What type of tank is utilized in the batch purification process?

In the batch purification process, the purpose is generally to separate different components of a mixture based on their physical or chemical properties. One common type of tank used for this purpose is a settling tank.

A settling tank is designed to allow heavier particles or immiscible liquids to settle at the bottom under the influence of gravity, facilitating the separation of contaminants from the desired product. This is particularly important in batch processes, where materials are processed in discrete quantities, allowing for effective purification of each batch through sedimentation.

By allowing the mixture to sit undisturbed, the heavier particles can settle, leading to a cleaner effluent that can be further processed. This is integral to ensuring high purity levels in the final product, making the settling tank a critical component of the batch purification process.

While other types of tanks like separation tanks and holding tanks are also used in various contexts, a settling tank is specifically tailored for the batch purification processes where sedimentation plays a key role.
