A synthetic biofilter media for ammonia (NH3) removal
In this work, a patented biofilter media is used in treating air contaminated with ammonia (NH3). The data shows up to 200 ppm of NH3 can be removed with over 93% removal efficiency at 30 s Empty Bed Residence Time (EBRT). At the start–up conditions, the results also indicated that the humidifier can be utilised for buffering concentration fluctuations. The design correlation developed based on ...

Biofiltration Treatment of α-Pinene
This paper provides an overview of air biofiltration with experimental data on the performance of a synthetic media biofilter system. It is shown that use of high surface area per unit volume structured media results in higher contaminant treatment rates per unit biofilter volume. It is shown that use of specially designed synthetic media allows effective control of biomass buildup by continuous ...

Reduction of odor and odorant emissions from slurry stores by means of straw covers
Swine (Sus scrofa) slurry stored in open storages is a source of airborne contaminants. A customary practice for ammonia and odor control consists of covering the surface of the slurry with floating materials, such as straw. Although straw covers have been proven to generally reduce gaseous emissions, more knowledge is needed regarding how age, moisture content, and microbiological development of ...

Biofilters vs Asdorption
In the last three decades biological technologies have emerged as a sustainable and economically-viable alternative compared to traditional techniques like adsorption/absorption for purifying gases. They were well-received initially in the industry and interesting products with good results were carried out for several years. However, owing to a series of reasons that will be detailed in this ...

Biofiltration: An Innovative Technology for The Future
Biofiltration refers to the biological transformation or treatment of contaminants present in the gas phase, usually air. The fact that air contaminants can be biodegraded by active bacteria has been known for quite some time. However, it is only in the last 10 years, that biofiltration has begun to emerge as an economically viable treatment process. Initially, biofiltration involved the use of ...

Case study - Styrene emissions: Catalytic oxidizer with concentrator
Overview The world's largest button manufacturer needed a pollution control system that would destroy styrene emissions from a variety of plant processes. The plant was proactively seeking a cost-effective air pollution control solution to preempt future regulatory action. The main concern of the customer was the high operating cost of an emission control system. Action After thorough ...
