Process Of Water Purification - LG WAW73JW2RP Owner's And Operator's Manual

Process of water purification

Notice
The filter is a vital part of the water purifier. If authentic filter is not used, or old filter
is used even if it is an authentic one, such can cause performance deterioration.
Process of Purification
Drinking water
Step 1: Out Sediment filter
Remove large visible impurities as
well as finer suspended particles such
as dirt and sand from the water.
Step 2: Sediment filter
This protects the part (or place) with
which water comes in contact by
filtering unseen dust and contaminated
substances.
Step 3: Pre-carbon filter
The remaining chlorine and volatile
organic compound are removed at
this pre-carbon filter.
Step 4: RO membrane filter
Heavy metallic substances, ionized
substances, and microorganism are
removed through this membrane filter.
At this step, drained water comes
1)
out through the drain hose.
Step 5: Post-carbon filter
The remaining smell in the water is
filtered at this step, and the taste of
water is improved.
