... areas of focus in these studies is the use of membranes in microfiltration, ultrafiltration and nanofiltration. In this report the humic acid removal efficiency of ultrafiltration membranes with 3 kDa, 5 kDa and 10 kDa MWCO is examined. The membranes were made of regenerated cellulose and wer ...

... from an initial 2.4 g/L to 21 g/L. The plant consistently produced fully nitrified effluents when DO was kept over 2.0 mg/L. Over 99.99% BOD5 removal and 95% COD removals were achieved in the system. When DO concentration was 2 mg/L and mixed liquor suspended solids, MLSS, concentration was 16 ...

Studies of removal of platinum (IV) ion microquantities from the model chloride solutions on the ion exchangers of the functional quaternary ammonium groups
... have been widely applied in industry. The recovery of noble metals from industrial wastes becomes an economic issue. The laboratory studies of removal of platinum (IV) microquantities from 0.1–6M hydrochloric acid solutions on the ion-exchangers of the functional quaternary ammonium group ...

Removal of reactive dye from aqueous solutions by adsorption onto activated carbons prepared from sugarcane bagasse pith
... followed by pyrolysis at 600°C and by physical activation at 600°C in absence of air (AC3). Different activated carbons have been used for the removal of reactive orange (RO) dye from aqueous solutions. Batch adsorption experiments were performed as a function of initial dye concentration ...

... that chromium concentration ranged from 1300–2500 mg Cr6+/l, while NaCl concentration varies from 40000 to 50000 mg/l. The study of chromium removal efficiency by using of a pilot-scale setup of 7 and 16 bar RO membrane units at different working pressures and under variable salt concentration ...

... shaking condition by varying parameters such as initial Cr(VI) concentrations, adsorbent dosage, pH, temperature and eluting agent. Complete Cr(VI) removal was achieved at pH less than 2, initial Cr(VI) of 100 mg/L and RWS dosage of greater than 1.5 % (w/v). The point of zero charge (pHPZC) of 4.9 ...

... strongly influences the bioconversion of sugar containing hydrolysates. Previous investigators have used anion exchange resins for acetic acid removal from different hemicellulosic hydrolysates. In this study, the efficiency of an anion exchange membrane was compared to that of an anion exchang ...

Pilot plant investigation on petrochemical wastewater treatment for the removal of copper and chromium with the objective of reuse
... wastewater treatment. Lime is plentiful, inexpensive and readily available. Finally, the results show that filtration has a critical role in the removal of small flocks of heavy metal compounds that are not easily sedimented. Desalination 171 (2004) 85–93 Pilot plant investigation o ...

... membrane processes seem to be most useful for water treatment. Reverse osmosis, nanofiltration and ultrafiltration have been applied to phthalate removal from water. In the experiment three membranes RO-DS3SE were tested for reverse osmosis, membrane NF-DS5DK for nanofiltration and UF-DSGM fo ...
