It is a chemical process that involves adding a coagulant to the water, which causes the particles to clump together and form larger particles called flocs. These flocs can then be removed from the water by sedimentation or filtration.<\/p>\n<p>The detention period in coagulation tanks is the amount of time that the water is allowed to stay in the tank before it is discharged. The detention period is important because it allows the coagulant to react with the particles in the water and form flocs. The longer the detention period, the more time the coagulant has to react with the particles, and the larger the flocs will be.<\/p>\n<p>However, the detention period cannot be too long, or the flocs will start to break down <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> and the particles will be released back into the water.
