“…During the past 30 years, there have been immense R&D involving AOPs, particularly for two reasons, namely (i) the diversity of technologies involved and (ii) the areas of potential application. 5 Although water and wastewater treatment is by far the most common area for R&D, AOPs have also found applications as diverse as groundwater treatment, 6 soil remediation, 7 municipal wastewater sludge conditioning, 8 ultrapure water production, 9 volatile organic compound treatment, 10 and odour control. 11 …”

“…In neutral and acidic conditions, the effect of TAP on dewaterability, which finally decreased CST to approximately 28.5 s, was similar. The only difference was that CST decreased rapidly within the initial 20 min in acidic conditions, which was attributed to the fact that the activation energy in acidic conditions (100-116 kJ/mol) was less than in neutral conditions (119-129 kJ/mol) [38]. As for conventional WAS in neutral conditions, it is unnecessary to adjust pH prior to TAP treatment.…”

Phosphorus is a nonrenewable and irreplaceable limited resource, and over 90% of phosphorus in influenttransfers into sludge in wastewater treatment plants. In this study, thermally activated peroxydisulfate (TAP) treatment was combined with struvite precipitation to enhance waste activated sludge (WAS) dewaterability and phosphorus recovery. TAP simultaneously enhanced dewaterability and solubilization of WAS. The optimal conditions of TAP treatment were PDS dosage 2.0 mmol/g TSS, 80 °C, pH 4.0~7.0 and 40 min, which enhanced dewaterability (capillary suction time (CST) from 94.2 s to 28.5 s) and solubilization (PO43−-P 177.71 mg/L, NH4+-N 287.22 mg/L and SCOD 10754 mg/L). Radical oxidation disintegrated tightly bound extracellular polymeric substances (TB-EPS) and further released bound water. The acidification effect neutralized the negative surface charge of colloid particles. Compared with thermal hydrolysis, TAP effectively promoted the release of PO43−, NH4+ and SCOD. Cation exchange removed most Ca and Al of the TAP treated supernatant. The optimal conditions of struvite precipitation were Mg/P 1.4 and pH 10.0, which achieved phosphorus recovery of 95.06% and struvite purity of 94.94%. The income obtained by struvite adequately covers the cost of struvite precipitation and the cost of WAS treatment is acceptable.

“…Under ISCO conditions, organosulfates are stable with respect to hydrolysis and are probably less reactive with S 2 O 8 2– than their parent compound, but continued oxidation is possible through further reactions with SO 4 •– . Reaction with the HO • produced during persulfate decomposition also may result in further transformation and eventually mineralization. − …”

Oxidation of organic contaminants by sulfate radical (SO 4•− ) is becoming more popular for the treatment of hazardous waste sites by in situ chemical oxidation and industrial wastewater by advanced oxidation processes. It is well documented that SO 4•− can produce oxygen-containing transformation products similar to those produced by hydroxyl radical-based treatment processes, but SO 4•− also has the potential to produce organosulfates by radical addition. Experiments conducted with a suite of 23 aromatic and five aliphatic compounds, including several contaminants typically detected at hazardous waste sites, demonstrated the formation of at least one stable sulfate-containing product for 25 of the compounds. These compounds likely exhibit higher mobility in the subsurface due to a lower affinity for surfaces (e.g., aquifer solids and activated carbon) than most other transformation products. Although the health risks associated with organosulfates are still uncertain, some aromatic organosulfates produced in this study (i.e., phenyl sulfate and p-cresyl sulfate) are known to be harmful uremic toxins. Further study of the formation, fate, and toxicity of organosulfates may be necessary before SO 4•− -based treatment processes are more widely employed.
