• Two strategies for phosphorus removal from reject water of municipal wastewater treatment plant using alum sludge 

  Yang, Y. ; Zhao, Y.Q. ; Babatunde, A.O. ; Kearney, P. (IWA Publishing, 2009-12)

  In view of the well recognized need of reject water treatment in MWWTP (municipal wastewater treatment plant), this paper outlines two strategies for P removal from reject water using alum sludge, which is produced as ...
• A promising approach of reject water treatment using a tidal flow constructed wetland system employing alum sludge as main substrate 

  Yang, Y. ; Zhao, Y.Q. ; Wang, S.P. ; Guo, X.C. ; Ren, Y.X. ; Wang, L. ; Wang, X.C. (IWA Publishing, 2011-06)

  This study examined a novel reuse of the alum sludge, an inescapable by-product of the production of drinking water when aluminium salt is added as a coagulant, as the main medium in a laboratory-scale multi-stage constructed ...
• Co-conditioning of the anaerobic digested sludge of a municipal wastewater treatment plant with alum sludge : benefit of phosphorus reduction in reject water 

  Yang, Y. ; Zhao, Y.Q. ; Babatunde, A.O. ; Kearney, P. (Water Environment Federation, 2007-12)

  In this study, alum sludge was introduced into co-conditioning and dewatering with an anaerobic digested activated sludge to examine the role of the alum sludge in improving the dewaterbility of the mixed sludge and also ...

• Fuzzy synthetic evaluation of Weihe water quality 

  Geng, Yani ; Zhang, Jun ; Zhou, Qi ; Xu, Chundi ; Zhao, Y.Q. (Editura EcoZone, 2011-10)

  Based on the fuzzy logic principle, a modified Fuzzy Synthetic Evaluation (FSE) is proposed to assess water quality status of Weihe River (Baoji, China). The potential application of the FSE has been tested in a case study. ...
