Product description

EWK Environmental Engineering has been manufacturing systems for the purification of air and waste gases for years.

The SCR (selective catalytic reduction) methods successfullyused for the reduction of pollutants in

Process exhaust air
Combustion gases

The burning of biological fuels, (wood, straw, biogas etc.) as well as fossil fuels (heating oil, natural gas, heavy oil, coal) and industrial waste (solvent, sewage sludge, explosive, refuse and industrial residue etc.) generates large amounts of the following substances even in the most advanced furnaces:

Nitric oxide NOx
Carbon monoxide CO
Hydrocarbons CmHn
Dioxin / Furan PCDD / PCDF

With the SCR catalyser technology these air pollutants can be precipitated to a large degree and converted to N2, CO2, H2O.

Modular construction

The EWK reactors consist of modules set in stainless steel casings with insulation.
This permits an individual assembly depending upon the kind of pollutant and pollutant concentration.
Individual adaption to local requirements.
Compact and economical construction.

SCR catalyzer technology is characterized by:

simple operation
low maintenance effort
long lifetime
high operating safety
low operating costs
easy upgrading of existing systems

Advantages of the SCR-technology with the reaction medium urea

Urea is non-toxic, transportation and storage hold no risks
NOx conversion rates of over 98% are possible
no or negligible reaction by-products
low ammonia slip
