• Maximum temperature for continuous operation above pH 10 is 95°F (35°C)).
• Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, Dow Water & Process Solutions recommends removing residual free chlorine by pretreatment prior to membrane exposure. Please refer to technical bulletin “Dechlorinating Feedwater” for more information.
