Description

Regenerative VOC & Siloxane Removal Systems by ANKA

What is VOC?

Volatile Organic Compounds (VOC) are a class of organic chemicals characterized by their high vapor pressure at ambient conditions. They easily evaporate and are commonly found in waste, industrial processes, and biogas sources such as sewage, industrial waste, and food waste.

What is Siloxane?

Siloxane is a compound found in biogas originating from domestic solid waste, food waste, and wastewater treatment sludge. It is especially caused by wastes originating from cosmetics, food additives, and detergents.

Our Solution

As ANKA, we are proud to have managed to manufacture an industrially viable biogas Regenerative VOC & Siloxane removal system as a result of the R&D studies carried out with the support of the Ministry of Science, Industry, and Technology.

Thanks to its modularity, it can be easily scaled to any capacity with very low pressure loss, which is very important for long-term energy savings. The system consists of two filters containing the filter media used for VOC & Siloxane removal.

These filters work in sequence. When a filter reaches its full adsorption capacity, the system automatically activates the other tank, which is already regenerated and ready. Thus, the gas engines are continuously supplied with clean gas.
