Sewage Treatment Plant



Kelvin Water Technologies specially design the centrifuge, and the drive that makes the wastewater decanter particularly economical. The decanter bowl is designed to increase the volume of sedimentation in the bowl. It is also used in the solids and liquids system for complete removal from wastewater.

Decanters are used in wastewater treatment plants (WWTPs) to separate mixed wastewater into two phases (solids and liquids). They are often used in the treatment of wastewater to separate solid particles from liquid, for example in the removal of grit, sand, and sludge from wastewater. Decanters are also used in the concentration of solids, for example to reduce the volume of sludge for disposal or further treatment and are commonly used in combination with other technologies such as dissolved air flotation (DAF) and chemical treatment to further reduce the amount of contaminants in wastewater.

Decanters work by spinning wastewater at high speed in a cylindrical container. The centrifugal force created by the spinning separates the heavier solids from the lighter water, pushing the solids to the walls of the container. The concentrated solids are then removed through a discharge pipe at the bottom of the decanter. They also has an inlet pipe at the top, which allows the wastewater to enter the container to be treated.

Decanters are typically used in conjunction with other treatment processes such as sedimentation, filtration, and chemical treatment that can be used in the treatment of both domestic and industrial wastewater and are effective in removing suspended solids, oils, and grease from wastewater.

Decanters are relatively low maintenance and require minimal operator input. They are relatively cost-effective and can be used as a standalone treatment process or as part of a more comprehensive treatment program. They are important component of any wastewater treatment system, as they help to reduce the amount of waste that is discharged into the environment.

Benefits of Decanter -

  1. Faster and more efficient sedimentation: They are designed to quickly and efficiently separate solids from liquids. The centrifugal force created by the spinning bowl causes the heavier particles to settle to the bottom of the bowl, allowing for more efficient separation.

  2. High-capacity: Decanters come in a variety of sizes, from small lab-scale units to large industrial-scale units. This allows for high-capacity processing of fluids, which is especially useful for industrial applications.

  3. Enhanced clarity: Decanters can be used to achieve a higher degree of clarity in liquids. The centrifugal force created by the spinning bowl helps to remove finer particles, resulting in a clearer product.

  4. Cost savings: Decanters can be used to reduce operating costs. By separating solids from liquids, decanters can reduce the amount of waste material produced, which can help to lower disposal costs. Additionally, they can reduce the amount of energy needed to process materials, resulting in cost savings.
