Ideal mineral ranges for coffee extraction.
| Parameter | Target | Acceptable Range |
|---|---|---|
| TDS | 150 ppm | 75–250 ppm |
| Hardness (CaCO₃) | 68 ppm | 17–85 ppm |
| Alkalinity | 40 ppm | ≈40 ppm (HCO₃) |
| pH | 7.0 | 6.5–7.5 |
Reverse osmosis plus mineral addition gives more control than trying to filter hard tap water.
Mix 5 L test batches before scaling to 20 L café reservoir — errors are costly at volume.
Wear gloves when handling concentrated mineral solutions — avoid skin contact and eye splash.
Crucial code requirements, material risk alerts, and prevention checklists for Water Chemistry Optimization Guide.
⚠️ Risk Warning: Purchasing net calculated material causes project delays when cuts or breakage occur.
💡 Prevention Action: Always add a 10%-15% buffer allowance to initial calculated quantities.
⚠️ Risk Warning: Applying finishes to dusty or uneven surfaces reduces adhesion by up to 60%.
💡 Prevention Action: Vacuum, prime, and check levelness (max 1/8" gap over 10 ft) before starting.
