Återvunnet vatten: använda renat avloppsvatten i processen

Recycled water : use purified wastewater in the process (English)
Abstract [sv]

Fältstudien gjordes för att utreda om det var möjligt att använda renat, filtrerat avloppsvatten för polymerberedning och i längden även som övrigt processvatten på Ellinge reningsverk. Testerna utfördes i fullskala med både vatten från mellansedimenteringen och slutsedimenteringen. Genom omfattande provtagningar och analysering av resultaten visade det sig vara en fungerande metod utan negativ påverkan på polymerlösningen och slamavvattningen. Det krävs dock mer arbete och ytterligare reningssteg såsom desinficering för att implementera det renade avloppsvattnet på hela vattensystemet.  

Abstract [en]

The field study was done to investigate whether it was possible to use purified, filtered wastewater for polymer preparation and in the long run also as other process water at Ellinge treatment plant. The tests was performed in full scale with both water from the intermediate sedimentation and the final sedimentation. Through extensive sampling and analysis of results, it proved to be a working method without a negative impact on the polymer solution and sludge dewatering. However, more work and addiotional purification steps such as disinfection are required to implement the treated wastewater on the entire water system
