In a first tank, a disinfectant buffer solution (base) is injected to ensure the disinfection of the effluent as it arrives. After the contact time has been allowed, the disinfected effluents are transferred, by a lift pump, to a second tank.
In this tank, a pH test is performed, followed by the proportional injection of a neutralizing agent (acid). Mixing is put into action and another pH check is run before an authorization is given to release the effluent into the drain network.
