Odour remediation with chlorine dioxide

Written by Henrik Møller Jørgensen, Technical Manager at PROTOX Chlorine dioxide is well suited for odour remediation, and effectively removes odour nuisances that arise, among other things, after:

• Mould growth and damp damage
• Rising sewage
• Organic pollution
• Advice and degradation of materials
• Animal husbandry or animal material
• Stagnant water or biofilm in installations
• Fire-, smoke- or waste-related impacts

During odour remediation, it is crucial to first locate and remove the odour source itself. If the contaminated material is left behind, the odour may return. Chlorine dioxide should therefore be used as part of a comprehensive remediation process that includes cleaning, drying, ventilation and, where necessary, material removal. Chlorine dioxide works by oxidation Klordioxid kan anvendes som et effektivt led i professionel lugtsanering, hvor almindelig rengøring, udluftning eller parfumerende produkter ikke er tilstrækkelige. Mange lugtgener skyldes kemiske forbindelser, der sætter sig i overflader, materialer, sprækker, hulrum og installationer. Det kan f.eks. være lugt efter brand og røg, affald, kloakpåvirkning, skimmel, fugtskader eller urin fra dyrehold. I modsætning til produkter, der blot dækker lugten midlertidigt, virker klordioxid ved oxidation. Det betyder, at stoffet reagerer med de lugtbærende forbindelser og nedbryder dem kemisk. Derved behandles selve årsagen til lugten i stedet for kun symptomet. Det gør klordioxid særligt relevant ved vedvarende lugtgener, hvor lugten har trængt ind i materialer eller spredt sig til svært tilgængelige områder. Odour remediation after fire and smoke damage In the event of fire and smoke damage, odours can be difficult to remove because smoke particles and soot can penetrate porous materials, textiles, woodwork, insulation, concrete, fixtures and ventilation systems. Even after thorough cleaning, a persistent smell of smoke may remain, which is released over time. Here, chlorine dioxide can be used as part of the final odour remediation, once loose soot, contaminated material and visible residues have first been removed. The treatment can help to reduce the remaining odour-bearing compounds that ordinary cleaning does not always reach. Odour remediation following pets and mould Chlorine dioxide is also well suited for odours from waste, organic decomposition and sewage impacts. Such odours can be strong and persistent because they often originate from organic compounds, sulphur compounds, amines and other chemical substances with a very low odour threshold. Even small amounts of residual contamination can therefore cause significant odour nuisances. Once the primary contamination has been removed, chlorine dioxide can help to break down the remaining odorous substances and improve the overall experience of the room or installation. In animal husbandry can urine, faeces and organic matter cause odour nuisances that embed themselves deeply in floors, walls, grout, woodwork and porous surfaces. Urine odour can be particularly difficult to remove because the odour does not just lie on the surface, but often penetrates into the material and develops over time. In connection with remediation following animal keeping, the area should first be thoroughly cleaned, and heavily contaminated materials should be assessed with a view to replacement. Chlorine dioxide can then be used to reduce the remaining odour load and treat the areas where the odour might otherwise be difficult to eradicate. In the event of mould and damp damage The odour is often one of the most troublesome problems. The characteristic musty smell can linger even after the visible mould has been removed. This is because odour-carrying compounds may have become embedded in building materials, cavities and dust. Chlorine dioxide can be used here as a supplementary step in the remediation process, where the aim is not only to reduce mould-related contamination, but also, to a large extent, to eliminate the persistent odours of damp, mustiness, mould and stuffiness. Prevent the bad smell from returning En af fordelene ved klordioxid er, at det kan anvendes både på overflader og i rumbehandling, afhængigt af opgavens karakter. Som gas eller vandig opløsning kan stoffet komme i kontakt med områder, der kan være vanskelige at behandle med traditionelle metoder. Det gælder f.eks. sprækker, hulrum, rørføringer, afløb, tekniske installationer og andre steder, hvor lugt kan samle sig og frigives over længere tid. En effektiv lugtsanering kræver dog altid, at lugtkilden først identificeres og håndteres. Hvis affald, sod, fugt, urinmættede materialer eller anden forurening bliver liggende, kan lugten vende tilbage. Klordioxid bør derfor betragtes som en del af en samlet saneringsproces, hvor rengøring, fjernelse af forurenet materiale, udtørring, ventilation og eventuel materialekontrol indgår. Når forarbejdet er udført korrekt, kan klordioxid være et effektivt afsluttende behandlingstrin, der reducerer restlugt og forbedrer indeklimaet. Behandling med klordioxid skal udføres kontrolleret og efter produktets anvisninger. Under behandlingen bør området normalt være ubeboet, og mennesker, dyr og planter bør ikke opholde sig i lokalet. Efter behandlingen skal der sikres tilstrækkelig ventilation og afgasning, før området tages i brug igen. Korrekt anvendt kan klordioxid være et professionelt og effektivt værktøj til lugtsanering efter blandt andet brand, røg, affald, kloakpåvirkning, skimmel, fugtskader, dødedyr, lig og urin fra dyrehold. Stoffet er særligt relevant, når lugten er trængt ind i materialer eller findes i områder, hvor almindelig rengøring ikke kan løse problemet alene. Find Protox products for odour remediation
