Pollution prevention protects the environment by conserving and protecting
natural resources while strengthening economic growth through more efficient
production in industry and less need for households, businesses and
communities to handle waste.
Pollution leads to loss of biodiversity, global warming, reduction in the number of
plant and animal species, etc. Human health is largely impacted by degradation of
the environment. Reduction in quality of air, water and other resources poses a
threat to human life. Hence, pollution control is extremely important.
Why is industrial pollution important?
Industrial pollution is considered an important factor to contaminate the
environment. It results in environmental degradation and imposes heavy costs on
society as well as on human health and safety. Textile, cement, glass, plastic, sugar,
tanning, petroleum are major polluting industries.
Why industrial pollution is a problem?
There are a number of forms of industrial pollution. Industrial pollution
impact air quality and it can enter the soil, causing widespread environmental
problems. Industrial activities are a major source of air, water and land pollution,
leading to illness and loss of life all over the world.
What are the main industrial pollution?
The major industrial pollutants affecting air quality are sulphur dioxide, volatile
organic solvents, and particulate materials, such as metal dust. Burning waste,
particularly plastics, can also produce dioxins and other hazardous chlorinated
compounds.
What is Dust?
Dust is made of fine particles of solid matter. On Earth, it generally consists of particles in the atmosphere that come from various sources such as soil lifted by wind, volcanic eruptions, and pollution. Dust in homes is composed of about 20–50% dead skin cells. Industrial dust, also known as process dust, is generated during the manufacturing or production process. For example, cutting, drilling, grinding, or sawing generates dust. It can also break out from materials, chemicals, or ingredients used in the production process, such as flour, sugar, and pharmaceutical products. Misting is the most effective way to stop dust in the air in terms of cost and efficiency. Using the optimum amount of water makes misting systems the ideal way to control airborne dust. Dust control solutions, like Dust Boss cannons, use atomized mist to create fine water droplets in the 50 – 200 micron range.
The prolonged exposure of industrial dust can lead even to lung cancer. Some dust particles are so small that they directly absorb themselves in the bloodstream eliminating some of the common symptoms and instead lead to nausea, loss of balance and other symptoms, usually typical for poisoning. Without proper dust extraction and dust control, you are exposing yourself to harmful dust, particulates, and contaminants in the air. These airborne particles can significantly affect your health and well-being
Types of Dust :
Metal Dust:
Metal dust usually forms by grinding metal during any metal manufacturing process. Workers subjected to metal dust can suffer from lung and throat irritation. Other sorts of metal dust are often highly poisonous, particularly if the metal consists of heavy metals such as cobalt, lead, or nickel. If dealing with the metal it is necessary to wear any form of a respirator to avoid injury to the lungs.
Plastic / Fiberglass Dust:
Fiberglass, or glass wool, consists of glass filaments combined with yarn and woven into a cloth. Although there is inadequate data, many suspect that fiberglass can cause respiratory diseases when worn down and turned into an airborne material. Wearing a mask when working with fiberglass or other manufactured plastics is strongly suggested as a precautionary measure.
Wood Dust:
Wood dust is additionally referred to as sawdust, as a result of wood manipulation. Whether it’s by sanding, scraping, digging, or shaving, small wood particles are emitted into the soil, creating a coating of dust until deposited. Wood dust are often hazardous when inhaled. It may cause allergic reactions, problems with the oral mucous membrane, or cancer, although the extent of these risks has not been fully identified.
Concrete Dust:
The silica dust is airborne while dealing with concrete and might be harmful. Exposure to silica dust may result in a disease caused by inhaling an excessive amount of the silica found in dust. Such small particles may cause the lungs to thicken or scarring of lungs, and eventually trigger lung cancer.
Chemical / Pharmaceutical Dusts:
This kind of dust is generated while conveying pharmaceutical/chemical powders from one place to another for their processing in plants. This will be very harmful as sometimes these powders are hazardous if inhaled. Even the utilization of masks might not be sufficient to arrest them. So dust collectors are necessary for such applications. These dust collectors in first place refrain from releasing such particles within the atmosphere by arresting them in the process itself.
What are the three categories of dust?
Different types of dust also carry different risks to human health and can be classified into three types: L Class (Low Risk), M Class (Medium Risk) and H Class (High Risk). Each class has a maximum allowable concentration, which is essential for employers to understand
Examples of the types of dust found in the work environment include:
- mineral dusts, such as those containing free crystalline silica (e.g., as quartz), coal and cement dusts;
- metallic dusts, such as lead, cadmium, nickel, and beryllium dusts;
- other chemical dusts, e.g., many bulk chemicals and pesticides
Industrial Air Pollution Control Equipment: Introduction, Types and Uses
Air Pollution control Equipment is a vital component of industrial processes that cannot be neglected. Name any industry, and you will realize the extent of harmful stuff it sends into the environment through its processes. Petroleum, energy production, coal and metal mining, chemical, and waste management industries are a few of the many players that have played a considerable role in polluting the environment. Every industrial procedure – including sourcing of raw materials, manufacturing of the final product, maintenance of the site and machinery, and transporting of the product to different locations – results in some kind of pollution. The burning of fossil fuel releases volatile hydrocarbons, burning wood and coal as fuel produces carbon dioxide and sulphur dioxide, and automobiles are also a key source of harmful carbon. Each industrial activity generates emissions that directly pollute the air, soil, or water.
The goals of industrial air pollution control equipment are to:
- Decrease the release of harmful gases and control the spread of air pollution.
- Conserve whatsoever natural resources are available for our future generations.
- Decrease health threats posed by breathed in and otherwise consumed pollution.
Air pollution is a threat to nature and due to rapid industrialization, it has become a need of the minute to control it. https://envirocondeep.com is a manufacturer and provider of air quality control equipment. We recognize that the growth of the country is directly related to the production in factories, but also there is a need to monitor airborne contaminants. Let’s see some of the pollution management equipment and there uses.
1. Bag filters:
The bag Filter is separated into many sections and every component includes a filter bag that removes the particles throughout the process. The collected particles and dust are spread over the fabric and, as the coating thickens, it can be extracted for washing or be dry cleaned so that it may function more effectively. Such elements can be made of nylon, polypropylene, polyester or porous PTFE.
2. Pleated Bag Filters:
A Pleated Bag Filter is an analogous equipment to bag filters, where, instead of using a simple element made of fabric, the element consists of pleats which in turn increase the surface area for filtration per element. This effectively reduces the total space required for such a unit. Depending on the selection of media as per the application, such filters can be either used for surface filtration or depth filtration. Pleated Bag Filters can also remove submicron particulates.
Benefits of Pleated Bags
- Polyester media and PU end caps in the bottom prevent abrasion/leaks Can be retrofitted into existing bag filter dust collectors using existing tube sheet holes (adaptor rings enable easy installation in tube sheets.
- Short pleated bag filters can optimize the capacity of existing collectors – hence prevent the need to invest in larger baghouses. Also, they require less air for efficient pulse cleaning.
Benefits Of Surface Filtration:
- Less accumulation of dust
- Less pressure drop
- Longer filter life cycle
3. Cyclone:
The function of a cyclone dust Collector is extremely simple. It works on the principle of centralizing the mixture of air, forming a vortex, and entering the device. It uses a cyclonic separation process to isolate particles without the utilization of filters. The only downside is that it is limited to be used with coarser materials and cannot be used with fine powders.
Uses: They are widely used in industries like power plants and several industries like polyolefin, pulp, and paper plants, cement plants, petroleum and coke industry, metallurgical plant, sawmills, and other units.
