Improvement of phosphorus release from sludge by combined electrochemical-EDTA treatment.

In this paper, combined with the addition of ethylenediaminetetraacetic acid (EDTA), the electrochemical treatment of waste activated sludge (WAS) was investigated to explore its effect on the release of phosphorus (P) from WAS. The results showed that during the electrochemical treatment, the addition of EDTA could significantly promote the release of P from the WAS to the supernatant, the optimal amount of EDTA was 0.4 g/g total suspended solids (TSS), when the release of total dissolved phosphorus (TDP), organic phosphorus (OP) and molybdate reactive phosphorus (PO-P) were 187.

Interaction energy and detachment of magnetic nanoparticles-algae.

Magnetic separation, a promising bioseparation technology, is confronted with the challenges in recovery and recycle of magnetic matters during algae harvesting for biofuel extraction. The thermodynamic method was used to characterize the surface interactions between MNPs and algae cells. Three methods were adopted to detach magnetic nanoparticles-algae (, , and ) and recover magnetic nanoparticles (MNPs) in this study.

Characterization of 19 polymorphic SSR markers in (Lemnaceae) and cross-amplification in .

Premise Of The Study: Polymorphic microsatellite primers were developed for greater duckweed, (Lemnaceae), to investigate genetic diversity and structure for application in a bioremediation program.

Methods And Results: A total of 401 publicly available . whole-genome shotgun sequences were searched for simple sequence repeat loci of two or more nucleotides.
