BIOTRICKLING

Product catalog summary
Overview: The document provides technical details about the BIO-TR biotrickling system by Ecochimica, designed for industrial air treatment. It highlights the system's components, operating principles, and advantages over traditional biofilters.
Specifications: The system is constructed with a stainless steel 304 structure and includes components such as a recirculation pump, spray nozzles, a filtering bed, and a recirculation tank. The system is designed to treat gaseous effluents by passing polluted air through a filtration bed composed of siliceous/calcareous materials.
Operating Principles: The biotrickling system operates by allowing air to travel downward through a filtration bed, which is coated with a biofilm containing microorganisms. These microorganisms metabolize contaminants through biological oxidation, converting them into water vapor, carbon dioxide, and biomass. Proper air distribution and temperature control are essential for efficient operation.
Advantages: Compared to biofilters, the biotrickling system is a closed system that offers higher efficiency and requires less installation space. It is designed to be customized according to the specific needs of each customer.
Design and Customization: Ecochimica offers custom-designed systems to meet unique customer requirements. The company is committed to continuous technical improvement, making the technical data in the catalog non-binding.

IMPIANTI INDUSTRIALI INDUSTRIAL DEPURAZIONE ARIA TIPOLOGIA DI IMPIANTO: Biotrickling Sistema di umidificazione Humidification system Struttura in acciaio inox Aisi 304 Stainless steel 304 structure Ugelli di spruzzo Spray nozzles Ingresso aria da depurare Polluted air inlet PRINCIPIO DI FUNZIONAMENTO: Il biotrickling ecochimica® è un impianto di trattamento degli effluenti gassosi. L’aria in ingresso al biotrickling attraversa dall’alto verso il basso il letto filtrante, composto da materiale siliceo/calcareo (lapilli, gusci di mitili, ecc.) che ha una durata di alcuni anni. Questa materiale, umidificato e quindi in ambiente acquoso, si riveste dal “biofilm” in cui risiedono i microrganismi che metabolizzano 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. Deve quindi essere garantita un’adeguata distribuzione dell’aria in tutto il volume del letto per facilitare la diffusione dell’ossigeno nel biofilm. Una corretta gestione del biotrickling prevede inoltre il controllo della temperatura e l’apporto degli opportuni nutrienti. Rispetto al biofiltro il biotrickling è un sistema chiuso, più efficiente, che richiede minor spazio in pianta.

Air enters the biotrickler and travels downward through the filtration bed, which is composed of siliceous/calcareous material (lapilli, mollusck shells etc.) and can last for several years. This material, humidified within the biotrickler, is coated with an aqueous ”biofilm” that houses the micro-organisms which metabolize the contaminants present in the air (through biological oxidation), transforming them into water vapour, carbon dioxide and biomass. Thus there has to be an even distribution of air throughout the whole bed volume, to facilitate the circulation of oxygen throughout the biofilm. Correct operation of the biotrickler requires the maintenance of the temperature, as well feeding soluction. Compared to the biofilter, Biotrickling is a closed system with higher efficiency and re
