To ensure accurate membrane product selection and performance prediction, customers should conduct at least one comprehensive chemical analysis of the feed water. Ideally, multiple analyses should be performed over an extended period or during potential abrupt changes in water quality. Historical trends in membrane system performance parameters are crucial, particularly for surface water sources, which may exhibit seasonal variations due to spring runoff or lake/pond turnover events. Frequent changes, such as heavy rainfall or even wind—which can stir up sediments in lakes or ponds—affect surface water composition and lead to fluctuations in feed turbidity. Generally, the more existing and historical data analyzed, the better the overall system design.
For example:
Surface water may contain suspended solids, organic matter, and various microorganisms;
Well water might include scaling substances such as hardness and silica;
Municipal water sourced from surface supplies could contain residual chemicals from treatment processes, including aluminum and iron, which may deposit on membranes in the form of hydroxides or silicates;
Recycled industrial wastewater may introduce various contaminants, scaling components, and membrane-damaging compounds such as oils, surfactants, and defoamers.

Notes:
a. The maximum temperature for continuous operation at pH above 10
is 95 °F (35 °C).
b. Under certain conditions, free chlorine and other oxidizing
agents may cause premature membrane failure. Since damage from
oxidation is not covered under warranty, it is recommended that
customers remove residual chlorine through pretreatment prior to
membrane contact.
