Noardling Desah - Advanced Blackwater Treatment System
Our advanced blackwater treatment system combines a thermophilic digester with nitrogen and phosphate removal modules, ensuring lower treatment costs. The system produces biogas as a renewable energy source, removes micro-pollutants and offers struvite recovery, recovering valuable minerals for applications in energy production and agriculture. This innovative technology contributes to a circular economy and supports cost savings and environmentally friendly solutions.

Desah applies its technologies in high-profile projects worldwide. Below are some leading cases in which Desah realises local and wastewater treatment.
Helsingborg, Sweden - example of circular sanitation
In the circular housing estate Oceanhamnen, Desah designed and delivered an innovative treatment system in which black and grey water is separated and processed directly at source. This project was awarded the Global Water Award 2022 and previously won the Innovation Challenge 2015.
Noorderhoek, Sneek - the world`s first circular housing estate
In the Noorderhoek district, 207 homes have been connected to Desah`s innovative water treatment system. Greywater and blackwater are collected separately and processed locally, drastically reducing drinking water consumption.
Government offices in The Hague - sustainable sanitation concept for 6,000 civil servants
At the Rijkskantoor on Rijnstraat in The Hague, all wastewater is treated locally with an advanced Desah system. This innovative sanitation concept saves water, reduces treatment costs and recovers energy and nutrients.
