Effluent standards system for industrial point sources in USA and its implimentation to China
Environmental Pollution & Control, 2014Co-Authors: Song GuojuAbstract:This article introduced the system of industrial point sources' water pollutant emission standards in American,including the role and goal of Effluent Limitation guideline,pollution source category and the corresponding technical standards,as well as the statutory foundation for Effluent guidelines(the determine procedure of the technology-based Effluent Limitations and water quality-based Effluent Limitations in permit).According to the America's experience,it was found that the industrial point sources' Effluent standards have no obvious relationship with the receiving water body's water quality in China,so it was needed to distinguish the technology-based Effluent Limitation and water quality-based Effluent Limitation;Secondly,industrial Effluent standards lack pertinence and operability due to insufficient technical supports,the ministry of environmental protection should promulgate the water pollutant Effluent Limitation guidelines;Thirdly,the method of industrial water pollutant emission standards' implementation were scattered and weak in China,and the waste water discharge permit should be used as the core of water pollution prevention and control policy.

a study on the determination method of toc Effluent Limitation for public sewage treatment plants
Journal of Korean Society of Water and Wastewater, 2016Co-Authors: Donghwan Jeong, Yangseok Cho, Kyunghee Ahn, Hyenmi Chung, Hoowon Park, Hyunsang Shin, Jin Hur, Daeho HanAbstract:As the Enforcement Ordinance of Environmental Policy Act was revised in 2013, total organic carbon(TOC) was added as an indicative parameter for organic matter in Water and Aquatic Ecosystem Environmental Criteria. Under these imminent circumstances, a regulatory standard is needed to achieve the proposed TOC Limitation control water quality from the public sewage treatment plants(PSTWs). This study purposes to present the determination method for TOC Effluent Limitation at the PSTWs. Therefore we investigate the TOC Effluent Limitation of foreign countries such as EU, Germany and USA, and analyse the Effluent water qualities of PSTWs. In using these TOC data, we review apprehensively the statistics-based, the technology-based, and the region(water quality)-based determination method of TOC Effluent Limitation for PSTWs.

a study on determination method of the compliance concentration of Effluent Limitation from public sewage treatment works in the jinwee stream watershed sewer system
Journal of Korean Society of Water and Wastewater, 2015Co-Authors: Donghwan Jeong, Yangseok Cho, Kyunghee Ahn, Hyenmi Chung, Young Seok Kim, Oh Sang KwonAbstract:In accordance with the Watershed Sewer System Maintenance Plan enforced on February 2, 2013, the different compliance concentration of Effluent limit be applied to Effluent discharged from public sewage treatment works(PSTWs) in each watershed on the basis of water quality thereof. With the introduction of watershed sewer system, it is necessary to set the compliance concentration of Effluent limit for PSTWs situated in the watershed, by region and PSTW size, to achieve water quality criteria for regional watersheds or target water quality under TMDL program. Watershed Environmental Agencies establish the Watershed Sewer System Maintenance Plan and set the compliance concentrations of Effluent limit for PSTWs under the plan. The agencies plan to apply tougher Effluent BOD concentration limits in Class I to IV areas. Effluent BOD concentration limits will be toughened from 5~10 mg/L to 3 mg/L in class II~III areas, from 10mg/L to 5mg/L in class IV areas. Uniform application of Effluent BOD concentration limits to PSTWs in the watershed sewer system need to be complemented considering type of sewage treatment technology employed and watershed characteristics. Therefore, this study presents method to determine the compliance concentration of Effluent limit from PSTWs in the watershed.

a study on the determination of formaldehyde Effluent Limitation in the industrial wastewater
Journal of Environmental Impact Assessment, 2013Co-Authors: Donghwan Jeong, Jaehoon Kim, Jinsoo Shin, Yongseok Kim, Kisik Shin, Doughee RhewAbstract:This study looked at how to establish Effluent Limitation standards for formaldehyde, a toxic chemical widely used in industries. To this end, we reviewed Water Quality Based Effluent Limitation (WQBEL), Technology Based Effluent Limitation (TBEL), and water quality criteria for protection of human health and aquatic organism. Based on the results, we estimated formaldehyde Effluent Limitation standards appropriate to control water quality of industrial wastewater in Korea. However, this study has limits due to the lack of some data necessary in estimating formaldehyde Effluent Limitation. For example, although water quality criteria based on non-carcinogenic properties of formaldehyde were calculated, those based on carcinogenic properties were not be able to estimate because of the absence of applicable cancer potency factor q1. Without applicable factor, we calculated water quality standards for formaldehyde based on water quality criteria of advanced countries including the United States, while with no water quality standard we referred to applicable drinking water quality standards of other countries. For eco-toxicity based on water quality criteria, proper figures could not be calculated since there have been few reliable data.

Comparison of the Soil-Plant-Air-Water Model and the Iowa State University-Effluent Limitation Guidelines Model to Replicate Holding Basin Performance
2008 Providence Rhode Island June 29 - July 2 2008, 2013Co-Authors: Daniel S. Andersen, Robert T. Burns, Lara B. Moody, Matthew J. HelmersAbstract:In Iowa, all open beef feedlot operations over 1,000 head are required to have runoff control systems. Iowa regulations allow the use of vegetative treatment systems (VTS) on open beef feedlots that meet regulatory siting requirements. For a National Pollutant Discharge Elimination System (NPDES) permit, the runoff control performance of VTSs must meet or exceed the performance of traditional runoff containment basins as predicted by the Iowa State University-Effluent Limitations Guideline (ISU-ELG) model. The ISU-ELG model is based on a model developed by Koelliker in 1975 to predict the performance of a holding basin at controlling feedlot runoff. In this paper, the criterion used to determine if a particular day is a “dewatering day” is investigated to determine its effect on basin performance, for wetter areas in Iowa the number of drying days has a large effect on basin performance, where as for the drier northwest region of Iowa this effect is limited. This paper compares results from the ISU-ELG model to results obtained using the Soil-Plant-Air-Water (SPAW) model to simulate traditional feedlot runoff containment basin performance. The SPAW model uses a soil moisture criterion to determine if conditions are acceptable for land application of basin Effluent. The results show that the ISU-ELG model over-predicts performance of traditional containment systems in comparison to the SPAW model at all five locations investigated.

Comparison of the Iowa State University Effluent Limitation Guidelines Model with the Soil-Plant-Air-Water Model for Evaluating Containment Basin Performance
Transactions of the ASABE, 2013Co-Authors: Daniel S. Andersen, Robert T. Burns, Lara B. Moody, Matthew J. Helmers, Robert HortonAbstract:This article compares results from the Iowa State University Effluent Limitations Guidelines (ISU-ELG) model to results obtained using the Soil-Plant-Air-Water (SPAW) model to simulate feedlot runoff containment basin overflow volume. The objective was to verify that the ISU-ELG model was providing a reasonable prediction of basin overflow. The ISU-ELG model uses a set of guidelines to determine if land application is acceptable, whereas the SPAW model uses a soil moisture criterion. The criterion for determining if a particular day was suitable for land application of basin Effluent was investigated to determine the effect on basin overflow volumes. The results show that the ISU-ELG model overpredicted the percentage of feedlot runoff controlled in comparison to the SPAW model at all five locations investigated. For wetter areas in Iowa, the number of drying days had a large effect on basin overflow volumes, whereas for the drier northwest region of Iowa, this effect was limited. Possible methods of improving the ISU-ELG model predictions include adding a soil moisture accounting function to model moisture levels in the land application area or calibrating the number of drying days required before land application can commence. Alternatively, the SPAW model can be used, but this requires additional user inputs and increases complexity in modeling the runoff control system.
