OPTIMUM BACKWASHING PROCESS FOR ACTIVATED CARBON FILTRATION

Hydrodynamics and mass transfer inthree-phase airlift reactors for activated Carbon and sludge filtration

A bioreactor refers to any manufactured or engineered device that supports a biologically active environment. These kinds of reactors are designed to treat wastewater treatment. Volumetric mass transfer coefficient and the effect of superficial gas velocity, as the most important operational factor on hydrodynamics, in three-phase airlift reactors are investigated in this study. The experiments...

Organic Micropollutant Removal by Biological Activated Carbon Filtration: A Review

Performance Evaluation of Combined Process of Powdered Activated Carbon-Activated Sludge (PACT) in Textile Dye Removal

Introduction: The Powdered Activated Carbon Treatment (PACT) has been proposed as an alternative in wastewater treatment and wastewater biomass protection against toxic substances. This study aims to evaluate PACT performance in treating dyes, acid orange, and remazol brilliant reactive blue. Materials and Methods: This empirical- applied research was carried out in pilot scale in which differ...

Effects of coconut granular activated carbon pretreatment on membrane filtration in a gravitational driven process to improve drinking water quality.

This study evaluates the performance of a polymeric microfiltration membrane, as well as its combination with a coconut granular activated carbon (GAC) pretreatment, in a gravitational filtration module, to improve the quality of water destined to human consumption. The proposed membrane and adsorbent were thoroughly characterized using instrumental techniques, such as contact angle, Brunauer-E...

Removal of Coliform, Suspended Solids, UV254 and Colour Using Zeolite and Activated Carbon in Riverbank Filtration System

River bank filtratio filtration (RBF) is one of the novel water abstraction alternatives to tackle poor water quality problem in Malaysia. This study was conducted to investigate the potential use of zeolite and activated carbon as filter media in the laboratory RBF system. Characteristics of the materials were first determined using the surface analyzer and X-ray fluorescence method. Filter co...
