Crude oil desalter effluent from a Tehran oil refinery was treated by a hybrid UF/RO membrane separation process. Ultrafiltration (UF) was used primarily to remove the emulsified oil droplets followed by the removal of total dissolved solids (TDS) via reverse osmosis (RO). The UF membrane was a hydr

This work was carried out under the specific collaboration agreement between the Bhabha Atomic Research Centre (BARC) from India and the Commissariat à l’Energie Atomique (CEA) from France. This paper summarises first results of review and research on the possible extraction of uranium from the conc

Major sources of wastewater generated on land can benefit from, and often are in need of, processes for the complete recovery of water, having only solid by-products or waste for disposal. This applies to municipal and industrial wastewater and brackish water reverse osmosis (RO) plants and agricult

When chemical disinfection is applied before or after desalination systems, compounds may be formed that pose potential risks to the health of human and aquatic organisms or impact aesthetic quality of drinking water. The formation and speciation of disinfection by-products (DBPs) in desalination sy

The aim of this study was to examine the variation in treatment performance, regarding the main pollutant parameters, i.e. chemical oxygen demand (COD), total nitrogen (TN), nitrate-nitrogen (NO3-N) and ortho-phosphate (PO4-P), at two different depths and at the outlet of duplicated vertical subsurf

The alumina microfiltration(MF) membrane was modified with nanocrystalline TiO2 in the pore wall. The electrokinetic properties of unmodified and modified alumina membranes were characterized by streaming potential measurements during tangential filtration at various conditions of pH, ionic concentr

The main objective of this research was to evaluate the potential use of a bench-scale anaerobic sequencing batch biofilm reactor (ASBBR) containing mineral coal as inert support for removal of sulfide and organic matter effluents from an ASBBR (1.2 m3) utilized for treatment of sulfate-rich wastewa

Using air as a carrier gas is common in humidification–dehumidification desalination processes. A computer program was written using mass and energy balances for modeling the process behavior. The parameters considered in this work were inlet air and fresh water recycle temperatures, inlet air flow

In this study, adsorption of Cu(II) onto the five locally abundantly low-cost biosorbents (Laminaria japonica, P. yezoensis Ueda, rice bran, wheat bran and walnut hull) was investigated depending on initial solution pH, contact time, adsorbent concentration and reaction temperature. Cu(II) removal w

Digital textile printing (DTP) is considered as an environmentally benign process because its wastewater production is relatively small compared with the conventional textile printing system. DTP is usually practiced at building office in an urban area rather than in a textile industrial complex, so
