Introduction

Water treatment plants play a significant role in purifying contaminated or polluted water to make it safe for human consumption. One of the main components of a water treatment plant is a pressed basin or settling basin. In this article, we will discuss how a pressed basin helps in the water treatment process.

What is a Pressed Basin?

A pressed basin is a large tank used in water treatment plants to remove impurities and solid particles from water. It is commonly known as a settling basin or sedimentation tank. The tank is designed to allow water to flow slowly through it while the solid particles settle at the bottom. The settled particles are then removed, and the water flows through the next stage of the treatment process.

How does it work?

The pressed basin works on the principle of gravity. As the water enters the tank, its velocity is reduced, allowing the heavier particles to settle at the bottom. The tanks are designed with a slope in the base, which allows the settled particles to slide into a collection pit. The collection pit is emptied regularly, removing the accumulated sediment.

The pressed basin also helps in removing floating particles and oils from water. A skimming mechanism is usually installed in the basin, which collects the floating impurities and oils. The collected materials are then removed through a separate process.

Types of Pressed Basins

There are two main types of pressed basins used in water treatment plants:

Rectangular Basin: This type of basin is shaped like a rectangular tank and is usually used in smaller water treatment plants.

Circular Basin: This type of basin is circular in shape and is used in larger water treatment plants. Circular basins are more efficient as they allow a more uniform flow of water, which leads to better sedimentation.

Advantages of Pressed Basins

Pressed basins have several advantages in water treatment plants:

They are cost-effective and easy to operate and maintain.

They can effectively remove solid particles, oils, and floating impurities from water.

They can effectively remove up to 90% of suspended solids from water.

Conclusion

A pressed basin is an essential component of a water treatment plant. It allows the removal of solid particles, oils, and floating impurities from water, making it safe for human consumption. The design and type of basin used depend on the size of the treatment plant and the amount of water that needs to be treated regularly.
