Inlet Cutting Water Requirements
The inlet water should have a pH of
6
to
8
and be clear, odorless, and free of biological materials.
The water quality should be analyzed to insure the incoming water will not have and adverse affect on
the waterjet system.
The water quality analysis should measure for:
•
pH
•
Silica Content
•
Total Dissolved Solids (TDS)
Most systems just need water softening to pre-treat the inlet cutting water. Poor water quality may
require other types of treatments to remove the high levels of TDS. One approach is to have the local
water conditioning company provide de-ionizing (DI) tanks on an exchange basis, or install a reverse
osmosis (RO) system. The RO approach is best for high gallon-per-day users.
Water Treatment Guidelines:
High Quality Water
TDS < 50 ppm
No treatment required
Good Quality Water
50 ppm < TDS < 150 ppm
Soften only
Medium Quality
Water
150 ppm < TDS < 250 ppm
Soften or TDS removal
Poor Quality Water
TDS > 250 ppm
Silica > 15 ppm
TDS removal
NOTE:
Do not treat to 0.5 ppm or less: Water of this high of purity is overly aggressive and will
damage stainless steel components.
