Not a viable option. Better to offer the technology to companies for a lisensing fee and let them remediate the waste and recover some of their losses in the way of H2 fuel. Every company with waste water containing Ammonia will also have other contaminents also. No one wants to get involved with cleaning up someone else's mess. The cost would be too hight to go in that direction. They all are unique and remediation is specialized to each plant. There are no generic water-cleaner-upers. Now that would be a money maker. I work in a chemical plant and maintain the analyzers in those areas. I know how complicated it is.
