Performance of high-loaded ANAMMOX UASB reactors containing granular sludge
Chong-Jian Tang,Ping Zheng,Caihua Wang,Qaisar Mahmood,Jiqiang Zhang,Xiao-Guang Chen,Lei Zhang,Jianwei Chen +7 more
TL;DR: A super high-rate performance with nitrogen removal rate (NRR) of 74.3-76.7 kg-N m(-3) day(-1) was accomplished in the lab-scale ANAMMOX UASB reactors, which was 3 times of the highest reported value.
Journal ArticleDOI
Waste biomass adsorbents for copper removal from industrial wastewater--a review.
Muhammad Bilal,Jehanzeb Ali Shah,Tayyab Ashfaq,Syed Mubashar Hussain Gardazi,Adnan Ahmad Tahir,Arshid Pervez,Hajira Haroon,Qaisar Mahmood +7 more
TL;DR: The current review is dedicated to presenting state of the art knowledge on various bioadsorbents and physico-chemical conditions used to remediate Cu(2+) from waste streams and the data of Cu removal was found best fit both Freundlich and Langmuir models.
Journal ArticleDOI
Microbial ecology of anaerobic digesters: the key players of anaerobiosis.
TL;DR: The cellulosic microorganisms, structure of cellulose, inoculum to substrate ratio, and source of inoculum and its effect on methanogenesis are highlighted and molecular techniques such as DGGE and FISH that deal with taxonomy and interaction and distribution of tropic groups used are discussed.
Journal ArticleDOI
Assessing potential dietary toxicity of heavy metals in selected vegetables and food crops
TL;DR: The phytotoxic effects and bioaccumulation of heavy metals in vegetables and food crops is reviewed and soil heavy metal thresholds for potential dietary toxicity are assessed.
Journal ArticleDOI
Effect of Pb toxicity on leaf growth, physiology and ultrastructure in the two ecotypes of Elsholtzia argyi.
Ejazul Islam,Dan Liu,Tingqiang Li,Xiaoe Yang,Xiaofen Jin,Qaisar Mahmood,Shengke Tian,Junying Li +7 more
TL;DR: Leaf ultrastructural analysis of the spongy mesophyll cells revealed that the excessive Pb concentrations caused adverse effects on chloroplast ultrastructure of both ecotypes whereby internal damage was more severe in NME.
