VIII. MAINTENANCE OF “TMR090 SERIES”
1. Maintenance Items and Maintenance Frequency
To maintain the performance of “TMR090 Series”, perform the following at specified
intervals:
(1) Clean the air diffusers (when extraordinary uneven diffusion is found).
(2) Chemical cleaning of the element (when the trans-membrane pressure has risen
by 5 kPa (50 mbar) or more from its initial operating level at the same permeated
water flow rate or every 6 months, whichever comes first).
(3)
Replace connection tubes (once in 3 years, or when deteriorated)
(4) Replace element comb gaskets (once in 3 years or when deteriorated, whichever
comes first).
(5) Replace elements (when the specified treatment flow rate is not gained even after
chemical cleaning or when deteriorated, whichever comes first).
(6) Replace air diffusers (once in 3 years or when extraordinary uneven diffusion is
detected even after cleaning, whichever comes first).
Be sure to use the specified types of the replacement parts.
Please contact TORAY for the detailed specifications and the
procurement routes for replacement parts
Insert the tube securely into the foot of the nozzle when replacing
the tube.
Don't apply excess force to the element and manifold nozzles to
prevent damage when replacing permeate tubes or elements.,
Don’t re-use the old permeate tubes once disconnected from the
nozzles since the connection tightness of the tubes are reduced.
Be careful not to scratch the membrane surface during element
replacement works.
