Infectious risk effluents

Infectious risk effluents

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.

Departments concerned

Laboratories, morgues, autopsy rooms and dialysis departments.
