Water is a precious commodity, so finding ways to re-use waste water, especially in arid regions is essential to sustainability. Researchers in India have now carried out a study of various waste water filtration systems for kitchen waste water and found that even the most poorly performing can produce water clean enough for horticultural or agricultural use. They report details in the International Journal of Environmental Technology and Management. Recycling domestic wastewater is becoming...

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). Organics with molecular mass values lower than 0.5 KDa were the predominant species in the raw leachate nitrate, and the aerated lagoon process was very effective in treating these highly biodegradable organics; the Fenton's oxidation process was very effective in treating not-so-biodegradable...

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. The correlation between the sediment organic carbon and COD was investigated using sediments sampled in the middle Yellow River, China. Partitioning of the sediment organic carbon between the water and sediment phases was also...

By Patel, Jignesh; Nakhla, George ABSTRACT: The performance of an innovative membrane bioreactor (MBR) process using anoxic phosphorus uptake with nitrification and denitrification for the treatment of municipal wastewater with respect to operational performance and effluent quality is addressed in this paper. The system was operated at steady-state conditions with a synthetic acetate-based wastewater at a hydraulic retention time (HRT) of 12 hours and on degritted municipal wastewater at...
