Bromine injection - incoming drinking water line
Bromine injection - incoming drinking water line
(OP)
I've been asked to source a bromine injection unit for an incoming 3" drinking water line for one of our ships. This is outside my field, and I can't seem to find a suitable unit on the internet.
Any leads/suggestions?
Thanks a lot,

Wasn't put into soldiers' tea during the war? To suppress certain urges?
Cheers,

It was the Superintendent of the Project who asked me to source the unit, because bromine apparently does a good job of disinfection, but doesn't create as many problems with corrosion.

PVDF lines with PVDF Watson-Marlow pump will do the job.

It used to be rumoured that the British Army put bromine/bromide into soldiers' tea during WW2. Have no idea if it's true, but the soldiers' suspicion was that it was meant to make the monastic life easier to bare.
Should you be choosing the disenfectant on the basis of protecting equipment? Shouldn't it be on the basis of providing the best, safest drinking water to personnel? (I wouldn't tell 'em about the supposed side-effects!)
Cheers,
John.

Another alternative could be hydrogen peroxide but check the dosage first

If you mean to dose liquid bromine usually a chemical metering pump be best. You need to know how much you wish to inject, the strength of your bromine, the pressure in your water line and what flow rate of water you need to dose (flow proportional or ORP/Redox dosing control may be suitable). Is it for ship storage tank top up? You could talk to the local representative for Dosapro Milton Roy pumps www.miltonroypumps.co.uk Telephone 44(0)11 89 77 10 66
Bromine liquid can be very agressive and gaseous and normally needs PVDF wetted parts and degassing valves.

I am tracking down where the directive came from originally within our organisation as to the use of bromine, as well as continuing to follow-up on the leads you've provided.
- HudCameron - the unit would be used to initially fill the main fresh water tanks, and then keep filling them as necessary during port times. The ship is to be used as a hospital in West Africa for up to 8 months at a time, so fresh water would be taken onboard locally during those times. We're looking into the feasibility of generating fresh water in a West African port, but it doesn't look very promising at the moment.
