1 From Black to Clean Waters Energy efficient Decentralized Sewage Treatment

2 Former construction of septic tanks and more.

3 More than 110 years of experience Menk

4 Applications in Chile, Finnland, China

5 How does Batchpur work? 1. Filling: The pretreated wastewater is transfered to the SBR-Reactor. The load is exactly determined.

6 How does Batchpur work? 2. Aerating: Wastewater will be aerated and circulated using a compressor. The aeriation time is set by the control unit automatically and continuously. Therefore, only the necessary amount of energy will be consumed.

7 How does Batchpur work? 3. Deposit During this stage, the aeriator will be turned off. The available biomass in the container will settle. In the upper region a clear water zone will develop with purified wastewater.

8 How does Batchpur work? 4. Extraction of clean water The purified wastewater will be extracted from the clear water zone by means of a pneumatic lift and will be directed into a body of water, leached to groundwater or reutilized.

9 How does Batchpur work? 5. Extraction of surplus sludge The excess biomass resultant from the purification process will be directed to the mechanical pretreatment chamber by means of a pneumatic lift. The procedure starts over again.

10 Control by air

11 Depending on the demand

12 O2: From bubble to cell

13 Function pressure sensor

14 Evaluation by authorised 3rd Party

15 Applications Single houses Small groups of houses Small commercial premises Replacing existing septic tanks Quartier in emerging cities Villages, oases Abattoirs Rural industrial buildings and offices Sport complexes Restaurants and public houses Smaller hotles Garden centers Camping sites Nursing homes Farms Stables/kennels large country estates and ranches...

16 Comissioning 10:30 a.m. Building pit is excavated, cleanness layer filled up: The plant has arrived! 10:45 a.m. The plant is lifted from the truck directly into the building pit.

17 Comissioning 11:00 a.m. The container is straightened before final lowering. The connection work can start. 12:00 a.m. The plant is running; the building pit is filled. The control unit can also be installed in the open in the GFK cabinet with comfortable access.

18 Possible extensions Solar Panels Residual sludge treatment Ultraviolet disinfection Automatic Oxygen Control Phosphate Elimination

19 Benefits Minimal maintenance, low operating costs Environmentally friendly Minimal visual impact (buried entirely underground) No smells (odor-free) Long emptying cycle of sludge (period o up to one year) Deals effectively with variable flows and loads Reliable operation and stand-by facility Safe, clean and accessible air diffuser system Small installation footprint and low installation costs Cost of sewers and pumping to closest municipality High-quality materials No pumps in the waste water (no blocking and wear of pumps in the small sewage treatment plant) Automatic adjustment of the compressor operating times to the actual plant load (patented) Available in different classes (C, N, D, H and P) Sole plant with patented oxygen control O2 control Patented filling level control Automatic recording of the waste water quantity to be treated (patented) Explosion proof (no electrical elements (pumps) are installed in the sewage treatment container) Compressed air lift pump of industrial standard (No pushed-in HT-tubes) Low-noise energy-saving step motors which show virtually no wear and tear Illuminated six-lines display Electronic operation diary USB interface Modem interface Easily upgradable Autonomy (Keeping the water) Water-proof air lift pumps
