2Trend in Danmark Centralized waste water treatment Pumping water long distanceTransport system with a payback time at 75 yearsBound 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 treatmentRequire a robust treatment plantOutlet at least as clean as central waste water treatment plantLow need for man power
3Why Grundfos BioBooster ? Growing population and increasing stress on natural resourcesIncreasing demand for environmental protection & sustainable use/re-use of waterGrowing need for decentralized solutionsRobustness/ease of operation, better treatment performance and competitive life cycle cost will be required
4Focus segments Municipal segment Hospital segment Industrial segment Complete municipal plants for 1000 – PE greenfield and upgrade projectsComplete plants for resorts, hotels, golf courses etc m3/day.Hospital segmentComplete plants for removing pharmaceuticals for hospitals with 300 – 2000 bedsIndustrial segmentPlants to F&B IKA’s (Arla, CocaCola, Pepsico, Nestle, Unilever, Carsberg etc.) from 100 – 2000 m3/day.
5Grundfos Wastewater treatment plant concept 2. Process tanksSkids for integration intoexisting building/basementin a new buildinga climate shield4. OptionalOzone + GAC post treatment for hospitals5. OptionalSludge drying to90% dry matter for larger plants3. Ceramic membrane filtrationGood service access foroperation and maintenancechemcial exchangeby-product removal6. Optionalair treatment/closed tanks for odour/patogen removal in residential areas1. Mechanical pre-treatment
6Grundfos 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 effluentSafe and reliable fouling elimination based on unique rotating filter discsEnables 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.Permeate0-2 bar TMP controlProcess tank3 – 30 kg MLSS/m3Sludge 4-6% DM2-4 x Recirculationsflow
7MFU performance Peak flux test (6 weeks from Monday to Friday) Flux 40 during weekends and receiving 1 x CEB86 lmh has been demonstrated on 6°C cold wastewater in Norway.
8Grundfos MFU skid 8 Membrane Filtration Units per 1 MFU skid Dimensions 1,1 m x 11,5 m x 2,5 m skidKey features of GRUNDFOS MFU skidPeak capacity up to 518 m3/day over 5 days per MFU skidAutomatic fine-grained flow capacity adjustment for optimum energy consumption by using MFU idling function.Integrated sludge de-watering functionality up to 4-6% dry matterOnline leakage control and auto shut-off of each single MFUFully automated operation of MFU skid incl. recovery cleaningsCompetitive life cycle cost when compared with other membrane systems for 1000 – PE plants
9ODIN optimizer Operator inDependent intellIgent operatioN Example from testplant Rapid flux drop – ODIN automatically reacts by:Increasing the TMPShortening 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
10MFU energy optimization by ODIN Manual trim of parameters(TMP, RPM, backwash interval, time and pressure)Automatic adjustment of all parameters using ODIN algorithm
12Grundfos BioBooster WWTP concept Key featuresIndustrialized and modular built-up concept provides a high quality product with a short project execution time and limited onsite works.Skids allows for integration intobuilding, orclimate shield directly on skidsRobust design and highly automated operation ensures low operator and service requirementsConcept suits Design, Build and Turnkey type of contracting and brings low risc and savings to the employer.
13More on why BioBoosterConsider a decentralized Grundfos BioBooster MBR systems:Environmental driversto maintain an aquatic life in smaller local water streamsto 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 bacteriawhen 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 driverswhen loadings are seasonal fluctuating, eg. due to tourismwhen cold weather conditions are normally too cold for nitrificationwhen the plant needs to be prepared for future increased load rates.when operations needs to be highly automated and require minimum staff attentionwhen space is limited or the the plant is close to odour sensitive neighbours
