With its compactness and projected surface of 26 m², the lamella clarifier DLME-M is suitable for outdoor use. It is supplied with a removable hood which allows:

  • to prevent seaweed growth in the weir channel,
  • prevent the introduction of external debris such as dead leaves

This reinforced hood can support the weight of a man, is non-slip and easy to handle.

The whole outer structure is made of high quality honeycomb plates with UV protection, which keeps the heat in and resists UV attacks.

You will find below some of the specific characteristics of lamella clarifiers and the advantages of the DLME-M:

Benefits of lamella technology

  • Ground surface area <90%: Lamellar settling technology allows the water to be treated on a surface area 10 times smaller than a traditional clarifier.
  • No moving parts: All lamella clarifiers are fixed. Without moving parts, they require little maintenance and servicing.
  • Hydraulic overloads: Lamella clarifier is a faster clarification process. A lamella clarifier can operate with peak flow rates 2 to 4 times higher than traditional clarifiers.
  • No chemicals: Thanks to their simple design, lamella clarifiers work without chemicals. Therefore, they are able to act as a pre-treatment for delicate membrane processes for example.
  • Flocculation coagulation: Performance can be improved through the action of flocculants and coagulants. These chemicals allow to bind the particles together. As they are heavier, they settle better, which increases the purity of the treated water, even improving the removal of phosphorus when the coagulation is FeCl3.

Specific advantages of the lamella clarifier 1h2o3

  • Smoothed anti-clogging lamellas: All our clarifiers are equipped with smoothed PVC lamellas, allowing a better sedimentation and offering in addition a self-cleaning effect
  • Lamellae thickness: All our clarifiers are equipped with 3 mm thick lamellae. This thickness makes the structure much more resistant to clogging due to lack of maintenance and prevents the risk of collapse.
  • Storage of industrial water: The bottom of the lamella clarifier is designed to store the treated water. It is useful when you have a sifter to feed at the head of the plant for example.
  • Regulation-compliant inclination: The 60° inclination satisfies most regulations/recommendations for lamellar settling.
  • Corrosion resistant: The materials used in every lamella clarifier are corrosion resistant, which significantly improves the life span of the equipment.
  • Separate collection of floating sludge: With our twin weir channel, the  sludge can be collected separately:
    • – settling water: treated water
    • – floating sludge: the floating fraction on the surface of lamella clarifiers which, if not collected separately, reduces efficiency in TSS, COD, BOD5.
  • High quality and recyclable materials: Unlike fiberglass, all materials used in our equipment are 100% recyclable. We hope that you will return the equipment at the end of its life!
  • Drinking water conformity: Some countries require specific materials for drinking water applications (NSF-61, ACS, DVGW, SVGW..). We can adapt the materials of our lamella clarifiers to meet your specific regulations.
  • Quick drain: It is required to clean the lamellas of the lamella clarifier. You can lower the fluid level with the sludge drain. And to save time, a “quick drain” pipe can be added under the lamellas.
  • Heat insulation: Tall our clarifiers are surrounded by a honeycomb envelope > 50mm, which allows to keep the heat while providing a great structural resistance.
  • Removable lamella blocks: Some industries (IAA, aquaculture) have to clean the structures periodically, and therefore have access to the bottom of the structure. All 1h2o3 lamella clarifiers have removable lamella blocks. This way, the clarifier is fully reachable and it is even more convenient to clean the lamellae!
  • Reinforced clarifier bottom: Some sandy waters have a higher abrasion potential, and it is better to reinforce the clarifier bottom in these cases.
