Millenium™ RO System by GE Osmonics 
14693e - 31 Mar 03  4- 22  Routine Maintenance 
4.4.2  Peracetic Acid/Peroxide-Based Compounds (Renalin®) Disinfection 
Procedure 
Renalin®, Minncare™, Peracidin™ and others are trade names for compounds based 
on Peracetic Acid and Hydrogen Peroxide compounds, and are common in dialysis 
facilities. The products referred to in this procedure typically have 20% hydrogen 
peroxide and 4% peroxacetic acid before dilution. Other products are available with 
these same chemicals in different ratios; these are not acceptable for use in the 
Millenium™ RO. Actril™ and other compounds with different combinations of 
these chemicals must not be used on polyamide (thin-film) membranes. The name, 
“Renalin®” will be used in this manual to refer to acceptable products. 
CAUTION: 
New replacement thin film membranes must be rinsed to drain with normal 
pressures for a minimum of three (3) hours before first exposure to Renalin. No 
mandatory pre-rinse of the membranes is required for future disinfections. 
WARNING: 
Follow all Material Safety Data Sheet (MSDS) precautions and OSHA Standards. 
CAUTION: 
‘RENALIN®’ is corrosive to most metals other than stainless steel. The 
Millenium™ uses only compatible materials. ‘RENALIN®’ type products contain 
oxidizing agents and are potentially damaging to thin film (polyamide) membranes.  
It is imperative that all the precautions and instructions are followed correctly.  
Failure to comply with these instructions, which incorporate instructions from the 
membrane manufacturer, will jeopardize the system performance and the warranty. 
Materials Required: 
•  correct amount of disinfectant, per manufacturers’ instructions 
•  2 gallons RO water 
•  clean wide mouth container with volume of 2 ½ gallon or more 
•  product rinse line (clear hose with male QD fitting on one end, open on the other) 
•  “DO NOT USE” warning labels or signs (not provided by Osmonics) 
•  cleaning / disinfect log sheets 
•  most current log sheets for water quality comparison
