2018 | Keywords Microbubbles; Nanobubbles,
Generation of nanobubbles by ceramic membrane filters: The dependence of bubble size and zeta potential on surface coating, pore size and injected gas pressure.
Generation of gaseous nanobubbles (NBs) by simple, efficient, and scalable methods is critical for industrialization and applications of nanobubbles. Traditional generation methods mainly rely on hydrodynamic, acoustic, particle, and optical cavitation. These NBs generation processes render issues such as high energy consumption, non- flexibility, and complexity. This research reported the investigations of the use of membranes to generate NBs in ... Read more

2017 | Keywords Bank filtration efficiency,
Review on river bank filtration as an in-situ water treatment process.
Surface and ground water are valuable sources for drinking water. Certain industrial, mining, and agricultural practices pollute these critical resources. Riverbank filtration (RBF) is a cost effective in-situ water treatment process, which removes suspended solids, organic and inorganic pollutants. The RBF process is defined as a natural filter of soils and aquifer sediments at the river site. In RBF, river ... Read more

Drinking water quality simulation in Almonsha distribution network.
Water quality in distribution systems has become a prominent issue in the study of water networks. This study concentrates on chlorine disinfection as an indicator of water quality. The model discussed in this work is based on laboratory and field collected data. The model is applied on a real network which exists in Almonsha city in Upper Egypt. The experimental ... Read more

| Keywords Nanobubbles,
Influences of Air, Oxygen, Nitrogen, and Carbon Dioxide Nanobubbles on Seed Germination and Plant Growth
Nanobubbles (NBs) hold promise in green and sustainable engineering applications in diverse fields (e.g., water/wastewater treatment, food processing, medical applications, and agriculture). This study investigated the effects of four types of NBs on seed germination and plant growth. Air, oxygen, nitrogen, and carbon dioxide NBs were generated and dispersed in tap water. Different plants, including lettuce, carrot, fava bean, and ... Read more
