Clear surface water is of vital importance to man and nature. The treatment of wastewater is therefore essential. Together with public water companies and the industry, Grontmij tries to limit the emissions from pollution. We offer advice on sustainable and innovative solutions, and add future value to them, so future generations also have reliable water. Water is also precious, which is why we always look for adequate solutions for the (re-) use of water taking into account the financial context.

Flexible formula
Grontmij can support your project within a flexible framework: as a consultant for the selection of technology manage detailed design (including technical specifications and supervison of construction works) and if needed, as turnkey or design & build contractor. Also during start-up and operational management, our experts are ready to have your technical installation work at its best.

Water purification and water treatment, choose the best available technique
Grontmij designs and realises performant installations for water purification and water treatment for both household and industrial wastewater. Experience of many years guarantees the use of the Best Available Technique at an affordable price.

Grontmij designs physico-chemical and biological installations (aerobe or anaerobe) for water treatment with the integration of a.o. substantial nutrient removal and effluent polishing. In doing so, we pay a lot of attention to a reliable operational management and a minimal production of sludge. The use of pilot installations helps to choose the right advanced techniques for water treatment, such as membrane bioreactors (MBR) or advanced nitrogen removal (SHARON©) Our engineers strive for minimal energy use and maximum energy recuperation through a well-conceived technical concept matched with experience in operational management.

In addition to ‘technical’ installations, Grontmij has also experience with small-scale installations in which ecological concepts (reed fields, bio-rotor, constructed wedlands, plant purification) are applied.
