Activated Alumina For Water Purification

  • Saturday, May 07, 2022

The dihydroxylation process produces activated alumina from aluminum hydroxide to give a porous solid object. These are widely used as desiccants and filters for water purification.

Natural drinking water contains many minerals like fluoride, arsenic, selenium, etc. These minerals are the reasons for considering water as a precious part of our diet and good health. But if any of these minerals exceed the permitted limit, it can lead to severe health issues. Thus, the purification of water is highly recommended. In this article, we will see the role of activated alumina in water treatment

 

 

Water purification by activated alumina

The principle works in removing arsenic content by the activated alumina bed. Known as adsorption. The arsenic content in water may rise beyond the permissible boundaries due to deposits from industries, agricultural processes, or even through natural means. When in huge quantities, this will cause many health issues. 

The water to be treated is allowed to pass through a bed of activated alumina under high pressure. More than one filter bed can be used back to back for improved results. The arsenic content gets adsorbed by activated alumina beds when passed continuously for a pre-determined time, and the processed water is collected for further use. 

The quality of the activated alumina arsenic removal process depends on certain water factors under treatment, such as pH, water quality, presence of other impurities, and compound form of arsenic. Arsenic can be present in two forms, As (V) (arsenate) and As (III) (arsenite). It is recommended to process the water before it is passed through an activated alumina bed and oxidize the As (III) to As (V) because the alumina filter handles As (V) more efficiently. Also, the pH range of water is to be maintained within 5.0 to 6.0 for smooth and maximum adsorption.

 

Benefits of using Activate Alumina

One main benefit of using activated alumina for water treatment is that it is resistant to liquid water. This means it will not shrink, swell or get diluted when immersed in water for a long time. The activated alumina beds can be regenerated and reused. The high surface area and high adsorption capacity place the activated alumina as one of the best methods for water purification.

Air Drying Desiccant to Absorb Moisture Efficiently!

  • Wednesday, Apr 20, 2022

Desiccants are said to those substances which can absorb moisture and odor. Having excellent absorption capacity, it can maintain the product's originality by preventing any microbial activities. Although moisture is present everywhere, its presence is unnecessary places can be quite disastrous. Most of the desiccants are available in granular or powdered form. The reason that these desiccants are in this form is that in this way, it gets more surface area for absorption. This form allows the desiccant to absorb more moisture content from the atmosphere. However, these desiccants cannot be used loosely, so they are used in packets. Now the size of the packets depends on the requirement. You must have seen small packets of desiccants in leather jackets and plastic containers. While at the same time, huge bags of desiccants are also used while transporting that cargo on a ship.

There is various type of air drying desiccants available in the market. The most popular and widely used desiccant is silica gel. It also comes in three variants that are orange, white, and blue. Among the three, orange and blue are the color-changing gel. After absorbing moisture, the granules change their color, indicating that the desiccant granule is contaminated and needs to be replaced. Another reason which makes it more popular is that once it is fully contaminated, it can be reused again by heating it over 300oC. The other type of desiccant is molecular sieves. Its properties are quite similar to that of silica gel. The advantage of using it over other desiccants is that its absorption speed is more, and it has more resistance to contamination.

Apart from this, there are other desiccates like activated carbon and clay. So desiccants can either be used alone or in combination with the other ones. In this way, we can get rid of two factors at a time that is moisture and odor. For example, silica gel and activated carbon can be used where silica gel can absorb moisture, and activated carbon can absorb odor. Clay is said to be a natural desiccant. It is said to be the most efficient and cost-effective desiccant. One drawback of this desiccant is that it needs to be replaced immediately after it is contaminated.

Sorbead India is the manufacturer and supplier of alumina balls desiccant for the industrial air-drying process. Air drying desiccants are used for compressed air drying, heated & heatless air drying, etc.

Activated alumina balls are not only a bad conductor of electricity but have a good capacity to resist heat for a long duration. Its rigidity is that the alumina molecules are very close to each other; thus, its density is quite high. And this is the reason the most common shape given to alumina is in the form of balls. The external surface of the alumina ball is quoted with such a solution so that it can easily reflect sunlight avoiding any reaction. Alumina balls manufacturer designs the surface of the balls smooth, which makes it idle to use in various grinding processes. Apart from this, it is also used for filtration purposes. It is also used to abstract minerals from ores by making them highly porous. These white coloured balls are usually combined with the latest technology to ensure their flawlessness.

Why do compressed air and gas need drying?

  • Friday, Dec 03, 2021

Being the fourth utility of a production facility (the other three being electricity, water and gas) compressed air is a very important resource that should be carefully treated in any manufacturing plant. It should be carefully examined in a periodical manner. The moisture present in the air should be removed and also the contaminants should be eliminated. This will result in the efficient working of the whole system. Improved performance and reduced operational costs are two major perks of having efficient air and gas drying systems. 

Air drying is one of the most significant processes carried out in most large industries. In this technique, the moisture from coatings and surfaces are removed by using hot, dry or forced air. Moisture present in the air can affect colour, coatings etc., and also lead to damage and corrosion. But air-drying is employed to prevent all those problems. 

Significance of compressed air and gas drying

Regular atmospheric air and compressed air all contain some amount of water vapour. This water vapour will cause problems in future because of an increase in water concentration in the system. Therefore, to prevent problems in the future, wet air must be controlled. Drying equipment can be used for the same purpose. 

There is moisture present in the irregular atmospheric air that will have moisture content. When the air or gas crosses the saturation point, this vapour will condense and reach the liquid state. This process happens at a certain temperature and this temperature is known as the dew point. 

  • Moisture leads to damages and problems

When the compressed air employed in the manufacturing plant contains moisture, it will damage various valves, pneumatic air systems, air motors, different passages etc. They will cause damages, wear and tear, impact lubrication, corrosion, causes the valves and passages to be plugged and clogged and also affects the overall functioning of the system. Further, the moisture harms the adherence, colour and finish of paint etc. Hence, they- lead to malfunctioning, false readings in the instruments, faulty operations, and even cause the total system to shut down. 

Compressed air and gas drying becomes necessary to obtain perfectly finished products, for the smooth flow of uninterrupted production, improved performance of the whole system and reduced operating costs.

  • Clean and dry air, as well as gas, is necessary for various applications

Air is required in most manufacturing facilities or plants. Most of these plants need dry and clean compressed air for the smooth flow of their operations. Water molecules, dirt or any other contaminants will be deposited inside the pieces of equipment that can even lead to a drop in the pressure of the system. This drop indicates low efficiency in the overall performance of the system. 

  • Instrument air used in transmitters, converters, gauges etc., need to be dry

In these pieces of equipment, dry and moisture-free air is needed, as even a little amount of moisture or water vapour can produce significant issues. This may plug the air passages and block them. Further, they can lead to instrument damage. Pneumatic thermostats that are used in the air conditioning and heating cycles of buildings is another instrument that needs dry air.

These types of instruments used in sewage treatment units, manufacturing plants, textile manufacturing units, petrochemical plants are all examples of facilities that need dry air for their smooth flow and efficient operation.

  • Valves, as well as cylinders, need moisture free air for their smooth functioning

The slime or sludge that is formed by the dirt and contaminants or oil in the air causes blockages in valves and acts as drags in the cylinders. This causes damages and results in frequent maintenance. There will be a lag in operations, this slowdown of operations will gradually lead to the shutting down of the system. The efficiency will be very low and there will be an increase in costs too.

These are the main reasons why compressed air and gas need drying. Air-gas drying can be achieved through various techniques. Use of air dryers is one popular technique used nowadays and among them, use of desiccant air dryers is the one with most demand as it employs a heatless method. 

The regenerative desiccant air dryers use a desiccant. Activated alumina balls are used mainly in these systems nowadays. These desiccants absorb all moisture content from the air. They have the maximum water adsorption capacity than other adsorbents including silica gel and molecular sieves. Activated alumina balls are exceptional adsorbents of water vapour and moisture. They are highly porous non-toxic substances with high surface area. Sorbead India is one of the most reliable suppliers of high-quality activated alumina balls in India. They provide activated alumina balls of different sizes and types for different types of air dryers.
