WebA settler is a primary treatment technology for wastewater; it is designed to remove suspended solids by sedimentation. It may also be referred to as a sedimentation or settling basin/tank, or clarifier. The low flow velocity in a settler allows settleable particles to sink to the bottom, while constituents lighter than water float to the surface. WebGenerally, three to seven reactor stages are provided in one end of the reactor, and an acid settler (or decanter) is provided in the other end. Each stage is partially filled with liquid (an acid-hydrocarbon suspension), and a gas mixture is above the liquid. This process is widely used, and additional reactors have recently been installed in ... reading test ielts academic practice
