Cascade Baffle Water Tank - What is it about?

What Is A Cascade Baffle Tank?

The cascade system of tanks is a unique and traditional mechanism and is used to capture and utilize rainwater. 

This means that water is available during the dry season, helps avoid floods and supports everyday living. 

Cascade tank, also known as hot well, is a part of boiler feed water system. Water is pumped into the cascade tank from the feed water tank. The boiler water is treated in the cascade tank and the return from the steam heating system is also connected to the hot well.

The main roles of a baffle in a shell and tube heat exchanger are to: 

* Hold tubes in position (preventing sagging), both in production and operation. 

* Prevent the effects of steam starvation, which is increased with both fluid velocity and the length of the exchanger. 

* Direct shell-side fluid flow along tube field, the role of the cascade is to collect water from the condenser. 

One main importance is to give employees something to strive for and it is also used for storing water.


Effects of Baffle Configurations on the Performance of a Potable Water Service Reservoir

Because a baffle is a device used for altering the flow pattern in a tank, the use of a baffle wall was considered to modify an existing potable water service reservoir operating as a storage tank to achieve better water quality. Therefore, it is of great interest to study the effects of baffle configurations on the performance of the service reservoir.  The flow pattern and chlorine in the baffle tank, the results of this study show a dual effect of the baffles located at the flow recirculation region. On one hand, it can break up the vortex to shorten the flow path. On the other hand, the velocity magnitude of the fluid is reduced after flowing past the baffle, because of the impact and viscous forces induced by the baffle. These two effects are contradictory to one another in enhancing the performance of the service reservoir acting as a storage tank, because short flow path and high velocity magnitude is preferred to achieve better water quality. The overall effect of baffling is found to be counter-productive in this feasibility study. The results also demonstrate the importance of studying the effects of baffle configurations under dynamic flow condition.


Effects of cascade and baffle in the treatment of water

It provides minimum volume of the recirculation region and also dissipates the kinetic energy, creates uniform flow field in the tank and finally the hydraulic efficiency of the sedimentation tank will be improved.


Porous baffle effects on water

It makes the water in the tank to be laminar (when a fluid flows in parallel layers with no disruption) as the flow velocities decrease due to viscous effects and internal resistance in the porous zone.it also increases the hydraulic efficiency of the conventional design from poor to good.
