This document summarizes a study on using granular activated carbon to adsorb synthetic batik dye from wastewater in a continuous system. The study examined the adsorption of methylene blue dye onto activated carbon in fixed bed columns. Key findings include: (1) Activated carbon showed good potential for removing methylene blue from aqueous solutions, with up to 87.7% removal achieved; (2) Higher initial dye concentrations led to higher adsorption capacity; (3) Adsorption reached completion within 3 hours of contact time. The continuous adsorption process using activated carbon is presented as a potential wastewater treatment method.
Equilibrium and kinetic studies on the adsorption of methylene blue from aque...suresh899
In the present study, activated carbon is prepared from Murraya koenigii Stems (MKST) and used for the adsorption of methylene blue
from aqueous solution. The nitrogen adsorption isotherms were used to characterize the pore properties of the activated carbon including
the BET surface area, pore volume and pore diameter. The specific surface area of the prepared carbon is 508 m2/g. Batch mode experiments
were conducted to study the effect of adsorbent dosage on the adsorption of methylene blue. The equilibrium data fits well with Langmuir
model with monolayer adsorption capacity of 123.46 mg/g. The adsorption kinetics was studied using pseudo-first order and pseudosecond
order models. The rate of adsorption was found to conform to pseudo-second order kinetics with a good correlation. The results
show that methylene blue interacts strongly with the prepared activated carbon and hence the adsorbent is good for the removal of
methylene blue from aqueous solution.

The adsorption of mixture of two basic dyes methylene blue and malachite green in aqueous solution onto jack fruit leaf ash in a batch system with respect to initial dye concentrations, pH, contact time, shaker speed and adsorbent doses was investigated.. The pseudo-first-order and pseudo-second- order kinetics model were used to describe the kinetic data. The rate constants at different pH values (3-9.1) were evaluated. The experimental data fitted well with the pseudo-second-order kinetic model. Equilibrium isotherms were analyzed by Langmuir, Freundlich and Temkin isotherm models. Maximum adsorption capacity was 20.41mg/g was achieved by Langmuir isotherm model. Error analysis was done to find the best model that described the experimental data well and it was the Langmuir model. The result indicated that jack fruit leaf ash could be fruitfully employed as low cost adsorbent for the removal of mixture of two basic dyes MB and MG from the wastewater.

Abstract Ultrasonicated Membrane Anaerobic System UMAS was successfully used for sewage sludge treatment and biogas production. Central Composite Design and Response Surface Methodology were used to determine the optimum conditions in which UMAS produce a maximum content of methane in the biogas produced. The effects of three variables namely pH, chemical oxygen demand (COD) and organic loading rate (OLR) on methane content were evaluated individually and interactively. The optimum conditions obtained were pH 7.74, COD 1061.06 Mg/l and OLR 0.90 kg/m3d. The predicted maximum percentage of methane was 89.72 % and confirmed close to RSM result.

A New Low Cost Biosorbent for a Cationic Dye TreatmentIJEAB
The aim of our study consists to investigate the adsorption of Methylene Blue from aqueous solution by a new biosorbent prepared from Papaya seed. Adsorption behavior of the cationic dye was analyzed by variation of solution pH, contact time, adsorbent dose, and temperature. Adsorption isotherms were studied according to the Langmuir and Freundlich Model, and adsorption kinetics according to pseudo first and second order. Results show that the maximum adsorption is obtained at ambient temperature with the yield of 98.82% and was reached in first 20min (pH = 10, adsorbent dose of 100 mg in 50 mL). The Langmuir isotherm shows a correlation coefficient of 99.4% higher than 95.4%obtained for Freundlich model and the adsorption kinetic model follow a pseudo-second order with a maximum adsorption capacity of 52.28 mg/g.

Enhancing the adsorption of disinfection by products onto activated carbon us...Ahmed Hasham
The removal of contaminants from consumable waters by the traditional water treatment techniques is highly difficult. Disinfection of water alludes to the inactivation or pulverization of unsafe living pathogenic beings, which living in the water. Occurrence of disinfection by products (DBPs) during disinfection normally demonstrates lethal impacts on human health. Granular activated carbon (GAC) has the oldest history of decreasing of organic matters, but its role is reducing by time. TiO2 is used to accelerate the removal of the DBPs. TiO2 nanoparticles have good adsorption phenomena on the removal of those organic compounds at various pHs and temperatures and give good results. This study proved that TiO2 nanoparticles enhanced the efficiency of GAC to remove DBPs from water. While the elimination of trihalomethanes (THMs), dichloroacetic acid (DCAA) and trichloroacetic acid (TCAA) using 0.5 g of GAC was determined as 61.7, 69.8 and 83.2% respectively, the elimination of them by 0.1 g of TiO2 nanoparticles :GAC (1:1) was estimated as 100, 96 and 100%, respectively.

Abstract
Wastewater pollution is always consider as dangerous because it has been affected by the hazardous or
dangerous chemicals and release to the water source such as rivers, lakes and oceans. There are several ways to
treat the waste water. It consists of physical, chemical and biological method. The continuous adsorption in fixed-
bed column is often desired from industrial point of view. It is simple to operate and can be scaled-up from
