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...
