abstract
Phosphorus and nitrogen are important elements, making a major contribution to agricultural and industrial development, but their release to natural water bodies are the main causes of eutrophication. In addition, the demand for fertilizers is increasing, energy prices are rising and global phosphate reserves are declining. Meaning that besides meeting the nutrient standards, nutrient removal should be replaced by nutrient recovery. This requires both changes in wastewater treatment technologies and implementation of new processes. Also the commercializing and potential users for the recuperated nutrients making part of these changes. For the recovery of phosphorus (as phosphate) the application of a struvite precipitation process in a WWTP is beneficial to reduce the consumption of phosphate rocks, and to obtain a recovered product that can be used as a fertilizer or used as raw material in the phosphorus industry. Currently, only few full-scale struvite crystallization plants exist. This is due to the lack of information about the benefits of struvite as a fertilizer, its value on the market, and problems related to the crystallization process. Nitrogen in current WWTP is removed by nitrification-denitrification. The nitrogen (as nitrate), that remains in the wastewater after anaerobic digestion and struvite precipitation could be recovered in the brine that results after the treatment of this wastewater with a membrane bioreactor and reverse osmosis. In this study we want to find the potential users and markets of these “natural stable fertilizers” (struvite and the brine) in Belgium or abroad.
