Quality and management of wastewater in sugar industrySpringer Science and Business Media LLC - Tập 7 - Trang 461-468 - 2015
Pradeep Kumar Poddar, Omprakash Sahu
Wastewater from sugar industries is one that has complex characteristics and is considered a challenge for environmental engineers in terms of treatment as well as utilization. Before treatment and recycling, determination of physicochemical parameter is an important mechanism. Many different types of techniques are introduced and modified for the purpose, but depend upon the water quality paramet...... hiện toàn bộ
Numerical investigation of granular filter under the bed of a canalSpringer Science and Business Media LLC - Tập 9 - Trang 1-15 - 2019
Fatemeh Jafari, Farzin Salmasi, John Abraham
To protect canal beds against erosion and to prevent seepage from the bottom or side of a canal, impermeable linings are often used. These linings can suffer from several problems including damage due to uplift pressure when the groundwater table is high. Thus, it is necessary to provide a drainage system under the hard lining of the canal to reduce the water pressure, especially at the end of the...... hiện toàn bộ
Numerical simulation of seepage problem in porous mediaSpringer Science and Business Media LLC - Tập 9 - Trang 1-8 - 2019
E. Fadaei-Kermani, S. Shojaee, R. Memarzadeh, G. A. Barani
In the paper, a mesh-free method called smoothed particle hydrodynamics (SPH) is presented to deal with seepage problem in porous media. In the SPH method, the computational domain is discredited by means of some nodes, and there is no need for computational domain meshing. Therefore, it can be said that it is a truly mesh-free approach. The method has been applied to analyze seepage problem in ea...... hiện toàn bộ
On using clay and nanoclay ceramic granules in reducing lead, arsenic, nitrate, and turbidity from waterSpringer Science and Business Media LLC - Tập 8 - Trang 1-6 - 2018
Parisa Rezvani, Mohammad Mehdi Taghizadeh
New technology has provided a cheap and abundant access to nanoclay which has more prominent and efficient properties than clay. The aim of this research was a performance review of clay and nanoclay granules for the purpose of improving physicochemical as well as biological quality of water. To this end, clay granules and a 50% composition of clay and nanoclay with an average of a 5-mm diameter w...... hiện toàn bộ
Pesticide residues analysis in water samples of Nagarpur and Saturia Upazila, BangladeshSpringer Science and Business Media LLC - Tập 8 - Trang 1-6 - 2018
M. Hasanuzzaman, M. A. Rahman, M. S. Islam, M. A. Salam, M. R. Nabi
Pesticides used to protect the crops from pest attack in the agricultural fields pose harmful effect to the non-target organisms such as human and many other aquatic and terrestrial organisms either directly or indirectly through food chain. The present study was conducted to monitor a total of seven pesticide residues under organochlorine, organophosphorus and carbamate pesticides in three differ...... hiện toàn bộ
Performance assessment of a pilot-size vacuum rotation membrane bioreactor treating urban wastewaterSpringer Science and Business Media LLC - Tập 1 - Trang 103-110 - 2011
Raafat Alnaizy, Ahmad Aidan, Haonan Luo
This study investigated the suitability and performance of a pilot-scale membrane bioreactor (MBR). Huber vacuum rotation membrane (VRM 20/36) bioreactor was installed at the Sharjah sewage treatment plant (STP) in the United Arab Emirate for 12 months. The submerged membranes were flat sheets with a pore size of 0.038 μm. The VRM bioreactor provided a final effluent of very high quality. The aver...... hiện toàn bộ
Graph attention neural network for water network partitioningSpringer Science and Business Media LLC - - 2023
Kezhen Rong, Minglei Fu, Yunjie Huang, Ming Zhang, Lejin Zheng, Jianfeng Zheng, Miklas Scholz, Zaher Mundher Yaseen
AbstractPartitioning a water distribution network into several district metered areas is beneficial for its management. Partitioning a network according to its node features and connections remains a challenge. A recent study has realized water network partitioning based on node features or pipe connections individually. This study proposes an unsupervised clusteri...... hiện toàn bộ
