Discussion
Situation
A small municipality in the Harz Mountains in central Germany was planning to modernise its municipal wastewater treatment plant. The reason for this was the increased population growth. During the construction phase, which was to last 12 months, the municipality was looking for an interim solution to ensure wastewater treatment. It asked an engineering firm, which approached PPU Umwelttechnik GmbH.
Problem
The challenge was that the municipality was no longer achieving its prescribed discharge values. These are a COD of 150 mg/l and a BOD of 40 mg/l. It therefore decided to replace the entire plant. During the construction phase, the municipality looked for a temporary interim solution. It was important for this to be available quickly, to quickly start its purification performance and to achieve the required discharge values.
Solution
The ideal solution for this project is a ClearFox® containerised wastewater treatment plant. This is customised to the needs of the municipality and is particularly suitable as a leasing system.
All treatment processes can be accommodated in the containers. The first container consists of a buffer with screening. The second container contains the fixed bed biological reactor with connected lamella clarifier. The systems leave the production facility of PPU-Umwelttechnik GmbH in Bayreuth fully operational. Thanks to the centralised production and compact design of the Clearfox® container solutions, the wastewater treatment plants are quickly ready for use, efficient and flexible.
The leasing option saves the local authority an additional high one-off payment and provides a customised solution for a fixed period. However, this can be customised if the leasing period is extended due to delays in construction work.
PPU Umwelttechnik GmbH put the containerised wastewater treatment plant into operation at the beginning of 2024. Since then, it has been operating smoothly and ensuring wastewater treatment during the construction phase.
