Coffee Water Quality: Hardness, Alkalinity and Chlorine
Hardness
Calcium and magnesium influence extraction and scale.
Alkalinity
Buffering capacity affects acidity and scale behaviour.
Chlorine
Can introduce unwanted taste and odour.
What to consider
- pH and alkalinity
- Hardness
- Chlorine
- TDS and sediment
Selection questions
What water information should I send for a coffee filtration enquiry?
Send a current water report covering hardness, alkalinity, chlorine and TDS where available, together with the coffee equipment model and estimated daily demand.
Should water treatment be selected from TDS alone?
Use TDS alongside the other water parameters and the equipment requirements listed on this page. Share the complete available report so the application can be reviewed.
Prepare a water report for coffee equipment
Include hardness, alkalinity, chlorine and TDS results where available, together with the equipment model, daily demand and service interval target. These details make a coffee water treatment enquiry more useful than a single water-quality reading. Use the equipment requirements and proposed cartridge documentation when reviewing a configuration.
Need application-specific guidance?
Share your water report, equipment, volume and target market with our team.
Keep units and equipment requirements with the water report
Send the report date, sampling point and units alongside hardness, alkalinity, chlorine and TDS results where available. Describe any storage or treatment already between the supply and the machine, and include the equipment’s inlet-water specification.
These details help compare a proposed configuration consistently. Prepare a selection brief and identify the coffee installation before requesting a cartridge or system proposal.
