BW-4040 HYDRON COMMERCIAL MEMBRANES
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, HYDRON recommends removing residual free chlorine by pre treatment prior to membrane exposure. Any specific application must be limited within the extreme operating conditions. We strongly recommend you to refer to the latest edition of technology manual and design guide prepared by HYDRON Membrane Technology or consult experts proficient in membrane technology. In case the customer fails to follow the operating conditions as specified in this manual, HYDRON Membrane Technology will assume no liability for all results. The permeate flow listed in the table is the average value. The permeate flow of single membrane element is within a tolerance not exceeding ±20% of nominal value.
Discard the RO- filtered water produced during the first one hour after system start-up.
During storage time and run time, it is strictly prohibited to dose any chemical medicament that may be harmful.
