We cannot ignore is the consumption and waste of clean water as well as the pollution of the earth’s There is a lot to think about when being environmentally conscious these days. One environmental issue that water ways. The earth is comprised of 70% water yet only 2.5% of that water is fresh water. The need to be conscious of how we use and monitor our use of water is of the utmost importance. Water is used in a variety of different industrial applications while processing many different types of substances and materials. Processes vary from mixing water with mash ingredients in the food and beverage industry, to mixing it with bitumen and additives in numerous applications in the oil and gas and mining industries as well as using it for waste treatment in cities and municipalities. Here is a snippet from an article from encyclopedia.com talking about the scale of consumption of water in industrial processes:
According to the United Nations World Water Development Report, industry accounts for 22% of all global water withdrawals. This varies from 59% in high-income countries, to 8% in low-income countries. Industry tends to use mainly freshwater, as saltwater is unsuitable for most applications because it corrodes the metal parts used in machinery. By 2025, industry will probably account for 24% of global freshwater withdrawals. Although much industrial water is available for reuse, it is usually degraded by the processes it has been involved in, and this type of wastewater will require treatment before its return to the water supply.
The electric power production industry, comprising hydroelectric, nuclear, and coal and oil-fired power stations, account for 50% to 70% of industrial water use. Paper and pulp production, chemicals, mining and metal processing, and petroleum refining all use substantial amounts of water in their operations. The amount of water used in producing various goods and services is called water intensity. Manufacture of a pound of paper takes about 3,000 gallons (11,400 liters) of water, while producing one car takes, on average, about 65,000 gallons (246,000 liters). A pound of aluminum takes about 200,000 gallons (757,000 liters) of water to produce and a hamburger around 1,300 gallons (4,999 liters).
There are many different ways that one can separate water from other materials allowing for water recycling. Centrifuges have been a key piece of equipment in the pursuit of efficient, cost-effective separation of substances of different densities. One advantage to using centrifuges is the ability to recycle and reclaim water that is being used in industrial processes that can be harmful to the environment. Using a centrifuge allows for the removal of harmful substances from water, which then provides the capability to recycle that water back for reprocessing. It also provides the opportunity to process other solids and prep them for environmentally friendly methods of disposal.
In reusing and reclaiming water from industrial processing, we are able to accomplish many different things such as prevention of contamination of nearby water sources which is crucial in limiting our impact on the environment. When accomplishing this we can also improve the quality of wetlands, provide cleaner future water supplies and create better environments for wildlife. In some applications, the recycled water can contain properties that are beneficial to irrigation and fertilizing.
The awareness for sustainability in freshwater is continually growing globally. With the right mindset and use of technology we can re-use the use of water and increase the reuse of water in industrial applications.
