Optimization of electric energy consumption in degradation of Indigo Carmine based on a new cylindrical batch suspension photocatalytic reactor designing concerning the main engineering parameters such as mixing, reaction kinetic, mass transfer, catalyst illumination, and inherent potential of contaminant was done. The most degradation efficiency was observed within in air flow rate 1.2L. min . Applying optimum condition eventuated 76.09% TOC reduction after 60 min reaction time. The results show that designed reactor is extremely affective in reduction of operational cost.

In order to decolorize, waste cooking oil, a dark red close to black solution from homes and restaurants, was subjected to 60 Co c-ray/H 2 O 2 treatment. By virtue of UV/ Vis spectrophotometric method, the influence of Gamma irradiation to decoloration kinetics and rate constants of the waste cooking oil in the presence of H 2 O 2 was researched. In addition, the influence of different factors such as H 2 O 2 concentration and irradiation dose on the decoloration rate of waste cooking oil was investigated. Results indicated that the decoloration kinetics of waste cooking oil conformed to the first-order reaction. The decoloration rate increased with the increase of irradiation dose and H 2 O 2 concentration. Saponification analysis and sensory evaluation showed that the sample by 60 Co c-ray/H 2 O 2 treatment presented better saponification performance and sensory score. Furthermore, according to cost estimate, the cost of the 60 Co c-ray/H 2 O 2 was lower and more feasible than the H 2 O 2 alone for decoloration of waste cooking oil.

Coke plant wastewater containing lots of toxic organic pollutants should be treated before being discharged into the environment. It is challenging to treat toxic and refractory compounds using conventional methods. In this study, a UV-Fenton technology was investigated. When the initial COD, NH 3 -N concentration and SS of wastewater were 5080 mg/L, 329.9 mg/L, and 847.7 mg/L, results showed that the removal rate of COD, NH 3 -N and SS were 88.0%, 58.4% and 99.2% respectively under the optimal reaction conditions. Under the identified optimal condition, H 2 O 2 concentration is 75 mmol/L, the concentration ratio of H 2 O 2 and Fe 2+ is 3:1, and original pH is 4 within 30 min. GC-MS analysis, revealed that organic substances such as indole and quinoline were degraded effectually.
