Chemical sludge conditioning in combination with different conventional and alternative dewatering devices chamber filter press, decanter and Bucher press


, : Chemical sludge conditioning in combination with different conventional and alternative dewatering devices chamber filter press, decanter and Bucher press. Journal Of Environmental Science And Healtha, Toxic Hazardous Substances & Environmental Engineering: 13, 1521-1527. Ef

The Kemicond process for sludge conditioning consists of chemical treatment with sulphuric acid and hydrogen peroxide at a pH-value of approximately 4 followed by a dewatering unit. It is shown that chemical treatment can improve the dewaterability of ferruginous digested sludge. It is concluded that the Fenton process as well as the oxidation of organics and the formation of iron hydroxo complexes are important reaction mechanisms.
