In developing countries, good-quality water is contaminated due to the disposal of untreated municipal and industrial wastewater (WW) into natural water reservoirs. Most of the wastewater is not treated properly according to international standards, and usually is disposed of and/or utilized for irrigation without appropriate treatment. The main hurdles in providing wastewater treatment (WWT) in developing countries include high costs, and the poor design, installation, and operation of conventional WWT systems. Therefore, the present study explores the maize cobs trickling filter-based (MCTF) low-cost WWT option for developing countries like Pakistan, India, and Bangladesh. In this regard, indigenous media trickling filter was designed and developed using maize cobs as packing material for biofilm growth. The MCTF-WWT system was continually operated and monitored for six months at constant hydraulic wastewater loading of about 113 +/- 2 m(3) per m(2) per day. The experimental data covers winter and summer seasons with temperature variations from 23 degrees C to 43 degrees C. System performance was evaluated by means of various WWT parameters, including biological and chemical oxygen demands (BOD5 and COD), total suspended and dissolved solids (TSS and TDS), turbidity, and color - before and after WWT. Experimental results showed that the MCTF-WWT system successfully removed about 79% BOD and 75% COD on average. The key reason for effective BOD and COD removal was rapid development of microbial film (within the first two weeks). Furthermore, the MCTF-WWT system removed 42-46% TSS, 28-30% TDS, 43-46% turbidity, and 33-37% color. The study concludes that the MCTF-WWT system is an effective and economical WWT option for irrigation/agricultural applications in developing countries.

Modeling the water quality in Ulubat Lake
Yenilmez, Firdes; Aksoy, Ayşegül; Department of Environmental Engineering (2007)
Lakes can be used for recreational purposes, agricultural irrigation, domestic water supply or industrial use. However, these functions of the lakes can be impaired due to excess nutrient loadings from industrial facilities, agricultural activities, and discharge of wastewaters from sewage systems. Uluabat Lake is one of the important lakes in Turkey faced with water quality problems due to excess nutrient loading from point and non-point sources. In this study, Water Quality Analysis Simulation Program (WA...
Rapid and Concomitant Analysis. of Pharmaceuticals in Treated Wastewater by Coated Blade Spray Mass Spectrometry
Poole, Justen J.; Gomez-Rios, German A.; Boyacı, Ezel; Reyes-Garces, Nathaly; Pawliszyn, Janusz (American Chemical Society (ACS), 2017-11-07)
The widespread use of pharmaceuticals in both human and animal populations, and the resultant contamination of surface waters from the outflow of water treatment facilities is an issue of growing concern. This has raised the need for analytical methods that can both perform rapid sample analysis and overcome the limitations of conventional analysis procedures, such as multistep workflows and tedious procedures. Coated blade spray (CBS) is a solid-phase microextraction based technique that enables the direct...
Assessment of PCB contamination, the potential for in situ microbial dechlorination and natural attenuation in an urban watershed at the East Coast of the United States
Kaya, Devrim; Sowers, Kevin R.; Demirtepe, Hale; Stiell, Brian; Baker, Joel E.; İmamoğlu, İpek; Kjellerup, Birthe (Elsevier BV, 2019-09-15)
Sediment contamination is a major environmental issue in many urban watersheds and coastal areas due to the potential toxic effects of contaminants on biota and human health. Characterizing and delineating areas of sediment contamination and toxicity are important goals of coastal resource management in terms of ecological and economical perspectives. Core and surficial sediment samples were collected from an industrialized urban watershed at the East Coast of the United Stated and analyzed to evaluate the ...
Modeling natural attenuation of petroleum hydrocarbons (btex) in heterogeneous aquifers
Uçankuş, Tuğba; Ünlü, Kahraman; Department of Environmental Engineering (2005)
Natural Attenuation can be an effective cleanup option for remediation of Groundwater contamination by BTEX. One of the important aspects of the methodology that has been recognized recently is that mass removal rates, the most important parameters used to determine effectiveness of the methodology, is controlled by groundwater flow regime, which to a large extent controlled by aquifer heterogeneity. Considering this recognition, the primary objective of this research is to quantitatively describe the relat...
Whole-cell fluorescent bacterial bioreporter for arsenic detection in water
Elcin, E.; Oktem, H. A. (Springer Science and Business Media LLC, 2019-10-01)
Microbial whole-cell bioreporters have been developed for environmental monitoring of arsenic contamination. Despite the great interest in bacterial bioreporters for arsenite detection, relatively few studies reported their response to arsenate levels. In this study, green fluorescent protein-based whole-cell Escherichia coli bioreporter was constructed for the measurement of both bioavailable arsenite and arsenate in water. The developed bacterial bioreporter has much higher sensitivity toward arsenate in ...
