6 Things to Know About Water Recycling
Drought is a major problem in the modern world, and many regions are turning to water recycling to produce reclaimed water in order to fight the problem. That policy offers a lot of benefits to society, but it can also be confusing to people who don’t have a background in the industry. It’s important for people to understand the technology on which they rely to survive, so everyone should try to learn a few important things about water recycling.
The first thing that most people want to know about water recycling is whether it is safe or not. Engineers have put a lot of effort into ensuring safety, so there are several layers of protection. The most basic one is purification. The treatment process exists to get everything dangerous out of the water. Regular testing ensures that the purification process is working as it should, and adds some extra evidence that the water supply is safe. Usage patterns can also provide protection. While some areas do use reclaimed water for drinking, most prefer to use it as an industrial coolant, for watering plants, or for other uses where it would be safe even if it had not been thoroughly purified.
2. Recycling Water at Home
Many people recycle their own water at home, usually through a gray water system. Gray water refers to water that has been used but has not been exposed to contaminants that render it unsafe for all uses. For example, water that has been used to wash clothing is normally gray water. That can be collected and used to water plants or for a variety of other purposes, which helps to cut down on total water use in the home without sacrificing any comfort.
3. Supporting the Industrial Sector
Most industrial processes produce a lot of heat. That is a problem because the heat can damage the machines while they are in use. Engineers solve that issue by applying coolants, and water is one of the most effective and efficient options. The problem is that factories need a lot of it, and that can put strain on the water supply. Using recycled water removes that problem and makes it easier for local economies to expand without putting any strain on the water supply.
4. Protecting Ecosystems
Water has to come from somewhere. People routinely extract it from rivers and lakes, but that draws the water out of the ecosystems that depend on it. That is fine on a small scale, but it can cause serious damage when people take too much. Recycling water reduces the demand for new water sources. That eliminates a lot of the strain on the environment, and can even help damaged ecosystems to recover over time. Recycling water can even be an ecological necessity in regions that are particularly dry, especially if there are a lot of humans in those areas who need to use water.
5. Conserving Energy
Extracting water from the environment can require a surprising amount of energy. It takes a lot of power to pump water out of the ground, and the energy requirements increase over time as the water levels get lower. That is happening in most of the world because the demand for fresh water exceeds the rate at which it naturally flows back into the ground through the water cycle. The recycling process also requires energy, but there are many cases where recycling puts less strain on the power grid than taking more water out of the ground.
6. Gaining Popularity
The simple fact is that the human population is growing, and our need for water is growing at the same time. Humans simply cannot rely on drawing more and more water out of reservoirs. Most people and most governments realize this, so they are investing plenty of resources into improving and expanding the world’s water recycling systems. The technology is getting better all the time due to that funding and the experience that comes with running these systems. Water recycling is here to stay, and most people will be depending on it even more in the future than they do at the moment.
