2 Sixth generation of apparatus Sum-up of our know-how regarding separators At your service for 25 years to 1995 Aronde range Development Modular assembly of rotomoulded tanks Balance-float automatic closing device + products The largest and most important range of polyethylene separators in the market. Device accessible from the surface 1996 to 2004 Extension of the modular range Integration of the Biodeck coalescing filter with crossed structure Launching of the sizes 20, 25 and 30 l/s. The coalescence device becomes easier to clean to 2014 Ellipse range Development Optimisation of the volume dedicated to the treatment. Useful volume = total volume + products The inlets, outlets and by-pass are now installed outside of the tank range New Development A new coalescence cell A new automatic closure device. + products Associate a simplicity of extraction and a big facility for the maintenance. Self-installed, it guarantees a perfect impermeability. A new conception of the tank A new approach on internal flows. Enables deeper installations hydr dynamic circulation in the apparatus. Collection, gathering and analysis of the data The innovation at the service of water

3 Your specialist in Water pre-treatment range focus: The oil separator An optimised access Model YH0506E A new conception of the tank New or Specific Coalesc according to the model of separator A new coalescence cell The+product 3in1 Removable module for oil separators The heart of the systeme is now completely independent of the form of the tank. 1. Sludge trap partition 2. Coalesc (coalescing filter) 3. Automatic closure device

4 + cover A lockable A new conical automatic closure device A concentration of innovations The end of too restrictive installation conditions... The TechneauSphère range has been created to be compatible with all the different installation conditions met on construction sites. Une cuve tout-terrain Type of tank Standard model Reinforced model A simplified handling 1 Installation in green area without concrete load-protection slab In presence of underground waters in contact with the apparatus Fea: 1 m Fea: 1,50 m The passage for the forklifts, integrated in the lower part of the tank make loading, unloading and handling operations easier. One person is enough! 2 In absence of underground waters in contact with the apparatus Fea: 1,50 m Fea: 3 m Fea: inlet level 3 A new approach on internal flows. A central sludge silo Installation & maintenance... new advantages in the market A cylindrical access to use standard polyethylene or concrete extension shafts (please consult us). The cover supplied has many advantages: Avoids the water filling of the apparatus during the storage. Resistance 500 kg Protects all the internal components during installation and ballast operations. Enables a direct installation in green area. For installations in presence of ground water or in hydromorphic soils, the tank has a central anchoring zone to put the ballasting concrete. We can thus avoid complicated and dangerous anchorings in the bottom of the excavation. Anchoring zone A central sludge silo Located in the same line as the manhole, it facilitates visual inspections and enables, from a lonely point of suction, a complete cleaning. This 3in1, solution, real innovation made by Techneau, can completely be removed from the tank to be checked and cleaned without any risk of discharge downstream. The structure of the Coalesc has specifically been studied to be self-supporting and to resist to cleaning operations made with high pressure washer. Côté pose

5 Sixth generation of apparatus A constant wish to innovate through our Research & Development department From the conception to the realisation, the progression of ideas... > First sketch 1 Some modelling tools perfectly adapted > The 3 prototypes 2 The TechneauSphère range, real concentration of innovations, has required more than 20 months of development. Research & Development is essential for Techneau. 5 collaborators are especially in charge of studying your needs and anticipating tomorrow s products. > Hydraulic tests 3 The Quality unit has tested and validated each step of the development before its commercialization. The main first lines of thought for this new range: An independent unit composed of the partition, the coalescence and the obturation. A tank with a higher mechanical resistance than the products actually present in the market. > Validation of the unit and of the hydraulic principle 4 Maintenance operations much more easier. > Validation on our bench test: integral immersion of the tanks during 4 months. 6 > Calculation of the mechanical resistance 5 Example of simulation with Solidworks

6 Our business sectors at water service. > Water pumping From ready-to-install to made-to-measure with integrated valve chamber, a complete range of pumping stations which answer particulars and community s needs. Made out of Polyethylene or Polyester according to the ground nature. > Water treatment Big range of oil, grease & starch separators and stormwater treatment units.
