Testoval® Phosphatest® (ortho-Phosphat)

Importance of phosphate monitoring in the brewery

Monitoring phosphate levels is a central component of quality and environmental control in modern breweries. Phosphates occur both as natural components in raw materials such as malt and as technical additives, for example in cleaning agents or water treatment processes. Their careful control is of fundamental importance for several reasons:

1. Product safety and beer quality

Phosphate influences the chemical-physical properties of beer. A balanced phosphate content helps to stabilize the pH value during mashing and fermentation. However, excessive concentrations can lead to undesirable precipitation, changes in taste or turbidity, which impairs the sensory quality of the beer.

2. Process stability

Precise process control is essential in brewing technology. Among other things, phosphates act as buffer substances that regulate the pH value and thus influence enzymatic processes in the brewing process. Fluctuating phosphate values can therefore lead to undesirable process deviations and jeopardize the reproducibility of the end product.

3. Environmental and wastewater relevance

Excessive input of phosphates into brewery wastewater represents a significant environmental problem. Phosphates are the main nutrients for algae and contribute to the eutrophication of water bodies. Strict legal limits therefore apply to the phosphate load in wastewater. Continuous monitoring is necessary in order to comply with environmental regulations and, if necessary, to introduce suitable measures for phosphate elimination, for example through precipitation or biological treatment.

4. Practical monitoring with the Heyl TESTOVAL® phosphate test kit

The Heyl TESTOVAL® phosphate test kit (art. no. 410592) is a reliable, easy-to-use method for phosphate determination for operational monitoring. This manual color comparison kit enables a quick on-site analysis of the ortho-phosphate content in the range of 0-10 mg/l P₂O₅ and is particularly suitable for use in breweries.

Key features:

• Measuring ranges: 0.25 / 0.5 / 1 / 2.5 / 5 / 10 mg/l P₂O₅
• Analysis time: approx. 5 minutes
• 180 determinations per reagent set
• Extension of the measuring range possible through dilution
• Compact and mobile

Application (brief overview):

1. take water sample
2. add reagents according to the enclosed instructions
3. wait for color development
4. compare the result with the color scale and document

The test kit is easy to use and supports close self-monitoring - especially in the field of operational wastewater monitoring and process water analysis.

5. Economic aspects

Targeted phosphate monitoring enables breweries to use raw materials efficiently and optimize cleaning processes. This reduces the use of expensive additives as well as the costs for waste water treatment and environmental charges. Precise control - for example through regular measurements with the TESTOVAL® phosphate test kit - therefore also supports the economic sustainability of the brewery.
