AAT Abwasser- und Abfalltechnik GmbH products

AAT microbial desulphurization is used to reduce hydrogen sulphide in biogas, WWTP and landfill plants on an ecological basis. Apart from methane and carbon dioxide, toxic hydrogen sulphide is produced in fermentation process as well. This acts corrosively on the consumers and equipment.

The AAT air pump ensures the dosage of the air requiered for the deluphurisation in the gas chamber of the digester. During the fermentering process in biogas plants, tho course of the anerobic degradation of organic substances creates toxic hydrogen sulphide. Blowing in air causes the micro-organisms to oxidise the hydrogen sulphide zo elementary sulphur and sulphate. For this reason, air dosage is an especially easy and yet very effective and economical method of desulphurization. The air pump used has been designet for continuours operation and is thus especially long-lasting.
