Performance Data
Test Parameters: Temperature, Pressure, Turbidity, TDS, and pH analyses were conducted at WQA’s Performance
Laboratory. Chlorine free deionized water was used which has a conductivity of less than or equal to 1μS/cm.
Sodium chloride (NaCl) was then added to the test water to achieve a TDS challenge concentration within range.
The following conditioning was performed with water: 1-hour ush, 10-hour soak, 1-hour ush, 12-hour soak,
1-hour ush, 7.5-hour soak, then 5 to 10-minute ush. No samples are collected during the 54-hour stagnation
period covering days 5 and 6. Analysis was performed at WQA.

Factors Affecting Reverse Osmosis Performance
Permeate *ux and salt rejection are the key performance parameters of a reverse osmosis or a nanoltration
process. Under specic reference conditions, ux and rejection are intrinsic properties of membrane performance.
The ux and rejection of a membrane system are mainly inuenced by variable parameters including:
• pressure
• temperature
• recovery
• feedwater salt concentration
*mL is the number of particles per milliliter.
*The National Primary Drinking Water Regulations (NPDWR) are legally enforceable primary standards and treatment techniques that apply to public water systems. Primary standards and
treatment techniques protect public health by limiting the levels of contaminants in drinking water. For a complete list of regulated contaminants, please visit
