Methods for Enhancing the Methane Production from Wastewater - a Review
نویسنده
چکیده
Developing cost-effective technologies to solve water pollution problems are critical to the sustainable development of human society. Wastewater treatment systems are now experiencing a paradigm shift. Whereas they once merely aimed to remove pollutants, they now also attempt to recover resources while minimising energy consumption. Anaerobic digestion (AD) process is one of the oldest technologies. AD is considered to be an efficient, sustainable, and technically feasible way to treat wastes as it offers the benefits of mass reduction, pathogen removal and generation of methane. The recent demand in renewable sources of energy has boosted application of AD. Wastewaters of various complexity can be treated by AD. The aim of this review is to summarize the recent technological advances in the area of anaerobic digestion for the generation of energy from the wastewater.

Zero Valent Iron Significantly Enhances Methane Production from Waste Activated Sludge by Improving Biochemical Methane Potential Rather Than Hydrolysis Rate
Anaerobic digestion has been widely applied for waste activated sludge (WAS) treatment. However, methane production from anaerobic digestion of WAS is usually limited by the slow hydrolysis rate and/or poor biochemical methane potential of WAS. This work systematically studied the effects of three different types of zero valent iron (i.e., iron powder, clean scrap and rusty scrap) on methane pr...

متن کاملMitigating ammonia inhibition of thermophilic anaerobic treatment of digested piggery wastewater: use of pH reduction, zeolite, biomass and humic acid.
High free ammonia released during anaerobic digestion of livestock wastes is widely known to inhibit methanogenic microorganisms and result in low methane production. This was encountered during our earlier thermophilic semi-continuously fed continuously-stirred tank reactor (CSTR) treatment of piggery wastewater. This study explored chemical and biological means to mitigate ammonia inhibition ...
