Research Abstracts

Membrane separation processes have become an emerging technology for the treatment of oily wastewater due to high oil removal efficiency and relatively facile operational process. This review will highlight the recent development of advanced membrane technology such as surface modification, addition o

Membrane distillation (MD) has gained significant regard from industrial and academic perspective in recent years, thus the frequency of publications related to the field has greatly accelerated. New perspectives have boosted the research activities related to deeper understanding of heat and mass tra

A new RO system for large-scaled SWRO plant has been developed in the project named “Mega-ton Water System” with private–public cooperation in Japan. The characteristic of the newly developed RO system to increase the recovery rate is to use the short vessel that contains 2–4 elements for the first s

• Life cycle assessment of engineered osmosis and osmotic dilution are performed • Environmental impacts of forward osmosis can be competitive with deep well disposal • The cost of FO can be significantly lower (up to 60%) than deep well disposal • FO energy demand with no upstream pretreatment is a

This study investigated an integrated process to treat the wastewater from an instant tea powder factory. The wastewater was pretreated by combination of coagulation–flocculation. Polyaluminum ferric chloride (PAFC) was used as the coagulating agent. The optimum operating conditions with respect to c

• New method for Li recovery from seawater is proposed using the world-first dialysis. • Li ionic superconductor as the Li separation membrane (LISM) was used. • Only Li ions can permeate the LISM. • The Li recovery ratios to approximately 7% after 72 h with no electrical supply. • Li separation proc

• Low cost pretreatment for RO brine recovery using inline coagulation-UF method. • Outstanding performance of FeCl3 in foulant removal compared to PACl and ACH. • 55% and N99% of DOC and phosphate removed when FeCl3 was used as the coagulant. • Highest removal of humic substances, building blocks a

Highly concentrated NaCl, KCl, MgCl2 and MgSO4 solutions were treated using DCMD. The effects of salt concentration (1.0–4.0 mol/L) and circulation velocity (0.1–0.5 m/s), as well as thermodynamic and physical properties of the salt solutions on permeate flux were investigated. Results showed that th

Reverse osmosis (RO) has been proved to be an effective technology in the treatment of low level radioactive wastewaters (LLRWs) in nuclear power plants (NPPs). However, particular attention must be paid to any possible negative influence of excessive boron on the performance of membrane units. In th

A dynamic membrane/electrocoagulation hybrid system, with precoating of a microfiltration ceramic membrane using Kaolin clay, was investigated with respect to membrane fouling mitigation and oil removal during the treatment of oily wastewater. The performances between the ceramic membrane and dynamic
