AQUA Industrial Watertreatment MEMBER OF THE MPS GROUP Maarten ter Woerds 1 AQUA as part of the MPS Group Former : 2 Our Sales Offices UK/Ireland HQ = The Netherlands Denmark Sweden Germany Poland Russia USA/Canada China Mexico Indonesia Brasil KSA Chili Spain France 3 AQUA Industrial Watertreatment Specialised waste water treatment solutions for the food industry • Red meat (cattle – sheep – goat etc), white meat (chicken– duck – Geese - Turkey etc), dairy, fish and beverage industry Water re-use • From waste water up to potable water quality Scope of supply • From retrofit to complete solutions • Covering the complete technological area (aerobic / anaerobic) Primary Treatment Secondary treatment Tertiary treatment VoltaMix CSTR 4 Some of our references worldwide 5 Industrial wastewater The goal of wastewater treatment Meet effluent discharge parameters of authorities Reduce operational and discharge costs Water re-use in case of unavailability Recovery of valuable by-products Promote environmental friendly operation 6 Industrial wastewater Examples of pollution 7 Industrial wastewater Where does wastewater comes from Wastewater comes from many different places like: Production processes Cleaning Sanitary water Rainwater 8 Odor in wastewater treatment systems Statement 1 : Odor will not occur when the system is designed well Statement 2: Odor will not occur when the management of treatment system is well organized Statement 3: In some cases extra technology must been foreseen to treat odor 9 Project example – WWTP lay-out Tertiary treatment Biological treatment Pre-treatment 10 Industrial Water Treatment in 4 steps and the risks of odor 1. Removal of course particles by means of mechanical separation Screen & Filters 2. Removal of suspended solids by means of flotation (dissolved air flotation) without chemicals DaFinci® 3. Removal of the dissolved pollution fraction by means of aerobic biological treatment system BioFlot® 4. Removal of the remaining pollution by means of effluent polishing CuriEau® 11 Pre-treatment: pump pit Collection of the water from slaughter area Starting point of the WWTP No buffer / no retention = design No floating layers = design So sediment = design Daily check = management 12 Pre-treatment: screening area Downstream protection of equipment Screened material discharge via vacuum system = design discharge via container/bin = design Empty as much as possible = management Sucking of the air from the container = technology 13 Pre-treatment: DAF area D I R T C L E A N SS, Suspended solids Floating solids • Free oil & fats Settleable solids • Sand 14 Pre-treatment: DAF area Influent + sludge and effluent are separated = design Sludge is collected in a small compartment = design The compartment must been emptied = management DAF can be covered = design Sludge can be discharged to rendering = management Sucking of the air from the top = technology 15 Biological treatment 16 Biological treatment AQUA Anaerobic & Aerobic watertreatment– Sludge separation Sedimentation BioArt® BioClar® Flotation BioFlot® Filtration BioBrane® Sedimentation Flotation Filtration 17 Biological treatment System designed on daily pollution load = design Oxygen demands controlled by software = design Daily measurement on key parameters like MLSS and pollution load = management Daily finetuning of the settings = management Retrofit in case of increasing of volume and/or pollution = management 18 Tertiary treatment Media filtration Removal of last solids, precipitates, turbidity Water is almost free op pollution Chlorination Chemical disinfection Removal residual organic pollution & color Reliable method of disinfection 19 Tertiary treatment : effluent Water re-use possibilities with grey water Irrigation / Gardening / Street cleaning Truck washing Firefighting This is widely accepted in the market and industry. These types of water will not have an odor any more unless the 3 treatment stages are not well managed 20 Sludge treatment What is sludge? Sludge is concentrated pollution source of odor! Pre/bio treatment sludge: Stabilization (rendering etc) free of odor Biodigester free of odor Dewatering (volume reduction) eg Decanter centrifuge more concentrated 21 Examples of odor technology Biofilter Air washer Chemical scrubber Cover for odor control 22 General remarks for prevention Cover following areas as much as possible Pump pits Containers / bins Anaerobic reactors Buffers Discharge waste materials on frequent base Design the treatment building as a closed building keep possible odor inside and treat it at the source Management consists also cleaning the building good housekeeping 23 Conclusions There are 3 main factors to prevent odor around the WWTP Design of the WWTP Technology to treat odor Management (housekeeping) of the WWTP MANAGEMENT OF THE WWTP IS THE KEY FACTOR IN ODOR PREVENTION 24 Aqua Industrial Watertreatment Full line supplier 24/7 support Control/software fully in house Focus on operational cost reduction, odor control, safety, footprint Proven quality High track record Local presence with our partner AACE 25 Questions? 26 AQUA Industrial Watertreatment “complete solutions for wastewater- and sludge treatment in the food processing industries” 27 Thank you for your attention… AQUA Industrial Watertreatment B.V.
