new products & services 152 APRIL 2012 water water business CST WASTEWATER SETS NEW BENCHMARK WITH SMITH & LOVELESS' 95% GRIT REMOVAL DOWN TO 150 MICRONS Advanced inlet screening and grit removal technologies that set new performance benchmarks for municipal and industrial wastewater treatment plants are being introduced to Australasia by CST Wastewater Solutions. The technologies, which will be on display at Ozwater'12, include the latest Smith & Loveless PISTA® 360TM wastewater grit removal chamber, which extracts an unprecedented 95% of grit as small as 100 microns. "The established standard for grit removal has been 95% removal at 250 microns, so achieving the same removal efficiency at 150 microns (140 mesh) sets an entirely new benchmark," says Michael Bambridge, Managing Director of CST Wastewater Solutions. In addition to the PISTA chamber, which uses a patented V-Force BaffleTM to increase the effectiveness of the grit removal, CST Wastewater Solutions' latest technologies include high- performance inlet screening, new vertical screens, lateral membrane pre-screens and clarifiers. All the technologies are engineered to reduce investment, operational and maintenance costs, says Mr Bambridge, whose company's globally renowned technologies provide new and retrofitted solutions for municipal and industrial applications, backed by over 25 years of hands-on experience. Also on show will be water and wastewater technologies including Dissolved Air Flotation (DAF); clarifiers, tube settlers and thickeners; shaftless conveyors; sludge dewatering; septic receival stations; continuous sand filters; UV disinfection; anaerobic pre-treatment and biogas reuse systems; and packaged sewage systems. "The versatility and efficiency of our clarifier product has been demonstrated in a number of applications undertaken recently in partnership with Smith & Loveless, including an installation on a remote island, where two 11m-diameter clarifier mechanisms were provided for the upgrade of a sewage plant. Due to its remote location, the clarifiers were supplied in kitset form, including the steel tank, to minimise on-site work and optimise installation. The grit removal and pre-treatment technologies displayed by CST Wastewater Solutions at Ozwater are complemented by the latest pre-engineered Smith & Loveless TITAN MBR (membrane bioreactor) wastewater system for municipal and industrial applications. The innovative TITAN MBR system marries the wastewater treatment engineering expertise of Smith & Loveless with existing submerged membrane technology, says Mr Bambridge. The combination yields a dynamic membrane biological reactor (MBR), a system that provides end-users with high- quality treatment performance, minimal operational requirements, and a robust design that will stand the test of time. Plants come in standard and custom designs, and result in smaller footprints than conventional systems. Integral zones can be added to meet particular effluent goals, including nutrient removal, disinfection and post-aeration. Smith & Loveless supplier CST Wastewater Solutions is an Australian company formed more than 20 years ago by Michael Bambridge to introduce specialised wastewater screens to the industrial and municipal wastewater markets. CST has sold many screens in Australia and internationally, particularly into Asia and China. Over the past 10 years, CST has broadened its ability to service its markets by being able to supply a range of specialised wastewater treatment equipment that is competitively priced and of high quality. CST has an international network of representatives, with sales to Europe, Asia, China, Africa, South America and the US. Among CST's capabilities are water and wastewater screening; inlet screening, grit removal and dewatering systems; septic receival stations; dissolved air flotation; sedimentation and clarifier systems; shaftless conveyors; sludge dewatering; lime handling; continuous sand filters; microfilters; UV disinfection; anaerobic treatment and biogas reuse; and packaged wastewater treatment systems.

Completed in 2010, the 'Pimpama Waterfuture Master Plan Initiative' delivered multiple water sources to over 7,000 hectares of new homes located in Pimpama, 50 kilometres south of Brisbane. Installed by micro-tunneling company Rob Carr Pty Ltd, the project entailed construction of deep shafts (using concrete caissons) and manholes, as well as installation of the DN1400 gravity sewer at grades as low as 0.1%. In an Australian first, 820 metres of DN1400 HOBAS jacking pipe was micro-tunnelled in medium to extremely hard rocky terrain, under areas of environmental sensitivity. The HOBAS jacking pipe was successfully installed in multiple drives of almost 300 metres with loads of under 250 tonnes, crossing under dense bushland and regions of environmental sensitivity to build a gravity sewer as part of the $190 million works. HOBAS Jacking Pipe was the obvious first choice due to its low-risk properties. The ground conditions of hard, broken rock had proven to be very problematic for a nearby project that was jacking clay pipes. HOBAS was chosen because of its performance and successful jacking track record in similar varying and challenging ground conditions. The decision to choose HOBAS was also made easy thanks to its superior trenchless installation abilities and low impact on the environment. Due to the environmental sensitivity of the creek and surrounding flora and fauna, installing contractor, Rob Carr was keen to minimise the carbon footprint of the project. The project has delivered a new and improved wastewater management system that will stand the test of time thanks to the 100+ asset life of HOBAS jacking pipe.
