Prior Information Notice For Water-Purifying Apparatus-Delivery And Installation Of A Water Treatment Installation Based On Membrane Filtration For Treatment Of Wwtp Effluent To Drink Water And For Artificial Supplement Of Groundwater In The Old Flushing Moat Of Water Extraction “De Westhoek” In De Panne. A New Water Treatment Installation Must Be Installed In The Existing Water Extraction Building. The Present Assignment Concerns The Delivery And Installation Of A Water Treatment Installation Based On Membrane Filtration For Treatment Of Wwtp Effluent To Drink Water And For The Artificial Supplement Of The Groundwater In The Oude Spoelgracht Of Waterwinning De Panne, At The Next Address: Kerkstraat 54, De Panne, Belgium. Aquaduin Is A Pioneer In The Field Of Water Reuse. In Wpc Torreele (Wulpen), Aquaduin Has Been Treating The Effluent From The Wwtp Wulpen To Infiltration Water Since 2002. The Most Important Steps Are Ultrafiltration And Reverse Osmosis. The Biofouling Prevention Is Based On The Dosage Of Sodium Hypochlorite For Forming Monochloramines; The Scaling Prevention On The Combination Of Ph Correction And Dosage Of Antiscalant. The Infiltration Water That Is Thus Produced Is Infiltrated 2.5 Km Further In The St.-André Dune Water Extraction. This Happens Partly In Open Ponds And Partly In Underground Infiltration Crats. The Whole Is Based On The Multiple-Barrier Principle. This Principle Will Now Also Be Applied In The Winning De Westhoek, On The Effluent Of Wwtp Adinkerke Managed By Aquafin. Here Too, The Multiple-Barrier Principle Will Be Applied. The First Step Uses Membrane Techniques (Uf/Nf And Ro). In A Second Step, The Purified Water Will Be Infiltrated In The Old Rinsing Moat Of The Duinwaterwinning De Westhoek. The Surplus Of Production After Reuse Will Be Supplemented Directly In The Reinwaterkelder And Mixed With Other And Harder Drinking Water, Which Will Make The Supplied Drinking Water In De Panne Less Hard. To Maintain The Multiple-Barrier Principle, The Latter Part Current Will Have To Be Treated Extra With Active Cabbage And With Dosage Of Sodium Hypochlorite.
