BIOWENT® - air purification system

 
The BIOWENT®- air purification system has been designed for removal of air volatile contaminants discharged from municipal and industrial plants. Reduction of organic and inorganic compounds, such as NH3, H2S, mercaptanes, amines, aldehydes, ketones, organic acids etc. is possible due to application of proper filtration bed. The above mentioned compounds are typical odours emitted from waste water treatment plant structures and appliances, pumping stations, food processing industry, paint shops and foundries etc. The application of BIOWENT® system eliminates unpleasant emission of contaminants, which in practice means improvement of the environment.
 
 

Operating principles

In the biological process of air purification odours are removed by means of specialized micro-organisms immobilised into a natural bed. Such factors as the proper bed structure, correctly chosen micro-organisms, size of appliances, humidity and temperature influence on the process. The efficiency of biofiltration mainly depends on the biofilter load. Correct biofilter designing leads to nearly 100% odour reduction. Every 3-5 years, it is necessary to regenerate or exchange the biofilter bed. The old used up material poses no threat to the environment because it could be composted and then used directly as natural fertilizer.

 

Structure

The air purification system BIOWENT® consists of a fan, a moistener and a biofilter. Contaminated air is forced by a fan through a moistener where it reaches the necessary moisture content. Then the air passes through a biofilter containing selected micro-organisms where pollutants are absorbed and undergo biodegradation. The purified air is discharged to the atmosphere. The biofilter housing is made of GRP which provides good strength, corrosion resistance and an aesthetic outlook.

The purification process parameters are controlled automatically which decreases operational costs significantly. The system is equipped with alarm detecting and informs about possible anomalies. Optionally alarm signals can be transmitted to a remote operator by radio or phone lines. The biofilter size depends on the air flow and concentration of pollutants and is dimensioned so that full reduction of odour components can be achieved. Biofilters can be extended during operation by adding modules.
