Treating sewage water from carwashes using a filter of peat and carbon-containing ash : an evaluation of efficiency and waste handling from an environmental perspective (English)
Abstract [sv]

Filtermaterial av 75 % torv och 25 % kolaska har använts under 2 respektive 4 år för rening av avloppsvatten från två biltvättar. Jämförelse med Kristianstads kommuns riktvärden för avloppsvatten från fordonstvättar visar att filtren fungerat. För avfallsklassning krävs kunskap om innehåll av miljöfarliga ämnen i produkter som använts i tvätthallarna. I brist på kunskap om innehåll av ej analyserade miljöfarliga ämnen i filtren anses förbränning vara ett bra omhändertagande ur miljösynpunkt, då energi och aska återvinns.

Abstract [en]

Sewage water from two car washes has been treated during 2 and 4 years respectively, using a filter made of 75 % peat and 25 % carbon-containing ash. A comparison with the guiding values for car wash sewage water in Kristianstad municipality shows that this type of filter works well. Classification of the filter as waste requires knowledge about the content of environmentally harmful substances in products used in the car washes. Because of the lack of knowledge about the content of non-analyzed substances in the filters, combustion must be regarded as an environmentally good way of disposing the filter material, as both energy and ashes are recycled.
