INDION 8100 Cleaner Technical Data Sheet
GENERAL

INDION 8100 Cleaner is intended for use in removing calcium sulfate, barium sulfate, and strontium sulfate scales from RO membranes. INDION 8100 Cleaner is also effective in removlng biofoulants, organics, and metal oxides/hydroxides.

DESCRIPTION AND TYPICAL PROPERTIES

INDION 8100 Cleaner is a proprietary blended product supplied as a fine powder and has the following properties:

Form/Appearance White powder
Bulk Density (lb/ft3 ) 62
pH of a 2% Solution in Water 11
USE CONSIDERATION

We recommend using a 2% INDION 8100 Cleaner solution (1 lb product per 6 gal water) for removing deposits from RO membranes. The required volume of cleaning solution and product quantity can be estimated using the mix rate above and Table 1. INDION 8100 Cleaner is suitable for cleaning most RO membranes although the pH should be adjusted for use on CA membranes.


PACKAGING

INDION 8100 Cleaner is suppiied in 40 lb (net) plastic bags packaged inside cardboard boxes (12" x 12" x 9" ) with cardboard liners.

NOTE A : Estimate of the high total flow (HTF) or medium total flow (MTF), expressed in gpm, to the section to be treated when there are multiple pressure vessels in parallel:

HTF = #U x HF (or) MTF = #U x MF       Equation 1

Where

  •   #U is the number of vessels in parallel.
     
  •   HF or MF are the high flow or medium flow per vessel from Table 1 above for
      the appropriate RO/UF DIAMETER.

       

      



    NOTE B : Estimate of the cleaning solution volume (V) expressed in gallons:

    V = #M x VOL x 5                            Equation 2

    Where

  •   #M is the number of elements.

     
  •   VOL is the VOLUME of one element from Table 1 above for the appropriate
      RO/UF DIAMETER.

       



    NOTE C : Estimate of the INDION Cleaner quantity (Q) required expressed in pounds:

    Q = V x MR x 8.34                           Equation 3

    Where

  •   V is the cleaning solution volume defined in Equation 2 above.

     
  •   MR is the cleaner mix ratio as defined on the front side of this bulletin.




    NOTE D : Estimate of flush time (t) expressed in minutes:

    t = (#EL x VOL)/HTF                           Equation 4

    Where

  •   #EL is the number of elements/permeators.

     
  •   VOL as defined in NOTE B above.

     
  •   HTF as defined in NOTE A above.
