The Cost

Very few studies have investigated the adsorption performance of hydrophobic and hydrophilic silicas with dissolved organics in water, which is a required final step during produced water treatment. The cost of functionalization also hinders the use of hydrophobic materials as sorbents. Novel hydrophilic silicas, prepared at low temperature and ambient pressure, were characterised by SEM, FTIR and BET analysis, and studied for the adsorption of aqueous phase organic compounds at concentrations below their solubility limits. Adsorption capacities were found to be up to 264 mg/g for benzene and 78.8 mg/g for toluene. Direct comparison is made with the analogous hydrophobic version of one of the silica materials, demonstrating comparable uptakes for benzene concentrations lower than 50 mg/L. This finding supports the hypothesis that, at very low aqueous phase organic concentrations, hydrophobicization has no discernible effect on access of the pollutants to the internal porosity of the material.

Anode Substrate

The voltage is the critical electrochemical parameter in microbial fuel cells (MFCs).There are three major oilfield wastewaters including water flooding produced water, polymer flooding produced water and ASP flooding produced water. These three wastewaters were used as anode substrate of three MFCs in this study. The influence and the influencing factors of the output voltage of the three MFCs and the produced water main refractory organics removal effect were studied. The results show that During this reaction period, MFCs cathode potential stays relative stable, however, anode potential shows a remarkable increasing trend, thus, the anode contributes mostly to the change in output voltage. COD removal effect of Anode substrate and the coulombic efficiency are both influencing factors of the anode potential .The microbial fuel cell for wastewater of surfactant, remove the best effect;For different produced water, oil and polymer removal effect abide by the MFC output voltage and COD value changing law.

To improve the organics removal efficiency of surface water treatment technologies, powdered activated carbon (PAC) has often been added. Some of the PAC particles with the dissolved organics already adsorbed are present in the form of a colloidal quasi-colloidal dispersion and can be removed most efficiently by coagulating and flocculating them together with the natural suspended solids. This, however, cannot be accomplished unless the PAC is added 3-5 minutes ahead under violent stirring of the water to be treated. Laboratory data demonstrated that the PAC and the Al-hydroxides formed of the coagulant (Al-salt) added remove different types of organics from the water and consequently do not compete with each other.

Solids Separation

Solids separation, adsorption onto participates and volatilization are the main physico-chemical mechanisms responsible for the removal of organic matter in wastewater treatment plants. In addition, solids separation as well as adsorption performance may be enhanced by chemical flocculation/precipitation with hydrolyzing metal salts. With the help of particle size distributions and other characteristics of the particulates at different treatment stages, more insight can be gained into the interactions between paniculate properties and solids separation performance. Significant removal of trace organics is achieved by adsorption onto paniculate surfaces and stripping in aeration tanks. Examples illustrate the adsorption of the relatively large quantities of substances contained in detergents and reveal the effect on water and sludge quality. Octanol/water partition coefficients of trace organics may be used together with oxygen transfer characteristics to determine the potential of volatilization into the air. The effect of flocculants on paniculate and dissolved organics removal in wastewater treatment is illustrated when Fe-salts are dosed to raw sewage, to the biological stage or to tertiary filters.
