Electrocoagulation/flotation can effectively recycle eutrophic algae.
Metals in recycled algae due to ECF changes the optimum hydrolysis conditions.
Recycling algae can improve water quality and produce third-generation biofuels.
There are 33–58 mg glucose/g algae and 70–98 mg xylose/g algae in recycled algae.
Using ECF system (Fe) to recycle algal biomass improve the algal hydrolysis reaction.
