Solidification of Sewage Sludge by PARAFIX

PARAFIX를 이용한 하수슬러지 고형화 방안

Increased quantities of sewage sludge coupled with stringent regulations make it important to develope alternatives for residuals management. The use of PARAFIX as a solidifying agent for sewage sludge was investigated by several tests. Basic physicochemical characteristics, strength, permeability, and leaching characteristics were examined. PARAFIX was found to be very effective in reducing permeability, increasing strength, and immobilizing heavy metals. Based on the tests, it Is ascertained that PARAFIX enhances the solidification of sewage sludge. Also sewage sludge solidified with PARAFIX may be used effectively for construction materials.
