Hydroponics Water Treatment – USA

Location: Portland, OR

Summary: In this application the user operates a facility that cultivates Marijuana for medicinal
purposes. They use a significant amount of water that is used to feed the plants and is then
discharged to the city drain. They are in need of cleaning their waste water to be able to reuse
