5.4 Quarterly Requirements
1. Clean/sanitize the membrane elements. Refer to Section 5.8 for the
membrane cleaning/sanitizing procedure.
Cleaning/sanitizing the machine is vital because contaminants
and/or biological materials accumulate on the membrane surface
potentially reducing the permeate flow rate and affecting the
permeate quality. A layer left on the membrane may cause
permanent damage and reduce membrane life. A decrease in
permeate flow rate, a decrease in salt rejection, or an increased
pressure drop across the machine will indicate when cleaning is
required. Cleaning/sanitizing may be required as often as once per
week or as infrequently as once every two months, depending upon
local water supply conditions.
2. Sanitize the machine. Refer to Section 5.9 for the sanitizing
procedure. Prior to any sanitization, cleaning with Liquid Clean 103
(or equivalent) is required to prevent potential membrane damage.
