Waste Water Treatment Plant

In sludge treatment units, sludge treatment units and biological treatment sections of wastewater treatment plants, the generally predominant odors are sulfur and nitrogen-containing. These can be listed as H₂S, methyl mercaptane, dimethyl sulfide, ammonia, trimethyl amine fatty acid odors and aldehydes.

• Cleaning odor components formed as a result of biological processes in wastewater treatment plants
• Reduce chemical consumption and provide a design that can be applied even in facilities with limited area.
• To provide efficient operation of biological treatment processes in the aeration units
• Used to achieve energy and operational efficiency.

Biogas Purification System

Biogas has emerged as a notable renewable energy source, playing a substantial role in the reduction of greenhouse gas emissions and the support of a sustainable energy future. However, the raw form of biogas frequently contains impurities that can limit its application and compromise equipment performance. Among these impurities, hydrogen sulfide (H₂S) poses a substantial problem due to its corrosive nature and the potential for environmental degradation.

Biological scrubbers use microorganisms to oxidize H₂S to elemental sulfur or sulfate. This method is environmentally friendly and cost-effective in the long process as it avoids the use of chemical reagents. Biological scrubbers are particularly suitable for large-scale biogas plants with a continuous H₂S. However, they require careful monitoring and control of environmental conditions such as temperature and pH to maintain microbial activity.

Clean biogas contains more methane, increasing combustion efficiency and energy output. For biogas plant operators, this improvement translates directly into improved performance and lower operating costs.

Geothermal Energy Power Plant

Geothermal power plants use hot water and water vapor from the ground to generate energy. However, these geothermal fluids are not just water and vapor; they can contain dissolved gases such as H₂S, mercaptans, and to a lower extent, CO₂.

These gases can be cleaned using bioscubbers, which is a more environmentally friendly approach than chemical scrubbing and thermal oxidation systems.

However, the temperature of the dirty gas coming from geothermal plants is extremely high. In order for the microorganisms to survive in the bioscrubber scrubbing system, this temperature is first reduced below 40°C using a condenser.

H₂S gas can be cleaned biologically with 95-99% efficiency without producing chemical waste.

Chemical and Petrochemical Industries

Both industries involve processes that release H2S, ammonia, VOCs and other harmful gases. These gases must be cleaned in accordance with established environmental and safety standards. The use of bioscrubbers can provide a more sustainable and economical solution for cleaning these pollutants. The types of pollutant gases released by industries are generally as follows.

• Crude Oil Refining, Gas Processing, Sulfur Recovery Units

Hydrogen Sulfide (H₂S)

• Solvent Based Manufacturing, Polymerization Processes

Volatile Organic Compounds (VOCs)

• Storage Tanks, Filling Systems

Gasoline Vapors (Hydrocarbon Derivatives)

• Plastics, Fertilizer and Synthetic Fiber Production

Ammonia (NH₃)

• Oil Refineries, Gas Processing Plants

Mercaptans (R-SH)

Similar to other sectors, the temperature of the system to be used in the bioscrubber should be brought to the optimum living conditions of the bacteria. Then the bacteria are selected according to the type of pollutant, and the cleaning process is carried out.

The use of bioscrubber in these sectors is preferred due to its advantages, such as low cost, low chemical consumption and multiple pollutant removal at the same time.

Food and Beverage Industry

In the food industry, odors are caused by a variety of conditions, including raw material processing and process reactions. Microbial decomposition of organic compounds, often in waste or wastewater treatment plants in the food industry, can also produce a variety of odors.

• Dairy Industry

Organic fatty acid odors from fermentation in cheese, yogurt, butter, and powdered milk production.

• Meat and Fish Rendering Plants

Ammonia and organic sulfur compounds

• Brewery Industry

VOCs, NH₃, H₂S, and aromatic compounds are released during the production of fermentation products such as beer and wine, as well as from by-product storage tanks, silos, and wastewater treatment.

• Coffee Roasting and Flavoring Plants

Bioscrubbers are used to remove phenols and aldehydes released in coffee roasting and flavoring plants.
