Settling Tank In Wastewater Treatment, Water Sedimentation Tank

Settling Tank In Wastewater Treatment

Primary sedimentation tank is composed of a reaction mixer, a packing area and a clear water area, and can be equipped with a dosing device to remove of some difficult to degrade organic pollutants. We can customize according to the quality of sewage influent water, flow rate, concentration of suspended solids in the sewage and your process requirements.

● Efficient purification
● High space utilization
● Simple operation and maintenance

WE OFFER DIFFERENT SEDIMENTATION TANK TYPES FOR YOU

Rectangular Settling Tank

——

Rectangular settling tank has a rectangular shape and are commonly used in small to medium-sized water treatment plants. They allow for efficient removal of settleable solids through gravity settling.

Circular Settling Tank

——

Circular settling tanks have a circular or oval shape and are suitable for larger treatment plants. They are often used in both water and wastewater treatment processes. The circular design promotes even distribution of flow, optimizing the settling process.

Inclined Plate Settler

——

Inclined plate precipitator utilizes a series of inclined plates or inclined tubes to increase the effective precipitation area in the tank. This design enhances the efficiency of solid particle removal and is particularly useful in compact installations.

THE ADVANTAGES OF SETTLEMENT TANK

Particle Removal

Settlement tanks effectively remove suspended particles and solids from water or wastewater. This process involves allowing the particles to settle to the bottom of the tank by gravity.

INQUIRY NOW

Sludge Removal

Settlement tanks facilitate the separation of sludge (settled solids) from the liquid. This allows for the removal of sludge from the tank, which can be further processed or disposed of in an environmentally friendly manner.

Pre-treatment for Filtration

Settlement tanks are often used as a pre-treatment step before filtration processes. Removing larger particles through settlement can prevent clogging and enhance the efficiency of downstream filtration systems.

INQUIRY NOW

Preventing deposits in downstream processes

Settlement tanks prevent the accumulation of sediment in pipes, pumps, and other equipment in downstream processes. This helps maintain the efficiency of the entire water treatment system.

THE DIFFERENT APPLICATIONS OF WATER SETTLING TANK

Wastewater Treatment

Sedimentation tanks are extensively used in municipal water treatment plants to remove suspended solids, sediment, and other impurities from raw water, which ensures the production of clean and safe drinking water.

Mining and Mineral Processing

In mining operations, sedimentation tanks are employed to settle out and separate solid particles from water used in ore processing. This helps to recover valuable minerals and reduce the environmental impact of wastewater discharges.

Pulp and Paper Industry

Water settlement tanks are used in the pulp and paper industry to remove suspended solids and fibers from process water before it is discharged or reused in the manufacturing process. Greatly improves the utilization rate and environmental protection.

Power Plants

Power generation facilities, particularly those using cooling water systems, use sedimentation tanks to remove suspended solids and impurities from the water. This helps maintain the efficiency of heat exchange equipment.
