The project involves supplying and installing a treatment unit designed to treat and neutralise wastewater from the mortuary. The process used will be chemical, based on the action of sodium hydroxide NaOH. It is imperative that all effluent from the autopsy room and, in principle, from all points where liquid discharges are likely to be contaminated, particularly with ATNC, be treated. These discharges are loaded with organic matter. In accordance with DGS/DH directive No. 138, CNTs will be inactivated in a treatment unit.
The process used will be chemical, based on the principle of the action of sodium hydroxide (NAOH). To ensure the neutralisation of the effluent and in particular the inactivation of ATNCs, in accordance with legislation, the contact time will be at least 1 hour at pH 12.2, then the chemically active effluent will be neutralised with acid to bring the pH down to between 6.5 and 7.5 so that it can be discharged into the urban network. All the effluent from the technical room will be stored in the treatment unit during the day so that it can be neutralised in the evening.
