A novel method of latex wastewater treatment was developed based on in-situ hypochlorous acid generation. The hypochlorous acid was generated in an undivided electrolytic cell consisting of two sets of graphite as anode and stainless sheets as cathode. The generated hypochlorous acid served as an ox

Laboratory experiments were carried out to investigate electrocoagulation as electrodisinfection of artificial wastewater contaminated by no pathogenic Escherichia coli species in batch culture and two surface waters using three different electrodes. Aluminium electrodes were found most efficient in

This paper reports the removal of a basic dye (rhodamine-B) by the activated carbon prepared from Parthenium biomass by sulphuric acid treatment method (SWC). The effectiveness of the prepared adsorbent has been studied as a function of agitation time, adsorbent dosage, initial dye concentration and

The Calembo Company (seafood conditioning, Sfax, Tunisia) uses 50 m3/d of drilling water per ton of fish to condition cuttlefish before freezing. The water used is characterised by its high degree of hardness, high sulphate concentration and salinity (67 g.l!1). Consequently, generated effluents con

There is a strong need to look at various possible designs that can be implemented to improve the single slope solar still performance through increasing the production rate of distilled water. Design modifications were introduced to the conventional solar still, involving the installation of reflec

The dairy industry is among the most polluting of the food industries in volume in regard to its large water consumption. The present work was related to investigations about practices of water management of 11 dairy plants. Treatment of the process water produced in the starting, equilibrating, sto

The essential point for a successful seawater reverse osmosis (SWRO) plant is pretreatment that provides consistent and high-quality feed to SWRO membranes. Advances in membrane technology and increasing requirements on water quality have stimulated the use of ultrafiltration (UF) for SWRO pretreatm

Removal of hexavalent chromium (Cr+6) was carried out with different nanofiltration (NF) membranes for varying concentration and pH of the membrane feed solution. Two membranes were used for this investigation: one high rejection membrane (NFI) and the other a low rejection membrane (NFII). The perc

Single component adsorption of phenol and 2-, 3- and 4-nitrophenol from water was studied under dynamic column conditions by using a carboxymethyl diaminoethane sporopollenin in a cobalt ion-loaded form, Co(II)CDAE-S, as solid phase. Adsorption isotherm data were acquired by frontal analysis for fiv

The photocatalytic degradation of Brilliant Green (BG, Bis(4-diethylaminophenyl)phenylmethylium chloride), a cationic dye, was investigated in an irradiated TiO2 aqueous dispersion. In this study, in order to obtain a better understanding on the mechanistic details of this TiO2-assisted photodegrada
