Biological Odour Control Technologies

October 14th, 2016

Let micronutrients put an end to the odour problems of your wastewater treatment plant.

Does your production facility suffer from offensive odour? Let micronutrients put an end to the odour problems.

Where? Landfills, wastewater plants, transfer stations, food waste receptacles, garbage trucks, yard waste and food waste composting operations, sewer systems, and pumping stations.

If you are faced with the challenge of treating, separating and disposing of biosolids, you are aware that often a significant portion of operating costs is related to preventing offensive odours that create discomfort for operators and adjacent property owners.

But it doesn’t have to be that way. Plant-based micronutrients can help you terminate the offensive odour, while lowering your costs and improving your system.

This claim is based on scientific grounds.

Dissolved and solid organic waste is degraded by bacteria that are generally classified by their ability to survive and multiply in the presence, or absence, of oxygen:

Aerobic bacteria function in the presence of oxygen;

Anaerobic bacteria function in the absence of oxygen.

Facultative bacteria are able to function in either presence or absence.

Anaerobic sulphur reducing bacteria have been identified as the main source of offensive odour compounds in organic processes and organic waste treatment systems. These bacteria are active and thrive in the absence of oxygen.

Anaerobic and facultative bacteria convert a much larger proportion of organic compounds to gases, rather than to new biosolids. In the anaerobic process, methane producing bacteria and sulfate reducing bacteria compete for available dissolved organic compounds, producing hydrogen sulfide and/or methane and carbon dioxide.

The generation of hydrogen sulfide (a noxious gas) and ammonia by certain anaerobes causes odour and has the potential to cause problems for adjacent property owners, discomfort for operators and corrosion issues with plant equipment.

Plant-based micronutrients specifically stimulate aerobes and anaerobes and competitively inhibit the sulphur and ammonia forming bacteria and enzymes. The main active ingredients in the micronutrient solutions include plant-sourced amino acids, vitamins and other plant-based organic constituents and trace minerals. The micronutrients solution itself is biodegradable as it is used up by the beneficial bacteria as a food source found in organic waste streams.

These micronutrients, when added to liquid and solid organic waste streams, eliminate the formation of odours at the source, i.e. in the biological reactions that are responsible for organic waste degradation.

The biological reactions at work, when certain micronutrients are added, impact the metabolic rate of certain microbial organisms. Research has shown that non sulphur reducing anaerobes and many different types of aerobes are stimulated by the plant based organic micronutrient catalyst to operate at much higher metabolic rates. Sulphur reducing anaerobes and ammonia generating enzymes are unable to utilize the specific micronutrients introduced into organic waste streams.

As a result, the microorganisms stimulated by the micronutrient solution, compete with  the odour producing microbes for macronutrients and thereby, by means of competitive inhibition, severely restrict the odour producing microbes in their metabolic activity resulting in a dramatic decrease in the production of odourous gases.

The net impact is that odours are significantly reduced but bacterial breakdown of the organic waste continues at an accelerated rate.

The use of plant-based organic micronutrients represents a near zero carbon footprint solution to eliminate odours from most, if not all, facilities faced with odour control and odour mitigation strategies.

There is an immediate return on investment for micronutrient usage as it replaces or eliminates the costly operation of bio-filters, ozone units and oxygen units.

Specific plant-based organic micronutrients have been used worldwide to reduce energy costs associated with oxygen supply to the bacteria, decrease sludge generation, reduce odours and improve treatment efficiency.

Plant-based organic micronutrients can also be utilized in misting systems to treat odourous gases generated by nonpoint sources of odours in facility operations like transfer stations, landfills, garbage rooms in commercial facilities, wastewater plants, bio solids processing facilities, and organic material processing  facilities like food production plants and/or pulp and paper mills.

These micronutrients can also be used to improve capacity and performance of bio-filters and wet scrubbers.

The plant-based micronutrients described in this article are manufactured and sold by SciCorp International Corp under the BIOLOGIC SR2 brand and distributed by CCC Chemicals. BIOLOGIC SR2 has been tested and certified non-toxic by a leading toxicity laboratory (Tox Monitor/ BSR Inc., Illinois). The product is certified within the EcoLogo program, North America’s largest, most respected environmental standard and certification mark.
