TL;DR: This paper presents a review of the main sludge treatment techniques used as a pretreatment to anaerobic digestion, and it is likely that low impact pretreatment methods such as mechanical and thermal phased improve speed of degradation, while high impact methods improve both speed and extent of degradation.

TL;DR: It was found that PMS could be activated by some anions, but PS and H( 2)O(2) cannot, and the activation efficiencies of PMS are remarkable, whereas remarkable by HCO(3)(-), HPO(4)(2-), Cl(-) and CO(3)2-).

TL;DR: This study is a review of the recent literature on the use of natural and modified lignocellulosic residues for Cr adsorption and finds that many by-products of agriculture have proved to be suitable low cost adsorbents for Cr(VI) and Cr(III) removal from water.

TL;DR: The proposed electrode was successfully used as an indicator for potentiometric determination of Hg(II) in dental amalgam and water samples and the electrode has a short response time and can be used for at least 55 days without any considerable divergence in potentials.

TL;DR: Multivariate statistical analyses, principal component and cluster analyses, suggest that Mn, Zn, Pb and Ti are derived from anthropogenic sources, particularly coal mining activities, and the extreme proximal and distal parts are heavily contaminated with maximum heavy metals.

TL;DR: The values of pollution index and integrated pollution index indicated that metal pollution level was Pb>Cd>Zn>Cu, and Cd, Cu, Pb and Zn belong to moderate or high pollution level, and Shenyang was suffering from serious metal contamination.

TL;DR: Synthesized maghemite nanoparticles showed the highest adsorption capacities of CR compared to many other adsorbents and would be a good method to increase adsorbent efficiency for the removal of CR in a wastewater treatment process.

TL;DR: MOFs can be suggested as potential re-usable adsorbents to remove anionic dyes because of their high porosity, facile modification and ready re-activation.

TL;DR: It can be concluded that reusing the FCS as a low-cost material into the coagulation/flocculation process in wastewater treatment plants can offer some advantages such as high efficiency for AR119 dye removal and economic savings on overall treatment plant operation costs.

TL;DR: The BGAC was shown to be suitable adsorbent for adsorption of RB5 using fixed-bed adsorptive column and fitted well to the Thomas and Yoon-Nelson models with coefficients of correlation R(2)>or=0.93 at different conditions.

TL;DR: Thermodynamic parameters showed that the adsorption process was spontaneous, endothermic and chemical in nature, and the MNP-NH(2) sorbent was able to remove 98% of Cu(2+) from polluted river and tap water.

TL;DR: A set of universal procedures is brought forward, which is novel, tentative and adaptive to evaluate hyperaccumulators' feasibility before large-scale commercialization.

TL;DR: This paper presents the advantages and disadvantages of traditional sediment remediation techniques in use, such as dredging, capping and monitored natural attenuation, and describes new approaches with emphasis on bioremediation, like biostimulation, bioaugmentation and phytoremediations applied to sediments.

TL;DR: The results indicate that street dust in Baoji has elevated heavy metal concentrations, especially Hg, Pb, Zn and Cu, which are 16-77, 7-92, 6-26 and 4-12 times the background levels in Shaanxi soil, respectively.

TL;DR: The thermodynamics of Pb(II) adsorption onto the Fe(3)O(4) nanoadsorbents indicated that the adsorbed was spontaneous, endothermic and physical in nature.

TL;DR: GFP has the potential of application as an efficient sorbent for the removal of CV from aqueous solutions for remediation of dye-contaminated wastewaters using a solid waste generated by the citrus fruit juice industry.

TL;DR: In conclusion, antibiotics, particularly macrolides and quinolones, are widespread environmental contaminants, and urban STPs are confirmed a major source of the contamination.

TL;DR: This hydrometallurgical process is found to be simple, environmentally friendly and adequate for the recovery of valuable metals from spent LIBs.

TL;DR: Modified nano-alumina with DNPH is favorable and useful for the removal of these metal ions, and the high adsorption capacity makes it a good promising candidate material for Pb(II),Cr(III) and Cd(II) removal.

TL;DR: The combination of the superior adsorption and the magnetic properties of Fe(3)O(4) nanospheres can be useful as a powerful separation tool to deal with environmental pollution.

TL;DR: The experimental results show that the best Ce-Ti mixed-oxide catalyst yielded 98.6% NO conversion, and 100% N(2) selectivity at typical SCR reaction temperatures (300-400 degrees C) and the high gas hourly space velocity of 50,000 h(-1).

TL;DR: This study demonstrated that bamboo charcoal could be used for the removal of Cd (II) ions in water treatment and fitted Langmuir, Temkin and Freundlich isotherms well, but followed LangmuIR isotherm most precisely.

TL;DR: The results indicate the usefulness of L. luteus inoculated with a bacterial consortium of metal resistant PGPRs as a method for in situ reclamation of metal polluted soils.

TL;DR: Combined adsorption and partition mechanisms well depicted sorption of atrazine and simazine on carbonized and noncarbonized fractions of the biochar in the single-solute and co-Solute systems.

TL;DR: The study examined the effect of operating conditions (zinc oxide concentration, pH and irradiation time) of the UV/ZnO photocatalytic process on degradation of amoxicillin, ampicillin and cloxacillin in aqueous solution.

TL;DR: The data reveals that the soil in the area is significantly contaminated with heavy metals such as chromium, and distribution and correlation of heavy metals in soil along with possible remedial measures are discussed.

TL;DR: High performance liquid chromatography coupled to a diode array detector method was developed to detect disperse dyes in water samples over the range 0.50-35 ng, with detection limits of 0.09 ng, 0.84 ng and 0.08 ng, respectively, with good repeatability and accuracy, that are contributing to the mutagenicity found in the Cristais River, São Paulo, Brazil.
