Helsingborg is one of the fastest growing cities in Sweden. It is expected that in 15 years the city has attracted more than 40,000 new residents. To meet this grow, 1,000 new homes are being built each year. One of the first new districts is Oceanhamnen, part of the H+ project.
In the Oceanhamnen district, a new innovative and sustainable wastewater treatment facility is implemented. The new residences and office buildings will be equipped with vacuum toilets and kitchen grinders. Black water, grey water and green waste are collected and treated separately. Desah has made the conceptual design for the treatment installation.
With this new sanitation design, DeSaH already won the Swedish innovation prize in 2015 in the “Blackwater and Food Waste Challenge” in the category “Treatment plant”, aimed at the recycling of waste streams. The jury report states: “DeSaH has developed a compact wastewater treatment plant, a concept that contributes to an increased recirculation of water, nutrients and energy.”
Now, in 2022 this particular project has won the Global Water Awards 2022 in the category “Wastewater Project of the Year”.
Desah realized the treatment installation for the source separated wastewater, emphasizing the recovery of valuable raw materials such as fertilizer and biogas, as well as heat recovery.
Desah is responsible for:
- Digestion of toilet water (black water)
- Digestion of food waste
- Hygienization of sludge
- Grey water treatment
- Heat recovery
