High svi in wastewater process
WebHowever, in the existing studies of microalgal MFCs, microalgae only provide high dissolved oxygen through photosynthesis and mostly operate in intermittent mode, and microalgae are not involved in the wastewater treatment process, so there are still problems such as low N and P removal rates and organic matter removal efficiency to be improved. WebEffluent BOD results may be below requirements, but TSS levels can still be high. SVI = 100 to 200 mL/g. Most activated sludge plants seem to produce a clear, good-quality effluent …
