water testing and analysis

Water samples are tested in our laboratory using several methods, depending on the physical and chemical properties to be determined.

We don’t just test for water hardness but also for pH value, Total Dissolved Solids (TDS), Silica, Chloride, Iron, Copper, Manganese and other trace metals. Once the analysis is complete we can recommend the precise type of water filter required to suit your circumstances and equipment being used.

Ask us for a water testing kit to check the quality of water on your site or in your commercial kitchen, return in the free-post envelope and we will provide you with an analysis reporting the make-up of the water and our recommendations for treatment and protection.

temporary hardness

The hardness caused by presence of Calcium and / or
Magnesium Bicarbonates.
For sites with Coffee machines you would typically look
for a Temporary harness of around 80ppm. Check with
your Coffee provider for best results.
For sites with Steam ovens you will need a Temporary
hardness lower than 40ppm.
For sites with Glass washers or Ice machines you will
need a Temporary hardness lower than 20ppm
Determined by titration using dilute Sulphuric Acid and
Bromcresol-Green-Methyl-Red indicator

permanent hardness

Hardness caused by metal sulphates, eg: Magnesium Sulphate and Calcium Sulphate, as well as the only very slightly soluble Calcium and Magnesium Carbonates.

total hardness

The sum of permanent hardness and temporary hardness. Our recommended maximum total hardness is no more than 60 ppm for most premises.
