Water Recycling Method Source: https://www.edwardsaquifer.net/waterrecycling.html [Reproducing it here for study purpose] Step 1: Physical Systems Physical processes are the first step in the water recycling process.  These include screening, grit removal, and clarification. Raw sewage passes through bar screens which are simply metal rods immersed in the influent flow to separate large objects such as sticks and rags from the water.  They are used to protect pumps and other rotating mechanisms further in the treatment process.  After the water passes through bar screens, it enters a grit removal system.  Here the influent flow is slowed and a mechanical separation of sand and gravel is achieved by systems such as addition of air or inducement of a vortex. Primary clarifiers allow further slowing of the wastewater so that settleable organics precipitate to the bottom while fats, oils, and greases float to the top.  These physical processes remove a...

Ambitious Guardians of H 2 O Water Conservation in Karnataka Source: http://www.indiawaterportal.org/articles/waternama-collection-traditional-practices-water-conservation-and-harvesting-karnataka   [Briefly Reproduced here for study purpose.] Archaeological evidence shows that the practice of water conservation is deep rooted in the science of ancient India. Excavations show that the cities of the Indus Valley Civilisation had excellent systems of water harvesting and drainage.  I ndia have placed utmost importance to the construction of tanks. The rock inscriptions as well as Kaifiyats confirm this. The Puranas too uphold the significance of tanks. Bronze Age and the Megalithic Age, the people of South India were regarded as leaders in constructing water-harvesting systems, especially at places where rivers were not present Historical evidence indicates that as early as 300 B.C. the communities of Karnataka knew the technique of constructing tanks as well a...

Milestones of the global water crisis – world Source: https://www.worldvision.org/clean-water-news-stories/global-water-crisis-facts (Reproduced for study purposes) There’s nothing more essential to life on Earth than water. Yet, from Cape Town to Flint, Michigan , and from rural, sub-Saharan Africa to Asia’s teeming mega cities, there’s a global water crisis. People are struggling to access the quantity and quality of water they need for drinking, cooking, bathing, hand washing, and growing their food. Amazing progress has been made in making clean drinking water accessible to 2.6 billion people in developing countries from 1990 to 2015. Yet there are still many opportunities to multiply the benefits of clean water through improved sanitation and hygiene education. The United Nations recognizes the importance of addressing the global water crisis each year on World Water Day, March 22. Globally, 844 million people lack access to clean water. Without clean, easily ...
