Is it worth measuring sludge levels in primary treatment?

Measuring sludge level, reduction in volume and cost reductions.
More about sludge levels

TOC wastewater analysis

TOC has steadily gained in importance in wastewater analysis. In relationship to COD in particular, it provides specific information about the type and origin of organic loads in wastewater.

LDO = 80% less maintenance in the paper industry

In Europe’s biggest factory for sanitary paper products, belonging to Procter & Gamble, the optical O2 sensor regulates the aeration. The maintenance requirement has been reduced by 80%.

More about maintenance reductions


Increased efficiency in biogas production

Reliable process and laboratory analysis result in stable fermentation processes and economic plant operation.

More about biogas production



Measurement of COD in landfill leachate saves money

Optimised refilling of the activated carbon filters of a biological treatment plant with the help of COD measurement: annual savings of 25,000 €.

Easy and reliable analysis of heavy metals

Interference ions, colours, turbidity and complexing agents can make the analysis of heavy metals problematic. We found the solution for you.

More about heavy metals



Quality assurance in laboratory & process

The quality of the measurement results depends crucially on the care taken during the individual work steps and the quality assurance procedures that are in place. HACH LANGE explains important AQA steps in a practice report.

Water quality monitoring 40 metres below the sea bed

Natural groundwater collected around the tunnels operated by Eurotunnel is continuously monitored before being pumped to the coast and discharged into the sea. Six multiparameter water quality monitoring systems have been custom-designed by HACH LANGE to ensure that there is no potential for harmful water to enter the pipelines.
