A bombastic approach to remove 2,4,6- Trichlorophenol (TCP) from simulated wastewater via Progressive Freeze Concentration (PFC): effect of operation time & optimization by using Response Surface Methodology (RSM): article

Nowadays, chemical industries have discharged the wastewater which contain a phenolic compound such as 2,4,6-trichlorophenol (TCP). This compound is toxic and hazardous as it belongs to a group of common environmental pollutant. It contributes to the shortages sources of clean water due to increment of population and rapid development of chemical indusl Therefore, the sources of water must be explored in order to get continuously supply of pure water. One of the ways to get pure water is by purifying the wastewater. This research is using progressive freeze concentration (PFC) to purify the wastewater. PFC is the process where the ice crystal is generated on the wall of the crystalliser which contain pure water through cooling process. The effect of operating time was then investigated on the performance of the PFC system through Effective Partition Constant (K) value and TCP reduction (%). TCP solution was used a simulated wastewater sample. The optimum condition was found at 40 minutes, resulted in the lowest K and highest TCP reduction (%). Furthermore, Response Surface Methodology (RSM) was used for optimization of two parameters which are initial concentration and operating time. The K value and TCP reduction (%) were determined to investigate the efficiency of this system. STATISTICA oftware is then implemented to find the operating conditions. The best response for K and TCP reduction (%) were predicted by ANOVA were 0.13-(i and 76.5jg8% respectively
