  author={Hae-Ryong Jung and U Kim and Gyu Tae Seo and Hyun Dong Lee and Chun-Sik Lee},
  journal={Environmental Engineering Research},
A series of laboratory-scale corrosion experiments was carried out to observe the effect of dissolved oxygen (DO) in the presence of other water quality parameters, such as hardness, Cl - , and pH using various pipe materials. In addition, a simulated loop system was installed at a water treatment plant for pilot-scale experiment. Laboratory-scale experiment showed that corrosion rates for galvanized steel pipe (GSP), carbon steel pipe (CSP), and ductile cast iron pipe (DCIP) were decreased to…

The corrosion performance of fairly new generation of micro-alloyed steels was compared in different concentrations of aerated and deaerated brines. Electrochemical polarization, weight loss and


The formation of scale in water distribution networks is a significant technical, aesthetic and hygienic problem. The usage of different types of pipes has increased abundantly in various fluid flow

Effects of advanced treatments using granular activated carbon adsorption with ozonation and ultrafiltration on chlorine decay

AbstractThe application of advanced treatment processes has been substantially increased to comply with regulations on microbial inactivation and disinfection by-products. The advanced processes,

Distribution system water age can create premise plumbing corrosion hotspots

Examination of lead pipe, copper pipe with lead solder, and leaded brass materials in a replicated lab rig simulating premise plumbing stagnation events indicated that lead or copper release could increase as much as ∼440 % or decrease asmuch as 98 % relative to water treatment plant effluent.

Quantification of corrosion inhibitors used in the water industry for steam condensate treatment: the indirect electroanalytical sensing of morpholine and cyclohexylamine

Corrosion inhibitors are widely used in the water industry for steam condensate treatment. Due to their application into the food industry, the Food and Drug Administration (FDA) legislate that such

Assessment of the corrosiveness of the water in the distribution line from intake to consumer outlets in Malawi

A study was carried out to assess the water quality in the distribution pipes in Malawi. In particular the study was aimed at testing the corrosiveness of the water using the Langelier Saturation
