Operating Limits

Feed water

• Dose rate and frequency should be optimized to match the bacteriological challenge of the feedwater.
• For potable applications, refer to local regulations.

Product water

• Not applicable in this context.

Application Methods

Intermittent on-line feed for “shock treatment” control

• Biocide is used only as needed to control fouling.
• Typical starting point for optimization: 200 mg/l for one hour per week.

RO membrane cleaner

• Applied as the first stage of cleaning.
• Concentration: 200-800 mg/l, depending on the degree of fouling.
• Circulate through membranes for 1-3 hours.
• Best added in batches of 200 mg/l four times during the circulation period.
