Wastewater

Towards a healthy and circular water chain

The water chain is in transition: wastewater needs to be cleaner and reused in a better way. The aim is to achieve future-proof wastewater treatment plant that contributes to a climate-neutral and circular economy.

Removal of (micro) contaminants

There is growing awareness of the extent of human impact on water systems. In order to ensure the quality of life for ourselves and for nature (more) stringent requirements are necessary for wastewater that is discharged. For example, requirements for the removal of nutrients, pharmaceutical residues, PFASs and microplastics.

In recent years, Witteveen+Bos has specialised in designing post-treatment plants to remove these substances from the water. We also conduct research and pilot projects to scale up new techniques in this field to full-scale plants.

High-quality water

We have extensive knowledge of and experience with biological and physico-chemical waste-water treatment, where we choose the treatment principles that fit the desired quality for projects: from meeting discharge requirements to providing high-quality water for specific purposes (such as industrial processes).

Reuse of energy and raw materials

Our expertise also includes saving energy and chemicals and reducing greenhouse gas emissions during the operation of wastewater treatment plants.

Witteveen+Bos has years of experience in designing systems for the efficient processing of sewage sludge and sustainable application of biogas based on proven concepts and new technologies. During projects we also separate raw materials such as nitrogen, phosphate and fresh water from wastewater so they can be reused.

Process water for industry

Witteveen+Bos is also active in drinking water and process water for industry. Because these areas of expertise are tangentially related to wastewater, we can exchange insights from - and experiences with - different purification environments. For instance, we can use advanced drinking water technologies for wastewater purposes.

Witteveen+Bos also applies a source approach, which implies advising industries, among others, on making their process water systems more sustainable in order to increase the quality of their discharge water.
