Some of machine manufacturer recommend Total hardness below 100 mg/l and some between 70-600 mg/l like Evaporative Condenser and others 200 mg/l. I totally confused. please make it more clear for me. Many Thanks
What are you using as cleaning chemicals? Nitric acid 68% and NaOH 40-45%
Are the leaks at welds? Are they usually in the bottoms of tubes? the leaks at welds and at the pipe itself and the leaks everywhere bottom, top and sides
Does this plant run at full capacity 24 hrs/day? Yes
What about...
Dear Sirs
We are facing many corrosion in our Stainless steel network pipe and PHE. we are dairy factory, our water from RO. Kindly i am asking the possible reasons for that and what shall we do to stop it.
Thanks
please according to raw water analysis above what do you think the best pretreatment and please what is your recommendation to achieve our final water target with respect Langelier Saturation Index LSI
Thank you
in fact our raw water also contains H2S.
we had blending raw water with permeate before but we stopped that because we face alot of corrosion on network pipe
our water goals:
PH: 7 - 7.5
TH: 8 - 12 degree F
TAC : 8 - 10 degree F
LSI : -0.5 to 0.5
I Hope someone advise me to achieve our goals. please note we use now NaOH and calcium hypochlorite for post treatment
Thank you
May be if we use an anion ion exchange resin on the raw water to use it as blending it will effect on Langelier Saturation Index LSI of product water. please advise
