WATER BUSINESS WATER JUNE 2013 108 Water Business SERVICE THAT'S NOT TO BE SNIFFED AT Odours from wastewater treatment plants (WWTPs) and collection systems can be more than just a nuisance. They can be an indicator of corroding assets and potential health and safety issues. CH2M HILL's specialists tailor odour control systems to the processes and types of odours they are designed to treat. Cost-effective and long-lasting, they are simple to operate and maintain. CH2M HILL offers a full suite of odour services, from investigations through to design, construction, commissioning, testing, performance monitoring and refurbishment, taking on single project stages or an entire project from start to nish. This reduces duplication, improves ef ciency and gives the assurance that comes with the shared objective of an effective odour solution. Technical Services include: • Application of odour control technologies including biotechnology, chemical scrubbing, chemical dosing, activated carbon and thermal oxidation; • Odour emission sampling and characterisation; • Development of odour control alternatives; • Odour compliance strategy development (including air dispersion modelling) and implementation plans; • Septicity, corrosion and ventilation modelling of sewers; • Public outreach strategies and tools to address odours and licensing issues, including regulatory review and compliance determination; • Design and construction of new odour control systems or auditing of existing systems; • Construction supervision and contract administration for odour control packages with technical backup; • Testing, commissioning and performance evaluation; • Liaison with regulatory agencies; • Studies for new and existing collection systems, pump stations, rising mains and gravity sewers; • Training and advisory services. CH2M HILL has also taken part in several major odour research projects. These include: • ARC Sewer Corrosion and Odour Research (SCORe) Linkage Project; • WERF Minimisation of Odours and Corrosion in Collection Systems; • WERF Biosolids Odours Research Phases 1 to 3. The CH2M HILL team has undertaken hundreds of investigations ranging from small project audits to delivery of some of the biggest odour projects in the country, including: • Chemical scrubbers treating 680,000m3/hr, Malabar WWTP (New South Wales); • Bio lters treating 240,000m3/hr, Eastern Treatment Plant (Victoria); • Biotrickling lters treating 126,000m3/ hr, Western Treatment Plant (Victoria); • Biological gas scrubbing system treating over 20,000ppm H2S at the Gippsland Water Factory (Victoria); • Developed corrosion and odour solutions for collection systems ranging from less than 0.5 MLD to over 400 MLD. CH2M HILL focuses on delivering innovative, sustainable, cost-effective solutions. Examples of this approach are: • New membrane PST odour covers, Cronulla WWTP: Maintaining accessibility while minimising air treatment load; • Targeted odour control, Farley WWTP: Determined if resources would be optimally deployed at the plant or in the sewer network to minimise plant odour; • Brightwater WWTP (USA): Achieved zero odour impact at the boundary of the 136 MLD treatment plant; ontact AWMA to discuss how quality water ontrol infrastructure can reduce your capital xpenditure and improve operations. 100% Australian Owned & Operated Leaders in Water Control Solutions w w w.awma.au.com Ph 1800 664 852 DESIGN - MANUFACTURE - INSTALL Custom designed high head penstock Biotrickling lter system under construction at Cronulla WWTP.
