The performance of catalytic ozonation in the removal of organic contaminants from actual petrochemical ,wastewater, was studied using iron‐nickel foam as catalyst (Huang, Luo, Xu, Zhang, & Li, 2019). Catalytic ozonation not only improved the biodegradability of the petrochemical ,wastewater, but also enhance the removal of nutrients and heavy metals.

Titration - Wikipedia

Titration, (also known as titrimetry and volumetric analysis) is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte (a substance to be analyzed). A reagent, termed the titrant or titrator, is prepared as a standard solution of known concentration and volume. The titrant reacts with a solution of analyte (which may also be termed ...

Activated carbon (PPAC) from pomelo peels was prepared by carbonization and KOH activation. The performance of PPAC was assessed by removing ,acid, red 88 (AR88) in aqueous solution. The most suitable activation processes were found by orthogonal experiments, aimed to achieve the maximum of removal capacity of AR88. Moreover, the possible mechanisms of adsorption were studied through the …

A more promising alternative for ,wastewater, remediation is the combination of the activated sludge treatment with membrane ,filtration, process. This technology, also known as membrane bioreactor (MBR), differs from CAS since a membrane module is used instead of the secondary clarifier to separate activated sludge from the final effluent ( Xing et al., 2000 ).

In the process, the heavy metal bearing, wastewater, is mixed with a divalent, ferrous, salt, usually, ferrous, sulfate (FeSO^*7HaO). This, ferrous, salt is widely available and results as a waste product during the production of steel or titanium dioxide. The divalent iron ion (Fe*"1") will coexist with the, nonferrous metal, ion in solution.
