Coagulation and flocculation practices are essential pretreatments for many water purification systems.. In conventional coagulation-flocculation-sedimentation, a coagulant is added to the source water to create an attraction among the suspended particles. The mixture is slowly stirred to induce particles to clump together into “flocs.” SAFE DRINKING WATER IS ESSENTIAL The growing population also needs more food. In many parts of the world, water is increasingly being used for agriculture, which competes with household water use. Water supplies face environmental pressures as well as human ones.

The state of drinking water supplies can be quantified by four important characteristics: quality, quantity, reliability, and cost.

In various locations, the costs of water supply are subsidized by government institutions. In some cases, this is an essential tool in providingwater to poor

In this online activity, you can explore a sequence by designing and sending short DNA "probes" through part of the human genome. The sequence of nucleotides in a gene gives it meaning by storing the instructions for building the other molecules necessary for life. These instructions are read as a string of A’s, T’s, G’s, andC’s, such

The churning of water induces particles to collide and clump together into larger and more easily removable clots, or “flocs.”. Flocculated water is collected in a tank and is subjected to a large infusion of tiny, pressurized air bubbles.
