Efficient Phosphorus Cycling in Food Production: Predicting the Phosphorus Fertilization Effect of Sludge from Chemical Wastewater Treatment

14-Jun-2016 | Anne Falk Øgaard; Eva Brod, Journal of Agricultural and Food Chemistry, 2016

This study examined the P fertilization effects of 11 sewage sludges obtained from sewage treated with Al and/or Fe salts to remove P by a pot experiment with ryegrass (Lolium multiflorum) and a nutrient-deficient sand–peat mixture. Also it investigated whether fertilization effects could be ...

IJERPH, Vol. 13, Pages 588: Antibiotics in Wastewater of a Rural and an Urban Hospital before and after Wastewater Treatment, and the Relationship with Antibiotic Use—A One Year Study from Vietnam

14-Jun-2016 | Lien, La Thi Quynh; Hoa, Nguyen Quynh; Chuc, Nguyen Thi Kim; Thoa, Nguyen Thi Minh; Phuc, Ho Dang; Diwan, Vishal ; D ..., International Journal of Environmental Research and Public Health, 2016

Hospital effluents represent an important source for the release of antibiotics and antibiotic resistant bacteria into the environment. This study aims to determine concentrations of various antibiotics in wastewater before and after wastewater treatment in a rural hospital (60 km from the center ...

Amphiphilic Poly(ether sulfone) Membranes for Oil/Water Separation: Effect of Sequence Structure of the Modifier

10-Jun-2016 | Guangfa Zhang, Jingxian Jiang, Qinghua Zhang, Xiaoli Zhan, Fengqiu Chen, AIChE Journal, 2016

Abstract Oil‐contaminated wastewater threatens our environment and health, thus novel membrane materials with low‐ or non‐fouling properties are an immediate need for oily wastewater treatment in a cost‐effective and environmentally friendly manner. In this study, three types of amphiphilic ...

Flocculation behavior of cationic pea starch prepared by the graft copolymerization of acrylamide for wastewater treatment

08-Jun-2016 | Yongqiang Zou, Shanshan Li, Yuqi Wang, Chenxi Yuan, Weijian Yuan, Lan Zheng, Xiaolong Han, Journal of Applied Polymer Science, 2016

ABSTRACT To improve the flocculation efficiency of coal mine wastewater treatment, we synthesized a cationic flocculant by grafting acrylamide (AM) onto pea starch, and we performed the characterization with elemental analysis, Fourier transform infrared spectrometry, scanning electron ...

rRNA Gene Expression of Abundant and Rare Activated-Sludge Microorganisms and Growth Rate Induced Micropollutant Removal

06-Jun-2016 | David C. Vuono; Julia Regnery; Dong Li; Zackary L. Jones; Ryan W. Holloway; Jörg E. Drewes, Environmental Science & Technology, 2016

The role of abundant and rare taxa in modulating the performance of wastewater-treatment systems is a critical component of making better predictions for enhanced functions such as micropollutant biotransformation. In this study, we compared 16S rRNA genes (rDNA) and rRNA gene expression of taxa ...

Mass Balance Assessment for Six Neonicotinoid Insecticides During Conventional Wastewater and Wetland Treatment: Nationwide Reconnaissance in United States Wastewater

03-Jun-2016 | Akash M. Sadaria; Samuel D. Supowit; Rolf U. Halden, Environmental Science & Technology, 2016

Occurrence and removal of six high-production high-volume neonicotinoids was investigated in 13 conventional wastewater treatment plants (WWTPs) and one engineered wetland. Flow-weighted daily composites were analyzed by isotope dilution liquid chromatography tandem mass spectrometry, revealing ...

To What Extent Can Full-Scale Wastewater Treatment Plant Effluent Influence the Occurrence of Silver-Based Nanoparticles in Surface Waters?

02-Jun-2016 | Lingxiangyu Li; Monika Stoiber; Andreas Wimmer; Zhenlan Xu; Claus Lindenblatt; Brigitte Helmreich; Michael Schuster, Environmental Science & Technology, 2016

Silver-based nanoparticles (Ag-b-NPs) emitted by wastewater treatment plants (WWTPs) are considered to be widely present in the natural environment. However, there is much that is unknown about the effect of WWTP effluent on the occurrence of Ag-b-NPs in surface waters. On the basis of field ...

Transport properties of small molecules in zwitterionic polymers

31-May-2016 | Shawreen Shah, Junyi Liu, Siucheung Ng, Shuangjiang Luo, Ruilan Guo, Chong Cheng, Haiqing Lin, Journal of Polymer Science Part B: Polymer Physics, 2016

ABSTRACT Despite great interests in using zwitterionic polymers for membrane surface modification to enhance antifouling properties, there lacks fundamental understanding of the relationship between polymer structure and water/salt separation properties. In this study, two series of ...

Sensors, Vol. 16, Pages 797: Characterisation of Phosphate Accumulating Organisms and Techniques for Polyphosphate Detection: A Review

31-May-2016 | Tarayre, Cédric ; Nguyen, Huu-Thanh ; Brognaux, Alison ; Delepierre, Anissa ; De Clercq, Lies ; Charlier, Raphaëlle ..., Sensors, 2016

Phosphate minerals have long been used for the production of phosphorus-based chemicals used in many economic sectors. However, these resources are not renewable and the natural phosphate stocks are decreasing. In this context, the research of new phosphate sources has become necessary. Many ...

Immobilization of Heavy Metals by Solidification/Stabilization of Co-Disposed Flue Gas Desulfurization Brine and Coal Fly Ash

26-May-2016 | Jay E. Renew; Ching-Hua Huang; Susan E. Burns; Maya Carrasquillo; Weiling Sun; Kirk M. Ellison, Energy & Fuels, 2016

The coal-fired power industry in the United States faces growing needs to improve wastewater treatment and disposal practices, especially for wet flue gas desulfurization (FGD) systems. Zero liquid discharge (ZLD) treatment systems may be implemented, and one ZLD option is the coupling of brine ...
