M-Series Water Purification Machines
1238160 Rev. D 3 - 3 Preparation and Start-Up
3.1 Pretreatment for Water Purification
All systems will operate most efficiently on filtered water with a pH of less than
6.5 and a Silt Density Index (SDI) of 5 or below. If the machine is operated on
higher pH water, other forms of pretreatment may be necessary. A water
analysis prior to start-up of the machine is required. To minimize the chances of
calcium carbonate, calcium sulfate, or other salt precipitation on the membrane,
Mar Cor Purification evaluates each application and water condition and makes
specific recommendations to assure continuity of the membrane sepralator
warranty. Data from the water analysis is processed with a computer program
analysis to determine if potential problems may exist. If the machine is to be run
at a different location than was originally intended, a new water analysis is
required for warranty consideration and should be sent to Mar Cor Purification for
review and recommendations for operation of the machine.
NOTE:
TLC membrane (only) must not contact the following chemicals or
permanent loss of rejection and/or permeate flow may result:
• Free chlorine
• Formalin (until after the RO unit has rinsed to drain for a minimum of
six (6) hours under normal pressures before first exposure to
formaldehyde).
• Iodine compounds
• Quaternary germicides
• Cationic surfactants
• Detergents containing non-ionic surfactants
• Mar Cor Purification cleaners other than those approved for used
CAUTION:
A water softener should not regenerate while the machine is running unless
safeguards are used to be sure the machine is operated on softened water
during regeneration.
