If this opportunity is for you please get me guide about yellow sludge.
I run membrane bioreactor for Artificial  starch wastewater treatment. operated @ SRT= 10 day hrt=12hr. after about 10day sludge color changes from brown to yellow and COD removal efficiency decreased sharply. I know that nitosamine produced in this MBR but don't know why this matter produced. Thanks if you get my guide.
