The Bio-T (Biotrickling) is a system that causes the bacteria to be immobilised on an inert media allowing the system to treat high levels of H2S without suffering decomposition of the media.

The Differences Between Bio-F & Bio-T

Unlike a biofilter, where the acidic by-product is neutralised in the bed by reacting with an alkaline agent added to the blend, a biotrickling filter is intermittently flushed with nutrient rich water, that washes away some of the by-products and flushes it to the drain.

As such the drain liquor in a biotrickling filter often has a pH in the range of 1-2 vs. a range of 6.5-7.5 in a biofilter. Lo pH in a biotrickling filter is a good indicator that a healthy population of bacteria exist and that H2S is being treated.

Applications

Suitable for medium to high air flows (1,500 - 18,000m3/hr) and high H2S concentrations (10-100ppm average/50-1000ppm peak concentrations), the BIO-T biotrickling filter.

Well suited to pump station and larger wastewater treatment plant applications, (Note: Larger flows can be treated by configuring the process units in parallel).

Features

The BIO-T biotrickling filter is based on the principal of immobilised fixed film microbiological technology where-by select bacteria are able to utilise contaminants in the air stream as a part of their energy pathway.

A combination of Diffusion, Disassociation and Oxidation result in H2S being converted to Sulphate and Hydrogen.

Also differentiating the two technologies is the need to add nutrients to the intermittently sprayed water that trickles down over the packed beds, providing the bacteria with the required nitrogen and phosphorus needed to maintain a healthy population.
