DESCRIPTION
Scrubber unitThere is a growing need for innovative solutions to reduce VOC and odour emissions. Odour emissions are not directly harmful to the environment but they are annoying for surrounding areas.Government environmental bodies are increasing their focus on stringent legislation on odour control.The Ecoscrub is specially designed using a combination of various techniques to reduce emissions extensively of the following polluting vapours:- Volatile Organic Compounds- Dust and powders- Polluted steamThe Ecoscrub has a three stage washing facility. The polluted vapour is led to the "HD pipe" where a first washing takes place and where the vapour is cooled down intensively. This provides a maximum extraction of pollution out of the vapour. In the scrubber column two sequential washing operations take place whereas in the last stage the vapour flows through a fiber demister curtain for final treatment. The result is a reduction of up to 80% on Volatile Organic Compound and more than 90% reduction of odour.
