The application of a novel chemical treatment program to mitigate scaling and fouling in reverse osmosis units

摘要: Abstract The desire for improved chemical treatment programs to mitigate scaling and fouling in reverse osmosis units brought Saudi Aramco Betz International together. challenge produce a program that was simpler, safer, more economical than the traditional sodium hexametaphosphate sulphuric acid identified as mutual goal. This paper presents results of intensive field trials conducted evaluate commercially available formulations. objective any successful antiscalant is address operation's needs well prevent deterioration product water quality or unit production capacity. were based on monitoring conductivity production. Over test period chemical, it recorded there no nor data regressed normalized account fluctuations operating conditions unit. An autopsy second stage membrane by Aramco. found be excellent condition with significant fouling.
