... membrane (NF90 from Dow-Filmtec). In particular, the limitations of the application of the model to relatively high feed concentration and different pH are discussed. The model parameters were obtained through direct fitting to the experimental results, rather than performing separate experiments fo ...

Microwave and conventional methods have been used to extract pectin from orange peels, with different extraction periods, different solvent pHs and different types of solvent systems. For microwave extraction, the greatest total amount of pectin yield was found to be 5.27% on a dry basis fo ...

... by reverse osmosis has shown that boron removal by this technique can be used effectively for the reduction of boron in groundwaters, particularly at pH > 9.5. In conclusion, it may be stated that generally, groundwaters of Nicosia contain boron in levels, which are toxic for boron sensitive crops.

... fouling than particles. This suggests that coagulation pretreatment should target the optimum removal of organics in membrane filtration. Coagulation pH was also found to be an important fouling parameter. The pH, when too low, degraded particle characteristics, which then led to more fouling. Th ...

The influence of particle shape, ζ-potential and size with change of pH and ionic strength on permeate flux during the microfiltration of model dispersions (two different china clays with mean particle sizes of 3.5 µ ...

... (SWC). The effectiveness of the prepared adsorbent has been studied as a function of agitation time, adsorbent dosage, initial dye concentration and pH. The removal of rhodamine-B by SWC followed second order kinetic model. The second order model best describes adsorption kinetic data. Adsorption dat ...

... for boron removal as the post-treatment in a desalination plant. Based on the batch tests, cotton demonstrated a good capacity of adsorption at a pH about 7. This capacity was found to increase with an increase of boron concentration; the maximum capacity is 11.3 mg/g. The linear Freundlic ...

... using ceramic membranes. It remained uncertain which one might be more important in determining the filtration flux. In this paper the influences of pH and ionic strength on ceramic microfiltration of TiO2 suspensions were studied. Special attention was given to the changes of the surface propertie ...

Portuguese breweries were used for the selective removal of Cu2+, Cd2+ and Pb2+ from aqueous solutions. One of the goals was to establish both the pH profiles for the removal of each metal ion (1.0 mM) and the effect on the biomass biosorption capacity of pH adjustment during the process. Th ...

... in total 92 wt.% microporous minerals (zeolite + mica + clays). Quartz and feldspars constitute the non-microporous minerals (8 wt.%). Acidic water (pH 5.5) from the Kokkinolakkas Stream and basic water (pH 9.5) from the Koronia Lake were treated with the Evros natural zeolite. An intense increase i ...
