In this study, a method that can simultaneously separate oil/water mixtures and water-in-oil emulsions were developed. Various substrates (synthetic polymers and stainless steel meshes) were coated by rough hydrophobic polymer films. The prepared material... see more

Water and oil emulsion formation is a natural process that takes place during oil recovery and processing. Heavy oils of Kazakhstan form highly stable oil emulsions mostly stabilized by a high content of asphaltenes, resins, and other surface-active compo... see more

Microfiltration membranes made from polytetrafluorethylene (PTFE) have been successfully used for the separation of oily waste waters by membrane coalescence, but filtration of the oily waste waters with high emulsifier content have not yet been investiga... see more

Nature-inspired technology has been investigated widely. Anti biofouling properties of fish scale has inpired to improve membrane performance. Biofouling affects an oil-water separation membrane. The bacterial, coagulant, and hydrophobic oils attach to th... see more

This paper investigates the permeability and separation performance of polyphenolic-amine coated PVDF membrane with hydrophilic (26.9 ± 5.6°) and underwater oleophobic (162.1 ± 5.1°) surface modification. Surface chemical structures, surface compositions ... see more

The purpose of this study is  to treat water from Gasing River, Banyuasin District, South Sumatera Province by using ceramic membrane to produce clean water. Also, this study is to analyze the performance of ceramic membranes in terms of its ability ... see more

In recent years most of the oil reserves discovered has been related to heavy oil reservoirs whose reserves are abundant but still show operational difficulties. This fact provoked great interest of the petroleum companies in developing new technologies f... see more

Abstract Citronella (Cymbopogon nardus L. Rendle) essential oil contains active compounds such as antioxidants and has the potential to be developed as a sunscreen. Nanoemulsion is a water and oil dispersion stabilized by a surfactant layer and has a... see more
