Health and Safety assessment.

Treatment of wastewater may pose risks to the health of WWT operators since wastewater is a rich substrate for several bacterial, fungal, viruses and contains a range of chemicals depending on the nature of the sewage. Wastewater treatment systems are moreover becoming increasingly important for the treatment and dispersal of the effluents. The aim here is to assess the potential risk associated with WWT with focus on the occupational exposure assessment in line with the risk assessment paradigm (Hazard identification, Dose-response assessment, Exposure assessment, Risk Characterization). Risk assessment will be estimated by applying modelling approach (e.g. online control banding and risk management tool) and using criteria of severity and probability of accident.The assessment of health and safety aspects will encompass the identification of all major internal and external health and safety factors that influence or potentially have impacts on the application of the new technologies in WWT.
