1. Investigation of nitrogen recovery from concentrated wastewater
Sammanfattning : Nitrogen recovery from wastewater treatment for fertilizers is a research topic that exists at the intersection of multiple topics important to the future of sustainable society. First, nitrogen recovery from wastewater implies a departure from the current methods of nitrogen mitigation, which involve nitrogen removal by conversion of various aqueous species to inert nitrogen gas.

2. Fault Detection in Wastewater Treatment : Process Supervision to Improve Wastewater Reuse
Sammanfattning : As wastewater treatment plants transition to water resource recovery facilities, the need for improved control and consequently supervision increases. Despite the large volume of research that has been performed on this topic, the use in industry is scarce. LÄS MER
3. Phosphorus recovery for fertilisers from dairy wastewater – Sustainability assessment at early stages of technology development
Sammanfattning : A reduction in the availability of phosphate rock resources for fertiliser production coincides with an increase in phosphorus-rich dairy wastewater in Europe. This confluence of events has led to the development of technologies for phosphorus recovery from dairy wastewater and the use of the products as fertilisers in agriculture. LÄS MER
4. Waste Heat Driven Membrane Distillation for Industrial Wastewater Treatment
Sammanfattning : The European Union has placed a high priority on reaching the goals described in the 2030 Agenda for Sustainable Development. This aim has provided added momentum to member-state environmental regulatory authorities to further tighten the discharge limits of industrial wastewater. LÄS MER
5. Sustainable building ventilation solutions with heat recovery from waste heat
Sammanfattning : The energy used by building sector accounts for approximately 40% of the total energy usage. In residential buildings, 30-60% of this energy is used for space heating which is mainly wasted by transmission heat losses. A share of 20-30% is lost by the discarded residential wastewater and the rest is devoted to ventilation heat loss. LÄS MER
