What is Struvite?

Struvite crystallization in the pipeline and its accumulation cause significant environmental and industrial issues such as pollution problems like eutrophication, odor formation, clogging in the pipelines, damage in the equipment and reduction in the process efficiency. Adapting struvite crystallization under controlled conditions not only eliminate these problems but also enables production of a high-value added fertilizer product. It can substitute commercial fertilizers with its high phosphorous and nitrogen content, and there are several studies that shows struvite fertilizers is superior to other commercial fertilizers. Struvite sources can be sewage sludge, industry waste liquors, landfill, anaerobic digester supernatant, WWTPs, poultry manure, swine wastewater, urine, semiconductor wastewater, vegetable processing industry and yeast urine; and utilization of these waste increases sustainability and eliminates pollution. Also, creating value from wastewater will meet the socio-economic challenges of rural farmers in Turkey by eliminating misuse of biogas plant effluents on agricultural fields, instead developing high-value state of-art fertilizers.
