In some cases, the installed SBR process does not suffice to achieve the required treatment objectives. There is a variety of possible reasons: changes in the characteristics of the actual wastewater compared to the ones considered in the design (concentrations, flow rate), modification of the discharge requirements, incorrect process design, etc.
In spite of delays during the authorization process as well as the late approval of national funds due to Covid-19, WEHRLE has been awarded the contract for the construction of a wastewater treatment plant in Poland.
October 2020 – WEHRLE has been chosen to build a leachate treatment plant in Poland. For WEHRLE, an experienced plant constructor and wastewater expert, this is a special plant construction project:
Make new from old – WEHRLE integrates a new leachate treatment plant in an existing system with beneficial advantages for the operator.
The landfill of Marston Vale, a small town near Bedford, treats approximately 450 m3 of leachate per day, consisting of the leachate produced on the landfill itself as well as on many other landfills, disposed of by tankers every day.
New paths, different perspectives – since 1860, today and in the future
This year, WEHRLE-WERK AG is celebrating the 160th anniversary of the company, which was founded by Wilhelm Wehrle as “Mechanical Workshop and Boiler Shop” in 1860. At that time, the factory was located on the outskirts of Emmendingen in the South-West of Germany. Today, it is located in the center of the town.
Pesticides have - naturally - a direct impact on ecosystems. This impact is increasingly considered as a critical factor in many countries, because pesticides act not very specific and are often persistent. Moreover, they are transferred from agricultural areas by the water path to other natural areas, where they continue having an impact. Increasingly, pesticides are also found in drinking water and pose a health risk for the general public.
After 18 years of operation, the MBR BIOMEMBRAT® leachate treatment plant of the Lloret de Mar Landfill has been extended and upgraded to Zero Liquid Discharge (ZLD).
WEHRLE-WERK AG based in Emmendingen is supporting the Medical Center – University of Freiburg in modernizing its own thermal power station and increasing its energy efficiency by installing a new steam pressure boiler. WEHRLE developed, manufactured and assembled the new boiler including complete burning system and control technology. The main advantages of the new boiler are its optimized operation and low nitrogen emissions.
A sewage sludge mono-incineration plant for the decentralized disposal of 3 t/h of sewage sludge located in the District of Straubing-Bogen (Lower Bavaria) is currently in process of authorization. The process technology for the fluidized bed plant with a capacity of 3.75 MWth has been further developed to generate quality ash particularly rich in phosphorus and with a low content of pollutants, which facilitates further processing into fertilizer.
With more than 350 references in more than 45 countries throughout the 5 continents, they guarantee their experience as an engineering company, technology supplier and service provider for the treatment of high-load wastewater and waste recovery.
Robert Körner, Head of Division Marketing & Strategic Sales, tells us about the solutions WEHRLE offers to the water treatment industry.
On behalf of the German Federal Ministry of Education and Research (BMBF), the Stiftverband collects annual data on research and development of the German economy focusing on education, science and innovation. Due to its diverse commitments in those fields, WEHRLE receives the "Innovative through Research" seal for WEHRLE-WERK AG and WEHRLE Umwelt GmbH.
