The combined DL.FT lamella clarifier and drum filter is designed to offer an integrated water treatment solution, combining two of the most effective technologies in water purification. Its compact design means that it can also handle high flow rates during rainy periods without the need for a large machine. Whether in terms of materials, processing capacity or functional additions, every aspect of the system can be designed to align with the specific requirements of your project. In order to best define these specifications and provide you with a detailed proposal including an accurate quotation and 3D drawing, it’s important to fill in our design form.

The two technologies are integrated to ensure a smooth transition of water between the settling and filtration stages. An internal by-pass makes it possible to intervene on either piece of equipment without stopping operation. The large water storage capacity at the filter outlet is ideal for feeding a water reuse skid or for supplying industrial water equipment. A disinfection system can also be installed. To avoid the need to build an all-water system, an internal sludge collection tank can be integrated into the combination. To avoid the need to build an all-water system, an internal sludge collection tank can be integrated into the combination. This combined clarifier-filter allows :

  • efficient removal of organic particulate matter
  • finer filtration at the STEP outlet, enabling discharge
  • better absorb hydraulic loads, particularly during peak flows in rainy periods

In the tabs below, you’ll find some of the features specific to clarifier-filters. Here’s an overview of the various possible combinations of lamella clarifier and drum filters:.

Advantages of decantation-filtration technology

  • Complete treatment: The DL.FT offers end-to-end water treatment, combining lamella decantation to remove coarse particles and drum filtration to remove finer impurities.
  • Improved water clarity: The dual action of decantation and filtration ensures exceptionally clear water.
  • Space optimization: Integrating the two systems into one reduces the required footprint, ideal for installations with limited space.
  • Lower operating costs: The combined efficiency of the system reduces operating and maintenance costs.
  • High performance: the combination ensures superior processing performance compared to using each system individually.
  • Simplified installation: installing the combined system is simpler and less costly than installing two separate systems.
  • Adaptability to different water qualities: the combined system can effectively treat a wide range of water qualities, making it adaptable to different applications.
  • Energy efficiency: Thanks to the integrated design, the system uses energy more efficiently.
  • Easy maintenance: the combined system facilitates access for maintenance and cleaning, reducing downtime.
  • Durability and reliability: The handset is made from robust, 100% recyclable materials.

Benefits specific to 1h2o3

  • Enhanced filtration and decantation: This combination ensures effective removal of particulate pollution, down to MES <15 mg/L, even in the event of strong hydraulic variations.
  • Low maintenance: The combination of the two systems minimizes overall maintenance, thanks to features such as anti-clogging lamellae and a simple, robust drive system in the drum filter.
  • Water savings: the combined unit optimizes water use by recycling treated water for filter washing, making treatment more ecological and economical.
  • Robustness and durability: The combination of corrosion-resistant materials and robust construction ensures a long service life for the entire system.
  • Flexibility and customization: With numerous mesh size options for filters and adjustable features for decanters, the system can be adapted to specific needs.
  • Easy monitoring and control: the ability to monitor the system via PC or smartphone makes it easy to manage and optimize the treatment process.
  • Optimized space and storage: The efficient use of space thanks to the compactness of the combined system allows better layout and utilization of facilities.
  • Complete treatment: The combined system ensures complete water treatment, from initial sedimentation to fine filtration, for superior water quality.
  • Environmental compliance: The system meets strict water treatment standards, ensuring compliance with environmental regulations.
  • Easy maintenance and access: With components designed for easy maintenance, including removable lamella blocks, the combined system simplifies maintenance operations.
