In Part 1 of this series, we talked about the need to protect the factory interiors from air pollution. Some of these plants recycle our waste, but they deeply damage their own health in the process. Today we’ll take a broader look at the problem. Regarding air pollution and its relation to filtration, multiple sectors are involved. They include power generation (both fossil fuels and renewable energy), manufacturing, healthcare, metals, and more. The type of air filter used in a firm depends on the type of in-house waste it generates. Air pollution can be in the form of mists, powders, or dust. Filter types include:
1. Dust collectors
2. Mist absorbers
3. Cartridge filters
4. Hepa filters (High-efficiency particulate air)
5. Baghouse filters
For decades now, we’ve been worried about pollution greenhouse gases, and global warming, so why the sudden interest in indoor air pollution, especially on commercial premises? Well, we’re generally more aware of our impact on the environment and its long-term effects. The world is industrialising at a rapid pace, which means we’re putting more strain on our natural surroundings. Moreover, as we seek energy sources that are high on efficiency and low on emissions, we release by-products into our manufacturing plants that we hadn’t factored in.
Benefits of air filtration
The air filtration industry is therefore essential. It helps us increase production capacities, lower overheads and manufacturing costs, make industrial activities more efficient, and save energy. And yet the industry is slowing because of the global recession, low air filtration sales, and lack of incentives to make this sector attractive. The need is there, but economic priorities are reducing interest levels.
Fortunately, government regulation is nudging air filtration back on track. As anti-pollution laws become tougher, businesses are forced to apply those measures, which results in sales for air filtration experts. In the field of electronics and electricals, as well as certain industrials sites, air filtration focuses on dust collection. This is crucial because the smallest spec could damage both the manufacturing equipment and the end-product.
Air pollution vs water pollution
At the moment, there’s a higher demand for liquid filtration than there is for air filtration, even though low-quality industrial air has a more visible immediate effect on the health of workers. Liquid waste is expensive though, which explains the emphasis. Also, in some manufacturing plants, production stalls if liquids aren’t recycled. Consider coolants, cutting fluids, groundwater deposits, and wash water from food products or mechanical parts. These all have to be treated before moving to the stage of the next production.
Also, because air is mostly invisible and liquid occupies a lot of storage space, liquid filtration takes priority, if only to create room and restart the production line. However, our collective knowledge base is expanding, and the result is more stringent environmental policies, both at the creation and implementation levels. Eventually, we will match intent with action. We already know how badly we need clean air inside our factories. It’s just a matter of time before our actions follow suit and the right air filtration equipment is universally installed.
