AbstractHigh-salinity organic wastewaters pose a major challenge for conventional wastewater treatment processes. Here we propose dialysis as an innovative solution to overcome this challenge. Dialysis uses an ultrafiltration (UF) membrane that allows the passage of salts while rejecting the organic substances, operating in a bilateral countercurrent flow mode without the application of hydraulic pressure.

AbstractSoil dissolved organic matter (DOM) is crucial to atmospheric, terrestrial and aquatic environments as well as human life. Here, by characterizing DOM from 89 grassland soils throughout China, we reveal the spatial association between DOM geochemistry in the dry season vs annual ecosystem exchange and cancer cases.

AbstractCoagulation is one of the most common treatment processes for the removal of contaminants from water, representing ‘the first line of defence’ for drinking water safety. However, the macroscopic and descriptive theories of trivalent metal-based coagulation have limited the optimization of its performance in the removal of natural organic matter species, which are major precursors of hazardous disinfection by-products.

Correction to: Nature Water https://doi.org/10.1038/s44221-023-00037-0, published online 9 March 2023. In the original version of this article, an incorrect version of Fig. 4 was displayed. The original Fig. 4 was inconsistent with the source data uploaded. The source data were correct. The scale of the y-axes in Fig. 4d and the inset graphs of 4a and c have been updated. The data points have been replotted for the Local Mg2+ line in Fig. 4b and the “Local” line in Fig. 4e.

Preparation of electrically conductive CNTs-PA membraneThe CNTs-PA membrane was fabricated by the interfacial polymerization (IP) of PIP and TMC, following the procedures reported in our previous work11,12. First, CNTs nanofilm was prepared by vacuum filtration of hydroxyl-functionalized MWCNTs dispersion onto the surface of the PES MF membrane. Then IP was performed on the surface of the CNTs nanofilm. Specifically, the PES MF membrane was soaked in ethanol for 30 min.
