In the greater Kuala Lumpur area, Malaysia’s largest waste management company, Kualiti Alam Sdn. Bhd, operates a landfill for the disposal of residual materials from several waste management companies. Due to the wide range and high degree of contamination of the residues and concentrates, also from the industry, the leachate of this landfill is very complex and difficult to treat.
The pandemic brings along new challenges, like, for example, the commissioning of state-of-the-art wastewater treatment plants in distant regions in times of travel restrictions: another task that WEHRLE has successfully mastered!
The plant constructor WEHRLE with headquarters in Emmendingen in the South-West of Germany has obtained the contract for the design, construction and commissioning of a wastewater treatment plant for the treatment of highly loaded leachate from a municipal solid waste landfill in Jombang on the Indonesian island of Java.
With the change of the fertilizer regulation, the spreading and use of agricultural fertilizers is further limited. Farmers and biogas plant operators are often left with only costly temporary storage and expensive external disposal since the processes currently available on the market do not meet the requirements and involve high operating costs.
Environmentalists have been crying hoarse for long over the potential risks of pharmaceutical pollution. With water playing an integral part in the pharmaceutical manufacturing lifecycle, active pharmaceutical ingredients in wastewater, when discharged to the environment, may lead to the creation of multi-resistant germs in rivers and lakes. Treating pharmaceutical wastewater proves to be a challenge, and pharma producers are under the radar to contribute to improved water stewardship and take concrete measures to eliminate contaminants from their production wastewater. Against this backdrop, the German-based WEHRLE-WERK, with profound expertise in treating complex wastewater from the production of pharmaceutical drugs, can help pharmaceutical companies achieve this reliably and cost-effectively.
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.
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.
