DeSiFloc - Landfill Leachate Treatment

The DeSiFloc concept for landfill leachate treatment includes a new, internationally patent-protected process which can separate the pollutants more efficiently compared to conventional processes. The main part of the new process comes into play after biological pre-treatment. The non-biodegradable or residual pollutants are targeted in the FlocFormer process and can then be filtered out of the waste water flow. The operating costs of the new process are very reasonable.

By using FlocFormer, the landfill leachate treatment process is more consistent in terms of processing and costs compared to conventional treatment. Throughout the entire system, the focus is on removing all pollutants (apart from biodegradable nitrogen compounds) efficiently from the waste water using the FlocFormer process.

• Investment is only around 50 % compared to decanter applications.
• Energy consumption is only around 12.5 % compared to decanter applications
  (approx. 20 kW against approx. 2.5 kW).
• The service life of the active carbon filter is increased by 2.5 times (less personnel, reduced downtimes).
• The COD input value in the active carbon filter almost reaches the discharge limit already.
• The active carbon filter is reduced almost solely to a monitoring capacity (60 % lower active carbon costs).
• Noise pollution from the machines is significantly reduced (thanks to the low-speed FlocFormer and disc thickener).
