Formation and treatment of sewage gas

During wastewater treatment in sewage plants, sewage gas is produced in digester towers through the decomposition of sludge. Sewage gas contains between 45 and 70 vol.% methane, but compared to biogas, it is much more heavily contaminated with pollutants such as volatile organic silicon compounds as well as sulfur and halogen compounds. These contaminants lead to significant wear, increased maintenance efforts, and damage to gas engines or turbines. The characteristic foul smell of sewage gas is due to the high concentration of hydrogen sulfide, which needs to be filtered from the gas mixture.

For the effective and efficient cleaning of sewage gas, we recommend our activated carbon gas filters, as well as our products for gas conditioning and gas drying. Our specifically developed ACO DUO activated carbon filters both sulfur and siloxanes.

Product overview

Gas filtration

Use activated carbon filters to purify your gas of trace contaminants such as H2S, siloxanes, and VOCs. This is an essential requirement for the stable and efficient operation of energy recovery installations.

Our solutions:

Gas conditioning

Directly after exiting the digester or fermentation tank, biogas cannot be purfied or processed downstream in an economically efficient manner. This is because it has the wrong properties and composition, for instance high water content, low gas pressure, is free of oxygen etc. Siloxa offers the necessary technical components for gas conditioning to rectify this. These components can also be combined and delivered as pre-assembled compact modules. These compact gas conditioning systems ensure reliable gas transport through extended pipelines.

Our solutions:

Gas drying

Gas drying removes water vapor from gas, making it a specific form of gas conditioning. Find all information about our cost-effective and efficient gas drying systems for biogas, sewage gas, and landfill gas.

To the safety data sheets

Affordable activated carbon including replacement and disposal

Let SILOXA help you find the optimal activated carbon solution to effectively and efficiently purify biogas, sewage gas, or landfill gas in your facility. We offer a wide range of options, from affordable standard activated carbon to specially developed activated carbon compounds. These high-quality activated carbons can absorb more contaminants and are less prone to self-ignition. Additionally, we provide a complete replacement service where we exchange the old, activated carbon for fresh carbon (either via the plug-in & -out system or on-site) and properly dispose of the spent carbon.

Our activated carbon service includes:

  • Expert advice: Which activated carbon will make your plant operate most efficiently?
  • High-performance or standard activated carbon; we have tailored solutions for every installation.
  • Best prices guarantee: We offer competitive pricing for each quality level.
  • Fast delivery: Whether you choose standard shipping or express delivery, we ensure prompt delivery of your activated carbon.
  • Complete service: We replace activated carbon for all manufacturers' systems and ensure smooth operation.
  • Waste management: let us take care of the proper disposal of your spent carbon.

Good to know

What type of activated carbon do I need for my plant?

Based on a simple gas analysis, we establish the right solution for the efficient operation of your gas plant. Benefit from our experience and obtain a free consultation today!

Why does SILOXA prefer to discuss activated carbon in liters and not in kg?

Our market-leading activated carbon filters, have a maximum filling capacity in liters. To ensure your filter is always at optimal performance, our  high-quality activated carbon is measured and delivered in liters, not kilograms. The same applies for filters supplied by other manufacturers.

Why is high-quality activated carbon so light?

The lower the specific weight of activated carbon (in g/l or kg/m³), the higher the pore volume of the activated carbon. A high pore volume means a lager contact surface, which leads to better purification. High pore volume is a quality characteristic of high-quality activated carbon.
