The onset of winter brings not only picturesque landscapes but also significant challenges to the wastewater treatment processes in Szczecin. As temperatures drop, microorganisms critical to the purification of sewage face severe risks. If not properly managed, these conditions could lead to dangerous consequences for the entire treatment system. The local authority emphasizes the need for special procedures to ensure efficient functioning during this period.
As the temperatures approach the freezing point, bacteria responsible for breaking down toxic substances in wastewater become sluggish. This necessitates additional care and attention to the microorganisms that work tirelessly underground, similar to how humans adapt to the cold. During winter, when the temperature in sewage treatment tanks can fall to around 12 degrees Celsius, the biological activity of these organisms diminishes significantly, potentially disrupting the entire wastewater treatment process.
The Zakład Wodociągów i Kanalizacji (ZWiK) in Szczecin is actively monitoring and adjusting the treatment processes to counteract the adverse effects of low temperatures. According to the spokesperson for ZWiK, the challenges are twofold: not only do low temperatures hinder the bacteria’s work, but additional runoff during winter months carries excess salt and pollutants, further compromising the treatment process. As a response, the team increases the concentration of bacteria during these chilly months to maintain efficiency and ensure the treatment process remains effective.
Moreover, autumn introduces an additional complication in the form of a new kind of bacteria that acts as a parasite on the beneficial microorganisms. Managing these pathogens requires careful monitoring and occasionally the application of specific treatments to maintain the health of the bacterial population essential for effective sewage treatment. This proactive approach is crucial to ensure that waste processing continues seamlessly, safeguarding the environment and maintaining public health in Szczecin.
