The plant is designed for on-site installation in urban hospitals, hospitals lacking connection to sewerage systems and civil water treatment plants. The disinfection system is particularly dedicated to the wastewater of infectious disease wards, operating theatres, ICU and haemodialysis wards. SWT ensures the mechanical treatment and final chemical disinfection of wastewater without producing harmful compounds, thanks to the use of peracetic acid as disinfectant (sodium hypochlorite or chlorine dioxide can be used as well). The plant is completely automatic and does not require continuous supervision. Staff only needs to carry out checks at predefined times and refill the disinfectant tank.
