Certain industrial processes release biodegradable gaseous compounds that may contribute to unpleasant odours. A Bio Scrubber can be considered where biological treatment is suitable for the contaminants present in the exhaust stream. GPT India, also known as Green Planet Technologies, operates in the industrial environmental equipment sector. System planning requires an understanding of gas composition, flow rate, temperature, moisture, and biological operating conditions. Not every exhaust application is suitable for biological treatment, so analysing the process stream is an important first step. This helps industries compare treatment approaches based on actual operating requirements.
