Skimming tanks.<\/p>\n<p>Grease and fatty oils are removed in skimming tanks by skimming, which is the process of removing floating material from the surface of a liquid. Skimming tanks are typically rectangular or circular tanks with a sloping bottom. The sewage enters the tank at the top and flows down the sloped bottom. As the sewage flows, the grease and fatty oils float to the surface and are skimmed off.<\/p>\n<p>Grit chambers are used to remove grit, sand, <div class=\"telegram-channel-container\">\r\n        <a href=\"https:\/\/t.me\/pscnotes2025\" target=\"_blank\" class=\"telegram-channel-button\">\r\n            <span class=\"telegram-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 496 512\">\r\n                    <path fill=\"white\" d=\"M248,8C111,8,0,119,0,256s111,248,248,248s248-111,248-248S385,8,248,8z M362,177L320,367c-3,14-10,18-20,14l-56-41l-27,26 c-3,3-5,5-10,5l4-63L323,196c5-5-1-7-8-3l-98,62l-42-13c-9-3-10-9,2-14l162-63C351,160,365,164,362,177z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Join Our Telegram Channel\r\n        <\/a>\r\n    <\/div> and other coarse material from sewage.
