Cooling wastewater streams particularly during hot summer conditions is crucial. Wastewater discharged from industrial processes must be cooled to a maximum of 34°C to ensure the effective functioning of biological treatment processes and to comply with local environmental regulations. 

Failure to meet these temperature limits can result in warnings, mandatory process changes, or even shutdowns due to thermal pollution or biochemical oxygen demand (BOD) breaches. The whitepaper presents case studies demonstrating how temporary cooling solutions, such as mobile cooling towers and heat exchangers, assist industries in maintaining compliance, preventing corrosion, and avoiding operational shutdowns while optimising profitability.
