Korean Water and Wastewater Works Association (KWWA) Profile
Korea Water and Wastewater Works Association (KWWA) was founded in 21st/Jan/2002 based on Article 39 of Water Supply Law, for the stable reservation and supply of clean water, which is one of the most important factors for the improvement of the quality of life. KWWA, aiming for the healthy development and supply of the waterworks, contributes to the qualitative improvement in public life, the
Up until the 1970s, the water quality in South Korea was subpar due to the lack of a managed sewerage system and overall poor water management services. Past reports made by the Korean Journal of Parasitology found that more than 84 percent of fecal samples were contaminated with helminth, which is a dangerous parasitic worm that can lead to

- What is modified polyacrylamide drilling fluid?
- Indeed, modified polyacrylamide drilling fluid has been proven to be of great interest for use in the construction of bored piles and diaphragm walls in recent years. 1. Introduction Drilling fluid is a critical component in exploration and excavation, classified into water-based, oil-based, synthetic-based, and gas-based.
- Does barite/polyacrylamide nanocomposite affect water-based drilling fluid?
- Roodbari and Sabbaghi (2021) studied the effect of barite/polyacrylamide nanocomposite in the water-based drilling fluid, which showed the incline of its fluid viscosity and the reduction of fluid loss and filter cake thickness. Besides, Kuma et al. (2025) optimised the polyacrylamide-based drilling fluid with the inclusion of hematite.
- Is cationic polyacrylamide a good fluid additive?
- It is recommended to use anionic polyacrylamide because of its minimal interaction and also compatibility with other fluid additives. Due to the cationic polyacrylamides interacting strongly with shale, it can potentially cause formation damage. Both the rheological studies and the zeta potential tests gave the same results.
- Can cationic-surfactant polyacrylamide be used as a viscosifier in drilling fluid?
- Likewise, Shettigar et al. (2018) designed a cationic-surfactant polyacrylamide as viscosifier in drilling fluid, which showed the improvement of rheology and cutting effect due to the hydrophobic and electrostatic interaction between the surfactant (cetyltrimethyl ammonium bromide) and polymer.
