The combined lamella clarifier and DL.FT drum filter is designed to offer an integrated water treatment solution, combining two of the most effective technologies in water purification. It’s very compact, so it can also handle a high flow rate 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 is 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 allows work to be carried out 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 to equipment. It is also possible to install a disinfection system. To avoid having to build an all-water system, an internal sludge collection tank can be integrated into the combination. Three versions are available: indoor (beige), outdoor (white) or ACS drinking water (black). This combined clarifier-filter enables :

  • efficient elimination of organic particulate matter
  • finer filtration at the end of the WWTP to achieve discharges< of 15 TSS
  • better absorb the hydraulic load, particularly during peak flows in rainy periods

In the tabs below, you’ll find a number of features specific to clarifier-filter. Here is a presentation 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 lamellar 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 optimisation: Integrating the two systems into one reduces the footprint required, ideal for installations with limited space.
  • Lower operating costs: The combined efficiency of the system means lower operating and maintenance costs.
  • High performance: the combination ensures superior treatment performance compared with using each system individually.
  • Simplified installation: installing the combined system is simpler and less expensive 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 its integrated design, the system uses energy more efficiently.
  • Easy maintenance: The combined system provides easy access for maintenance and cleaning, reducing downtime.
  • Durability and reliability: The handset is made from robust, 100% recyclable materials.

Benefits specific to 1h2o3

  • Improved filtration and decantation: This combination ensures effective removal of particulate pollution, down to TSS <15 mg/L, even in the event of strong hydraulic variation.
  • Reduced maintenance: The combination of the two systems minimises overall maintenance, thanks to features such as anti-clogging lamellae and a robust single drive system in the drum filter.
  • Water savings: the handset optimises 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 customisation: With numerous mesh size options for the filters and adjustable features for the decanters, the system can be tailored to specific needs.
  • Easy monitoring and control: The ability to monitor the system via PC or smartphone makes it easy to manage and optimise the treatment process.
  • Optimised space and storage: The efficient use of space thanks to the compactness of the combined system means that facilities can be laid out and used more efficiently.
  • Complete treatment: The combined system provides 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.
