A huge production of waste activated sludge (WAS) has been a burden for wastewater treatment plants (WWTPs) with high disposal cost and little benefit back to wastewater purification. The short-chain fatty acids (SCFAs) produced by a short-term acidogenic fermentation of WAS before methane production have been proven to be a high-quality carbon source available for microbial denitrification process. The dual purpose of full recovery of fermentation liquid products and facilitating disposal of residual solid waste necessitate an efficient solid-liquid separation process of short-term fermentation liquid.

- The study explores how regulating the carbon cycle and reducing greenhouse gas emissions in wastewater treatment plants (WWTPs) can enhance sustainability, despite current dependence on external carbon sources.
- It highlights a pilot experiment where carbon was recovered from primary sludge through short-term fermentation and used for denitrification in a wool processing WWTP, improving both carbon and nitrogen management.
- The results showed a 9.1% reduction in sludge volatile solids, offsetting over half of the external carbon needed, while achieving an 8.05% reduction in indirect greenhouse gas emissions, indicating the benefits of optimizing carbon flow in WWTPs.
The title compound, dineodymium(III) tetra-molybdate(VI), has been prepared by a flux technique and is the second polymorph of composition Nd(2)Mo(4)O(15). The crystal structure is isotypic with those of Ce(2)Mo(4)O(15) and Pr(2)Mo(4)O(15). It features a three-dimensional network composed of distorted edge- and corner-sharing NdO(7) polyhedra, NdO(8) polyhedra, MoO(4) tetra-hedra and MoO(6) octa-hedra.
