1 TMCI Padovan Intercontinental patent pending DYNAMOS

2 DYNAMOS TMCI PADOVAN SPA presents DYNAMOS to the wine industry: the first rotating dynamic cross flow filter with innovative back-pulse system, covered by intercontinental patent.

3 DYNAMOS Energy Saving High Solids Dynamic Crossflow Filtration: from lees to the bottle! Filter-aid free alternate to the vacuum, press-filters and conventional crossflow filters for juice and wines lees, as well as for all liquids with high solids content Principle used is the Dynamic Crossflow Filtration applied to rotating disks. This avoids plugging and allows for a self cleaning process; disks are open and fully inspectable Innovative Back-Pulse All tests and installations proved a high quality filtrate level: solids-free juice and wine lees can be bottled directly as a traditional cross-flow filtration No Red Colour reduction (Abs at 520nm) Solids concentration up to 65%v/v No oxygen pick-up (with limited nitrogen sparging) Low energy requirement process High nominal flowrates (20-25 l/m2h) Long filtration cycles (up to 10 hours without stopping)

5 DYNAMOS TRENDS

6 DYNAMOS ADVANTAGES Dynamic Cross-Flow-Filtration provides the maximum filter efficiency In this process rotating discs generate a turbulent differential speed of the feed. This effectively prevents the development of plugging layers which obstruct filtration Extremely high cross flow velocity (high efficient cleaning of the filter surface) In rotating filters, the shear stress and flow rate are unlinked because the shear stress is a function of the rotating filter disk speed Very low energy consumption (compared to conventional cross flow techniques) Strong cross flow effect Uniform feed pressure in the membrane Very low transmembrane pressure, Controlled cake layer Minimized formation of secondary separating layers Self-cleaning effect on the membranes Compact modular design Calibrated Back- Pulse

7 DYNAMOS FLOWSHEET The membrane discs are mounted in one or two hollow shafts. The permeate penetrates through the ceramic disc and is collected and discharged inside the shaft/s. Ceramic disc rotation generates high relative velocities towards the medium to be filtered. The particularly high turbulence in the overlapping areas minimise cake formation on the membranes. In addition the centrifugal force acts on cake layers and removes them outwards continuously.

8 DYNAMOS SPECS Top view Front view In double shaft filters, the rotating stacks overlap and maximize the cleaning effect on the discs. In single shafts filters, the rotating stack is provided with a static comb to maximize the flowrate.

9 DYNAMOS DISCS Ceramic Filtering Disc Diameter: 312 mm Thickness: 6 mm Membrane Surface: 0,15 m² Material: Al2O3 or ZrO2 Porosity: 0.1 mm

10 DYNAMOS HIGHLIGHTS Cross flow velocity, flow rate and pressure are independent Cross flow velocity is at least 2-4 times higher than the speed of a tubular cross flow system. Installed power is reduced by 80% in relation to the traditional tubular cross flow systems Higher solids concentration levels, up to 65% v/v Significantly higher performance in relation to a tubular cross flow filter. The selectivity is defined by the membrane itself and not by the fouling layer Flow rate is kept even with very low product recirculation
