“…Phosphorus is considered a fundamental nutrient for industrial and agricultural production, whereas high concentration of phosphorus in wastewater discharge could destroy the ecological balance and bring serious environmental problems . It is well‐recognized that a phosphorus concentration above 0.02 mg L −1 in receiving water could cause eutrophication . In order to protect the ecological environment, most countries have determined stringent regulations of effluent discharging standard and adopted various strategies to reduce the phosphorus concentration in effluents .Conventional methods, such as chemical precipitation , biological treatment , ion exchange , membrane filtration , and adsorption have been proposed and applied to remove excess phosphorus from wastewater.…”

The aim of this study was to evaluate the potential use of the Hangjin clay ceramic adsorbent for phosphorus removal from aqueous solution and municipal sewage in column systems. The effect of several factors, including bed depth, initial phosphorus concentration, and flow rate was investigated at room temperature. As a result, the breakthrough time increased with increasing in the bed depth, whereas inverse relationship was observed with the initial phosphorus concentration and flow rate. Moreover, municipal sewage treatment results proved the effectiveness of the adsorbent in practical application and further demonstrated some co-existing ions in sewage had little effect on the continuous adsorption process. Adsorption models, which are the basis for the process design at a real scale, were used to estimate the characteristic parameters of columns. The dynamic adsorption kinetic data well agreed with the Adams-Bohart and Clark models. The Yoon-Nelson and BDST models could be successfully used to predict the breakthrough time. The observed maximum dynamic adsorption capacity of the ceramic adsorbent for phosphorus removal was 19.28 mg g 21 . The Hangjin clay granular ceramic could be used as a high-efficiency phosphorus adsorbent in the aspect of the municipal sewage treatment.

“…Soils with higher humate content have higher retention capacity for water and nutrients, improved pH and redox buffering, or higher organic content, which all lead to improved soil fertility [ 14 ]. Both organic pollutants and heavy metals are well sorbed on humic substances [ 10 , 14 , 15 ]. From the bioremediation point of view this usually leads to immobilization and consequent decrease in pollutant toxicity [ 11 , 12 ].…”

Possible enhancement of biodegradation of petroleum hydrocarbons in agricultural soil after tank truck accident (~5000 mg/kg dry soil initial concentration) by bioaugmentation of diesel degrading Pseudomonas fluorescens strain and addition of abiotic additives (humates, zeolite) was studied in a 9-month pot experiment. The biodegradation process was followed by means of analytical parameters (hydrocarbon index expressed as content of C10–C40 aliphatic hydrocarbons, ratio pristane/C17, and total organic carbon content) and characterization of soil microbial community (content of phospholipid fatty acids (PLFA) as an indicator of living microbial biomass, respiration, and dehydrogenase activity). The concentration of petroleum hydrocarbons (C10–C40) was successfully reduced by ~60% in all 15 experiment variants. The bioaugmentation resulted in faster hydrocarbon elimination. On the contrary, the addition of humates and zeolite caused only a negligible increase in the degradation rate. These factors, however, affected significantly the amount of PLFA. The humates caused significantly faster increase of the total PLFA suggesting improvement of the soil microenvironment. Zeolite caused significantly slower increase of the total PLFA; nevertheless it aided in homogenization of the soil. Comparison of microbial activities and total PLFA revealed that only a small fraction of autochthonous microbes took part in the biodegradation which confirms that bioaugmentation was the most important treatment.

“…On the basis of the isotherm data and Langmuir model fitting, a Langmuir capacity of 401 mg g À1 was obtained at pH 6.6-6.9 ( Figure 24). The phosphate adsorption capacity for Fe-Mn nanoparticles is orders of magnitude higher compared with other sorbents such as magnetite, lanthanum-doped vesuvianite (1.32 mg g À1 ) (Li et al, 2009), iron humate (10 mg g À1 ) (Janos et al, 2011), and chemically modified sugarcane bagasse fibers (152 mg g À1 ); (Carvalho et al, 2011). Blaney et al (2007) prepared a new sorbent material, referred as hybrid anion exchanger (HAIX), by immobilizing HFO nanoparticles on an SBA exchange resin of quaternary ammonium function groups.…”
