چکیده

BACKGROUND Under scarcity of freshwater, the reuse and low-cost technological solutions applied to wastewaters seek reduce contamination users freshwater biota. RESULTS A cellulose membrane was doped with silver nanoparticles filter urban wastewater (UW) from a city in Argentina. The total amount coliforms Escherichia coli decreased by 99.6% 99.9%, respectively. leak 275 ng L?1, analyzed square wave anodic stripping voltammetry. Silver tested on HepG2 A549 mammalian cell lines showed no toxicity broad concentration range. Calculation organic matter provided dead bacteria post-filtration 347 ?g L?1 proteins, 148 nucleic acids, 57 lipids, 53 polysaccharides, indicating high availability matter. retention inorganic salts 78.5% ammonia, 6.2% nitrates, 97.6% nitrites, 19.2% phosphates. In post-filtered UW, Lactuca sativa germination test early seed between 90% 95% all dilutions tested. range 6.25% 50.0%, filtered UW significant differences hypocotyl but difference radicle length (mm) compared control made synthetic media (P < 0.05). CONCLUSION development based membranes allowed for domestic purposes garden irrigation. © 2021 Society Chemical Industry (SCI).

Emitter and filter tests for wastewater reuse by drip irrigation

Agriculture is the main user of water in Italy, as in most regions of the world. Particularly in Mediterranean regions, where it is more difficult to meet the agricultural water demand with conventional resources, wastewater reuse represents a viable option. Drip irrigation is particularly suitable for wastewater reuse because it minimises the health risks to farmers and product consumers due t...
