4 NDCF* - The energy-saving filter Rotating filter systems: The optimized combination of centrifugal and shearing forces Optimal applications Modular design High concentration High solid concentration Viscous media Continuous concentration of recyclables Demulsification Diafiltration Photo: NDCF*-plant for treatment of fermentation residues of a biogas plant Footprint: only 9 x 1 mtr. Filter surface: 180 m²/240 m² Ceramic filter discs: 60 nm - 312/374 mm Multichannel Module Rotating Disc Module * novoflow Dynamic-Cross-Flow-Filter

5 Advantages and special properties Energy savings of up to 80 % vs. traditional cross-flow modules Compact and flexible modular design, easy scalability, inspection and maintenance friendly Highly efficient overflow and cover layer prevention due to a special combination of centrifugal (rotation) and shear (turbulence created by baffles) forces High rotation speeds up to more than 500 rpm at disc diameters of mm Operation mode A membrane stack, mounted on and rotated by a hollow shaft, inside a pressure vessel (called module) Filtration is performed from outside to inside through the membrane layer coating on the filter discs; the filtrate/permeate is collected inside the filter discs and discharged via hollow shaft Fixed baffles inside the pressure vessel generate turbulences Modular design: Easy up-scale and down-scale Automatic back-flushing Dynamic Cross-Flow-Filtration CIP-compatible NDCF* 2-15 (30 m²) 5

6 CPH* Hollow fibre module Easily scalable, high flux in the narrowest space The novoflow CPH*-plant consists of hollow fibres with identical, separating active membrane on the inner and outer side in plastic housing. The hollow fibres are temperature-stable up to 50 C. Optimal application Separation of low-concentrated particles, colloids, micro-organisms, viruses and macro molecules from industrial process waters and waste waters Policing filter CPH* Advantages and special properties Chemical resistance ( ppmh vs. free chlorine, 1000 ppmh vs. H2O2) Double protection, long operating life and reduced cleaning requirements due to active membrane layers in- and outside the hollow fibre Minimal cleaning required and long service life, by virtue of the special structure of the hollow fibre with identical, separating active membrane on the inner- and outer side Low-maintenance by secure sealing between raw- and clean water phase due to potting of the fibre socket into the synthetic module tube. Neither 0-rings nor wearing seals are used Large pressure range (including pre-pressures) up to 4-bar scan is utilized for filtration No chemically contaminated flushing waters are produced during operation Space-saving modular design due to radial assembly and dis-assembly (no additional headroom is needed) Vertical positioning for optimal air-cleaning Light modules (30 kg) can be mounted manually * Compact Potted Hollow Fibre CPH* 2-23

7 CPH* with reverse osmosis CPH* CPH* 2x CPH* 1-23 Operation mode Filtration is performed from the outside to the inside of the membrane fibres Filtration phase: Fully automatic, continuous mode of operation with cyclical back flushing Air-cleaning phase: Membranes are exposed in timing cycles to air cleaning. Contaminations are collected after air cleaning and rinsing water has been discharged Chemical cleaning: After extended operating periods a chemical cleaning step is needed to restore original filtration performance Single hollow fibre Highest security by double membrane layer (= outside and inside) Pore sizes 0,003 µm up to 0,1 µm Open module With 6000 hollow fibres Special sealing compound 7

8 EC* and ECF* For the treatment of heavy metal waste water and drinking water Process advantages Non-biological and non-chemical procedures - easy to operate Up to 70 % less sludge as compared to conventional procedures Ideal pre-processing step for UF, NF or RO-systems Produces water quality with low space demand and without moving parts Iron or aluminium electrodes replaceable EC process kills germs, viruses, protozoans and bacteria High BSB/CSB biomass, bacteria, viruses and cysts Fats and oils Metal: chrome-6, nickel, lead, arsenic, copper, zinc ECF* 5000 (5 m³/h) EC* and ECF* is an electro-chemical process Generate metal ions and electrons in contaminated water Redox reactions to break down emulsions Destabilising of colloids and suspended particles PH-value adjustment to precipitate out metals Fe ++ or Al ++ ions produce a stable flocculate Permits mechanical removal of contaminations by air-flotation Gravity settling or mechanical filtration * Electrocoagulation/Electroflotation

9 Typical applications Industrial and municipal water treatment systems Removal of heavy metals and toxins for closing the circuit Primary food industry Grey water recovery Metal refining Car- and truck-washing systems Pre-treatment for membrane filtration systems And many other applications Example: Arsenic-contaminated groundwater start after 20 sec. after 40 sec. ECF* 500 (0,5 m³/h) inlet after EC- after treatment filtration 9

12 NDCF* - Dynamic Cross-Flow-Filtration One step concentration & clarification For wine, beer and fruit juices - Filtration of the purest kind! Versatile use Clarification of must from flotation sediments Clarification of must from centrifuge discharge Sediments after fermentation yeast from the first and second self-clarification (lees) Clarification of finings Residues of Crossflow Micro Filtration (retentates) Sediments from tartaric treatment Sediments from acidification step Process: Rotary discs generate a turbulent speed inside the product to be filtered. This prevents build-up of plugging layers which reduces filtration flow. Filtration performance: 50 up to litres per hour NDCF* 2-15 (30 m²) novoflow NDCF* Filter and its excellent technology for treatment/purification of: Must unfiltered Must filtered Also for residues from the CMF (retentates) - Sediments from tartaric treatment - Sediments from acidification steps - integrated filtration of young wine is an option, as well as a filtration within a fermentation process, or as a replacement for existing clear filtration. Yield from lees about %, from fining %. Operating mode A membrane stack, mounted on and rotated by a hollow shaft, inside a pressure vessel (called module) Filtration is performed from outside to inside through the membrane layer coating on the filter discs; the filtrate/permeate is collected inside the filter discs and discharged via hollow shaft Fixed baffles inside the pressure vessel generate turbulences Modular design: Easy to enlarge or decrease Automatic back-flushing CIP-compatible * novoflow Dynamic-Cross-Flow-Filter

13 Advantages and special properties Turbidity reduction significantly below 1 NTU No additives needed, quality maintained With the use of ceramic discs, migration caused by softening agents in polymers and their potential effects on taste are eliminated Flavour conservation by smooth rotating filtration Oxygen input is largely avoided since plant is operated under pressure Easy cleaning Substantial energy savings (reduced service and operating costs) No changes in taste High durability Plant sizes of 0,5 100 m² Disc diameter 375 mm Small footprint as of 1 m² Energy consumption as of 1 KW Inert ceramic membrane NDCF* 1-5 (5 m²) 13
