Improving methane production and anaerobic digestion stability of food waste by extracting lipids and mixing it with sewage sludge.

abstract：:In this study, we investigated the effects of electrical treatment on Haematococcus pluvialis growth. The slow growth of H. pluvialis is a major limitation for its mass production. We discovered that electrical treatment may promote the growth of H. pluvialis. To evaluate optimal growth-promoting conditions, the algal...
