Niche membrane technologies, such as organic solvent nanofiltration (OSN), offer considerable energy and operation cost reduction compared with conventional separation methods. However, despite their many advantages, industrial implementation is hindered by small specialized datasets, which hinders the development of more advanced prediction In this study, we developed a medium-throughput syste...

the removal of organic precursors of disinfection by-products (dbps), i.e. natural organic matter (nom), prior to disinfection is considered as the most effective approach to minimise the formation of dbps. trihalomethanes (thms) as the main group of dbps are categorized and considered to have the potentiality of increasing the rate of liver, kidney and cns adverse effects. this study which pre...

under favorable soil conditions such as existence of easily destructible organic compounds, balanced heat and moisture, adequate ventilation and abundant nutrients, organic materials are mineralized. once mineralizing occurs, mineral elements like p, s, ca, mg, k and other cations are released. a related study was conducted to determine the effect of seven organic fertilizers (leaf mold (lm), r...

Context. Hot corinos are compact regions around solar-mass protostellar objects that very rich in interstellar Complex Organic Molecules (iCOMs). How the abundance of these molecules is affected by environmental physical conditions still an open question. More specifically, addressing this point key to understand our own chemical origins since Solar System formed a large cluster low- high-mass ...

The global AsIII-oxidizing activity of microorganisms in eight surface soils from polluted sites was quantified with and without addition of organic substrates. The organic substances provided differed by their nature: either yeast extract, commonly used in microbiological culture media, or a synthetic mixture of defined organic matters (SMOM) presenting some common features with natural soil o...

introduction conventional water treatment consist of unit processes include coagulation, flocculation, clarification, filtration and disinfection that goal is removal of turbidity, color and certain bacterial species. in filtration process flocculated substances that have not removed in pervious stage are sediment. filter media is often silica sand that removal mechanism is complex and consists...
