Performance Evaluation of the Coagulation and Flocculation Process in Removing Pollutants from textile Dyeing Factory Wastewater
Background and Objective: In this research, the performance of coagulation and flocculation process for the removal of pollutants from raw wastewater as well as anaerobic unit effluent of biological treatment of textile dyeing factory wastewater treatment plant was investigated. Methods: For this purpose, the Jar test unit as a batch reactor, FeCl3, PAC, and Alum as coagulants, and two polyelec...
متن کاملImmobilized microalgae for removing pollutants: review of practical aspects.
This review analyzes the state-of-the-art of a specific niche in biological wastewater treatment that uses immobilized eukaryotic microalgae (and several prokaryotic photosynthetic cyanobacteria), with emphasis on removing nutrients with the support of microalgae growth-promoting bacteria. Removal of other pollutants by this technology, such as heavy metals and industrial pollutants, and techni...
متن کاملThe Potential Applications of Using Compost Chars for Removing Environmenal Pollutants from Solution
Municipal compost sample was pyrolyzed to produce compost char as a sorbent for removing the herbicide atrazine from solution. The compost-based char was compared with an activated carbon derived from corn stillage. When compost was pyrolyzed, the char yield was greater than 45% when heated under air, and 52% when heated under N2. In contrast, when the corn stillage was pyrolyzed under N2, the ...
متن کاملThe release of pollutants from roofing materials in laboratory experiments
Diffuse pollution sources have been recognised by the European Water Framework Directive to significantly contribute to pollution of stormwater receivers. Stormwater runoff is considered to represent diffuse pollution sources. The aim of this study was to clarify the contributions of specific sources in the urban environment to the content of organic and inorganic pollutants in stormwater. This...
متن کاملAn Enhanced Median Filter for Removing Noise from MR Images
In this paper, a novel decision based median (DBM) filter for enhancing MR images has been proposed. The method is based on eliminating impulse noise from MR images. A median-based method to remove impulse noise from digital MR images has been developed. Each pixel is leveled from black to white like gray-level. The method is adjusted in order to decide whether the median operation can be appli...
