1 Cleaner water – Greener environment
GRUNDFOS BIOBOOSTER GBB YWPDK | March 2015 | Anne Barslund Click to edit Master text styles

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
