Kierrätysveden

Kierrätysveden, often translated as recycled water or reclaimed water, refers to treated wastewater that has been purified to a level suitable for various reuse purposes. The treatment process typically involves several stages, including physical filtration, biological treatment, and disinfection, to remove contaminants and pathogens. The quality of recycled water can vary depending on the intended use, with higher standards for potable reuse and lower standards for applications like irrigation or industrial processes.

The primary goal of recycling water is to conserve fresh water resources, especially in regions facing scarcity or drought. By reusing treated wastewater, the demand on natural sources like rivers, lakes, and groundwater is reduced. This practice is particularly beneficial for agriculture, which is a significant consumer of water, allowing for irrigation of crops.

Beyond agriculture, recycled water can be utilized for non-potable urban uses such as toilet flushing, landscape irrigation in parks and golf courses, and industrial cooling or processing. In some advanced systems, recycled water is purified to drinking water standards, a process known as direct or indirect potable reuse, though this is subject to strict regulations and public acceptance. The responsible management and application of recycled water play a crucial role in sustainable water management strategies.
