2. Trend in Danmark Centralized waste water treatment
Pumping water long distance
Transport system with a payback time at 75 years
Bound for investment for 75 years -> How is the situation in Denmark in 2090?
Example where they want to centralize a city with 240 PE 15,6 kilometers away. It require a new transport system and a large investment.
Decentralized waste water treatment
Require a robust treatment plant
Outlet at least as clean as central waste water treatment plant
Low need for man power

3. Why Grundfos BioBooster ?
Growing population and increasing stress on natural resources
Increasing demand for environmental protection & sustainable use/re-use of water
Growing need for decentralized solutions
Robustness/ease of operation, better treatment performance and competitive life cycle cost will be required

4. Focus segments Municipal segment Hospital segment Industrial segment
Complete municipal plants for 1000 – PE greenfield and upgrade projects
Complete plants for resorts, hotels, golf courses etc m3/day.
Hospital segment
Complete plants for removing pharmaceuticals for hospitals with 300 – 2000 beds
Industrial segment
Plants to F&B IKA’s (Arla, CocaCola, Pepsico, Nestle, Unilever, Carsberg etc.) from 100 – 2000 m3/day.

5. Grundfos Wastewater treatment plant concept
2. Process tanks
Skids for integration into
existing building/basement
in a new building
a climate shield
4. Optional
Ozone + GAC post treatment for hospitals
5. Optional
Sludge drying to
90% dry matter for larger plants
3. Ceramic membrane filtration
Good service access for
operation and maintenance
chemcial exchange
by-product removal
6. Optional
air treatment/closed tanks for odour/patogen removal in residential areas
1. Mechanical pre-treatment

6. Grundfos Membrane Filtration Unit (MFU)
Ceramic membrane discs with an effective membrane area of 34 m2 per MFU.
Ultrafiltration 200 nm pore size for bacteria free effluent
Safe and reliable fouling elimination based on unique rotating filter discs
Enables MLSS: 3-30 g/m3 operating interval.
Enables more biological processes in one tank (aerobic, anaerobic, anoxic) (as no air used)
Each filter unit has a peak capacity of 65 m3/day and annual average of 32 m3/day.
No need for membrane replacement - discs can be reburned.
Permeate
0-2 bar TMP control
Process tank
3 – 30 kg MLSS/m3
Sludge 4-6% DM
2-4 x Recirculationsflow

7. MFU performance Peak flux test (6 weeks from Monday to Friday)
Flux 40 during weekends and receiving 1 x CEB
86 lmh has been demonstrated on 6°C cold wastewater in Norway.

8. Grundfos MFU skid 8 Membrane Filtration Units per 1 MFU skid
Dimensions 1,1 m x 11,5 m x 2,5 m skid
Key features of GRUNDFOS MFU skid
Peak capacity up to 518 m3/day over 5 days per MFU skid
Automatic fine-grained flow capacity adjustment for optimum energy consumption by using MFU idling function.
Integrated sludge de-watering functionality up to 4-6% dry matter
Online leakage control and auto shut-off of each single MFU
Fully automated operation of MFU skid incl. recovery cleanings
Competitive life cycle cost when compared with other membrane systems for 1000 – PE plants

9. ODIN optimizer Operator inDependent intellIgent operatioN Example from testplant
Rapid flux drop – ODIN automatically reacts by:
Increasing the TMP
Shortening the cycle (17 min  8 min)
Increasing RPM (100 RPM  130 RPM)
ODIN Sludge Quality module registered the change in sludge properties!
Recovery:
- Cycles get longer
- TMP stabilizes
- RPM drops

10. MFU energy optimization by ODIN
Manual trim of parameters
(TMP, RPM, backwash interval, time and pressure)
Automatic adjustment of all parameters using ODIN algorithm

11. Automatic fouling estimation/CEB
Case Hemsedal

12. Grundfos BioBooster WWTP concept
Key features
Industrialized and modular built-up concept provides a high quality product with a short project execution time and limited onsite works.
Skids allows for integration into
building, or
climate shield directly on skids
Robust design and highly automated operation ensures low operator and service requirements
Concept suits Design, Build and Turnkey type of contracting and brings low risc and savings to the employer.

13. More on why BioBooster
Consider a decentralized Grundfos BioBooster MBR systems:
Environmental drivers
to maintain an aquatic life in smaller local water streams
to ensure compliance with stricter effluent requirements – (P <1 and N <8 mg/litre)
to protect receiving waters for recreational purposes (bathing and fishing eg.) against bacteria
when the effluent is reclaimed for re-use in golf courses, agriculture and the like.
to prevent antibiotic resistant bacteria and micropollutants from entering the environment and to make the plant future-proof.
Technical drivers
when loadings are seasonal fluctuating, eg. due to tourism
when cold weather conditions are normally too cold for nitrification
when the plant needs to be prepared for future increased load rates.
when operations needs to be highly automated and require minimum staff attention
when space is limited or the the plant is close to odour sensitive neighbours
