Ammonia  –  NH₃ 

Released ammonia spreads into the air, reacts with other air pollutants and forms particulate matter. Ammonia itself and the particulate matter formed in the air endanger human health and damage plants and ecosystems.

Ammonia spreads through the atmosphere, is transported, and is deposited in ecosystems, where it can then cause over-fertilization. In addition, ammoinia contributes to soil acidification.

Ammonia can lead to changes in the species composition of biotic communities and to the death of individual species.

Ammonia occurs in the exhaust air from wastewater treatment plants, particularly during sewage sludge drying.

Agriculture is the main source of ammonia emissions in Germany, accounting for around 95 percent. Other emissions come from industry, the energy sector and waste management.

Ammonia escapes mainly from manure and slurry applied to agricultural land. Other sources of ammonia include mineral-based percolating fertilizers, fermentation residues from biogas production, and the excretions of grazing animals.

The TA-Luft provides for an ammonia limit value of 150 g/h in the mass flow.

The mass concentration must not exceed an ammonia value of 30 mg/m³.

We neutralize ammonia in the exhaust air with UV ozone technology. The ozone is generated in an environmentally friendly way via UV light.

If necessary, a column scrubber can be connected upstream to separate ammonia.

Harmful substances are split into water and carbon dioxide.

Depending on the requirements and design, the cleaning effect of the plants is bi2 95%, with a catalyst even 99.9%.

• Very effective
• Little space required
• Much lower energy consumption than thermal processes
• Very low maintenance
