Synthesis of [H22·Zr5·WO4·10 P2O7]n·26n H2O by response surface methodology to adsorb Ca(II) in manganiferous wastewater
The presence of calcium challenges the manganese recovery from manganiferous wastewater. In this paper, a kind of mesoporous material named [H22·Zr5·WO4·10 P2O7]n·6n H2O is investigated as an ion exchanger to remove calcium ion from manganese slag percolate. The synthesis of zirconium tungstopyrophosphate (ZWPP) was optimized by response surface methodology , and its adsorption capacity and ...

Behavior of Silica in Ion Exchange and Other Systems
Silica is the second most abundant element found on earth. Although silicon itself (Si) is a glassy insoluble solid, the various oxides (primarily "SiCV) are somewhat soluble in water. Indeed, all natural water supplies contain some dissolved "silica". Many supplies also contain suspended or colloidal silica. Silica, like its sister element carbon, has four covalent bonding sites and can, ...

Multivariate analysis of the transport in an Ion Exchange Membrane Bioreactor for removal of anionic micropollutants from drinking water
The present study focuses on investigating the effects of biological compartment conditions on the transport of nitrate and perchlorate in an Ion Exchange Membrane Bioreactor (IEMB). In this hybrid process, the transport depends not only on the membrane properties but also on the biological compartment conditions. The experiments were planned according to the Plackett-Burman statistical design in ...

DOC Removal by MIEX® Process - Scaling-Up & Other Development Issues
Natural organic matter (NOM) is one of the main parameters which affects water quality and performance of water treatment processes. Current processes including coagulation, oxidation, filtration and adsorption are at times inadequate or uneconomic. Over the last two years, a consortium consisting of ICI Watercare and the Australian Water Quality Centre has developed a new continuous process to ...

Selective DBP Precursor Removal with an Innovative Ion Exchange Process
The City of Chesapeake, Virginia has provided a reliable and safe drinking water to its customers for many years. The City has been providing this drinking water despite a water supply that is extremely high in organics with seasonal outbreaks of chlorides. As a result, the 10-mgd Northwest River Water Treatment Plant receives water that is frequently difficult-to-treat. This water requires very ...
