Electrical voltage application as a novel approach for facilitating methanogenic granulation

[Display omitted] •Electrical voltage (EV, 0.3 V) was applied for facilitating granulation in UASB.•EV could form big, settleable, and hydrophobic granules within 50 d.•EV also increased the specific methanogenic activity up to two times.•Pseudomonas and Methanosaeta relative abundances were 17 and...
