In a municipality in southern Germany, the existing wastewater treatment plant with a disc submerged basin could no longer meet the limits for direct discharge. It was therefore decided to renovate the plant. To ensure wastewater treatment during the renovation, the municipality looked for an interim solution. To this end, it commissioned an engineering firm, which contacted PPU Umwelttechnik GmbH.
The municipality’s challenge was to find a temporary solution to bridge the construction phase of the actual wastewater treatment plant. On the one hand, the construction time and costs of the interim sewage treatment plant had to be kept within limits, and on the other hand, it had to be able to comply with the required discharge values. These require a COD of 90 mg/l and a BOD5 of 20 mg/l. The construction of new wastewater treatment plants or temporary discharges to nearby plants are both time-consuming and cost-intensive.
Containerised wastewater treatment plants are an ideal solution. These are suitable both as a strengthening upgrade and as a complete replacement for existing wastewater treatment plants.
PPU Umwelttechnik GmbH specialises in containerised wastewater treatment plants. It has already equipped numerous municipalities with customised wastewater treatment solutions. For this project, PPU offered two containers with a submerged fixed bed. The process is known for its high purification performance, which remains stable even when overloaded or underloaded. This is a decisive advantage, especially during periods of rain or drought.
PPU supplied two containers for a period of 6 months. These included the ClearFox® FBR process for biological treatment and the ClearFox® lamella clarifier for sludge treatment.
The leasing offer also included a purchase option after six months. As the municipality was very satisfied with the cleaning performance of the containerised wastewater treatment plant, it took over the plant completely and replaced the rotating immersion tank.
Yes, container sewage treatment plants are flexible and adaptable. Together with you, we analyze the specific requirements of your project, such as discharge values, wastewater volume and available space, in order to develop an individual solution. Thanks to their modular design, the systems can be used in both small communities and larger companies.
Installation is quick and uncomplicated. Our container sewage treatment plants can usually be put into operation within a few weeks of ordering and site preparation. Installation on site only takes a few days.
Yes, our container sewage treatment plants are designed for extreme weather conditions such as heavy rain or drought. The outer shell is extremely robust and designed for a service life of at least 20 years. Thanks to the stability of the ClearFox® FBBR system used, the cleaning performance remains constant regardless of external influences.
Our leasing offers often include a purchase option. After the rental period has expired, you can take over the system, continue leasing it, or return it. We will support you in making the decision that best suits your project economically and technically.
Our plants are designed to meet the strictest legal requirements. In the project presented, COD values of 90 mg/l and BOD5 values of 20 mg/l were easily achieved.
No, our container sewage treatment plants are low-maintenance. Regular inspections and minor maintenance work are sufficient to ensure smooth operation. We also offer maintenance contracts as an option.
