Adsorption of Zn2+ and Ni2+ in a binary aqueous solution by biosorbents derived from sawdust and water hyacinth (
Eichhornia crassipes )The Zn2+ and Ni2+ adsorption capacities of six biosorbents derived from water hyacinth (Eichhornia crassipes) (WH) and sawdust (SD) were investigated, with activated carbon as the control. The biosorbents were raw biomass (WH, SD), charred WH (BWH) and SD and sulphonated bio-chars of WH and SD. The effect of the initial solution pH and Zn2+ and Ni2+ concentrations on ...

Fundamentals of Catalytic Activated Carbons
Untitled Document Summary: Catalysts in water treatment speed chemical reactions so equipment can be scaled down or contact times shortened. Because the speed of a reaction can affect equipment price or useful life, it could mean the difference between a sale and a "no, thanks." Thus, recently developed catalytic activated carbons may enable water treatment ...

What is Activated Carbon?
Adsorption with activated carbon can apply. The more awareness people have of the Earth, the more applications activated carbons will have. is thus a commonly seen process in applications such as gas masks, space capsules, nuclear plants and so forth, in which the removal of gases is highly needed. Why is it known as the universal adsorbent? Activated carbon can apply. The more awareness people ...

Characterisation of activated carbon prepared from tamarind wood for wastewater treatment
In this paper, an attempt has been made to produce activated carbon from tamarind wood, which is a forest waste, rich in lignocellulosic material. The characterisation of the activated carbon is done based on carbonisation time, temperature, pore volume and Brunauer, Emmett and Teller (BET) surface area under various operating conditions. The Scanning Electron Microscopy (SEM) analysis is also ...

Abatement of Cr(VI) rich wastewater in a novel multistage External Loop Airlift Reactor using acidified activated carbon
In the present investigation, a multistage External Loop Airlift Reactor (ELALR) has been used for the treatment of Cr(VI) rich wastewater using acidified activated carbon as the adsorbent. The multistaging has been achieved by hydrodynamically induced continuous bubble generation, break-up and regeneration. The continuous rupture and bursting of bubbles creates localised turbulence and ...

Physico-chemical treatment of anaerobic landfill leachate using activated carbon and zeolite: batch and column studies
Leachate generated from one of the old landfills in Malaysia contains high concentrations of colour, COD, iron and ammoniacal. The ability of activated carbon-zeolite mixtures as an adsorbent was investigated in this research. Results of the batch experiments indicated that more than 522.2 mg/g of colour, 52.63 mg/g of iron, 232.6 mg/g of COD and 21.01 mg/g of ammoniacal nitrogen were removed by ...

The Many Uses of Activated Carbon
Activated carbon is processed to have small, low-volume pores that increase the surface area available for adsorption. It has applications in the medical, environmental and energy realms, among others. Since 1962, ASTM Committee D28 on Activated Carbon has developed standards that play a pre-eminent role in how activated carbon is used. A D28 subcommittee, D28.02 on Liquid Phase Evaluation, is ...

Removal of bromate and natural organic matter by using biologically activated carbon
The removal of bromate and Natural Organic Matter (NOM) during the transition from fresh GAC to BAC was investigated by using two GAC filters with different type of GAC. The removal of bromate, nitrate, NOM in GAC filter apparently decreased during the transition. Although high level of anions and NOM, and high pH value may greatly affect bromate reduction in GAC filter, in initial period one GAC ...

A comparative study on removal of basic violet 10 by adsorption and photocatalytic degradation using low cost activated carbon
This study compare the adsorption and photodegradation methods for the removal of basic violet 10 (BV) dye. Adsorption studies were carried out using activated carbon prepared from rice husk (RC). The photocatalytic degradation reactions using RC + TiO2 mixture were carried out under UV irradiation. The influence of operating parameters governing dye removal such as contact time, pH and effect of ...

What is Activated Carbon Filtration?
The process may have ancient roots, but still plays a role in modern water treatment Activated carbon filtration is one of many processes commonly used in water treatment to remove contaminants such as organic materials, and since it also can remove odor-causing contaminants, it’s often used to make drinking water more palatable. The first known carbon filtration devices date back to ...

Adsorption of heavy metal ions by natural and synthesised zeolites for wastewater treatment
The removal of heavy metal ions, Pb(II) and Cu(II), by adsorption using natural zeolite (NZ), synthesised zeolite (MCM-22) (SZ), and powdered activated carbon (PAC), were examined and compared. The influences of contact time, solution pH and adsorbate concentration have been tested in kinetic runs. The equilibrium sorption capacities of copper and lead ions on NZ, SZ and PAC were found to be ...

Primary treatment of anaerobic landfill leachate using activated carbon and limestone: batch and column studies
Leachate generated from an old landfill in Taiping, Perak, Malaysia contains high colour, COD, iron and ammoniacal nitrogen. Activated carbon?limestone mixture was used as a primary treatment process. More than 86% of colour and COD, 95% of iron, and 48% of ammoniacal nitrogen were removed by a mixture of activated carbon and limestone (15:25 by volume) in the batch study compared with 70, 80 and ...

Activated carbon for the removal of pharmaceutical residues from treated wastewater
Pharmaceutical residues, which pass naturally through the human body into sewage, are in many cases virtually unaffected by conventional wastewater treatment. Accumulated in the environment, however, they can significantly impact aquatic life. The present study indicates that many pharmaceutical residues found in wastewater can be removed with activated carbon in a cost-efficient system that ...

Activated Carbons from lignocellulosic waste materials for water treatment: a review
Activated Carbon (AC) adsorbents are commonly used to remove pollutants from water because of their excellent sorption ability. However, commercially available ACs are expensive. In developing countries where economy plays a very big role, it is better to find low-cost locally available precursors, which are renewable resources for the preparation of ACs. This review focuses on ACs prepared from ...
