Effluent Treatment Plant

Effluent Treatment Plant
The effluents from the experimental area as well as the rearing areas harboring transgenic animals (anti-exhaust system) are collected and treated by chlorination.
Plan Do Act Check

Both showers are fitted with a lifting pump (type vacuum cellar) which allows to evacuate these effluents towards a storage tank of a capacity 6 m3 located under the technical awning.
The disinfectant (sodium hypochlorite) and the neutralizer (bisulphite of soda) are stored in two 125L tanks located at the storage tank
- The effluents from the treatment tank are mixed by means of a mixing pump
- During mixing, an injection of disinfectant (sodium hypochlorite at 48 ° chlorometric) is done by a dosing pump set to 1/1000 (1L of disinfectant per 1 m3 of treated water). Bibliography P. De Kinkelin
- A contact time of 15 min is achieved.
- At the end of this contact time, the brewing pump stops
- Another injection of chlorine neutralizer (Bisulfite of soda) is also done by a metering pump in order to stabilize the pH to 7
- The brewing pump turns on
- A contact time of 5 min is achieved
- The brewing pump stops
- At the end of the cycle, a solenoid valve opens to empty the treatment tank into the central wastewater system

Elle repose sur le principe d’amélioration continue de la performance environnementale par la maîtrise des impacts liés à l’activité de l’entreprise. Cette démarche est souvent représentée par la roue de Deming :

    iso14001 est la dénomination d’une norme qui concerne le management environnemental et dont les caractères sont propres à rassurer les consommateurs soucieux de l’environnement. Elle est une partie intégrante des normes d’organisation et l’ISO ou Organisation Internationale de la Normalisation (International Organisation for Standardization) en est l’organisme créateur.

It is an integral part of organizational standards and the ISO or the International Organization for Standardization is the creative organization.
