“…Producing agricultural wastewater recovery products in the form of fertilizers (Yang et al, 2022). The resultant liquid comprises 89.75% (NH4)2HPO4 and 10.25% NH4H2PO4, while the solid is a combination of MgKPO4, MgNH4PO4, MgNaPO4, MgCO3 (OH)2, and Mg3(PO4)2, which are rich in P, K, and Mg and contain 73.75 % K, 92.96% P, and an extra 2.73 % N. Both have the potential to be utilized in agriculture, horticulture, and landscaping (Yadav et al, 2022) for the production of KNO3 compounds by recovering nitrogen and potassium. Potassium nitrate (KNO3) is preferred over potassium chloride (KCl) because it interacts favorably with chloride-sensitive plants.…”

Eutrophication is a natural phenomenon in aquatic ecosystems that causes algae and other aquatic plants to overproduce. This process can benefit the ecology in tiny amounts, but too many nutrients can generate hazardous algal blooms and kill fish and other aquatic life. To prevent eutrophication and sustain aquatic ecosystems, agricultural waste water like microalgae production wastewater must be treated. The goal of the project is to get nitrogen and phosphorus out of the wastewater from growing microalgae, which is an agricultural waste water. One way to recover nutrients from wastewater is electrocoagulation. This procedure uses an electric current to create microscopic gas bubbles that collect and remove pollutants from wastewater. According to this study, electrocoagulation reduces phosphate and nitrate in microalgae culture wastewater. Phosphate concentration dropped by 90.20% in the 15th minute, while nitrate concentration dropped by 36.19% in the 30th minute. These reductions may be caused by struvite formation and nitrate conversion to nitrogen gas. This study demonstrates that electrocoagulation is a potential technology for recovering nutrients from agricultural waste water and reducing aquatic ecosystem eutrophication.
