Generally, we use the term recycling to paper, plastic, aluminum, glass, etc. But, did you know that water can be recycled as well? Be it in commercial, residential or industrial usage, water recycling practices are on the rise. Reclaimed water, also known as recycled water is wastewater that has been effectively treated for reuse. Here, in this guide, from Sintech, leading centrifugal wastewater pump manufacturers in India, we share with you the different usages for recycled water.
What is Water Recycling?Water recycling is the process of reusing wastewater. It is also known as water reuse or water reclamation. Wastewater discharged from industrial and residential zones is filtered and treated for different applications like toilet flushing, irrigational needs for agriculture, industrial processes, and even for replenishing groundwater supply. Water recycling helps in saving water – which is a finite natural resource. Besides resource savings, wastewater reclamation can also offer significant financial savings. The process of recycling water depends on the final usage of recycled water. For instance, recycling water for agriculture is simpler than recycling water for drinking needs. Generally, in industries, water is recycled and reused onsite. For instance, a paper processing industry can recycle wastewater effluents that can be used for cooling various machinery on the plant. Another typical example of recycled water is greywater. It is recycled water that is reclaimed from residential, industrial and commercial bathroom drains, sinks, and clothes washing. Generally, greywater is used for flushing toilets and for landscape irrigation. If recycled water is used for agricultural needs, it has to be ensured that it is low in sodium and is non-toxic. While recycling water via man-made systems is gaining popularity in recent years, nature has been recycling water via the natural water cycle for millions of years. Water recycling can be broadly classified into two types:
- Unplanned water recycling – It refers to the natural way of water recycling. For example, let outs from drains reach the groundwater table, after undergoing filtration naturally through various layers of sand and gravel.
- Planned water recycling – It refers to projects that make use of technology to speed up water recycling. Planned projects are generally developed to maximize available water supplies.
