The term "water reuse" is generally used interchangeably with terms such as wastewater reuse, water reclamation, and water recycling. A definition by the USEPA states: "Water reuse is the method of recycling treated wastewater for beneficial purposes, such as agricultural and landscape irrigation, industrial processes, toilet flushing, and groundwater replenishing (EPA, 2004)."
Besides recycling water, it also reuses the heat of the water (which would otherwise be lost). [ 24 ] [ 25 ] Contrary to the popular view that the most effective way to save water is to curtail water-using behavior (e.g., by taking shorter showers), [ 26 ] experts suggest the most efficient way is replacing toilets and retrofitting washers; as ...
It thus converts it into an effluent that can be returned to the water cycle. Once back in the water cycle, the effluent creates an acceptable impact on the environment. It is also possible to reuse it. This process is called water reclamation. [1] The treatment process takes place in a wastewater treatment plant.
The Biden administration announced $179 million for wastewater recycling projects, boosting plans to build the nation's largest plant in Southern California.
It is also called wastewater reuse, water reuse or water recycling. There are many types of reuse. It is possible to reuse water in this way in cities or for irrigation in agriculture. Other types of reuse are environmental reuse, industrial reuse, and reuse for drinking water, whether planned or not.
This contaminated water can be disposed of, along with the sludge from the sedimentation basin, or it can be recycled by mixing with the raw water entering the plant although this is often considered poor practice since it re-introduces an elevated concentration of bacteria into the raw water. Some water treatment plants employ pressure filters.
Reclaimed water can be reused for irrigation, industrial uses, replenishing natural water courses, water bodies, aquifers, and other potable and non-potable uses. These applications, however, focus usually on the water aspect, not on the nutrients and organic matter reuse aspect, which is the focus of "reuse of excreta".
The human sewage and the process waste from the manufacturing industries are the two major sources of the waste water. In Thailand, the total volume of the wastewater from industries is much greater than that of the domestic sewage. [2] As a result, an effective method is needed.
