In winter in high-latitude oceans, there is a great amount of sea ice, which is being recognized as a new resource of fresh water. Different desalination methods including sea ice solid-state desalination and sea ice melt-water desalination were compared. In a centrifugal desalination experiment, ro

A new composite material able to remove hexavalent chromium [Cr(VI)] ions from aqueous solutions was obtained by reacting poly(4-vinylpyridine) (P4VP) with bentonite clay [Bf]. Two composite samples, Bf0.06 and Bf0.3, were prepared by varying initial amounts of P4VP. Thermogravimetric analysis revea

The process, called electrodeposition, was used for recovery of metals from aqueous solutions. The aqueous solutions of the sulfate forms of copper and cobalt metals were used as the catholyte solution and 0.1 M NaNO3 was used as an anolyte solution. The effect of current density, metal concentratio

The effect of backwash frequency (15, 30 and 60 min) and influent flux (3.75, 7.50 and 11.25 L/h/m2) on fouling amelioration in an innovative external side-stream dead-end microfiltration anaerobic membrane bioreactor (AnMBR) for the treatment of domestic wastewater at 25EC was investigated. During

This paper quantifies the influence of operating conditions on the efficiency of domestic wastewater treatment and of membrane bioreactors (MBR) performance with a statistical method (multivariate linear regression model). The impact of the following seven parameters—(1) transmembrane pressure (TMP)

We have developed a method for the calculation of contact angle of spherical particle in interaction with a bubble in the process of flotation. The balance of forces acting on the instantaneous TPC perimeter in the radial direction could connect the central angle α and the contact angle θ in only on

A three-stage submerged MBR was operated under a prolonged SRT condition—more than 800 days—to treat high strength industrial wastewater. Throughout the entire experiment, chemical and biological effects on sludge production and nitrification/denitrification were investigated. The trend of MLSS grow

Bisphenol A (BPA)-imprinted polysulfone (PSf) particles for the binding and recognition of BPA were prepared by means of a phase inversion technique. The porosity of the PSf particles was about 70%. Binding and recognition of BPA for the particles were investigated; the binding amounts increased ver

The transport of cationic dyes methyl violet and rhodamine B from aqueous synthetic dye solution through flat type supported liquid membranes (SLM) using di (2-ethylhexyl) phosphoric acid (D2EHPA) as carrier was studied and the parameters affecting the dyes transport were determined. The extraction

Poly(ethylene glycol) acrylates (PEGA) containing double-bond in the molecular chain end were synthesized via the esterification of poly(ethylene glycol) (PEG) with acrylate acid in aid of the catalysis of p-toluenesulfonic acid. Then hydrophilic modification of poly(phthalazine ether sulfone ketone
