Sewer & Waste Water Infrastructure Corrosion Prevention<\/h2>\n

The root cause of odours and corrosion in sewer collection systems is sulphide generation by bacteria in waste water passing through sewer pipes and infrastructure. The gas released by this bacteria \u2013 hydgrogen sulphide (\u201crotten egg gas\u201d \u2013 H2<\/sub>S) is the primary cause of odours in sewer infrastructure. Another type of aerobic bacteria then utilises the H2<\/sub>S gas in the head space of the sewer infrastructure to produce sulphuric acid (H2<\/sub>So4<\/sub>) which corrodes concrete causing damage wastewater pipes and facilities. In severe situations, sewer pipe and manhole failures and collapses can result in disruption of services and uncontrolled releases of waste water into the environment. \u00a0Damage such as this can result in repair costs in the millions of dollars.<\/p>\n

Rather than allowing the build-up of H2<\/sub>S gas in the sewer infrastructure, an OdaTech force-ventilated odour control system continuously extracts air from the head space, preventing corrosion while also eliminating\u00a0complaints from nearby residents.<\/p>\n
