry stables by nebulisation.

The ingredients of QM-BioStable activate naturally occurring bacteria, present in the manure, to rapidly convert organic matter and ammonia. This reduces the emission of odours caused by ammonia and improves the air quality inside the stable. The improved air quality results in an animal health improvement, requiring less antibiotics, less mortality and heavier animals at the end of the growth cycle.

An innovative odour control system for odours emitted into the atmosphere. The unit relies a technology by which an odour neutralising agent, Oxi-Max, is emitted in a dry vapour form into the atmosphere where odour is emitted.

The Dry Vapour Unit (DVU) is applied in both indoor as outdoor situations. The DVU is available in different capacity sizes, which allows for small or large sites being deodorized.  The DVU is applied in the following situations:

  • Restaurant kitchens
  • Wastewater treatment plants
    • Buffer tanks
    • Slib storage and dewatering facilities
  • Composting & waste processing facilities
  • Garbage trucks
  • Soil remediation sites
  • Pig & Poultry stables
