Drinking Water Treatment Facility Ventilation

Drinking Water Treatment Facility Ventilation

Drinking Water Treatment Facility Ventilation

(OP)
Hi. I am working at a drinking water facility. This facility uses membrane filtration, so there is no exposed water anywhere in the facility. A chlorine solution is added towards the end of treatment. This solution is stored in its own room. Like most of these facilities, there are very few and typically one person present. There are no explosion risks or corrosive gasses in the areas of concern. Does anyone know the required ventilation rates for these types of spaces? Thanks.

RE: Drinking Water Treatment Facility Ventilation

I would treat it as a Science Lab. In the 2009 IMC, Table 403.3, it says to exhaust the lab @ 1 CFM/SQ.FT.

Consider cooling ventilation too during the summer, if needed.

RE: Drinking Water Treatment Facility Ventilation

you would need to think of the purpose of your ventilation.

even if there is one-man crew, i would assume there is some cabin for crew presence and that his/her presence in main space is related to specific tasks.

in such scenario i would prefer to calculate acceptable limit for chemicals for both main space and chemicals room (that should have separate ventilation), and ACH approach could possibly be applied to crew cabin only.

this applies only with assumption that your local regulation does not state something different; anyhow, there should be some regulation for upper limit of chemicals concentration, if not directly within ventilation norms, than it would be within medical/sanitary codes.

Thank you all for taking time to answer my question.

RE: Drinking Water Treatment Facility Ventilation

Condensation on the pipes carrying the cold water might be an issue.
Therefore dehumidifying the ventilation air might me required. Or dehumidifying the air inside the room itself.
