By Ha, Dong Yun Cho, Soon Haing; Kim, Young Kwon; Leung, Solomon W ABSTRACT: This study provides biodegradability of organics in leachate according to their molecular mass distributions (10 KDa).

By Pedros, P B Onnis-Hayden, A; Tyler, Charles ABSTRACT: The purpose of this study was to investigate the nitrification and nitrogen removal from centrate produced in the dewatering process of anaerobically digested sludge, using a single- unit, single-zone submerged attached-growth bioreactor.

By Garg, Anurag Mishra, Indra M; Chand, Shri ABSTRACT: Wet-air oxidation of diluted black liquor (chemical oxygen demand [COD] approximately 3250 to 14 500 mg/L) was performed at mild operating conditions (temperature = 388 to 423 K and total pressure = 0.6 MPa) in the presence of heterogeneous 60% copper oxide (CuO)/ 40% cerium oxide (CeO^sub 2^) catalyst.

By Ni, Jinren Sun, Liyiing; Sun, Weiling ABSTRACT: This paper presents a modification of chemical oxygen demand (COD) monitoring giving a better indication of the pollution level compared with the conventional COD method for rivers with a high content of sediments.
