Pollutant Removals according to Media Type at the Filtration Unit with the Circulation of Suspended Media
The removal efficiencies of SS, T-P, CODmn and T-N were examined using a filtration unit with the circulation of the suspended media. The removal efficiencies of SS, T-P, CODmn and T-N were 90%, 74%, 89% and 15%, respectively, when the circulation rate of the media was 20% of th...

Development of Low Basicity Aluminum Coagulants for Improving Coagulation Efficiency
In this study, we have developed a low basicity PACl coagulants containing iron by changing the basicity of the existing PACl and using iron salt coagulant as an additive for effective coagulation. The analysis of Al(Ⅲ) hydrolysis species with low basicity PAIC showed that mono...

A Study on Membrane Fouling Control by Immobilized Microbial Media for Nitrification in Membrane Bioreactor
In order to control membrane fouling in the MBR process, energy consumption by membrane cleaning is high as critical flux down operation, influent pre-treatment, and membrane cleaning (air cleaning, back washing, chemical cleaning) needs to be taken to control membrane fouling a...

Study on the Quantitative Analysis of Styrene Oligomers Originated from Styrene-based Plastic Polymer Materials
Plastic pollution is an important issue in the environment. However, there are few systematic studies on the harmful substances that can be leached out from plastics. The objective of this study is to improve a method for monitoring various styrene oligomers (SOs) derived from p...
