The tube settler works by utilizing the principles of laminar flow and gravity settling. The wastewater or water to be treat enters the settling tank and flows through the incline tubes of the tube settler. The tubes are typically made of plastic and are arrang in a parallel configuration.
As the water flows through the tubes, the suspend solids present in the water begin to settle due to gravity. The incline tubes provide a longer settling path, allowing for more time for the solids to settle. The settl solids slide down the tubes and accumulate at the bottom of the tank. The clarify water exits the Lamella Clarifier from the top and can be further treated or discharge as per the required standards. The sludge collect in the sludge hopper is periodically remove for further treatment or disposal.
After the flocculation stage, the water proceeds to the settling stage within the same tank. The velocity of the water flow is reduc, allowing the formed flocs to settle to the bottom of the tank by gravity. The settle particles, along with the form sludge, are collect and remove as sludge from the tank.
The clarify water, known as the supernatant, is collected from the upper part of the tank, typically using a collection mechanism or launder system. It is then further treat through processes such as filtration, disinfection, or other advanc treatment methods to achieve the desire water quality.
