Cleaning and Chemical Exposure Guidelines

• Adherence to cleaning and sanitizing procedures (chemical concentrations, pH, temperature, and exposure time) is necessary for maximum element life. Accurate records must be maintained.
• KMS standard cleaning procedures for dairy applications should be followed.
• Recommended chlorine exposure time: 30 minutes per day.
• Residual chlorine concentration during CIP should be 150 ppm @ pH 10.5-11.0.
• Chlorine concentration should never exceed 200 ppm.
• Chlorine should only be added to the cleaning solution after the pH has been adjusted to 10.5-11.0.
• Iron or other catalyzing metals in the presence of free chlorine or hydrogen peroxide will accelerate membrane degradation.
• Sanitizing should be done only after a complete cleaning cycle and with water of acceptable quality.
• Cationic Polymers and Surfactants: Dairy-Pro® UF membranes may be irreversibly fouled if exposed to cationic (positively charged) polymers or surfactants. Exposure to these chemicals during operation or cleaning is not recommended and will void the warranty.
• Lubricants: For element installation, use only water or glycerin to lubricate seals. The use of petroleum or vegetable-based oils or solvents may damage the element and will void the warranty.
