Wastewater & sewage sludge investigations

Sewage sludge is produced during the purification of wastewater and is also a nutrient and pollutant sink.

Despite its waste nature, it is therefore a valuable resource that should be used in accordance with the Closed Substance Cycle Waste Management Act.

The 2017 amendment to the Sewage Sludge Ordinance created the legal framework for a future phosphorus recovery obligation for large wastewater treatment plants (> 50,000 population equivalents) from sewage sludge and from sewage sludge ash.

Due to the simultaneous restriction of agricultural application in fertilizer legislation, thermal (pre-) treatment is therefore increasingly coming to the fore for operators of large wastewater treatment plants.

The various recycling methods and regulations result in a wide variety of analytical requirements - this is where expert competence is needed.

With decades of experience, SGS is at your side nationwide in the field of analysis and sampling of sewage sludge and wastewater, and together we develop solutions for your recycling route in accordance with the applicable regulations.

In addition to the analyses required by the Sewage Sludge and Fertilizer Ordinance, we can meet all the requirements of your local disposal companies at the highest quality level - confirmed by DAkkS and our accreditation according to DIN EN ISO/ IEC 17025.
