The effects of ultrasound and electrocoagulation on removal of manganese from wastewater

In this paper the effect of ultrasound and electrocoagulation on removal manganese from synthetic wastewater was investigated. It shown that 20 kHz alone is not very efficient for removal, but it enhances efficiency electrocoagulation. also settling has a great process because stabilizes flocs. A total four laboratory-scale experiments were conducted, optimal experiment included 10 minutes with iron electrodes. Under these conditions, 89.0 % removed an operating cost 0.13 EUR/mg Mn. Adding replacing immersed ultrasonic probe, increased 3000-fold, making probe method unviable large-scale application.
