This paper discusses the resource utilization of Fe-rich sludges generated as waste
products from water treatment, hydrometallurgy, surface finishing, and dye chemical …

Cr (VI) is present naturally as Cr 2 O 7 2-and its negative charge repels electrons (e-),
preventing direct reduction to Cr (III). The Cr (VI) reduction process consumes H+ …

Composite nanofiltration membranes offer advantages because of synergetic effects among
the constituent materials' properties. However, the sustainability of both the membrane …

The Brayton refrigeration air cycle for electroplating wastewater treatment can achieve 100%
recovery of water, but there is air condensation during the expansion, which can damage the …

Erdite rods were massively produced via a one-step alkaline heating route with the complete
recycling of waste waterwork sludge. The sludge was a mixture of Fe, Mn, Al, and Si, but …

Mud-water separation efficiency and removal efficiencies of pollutants are relatively low in
conventional activated sludge processes. In this study, zero-valent iron (ZVI) and Fe 3+ were …

A low-temperature hydrothermal process was developed to synthesize erdite adsorbent from
a solid waste sludge contained 10.2% Fe, 6.2% Al and 1.4% Si, alongside 59.5% water …

Abstract The nitrite (NO 2–) accumulation in partial denitrification (PD) offers the possibility of
widespread application of anammox process. In this study, the rapid establishment of PD …

Pilot scale production of one-dimensional (FeS2) nn− rods was performed by using an
automatic 20 L vessel at 80° C under atmosphere condition with the resource utilization of …

In this study, red mud was used as the main raw material to prepare polyaluminum-ferric
chloride (PCFA) with high added value. The effects of the liquid–solid ratio, reaction …
