Crystallization kinetics and growth of struvite crystals by seawater versus magnesium chloride as magnesium source: Towards enhancing sustainability and economics of struvite crystallization
Shaddel, Sina; Grini, Tonje; Andreassen, Jens-Petter; Østerhus, Stein Wold; Ucar, Seniz (Peer reviewed; Journal article, 2020)The recycling of nutrients from wastewater and their recovery in the form of valuable products is an effective strategy to accelerate the circular economy concept. Phosphorus recovery from wastewater by struvite crystallization ... -
Seawater as Magnesium Source for Struvite Crystallization in Wastewater - An assessment of seawater as an alternative magnesium source of struvite production in wastewater treatment plants
Grini, Tonje (Master thesis, 2018)Phosphorus (P) from wastewater and agricultural fertilizers are discharged to water bodies and contribute to eutrophication. At the same time, phosphate rock used for fertilizer production is a non-renewable resource that ... -
Sjøvann kan framskynde overgangen til sirkulærøkonomi og effektivisere fosforgjenvinning
Shaddel, Sina; Grini, Tonje (Journal article; Peer reviewed, 2018)Seawater can accelerate the transition towards circular economy and make phosphorus recovery more efficient. Phosphorus (P) from rock phosphate is a limited resource, and increasing demand will make the phosphorus situation ... -
Struvite crystallization by using raw seawater: Improving economics and environmental footprint while maintaining phosphorus recovery and product quality
Shaddel, Sina; Grini, Tonje; Ucar, Seniz; Azrague, Kamal; Andreassen, Jens-Petter; Østerhus, Stein Wold (Peer reviewed; Journal article, 2020)Seawater, as an alternative magnesium source, has the potential to improve the overall economics and environmental footprint of struvite production compared to the use of pure magnesium salts. However, the dilution effect ...
