  • The influence of lamellar settler in sedimentation tanks

    Sedimentation tanks constitute one of the most common types of water-treatment processing units. They are used in water-treatment facilities in order to remove the majority of the settle-able solids by the mechanism of gravitational settling. Lamella gravity settlers are often used in water treatment to make rectangular tanks more cost-effective.

    Sedimentation basins are impoundments placed on earth disturbance sites to capture and treat sediment-laden runoff. The purpose of sedimentation basins is two fold (1) to capture and detain the sediment-laden runoff originating from the site thus providing an opportunity for the suspended sediment to settle from the water and (2) to provide storage for the captured sediment.
