Dears please why always we should add caustic soda solution be diluted to water not vice versa? Thank you

Dear EdStainless, Can you please send me a manual explain this point and the relation between water quality and corrosion Thank you

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

Thank you bimr for your reply Please what is alternative of NSF (Europe) Thank you again

So please what is the maximum values of TH to avoid scaling Thank you

Can you please provide me the specification Thank you

Please I would like to know the limiting values of water total hardness that use for 316L Stainless Steel Heat Exchangers? many thanks.

Please what is the specification of Hydrochloric Acid to be use for potable water (Food Grade)? Thank you

Please What are the most important water parameters to monitor and its limits ?

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...

what is suitable water characteristics for Stainless steel 316 and 304 to avoid corrosion

Stainless steel 316 and 304 the problem that we are facing always there is leak in the pipe and PHE

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 What is the procedure for cleaning RO membranes? And which one should always be performed first The high pH cleaning Or The low pH? Thank you

please be informed we do not inject Chlorine for oxidation we use compressed air

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

Thank you bimr for your reply It's potable water application. please find below our well water analysis: ASPECT Limpide Turbidité NTU 10.00 Température °C 43.60 Conductivité µs/cm 6,270.00 TDS mg/l 4,702.50 pH 7.01 TH °F 120.00 Ca++ °F 95.00 Mg++ °F 25.00 TA °F 0.00 TAC...

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
