Separation of liquid–liquid emulsions is a challenging problem that has gained importance
with the development of unconventional oil resources. Large volumes of water contaminated …

While the world faces an increased scarcity in fresh water supply, it is of great importance
that water from industry and waste streams can be treated for re-use. One of the largest …

Oilfield produced water (OPW) is one of the most important by-products, resulting from oil
and gas exploration. The water contains a complex mixture of organic and inorganic …

Abstract Oil-in-water (O/W) emulsion is considered to be difficult to treat. In this work, a low-
cost multi-layer-structured mullite-titania composite ceramic hollow fiber microfiltration …

Increasing demand for oil and gas leads to the generation of substantial amount of produced
water, bringing about deleterious impacts on the environment. Direct-contact membrane …

Oil/water (O/W) emulsion stabilized by surfactants is the part of oily wastewater that is most
difficult to handle. Ceramic membrane ultrafiltration presently is an ideal process to treat O/W …

A coagulation-flotation method using an anionic surfactant, sodium dodecyl sulfate (SDS),
and a cationic polyelectrolyte, poly (allylamine hydrochloride)[PAH], was designed for rapid …

In this work, ceramic ultrafiltration membranes deposited with different metal oxides (ie,
TiO2, Fe2O3, MnO2, CuO, and CeO2) of around 10 nm in thickness and similar roughness …

Substantial quantities of produced water generated during the extraction of oil and gas from
unconventional reservoirs present significant environmental concern and increase the …

Abstract Treatment and management of produced water are of great significance but critical
challenges remain due to the huge quantity and complexity of the liquid waste. Here we …
