Waste water and process odors: hybrid odour filter with “extra”

It stinks in here!

With the new COALSI filters, this outrage should be a thing of the past: Fritzmeier Umwelttechnik will be showing at IFAT stand B3.428 how odors from processes and sewage treatment plants can be eliminated up to the olfactory detection limit.

That's right: The odors are not simply retained, but neutralized. This is made possible by the triple hybrid filter developed by Bayern for passive or active ventilation. It is available for street canals, as a pipe insert and as a stationary device for large volumes. Replaceable mat modules form the core element. Each filters physically, chemically, and biologically.

The highlight is the “odor-eating” organisms: They metabolize typical odour generators such as hydrogen sulphide and ammonia. A mat made of activated carbon is responsible for chemical filtering. The porous, fine-pored carbon acts catalytically and thus neutralizes many odorous components. This is where the smaller molecules in particular get stuck. Depending on the application, virtually complete odour retention is possible. If one filter module is not enough, several can be operated serially or in parallel - until no more noses look up. Users confirm the manufacturer's information.

According to Fritzmeier, the gas flow rate is barely affected. The entire surface of the filter mat is flowed through. It is neither a human, plant nor animal pathogen and is therefore harmless to health. Switching is done inexpensively on your own or by the manufacturer.

What many underestimate: Bad odors not only affect employees, residents and nature, but also quickly activate the Environment Agency. Plant and concrete corrosion are further consequences.
