Product catalog summary
Introduction
The document provides an overview of Ecochimica's modular panel biofilters, designed for industrial air treatment. These biofilters are used to treat gaseous effluents by metabolizing contaminants through biological oxidation.

Type of Equipment
The biofilter is a modular panel system that uses organic particulate material coated with a biofilm to treat air pollutants. The system is customizable to meet specific client needs, using materials like reinforced concrete, sandwich panels, stainless steel, and aluminum alloy.

Operating Principles
The biofilter operates by allowing air to pass through a bed of organic material, where microorganisms metabolize contaminants into water vapor, carbon dioxide, and biomass. Key operational parameters include maintaining a temperature above 10°C, a neutral pH, and adequate humidity to support the biofilm and microbial population.

System Components
The system includes a biofilter tank, filtration media, modular supports, a humidifier, air inlet, and treated air outlet. A humidifier control panel ensures optimal humidity levels.

Humidity Control
Humidity is maintained using an Ecochimica TW® scrubber/humidifier, which can also serve as a pre-treatment stage to remove harmful contaminants. Alternatively, UHR® series humidifiers can be used for cost-effective air humidification.

Design and Customization
Ecochimica offers custom biofilter designs tailored to client specifications, ensuring efficient air distribution and oxygen circulation through the biofilm. Mixed support materials like compost and bark are used to maintain appropriate porosity.

Technical Improvements
Ecochimica is committed to continuous technical improvements, making the technical data in the catalogue non-binding.

Conclusion
Ecochimica's modular panel biofilters provide an effective solution for industrial air treatment, with customizable options to meet diverse client needs.

IMPIANTI INDUSTRIALI DEPURAZIONE ARIA INDUSTRIAL EQUIPMENT AIR TREATMENT BIOFILTRI BIOFILTERS BIOFILTRO A PARETI MODULARI MODULAR PANEL BIOFILTER TIPOLOGIA DI IMPIANTO: Biofiltro a pareti modulari PRINCIPIO DI FUNZIONAMENTO: Il biofiltro ecochimica® è un impianto di trattamento degli effluenti gassosi. L’aria in ingresso al biofiltro attraversa dal basso verso l’alto il letto/supporto (particelle di materiale organico che, umidificato, si riveste dal “biofilm” acquoso in cui risiedono i microrganismi), metabolizzando gli inquinanti in essa contenuti. Questi vengono trasformati in vapor d’acqua, anidride carbonica e biomassa tramite una reazione di ossidazione biologica con l’ossigeno contenuto nell’aria. Con l’utilizzo di opportuni materiali di supporto organici (compost,cortecce, cippato …) la durata del letto filtrante è dell’ordine di alcuni anni. Una corretta gestione del biofiltro prevede il controllo dei seguenti parametri operativi: temperatura ( >10°C),pH (da mantenere prossima alla neutralità), umidità (per assicurare la permanenza del biofilm e quindi della popolazione microbica) oltre l’apporto di nutrienti e di ossigeno.L’umidificazione si può ottenere mediante scrubber/umidificatore mod. ecochimica TW® che oltre a saturare l’aria in ingresso al biofiltro (condizione ottimale) può essere usato anche come stadio di pretrattamento, allo scopo di bloccare eventuali inquinanti che, raggiunto il biofiltro, potrebbero rivelarsi dannosi per lo stesso. La fornitura di un impianto integrato scrubber–biofiltro in serie, assicura le condizioni desiderate,dato che l'aria in uscita dallo scrubber è satura d'umidità. A tal proposito ecochimica® può fornire umidificatori della serie UHR® meno costosi rispetto agli scrubber TW®, ma altrettanto efficaci allo scopo di umidificare l’aria, meno per un pretrattamente chimico. Infine è indispensabile garantire un’adeguata distribuzione dell’aria in tutto il volume del letto, per facilitare la diffusione dell’ossigeno nel biofilm. L’adozione di un supporto misto, ad esempio compost – corteccia, assicura l’appropriata porosità del mezzo filtrante. TYPE OF EQUIPMENT: Modular Panel Biofilter OPERATING PRINCIPALS: The ecochimica® biofilter is used to treat gaseous effluents. Air entering the biofilter travels upward through the bed/support (organic particulate material coated with an aqueous”biofilm” in which the micro-organisms are present) while the contaminants present in the air are stripped and metabolized. The contaminants are then transformed into water vapour, carbon dioxide and biomass through biological oxidation with the oxygen present in the air. Through the use of appropriate materials (compost, bark, wood chips, etc.) the filter bed can last for several years. Correct operation of the biofilter requires maintaining the following parameters: temperature (>10°C), pH (as close to neutral as possible), humidity (to maintain the biofilm and hence the population of microbes) as well as nutrients and oxygen. The humidity can be maintained through an ecochimica TW® scrubber/humidifier which not only saturates the air entering the biofilter (creating the optimal conditions) but also can be used as a pre-treatment stage to remove any contaminants which could damage the biofilter if they come into contact with it. Using an integrated scrubber-biofilter in series assures ideal operating conditions as air exiting the scrubber is saturated with humidity. For this purpose, where a chemical pre-treatment is not necessary, ecochimica® can supply UHR® series humidifiers which are less expensive than the TW® scrubber but equally effective in humidifying the air. Finally, it is necessary to ensure that the air is distributed evenly through the whole volume of the bed to facilitate the circulation of oxygen through the biofilm. Using a mixed support (for
