Vertical Flow Constructed Wetlands, which integrates natural ecological components such as soil, filler, plants, and microorganisms in a unit, is an effective rural domestic sewage treatment technology. Based on the principle of waste recycling, garbage ceramsite and soil were used as the...

Heterogeneous peroxymonosulfate (PMS) activation by cobalt-based catalysts has drawn much attention due to the high-performance property of cobalt ions (Co(II/III)) to activate PMS. However, the leaching and residue of Co(II/III) in water is still a hurdle to the long-term development of...

Raw biogas is a valuable renewable energy but usually requires upgrading. The mixed LED (light-emitting diode) light wavelengths achieved much better microalgae growth than that of the monochromatic. The best LED light wavelength mix ratio for both biogas upgrading and biogas slurry nutrient...

Chlorella sp. is a microalga that could be utilized effectively in the simultaneous biogas upgrade and biogas fluid nutrient removal. Mixed light-emitting diode (LED) light wavelength treatments (red:blue=1:9, 3:7, 5:5, 7:3, and 9:1) were more appropriate for microalgal growth than monochrome...
