The Department of Chemistry of the University of Hong Kong (HKU), and a start-up company, EC Innovation Limited, will exhibit their latest invention, “EC Flow System,” at the “InnoCarnival 2023” to be held from Oct. 28 to Nov. 5. This invention can collect agricultural wastewater, remove toxic nitrogen oxides and residues, and then convert it into a solution containing nutrients for irrigation and fertilization. The R&D team hopes that this project can help create a sustainable plantation ecology for the local farming community and even extend it to other regions. HKU mentioned that when fertilizers are added to plants traditionally, only 40 percent of the fertilizer is absorbed, while the remaining 60 percent is discharged. Not only is it a waste, but the fertilizer containing toxic substances will pollute the environment and wreak havoc on marine ecology. The “EC Flow System” can collect agricultural wastewater, remove toxic nitrogen oxides and residues, including nitrates and nitrites (NOx), and convert it into a solution containing nutrients for irrigation and fertilization. Ultimately, it can reduce greenhouse gas emissions, improve water quality, and reduce the cost of fertilizing....Read more https://www.theepochtimes.com/china/hku-links-with-a-start-up-company-in-research-on-turning-agricultural-wastewater-into-reusable-treasures-5513774
