Controlling water quality in buffer tanks and reservoirs

Buffer tanks, reservoirs and storage basins often play a central role within process water systems. Water is stored, circulated, reused or temporarily left stagnant before it re-enters the system.

Especially in these storage points, microbiological build-up can occur. CWN assesses each installation to determine whether nano cavitation can contribute to better controlled water quality in buffer tanks, reservoirs and connected piping systems.

Why stored water requires attention

When process water is stored for longer periods of time, temperature, organic load, stagnation, sedimentation and microbiological activity can reinforce each other.

In buffer tanks and reservoirs, microorganisms can accumulate in the water, on walls, on the bottom or in connected pipes. This can lead to biofilm, slime formation, contamination or recontamination.

When this water re-enters the process, the microbiological load can spread further to pipes, filters, heat exchangers, membranes or other critical installation parts.

What CWN adds

CWN applies nano cavitation as an additional physical treatment in and around storage points within the water circuit. The application is tailored to tank volume, water movement, residence time, load, existing treatment and critical connections.

  • More control over microbiological build-up in buffer tanks and reservoirs
  • Support for stored, circulating or reused process water
  • Reduced risk of recurring contamination from storage points
  • More stable water quality towards connected installation parts
  • Technical assessment of tank, flow and placement

From stagnation to active water management

Buffer tanks and reservoirs are often more than just storage. They can become a source of microbiological build-up or recurring contamination within the process water system.

CWN therefore does not only look at the tank itself, but at the role of the storage point within the complete water circuit. If CWN is technically suitable, we validate this with a pilot under practical operating conditions.

This makes it visible whether nano cavitation contributes to more stable water quality, less recurring contamination and better control over the water that re-enters the system from buffer tanks or reservoirs.

Frequently asked questions about buffer tanks and reservoirs

Short answers to frequently asked questions about stored process water, microbiological build-up and the use of CWN Free and Tube.

Why are buffer tanks sensitive to microbiological build-up?

In buffer tanks, water storage, residence time, temperature, organic load and stagnation come together. As a result, microorganisms can accumulate in the water, on walls, on the bottom or in connected pipes.

Can CWN help reduce recontamination from a reservoir?

CWN can be relevant when stored water re-enters the system and carries microbiological load or contamination with it. The impact depends on tank volume, water movement, residence time, load, placement and measurement strategy.

Does CWN replace tank cleaning or existing water treatment?

No. CWN is applied as an additional system technology. Tank cleaning, flushing, filtration, UV, oxidative treatment or other existing measures can each retain their own function within water management.

Where is CWN installed for buffer tanks or reservoirs?

That depends on the installation. Possible locations include inside the tank, in a bypass, at circulation pipes, return flows, supply lines or zones where storage, stagnation and microbiological load come together.

How do we demonstrate the impact of CWN?

We define together in advance which goals are important for your installation. During a pilot, we monitor these through measurements and practical observations, for example water quality, microbiological load, contamination, biofilm-sensitive zones, sedimentation and system stability. This makes the contribution of CWN visible within your own process water system.

Would you like to know whether CWN is suitable for your buffer tank, reservoir or process water installation? Based on tank volume, water movement, residence time, load, existing treatment and measurement data, we assess whether a pilot is technically relevant.
