The use of step and pulse tests to design activated carbon adsorption columns for recovery of copper ions from aqueous industrial effluents
Dynamic experiments were carried out on the adsorption of copper ions in a laboratory packed bed of activated carbon. Both pulse and step change inputs were used. Measurements were reproducible and replicate measurements furnished nearly identical parameters for a conventional heterogeneous model of the activated carbon bed, assuming a Langmuir adsorption isotherm. Bed depth had little effect on ...

Integrated maximum efficiency air pollution control system
A major uranium refiner required an air pollution control system to control emissions from their hazardous incinerator. The presence of radioactive material demanded that outlet emissions approach non-detectable levels. Macrotek was contracted to design and supply the system. Advanced, cutting edge technology was used to design a system with the lowest possible emissions, which has been ...

Separation of hydrophobic organic compound from surfactant solutions with activated carbon in a fixed bed
The adsorption behavior of phenanthrene (PHE) in Triton X-100 (TX100) solutions with fixed activated carbon (AC) bed was studied to recover the surfactant. The effect of various parameters like bed depths, flow rates, influent TX100 concentration, and influent PHE concentration were investigated. The breakthrough time of both TX100 and PHE increased with the increase of bed height and decrease ...

Assessment of Activated Carbon Stability toward Adsorbed Organics
Activated carbon technology is widely employed in solvent recovery and air pollution abatement systems. Activated carbon beds containing organic molecules sometimes come into contact with air or oxygen, in some cases, as a consequence of their normal operations. A number of investigators (Miller et al., 1987; Chapman and Field, 1979) have reported exothermic runaway reactions under these ...

Flow-through electrosorption process for removal of 2,4-D pesticide from aqueous solutions onto activated carbon cloth fixed-bed electrodes
Wastewater treatment systems have great importance in dealing with increasing environmental pollution. In this study, a specially designed and constructed flow-through electrochemical cell was used to enhance the electrosorptive removal capacity of 2,4-Dichlorofenoxyacetic acid (2,4-D) pesticide from aqueous solutions onto high area activated carbon cloth (ACC) fixed-bed electrodes. The ...

UV Technologies for Chlorine Removal from Water
Chlorine is widely used in water treatment as a disinfection and oxidizing agent. However, the reaction of free chlorine in water leads to the generation of undesirable by-products and have harmful effects on industrial processes. In high purity water systems, the presence of free chlorine in water may result in the deterioration of treatment units such as ion exchange beds and RO membranes. ...

Modeling of heavy metals removal from aqueous solution using activated carbon produced from cotton stalk
Activated carbon produced from cotton stalks was examined for the removal of heavy metal contaminants. Adsorption studies in completely mixed batch reactors were used to generate equilibrium pH adsorption edges. Continuous flow experiments using the activated carbon in fixed beds were conducted to determine heavy metal breakthrough versus bed volumes treated. At given pH value in the range ...

Monitoring fuels in Stormwater - Case study
The Situation A major pipeline company has large storage tank farms throughout the Western States. The pipeline company transports, stores, blends additives, and distributes gasoline, diesel, and jet fuel to retail service stations and airports. Due to the quantity and movement of fuel at these facilities, there is always the potential for fuel spills. These facilities prevent out of compliance ...

Wet dust collection for Dry ingredients - Case study
Wax products producer achieves 99% efficiency using Tri-Mer Dust Collection Equipment. The company’s first priority was a system that would collect fugitive particulate with consistently high efficiency. Low utility cost and minimal maintenance were also important. Wet particulate collection was specified at the outset because the vapor carried with the airstream would quickly blind ...

What is the Chemical Structure of Activated Carbon?
Known since antiquity as a powerful purification agent, activated carbon is used today in a vast array of applications at the home, municipal, and industrial levels. Activated carbon can be made from any organic material with a high natural concentration of carbon, so the specific chemical structure and properties will vary according to which raw material is selected. Here is what you should ...

Air Pollution Control in the Printing and Web Coating Industries
For many U.S. companies in the printing and web coating business, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new. In these industries, depending upon their location, companies have been installing APCS since the early 1970's. However, for some companies the clock is still ticking regarding their compliance with local, state and federal clean air ...

gaiasafe filter products for drinking water purification - Case Study
Problem In some water works chlorination of drinking water is used to eliminate mikrobes. Chlorinated water may have disagreable taste and smell. Some water works use aluminium salts to clean the water. This leads to low concentrations of aluminium in drinking water. Today it is known that aluminium may be toxic to men. Old piping installations inside or outside private homes often where made of ...

Biofilters vs Asdorption
In the last three decades biological technologies have emerged as a sustainable and economically-viable alternative compared to traditional techniques like adsorption/absorption for purifying gases. They were well-received initially in the industry and interesting products with good results were carried out for several years. However, owing to a series of reasons that will be detailed in this ...

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 ...

Gravity driven membrane filtration system to improve the water quality in rainwater tanks
The characterisation of rainwater in metropolitan Sydney and in rural New South Wales was undertaken. The results showed that factors such as the lack of vehicular traffic, air pollution and urban contamination meant that rural rainwater water quality was better. The rain water collected in both metropolitan and rural areas generally complied with the 2004 Australian Drinking Water Guidelines ...
