Industrial wastewater treatment

Optimize industrial wastewater treatment for cost effective compliance

Industrial wastewater treatment is an inevitable challenge for many plant operators, with wastewater a byproduct of multiple industrial processes. Reusing wastewater in secondary capacities can bring efficiencies. When this is not possible discharge to a sewer or nature is the only option. Yet strict regulations for human and environmental safety make treatment of wastewater for discharge a costly and complex task. Our industrial wastewater treatment portfolio can ensure optimal processes.

How we can help

Offering a complete portfolio of monitoring and analysis technologies, Endress+Hauser enables its customers to treat industrial wastewater more efficiently and with enhanced compliance, optimizing processes such as:

  • Wastewater reuse

  • Anaerobic digestion

  • Biological treatment

  • Sludge disposal


Wastewater reuse

Wastewater reuse or recycling offers the dual benefits of lowering water intake and minimizing wastewater discharge costs. However, for wastewater to be recycled safely as industrial water it must be treated according to its future use, involving processes such as flotation, sedimentation and filtering.

Wastewater reuse
Our expertise in the field

The Endress+Hauser portfolio enables the accurate monitoring and control of inlet pressure, quality and flow, vital to preventing damage to wastewater filters.

Anaerobic digestion

An efficient pre-treatment process for wastewater with a high Chemical Oxygen Demand (COD), such as from the pulp & paper industries, anaerobic digestion converts a proportion of organic load to biogas. Managing anaerobic digestion effectively necessitates accurate monitoring of multiple parameters throughout the process.

Anaerobic digestion in the digesters
Our expertise in the field

Endress+Hauser offers a complete range of monitoring technologies for total anaerobic digestion process control and optimization, including:

Biological treatment

Often following anaerobic digestion, wastewater with high organic load, such as from the food industry, will be treated biologically to reduce organic content. Ensuring that the right conditions exist to enable biological action is the main challenge with the biological treatment approach, and accurate monitoring of parameters such as ammonium, nitrate and oxygen levels is key.

Biological treatment
Our expertise in the field

Endress+Hauser offers an extensive range of highly adaptable analyzers and sensors enabling accurate monitoring of a multitude of parameters in biological treatment:

Sludge treatment

Both costly and complex, sludge treatment involves processes such as thickening or dewatering and the efficiency of both depends upon accurate monitoring of parameters such as flow, suspended solids and density to ensure optimal use of additives and conditioners.
