ventilation fans for sewage treatment

A waste treatment plant is designed for organic and nutrient removal from sewage water, with toxicity traits generally high in the effluents present. Despite many contaminants being extracted as a result of the treatment process itself, there will always be some environmental risks that remain and warrant due consideration.

One of these is the colourless gas hydrogen sulphide – commonly referred to as ‘sewer gas’ – which is highly poisonous, highly corrosive, and often present in wastewater applications. There are various issues associated with hydrogen sulphide, including its threat to human safety, noxious odours given off and the generation of corrosive sulphuric acid.
