Abstract |
The objective of the project was to evaluate methods of removing phthalates from a plastics molding and forming contact cooling and heating water. Two technologies were evaluated: (1) ferric chloride assisted clarification; and, (2) activated carbon adsorption. The actual wastewater was spiked with about 2 mg/l of each of the following phthalates: bis (2-ethylhexyl), di-n-butyl and dimethyl. The spiked wastewater was then used to conduct the bench-top jar tests. The ferric chloride assisted clarification reduced the bis (2-ethylhexyl) phthalate concentration by about 90 percent but did not remove either of the other two phthalates. A series of powdered activated carbon jar tests were conducted on the spiked wastewater and adsorption isotherms were generated for each of the three phthalates. |
