classic case
System process:
Lake water → mechanically accelerated sedimentation tank → raw water tank → sand filter → ultrafiltration → intermediate water tank → reverse osmosis → decarburization → clean water tank → ion exchange (anion, cation bed, mixed bed) → demineralized water for boiler
System scale:
≧65T/H (25℃ water temperature)×2 groups
system issue:
The water production of the system drops rapidly in a short time, and the cleaning cycle is shortened to 2 months
problem found:
Severe mechanical fouling and colloidal pollution were found on the membrane inlet end cap and reverse osmosis membrane surface
solution:
By off-line cleaning and adjustment and optimization of the system, the cleaning cycle of reverse osmosis can be extended to 1 year!
