Anyone with experiences on problems with RO-membranes (clogging) related to water treatment where the chemical used to minimize bacteria changed from hypo-chlorite to mono-amine?
We are running a seawater desalination plant without continous dosing of chemicals to minimize bacteria. When the plant stops we flush the membranes with permeate with a small amount of DNBPA (Biosperse 244). The only continous dosing is sulfuric acid to lower the pH of the seawater.
I’m looking for shared experience with flue gas condensate treatment plants in the following area’s:
– pH in quench, condenser and in the condensate treatment
– CIP of membranes: Frequency and chemicals
– Conservation of UF- and RO-membranes during short time and long time stops
– Lifetime of RO-membranes
Best regards
