In California, less than 1% is recycled from water supply. This is mainly due to the lack of education of the necessity of recycling and reusing water. Moreover, there’s always a concern about safety measurements required to recycle water. It’s very critical that the recycled water retains its sanitation.
Reusing and recycling water lessens the burden on natural resources and makes people able to share these resources with nature itself. Especially in countries where natural resources for water are limited. In many parts of the world, people assume that an abundant supply of clean water is always available.
Nature itself has been recycling water for millions of years. So nature is the ultimate recycler of water, called the hydrologic cycle. The overall amount of water on the planet never changes; it’s only the distribution of it that varies; whether it is liquid form, vapor, or solid. Nature has also its own filtration system. As water passes through the soil, the soil filters the water and allows the clean water to settle underground. Moreover, rocks and sands in riverbeds remove impurities of water as it moves downstream. So, every drop of water we’ve ever used has been recycled over and over …show more content…

The primary treatment includes the screening process in which large objects are removed. Then, grit removal takes place; where small inorganic materials, such as sand, gravel etc. are forced to be settled and then be removed while leaving the organic materials suspended in water. After that, water is left for heavier materials to settle down in sedimentation tanks. The secondary treatment takes place directly after the primary, where bacteria and microorganisms are used to remove the organic materials; therefore, oxygen depleting pollutants. Then, sedimentation takes place again to remove solid materials. Although water was filtered out of the organic and inorganic wastes; colors, metals and nutrients are removed by the tertiary treatment. Nitrogen is removed by nitrogen removing bacteria while phosphorous is removed by phosphorous removing bacteria or it can be converted to salts, kept to settle down and then removed by some chemicals such as aluminum or ferric. When the wastewater treatment is done, disinfection occurs to disinfect effluent before it’s discharged; and this happens using disinfectants such as chlorine gas or sodium hyper chloride, or by the use of disinfecting agents such as ultraviolet light or
