Geostability of Dewatered Sludge as Landfill Cover Material

by

Mochamad Arief Budihardjo et al. View all

Solid Waste Management

Dewatered sludge is the main by-product from wastewater treatment and it contains various types of hazardous substances which can cause environmental pollution. The alternative utilization of sludge waste is for covering the landfill or as liner for the landfill. Landfill cover is a critical...

Investigation of Copper Ion adsorption using Activated Sawdust Powder: Isotherm, Kinetic and Thermodynamic studies

by

Gokulan R et al. View all

Water and Wastewater Treatment

The batch adsorption technique investigated the efficiency of sawdust adsorbent for removing copper ions from synthetic solutions. A chemical synthesis process prepared the activated sawdust powder, and its surface area and pore volume were obtained by BET isotherm analysis. The ability of copper...

Batch and Packed Bed Column Studies of Azo Dyes Adsorption from the Aqueous Solutions Using Activated Sugarcane Bagasse Charcoal Adsorbent: Isotherm and Kinetic Studies

by

D. Zunaithur Rahman et al. View all

Water and Wastewater Treatment

Biosorption of azo dyes (RO-16, RB-120 & RB-19) from the aqueous solutions was investigated using the activated sugarcane bagasse charcoal adsorbent. The characteristics of the prepared adsorbent were analyzed by SEM, EDX, FTIR, XRD, TG & DT analysis, and the BET surface area of the sugarcane...

Studies on Influence of Process Parameters in Upgradation of Bio-oil Derived from HTL of Domestic household waste: Application of Response Surface Methodology

by

R Gokulan et al. View all

Biowaste

This research focuses on hydrothermal gasification (HTG) and hydrothermal liquefaction (HTL) studies to produce bio-hydrogen from domestic mixed waste. HTG and HTL studies were studied at temperatures of 300–450°C and 300–400°C, correspondingly, with a catalyst level of 6 wt %. The sol-gel technique...

Influence of the addition of M2+ (M: Co, Cu, Zn) on the properties and activity of Mo-TiO2 photocatalysts for water remediation

by

Vakros John et al. View all

Advanced Oxidation Processes for Wastewater treatment

TiO2 is the most effective photocatalyst but it has low adsorption in the visible region. Many efforts have been done to improve its photocatalytic activity in the solar region. In this study we use Mo-oxy species supported on titania surface since it is well known that titania surface can dispersed...

Magnetic CoFe2O4@carbon yolk-shell nanoparticles as catalysts for the catalytic wet peroxide oxidation of paracetamol: kinetic insights

by

Gomes H.T. et al. View all

Advanced Oxidation Processes for Wastewater treatment

This work focuses on the use of carbon-coated magnetic cobalt ferrite nanoparticles as catalysts for catalytic wet peroxide oxidation (CWPO) of the emerging concern pollutant paracetamol (PCM). The magnetic core of the catalyst is composed of CoFe2O4 developed by a sol-gel method. The core is...

Photocatalytic Degradation of reactive violet 1 by Polyorthotoluidine/Titanium dioxide nanocomposite

by

Muhammad Naveed Anjum et al. View all

Advanced Oxidation Processes

Conducting poly(o-toluidine) (POT)/titanium dioxide (TiO2) nanocomposite have been synthesized by in situ chemical oxidation polymerization of o-toluidine in the presence of TiO2 nanoparticles. The various composites were synthesized by changing the percentage load of titanium dioxide nanoparticles...

An innovative solution for the treatment of poultry industry wastewater with advanced hybrid technology sono-photocatalysis

by

Assist Prof Dr Gamze Dogdu et al. View all

Advanced Oxidation Processes for Wastewater treatment

Poultry slaughterhouse wastewater (PSWW) is a crucial concern fundamentally due to extensive generation and related substantial amounts of recalcitrant organic content due to high COD and oil and grease (O&G) levels. Hybrid advanced oxidation processes are promising, green, and innovative options to...

Pillared clay-based catalysts for treatment of 4-nitrophenol solutions by catalytic wet peroxide oxidation

by

Kalmakhanova M.S. et al. View all

Advanced Oxidation Processes for Wastewater treatment

The constant development of technological processes aggravates the problem of pollution, due to a significant change in the composition of effluents, which makes necessary new (and/or improved) treatment methods and catalytic materials. In this sense, the use of natural clays in the synthesis of low...
