Removing sulphur-based contaminants and nitrogen-based contaminants from water streams |
| abstract |
A small-scale system for removing hydrogen sulfide and ammonia from a wastewater stream includes a sulfur recovery stage, an ammonia recovery stage, and a separation stage. Sulfur species are oxidized and converted into solid sulfur and solid sulfur species by exposure to a combination of chelated iron and oxidizer. The solid sulfur and solid sulfur species are removed by filtration to yield a sulfur-free stream to which oxidizer is added and electromagnetic radiation is inputted to break the N—H bonds of the ammonia into amine radicals. The combination of additional oxidizer and electromagnetic radiation promotes the creation of water and nitrogen gas. |
