Climate change is considered to be one of the main challenges to urban wastewater systems in future decades. It is estimated that climate change has a dual effect on wastewater treatment (WWT) plants.
Wastewater Treatment in Greenland Report R-265 2012 Today all wastewater in Greenland is discharged untreated to the recipients. However, wastewater treatment in the Arctic is challenging due to e.g. the cold climate and settlement pattern. Decentralized solutions, e.g. composting or anaerobic digestion of the blackwater, may be well suited for Greenland. This thesis presents results from
Diagnosis Problems in Wastewater Settling Abstract Solids-liquid separation is of crucial importance in wastewater treatment systems, in particular in activated sludge systems. This is true in a wide spectrum of operating conditions. During severe hydraulic loading the clarifier becomes the bottle-neck. Likewise, the long term development of the microbial species determines the floc structure

The ammonia based plating process produced excellent finished parts, but meeting the wastewater discharge permit and operating costs proved difficult.
Wastewater Treatment in Greenland Report R-265 2012 Today all wastewater in Greenland is discharged untreated to the recipients. However, wastewater treatment in the Arctic is challenging due to e.g. the cold climate and settlement pattern. Decentralized solutions, e.g. composting or anaerobic digestion of the blackwater, may be well suited for Greenland. This thesis presents results from
