Catalytic activation of peracetic acid to decompose micropollutants in water

Jeon S., Choi C., Choi A., Lee H., (Corresponding) Changseok H.

Topic:

1. WATER AND WASTEWATER TREATMENT AND REUSE

Acetaminophen (APAP), a widely used pharmaceutical, is frequently detected in aquatic environments due to its persistence and limited removal by conventional wastewater treatment processes. In this study, a peracetic acid (PAA) based advanced oxidation system was developed using magnetically...Read more

A Comparative Study of ED and BPED Technologies for Ammonia Recovery from Wastewater.

Jongtae L., Kyungeun H., Haesung L., Taekyung B., (Corresponding) Changseok H.

Topic:

1. WATER AND WASTEWATER TREATMENT AND REUSE

Ammonia is a common pollutant in wastewater, and its removal is essential to prevent environmental issues such as odors and eutrophication, which can harm aquatic ecosystems and human health. While traditional treatment methods are energy-intensive and costly, ammonia has garnered attention as a...Read more

Comparison of Ceftriaxone, Ofloxacin, and Metformin Adsorption onto Activated Carbon from Aqueous Solutions

Hanganu D., Favier L., Lutic D., (Corresponding) Harja M.

Topic:

1. WATER AND WASTEWATER TREATMENT AND REUSE

Pharmaceutical compounds have been widely identified as organic pollutants in wastewater with adverse effects on the environment. This paper focuses on three active substances: ceftriaxone, ofloxacin, and metformin. The main reason for the interest is their ability to be excreted 80-90%...Read more
