Emergency tank

In production facilities where significant, temporary fluctuations in wastewater load can occur, a mixing and equalization tank may be supplemented by an emergency (or "spill") tank. This tank serves to contain wastewater with exceptionally high pollutant loads or significantly atypical characteristics, thereby protecting downstream treatment stages from excessive load spikes.

Such wastewater streams are identified via automated measurement and monitoring systems located in the influent line. If critical deviations—for example, in pH levels, temperature, or organic load—are detected, the affected wastewater is automatically diverted into the emergency tank instead of entering the equalization tank.

Once the influent parameters return to within the defined operational limits, the stored wastewater can be gradually introduced into the mixing and equalization tank. This allows for the targeted mitigation of load spikes, protecting the wastewater treatment plant from overloading or potential operational disruptions.

The combination of an equalization tank, an emergency tank, and automated monitoring ensures a highly consistent and controlled influent flow. This enhances operational reliability, stabilizes downstream purification processes, and helps maintain a consistently high level of treatment performance across the entire facility.

CUSS GmbH designs emergency containment systems on an individual basis, tailored to specific production conditions, anticipated load fluctuations, and the requirements of the wastewater treatment process.
