Innovation Showcase 4. CALCLEAR Power & Water: CALCLEAR Water Conditioner
We loved it! It was fantastic to hear about all the different technologies
8. Evoqua Water Technologies: MEMCOR CP II Ultrafiltration System
The patent-pending CALCLEAR Water Conditioner is a pre-treatment for water Evoqua’s MEMCOR® CP II Ultrafiltration processing to prevent and remove adhesive System offers compact and modular scale. This means water systems no longer ultrafiltration for industrial and municipal require chemical dosing and chemical water treatment. The modular, compact Sue Keay, cleaning to maintain and achieve lower UF system minimises footprint, reduces Australian Water Recycling Opex costs in terms of energy, labour, time installation costs and simplifies system Centre of Excellence and chemical descalant. This technology is operations, reduces customer costs with coupled with their EMF water-conditioning a larger surface area module and shorter control system used to generate a drive signal of various resonance duration backwash, and offers easy maintenance access compared frequencies through coils wrapped around pipes carrying the water to previous MEMCOR systems. The system is suitable for new or flow. CALCLEAR Power and Water provides a simple pre-treatment major plant upgrades. for membrane water, filtration and water recycling systems, including 9. Green Wastewater Group: Integrated brackish desalination, wastewater treatment, as well as potable water treatment and industrial water treatment. Transpiration Technology
5. Clean TeQ: Continuous Ionic Filtration (CIF) Clean TeQ developed its Clean-iX™ continuous counter-current ion exchange platform for separation and purification, metals recovery and water treatment. The platform technology has been used to develop their Continuous Ionic Filtration (CIF) process. CIF™ ion exchange platform involves dealkalisation, target ion removal and pre-treatment to membranes, allowing specific targeted ionic species removal. This can include removing scaling ions, fouling species and heavy metals. It can be used in highly alkaline waters to treat and deliver water for beneficial re-use (for example, areas of CSG fields where groundwater requires dealkalisation for agricultural use or in areas where high scaling waters are found prior to RO). TDS differential of approximately 2000mg/l can be achieved using this innovative ion exchange technology.
6. CSIRO Water for a Healthy Country Flagship: Sewer Sentinel CSIRO’s ‘Sewer Sentinel’ manifold technology utilises carefully designed fluid dynamics to create high turbulence and velocity in the sample stream which, when directed toward a sensor, effectively scours the sensor surface, preventing build-up of contamination and maintaining data integrity for long periods without technician intervention. The technology provides continuous real-time monitoring and can be used as an early warning and/or process control system whereby toxic flows can be diverted, significantly reducing WTP process costs, minimising downtime, improving output quality and avoiding penalties for out-of-spec discharges.
7. Diagnostic Technology: Phytoxigene Phytoxigene is a molecular (DNA) based technology that detects and quantifies the presence of Cyanobacteria, blue-green algae and their toxin-producing genes in aquatic environments. Not all Cyanobacteria species produce toxins, therefore the presence of an algal bloom does not immediately defer a risk of toxins being present. Additionally the mass of algae does not necessarily correlate to the amount or potential of a toxin event. The Phytoxigene test quantitates both the amount of overall Cyanobacteria present in a water sample, along with the number of genes that are responsible for the production of the toxins. Toxins associated with blue-green algae are split between hepatatoxins (which cause damage to the liver) and neurotoxins (which cause neurological damage). Hepatatoxins include microcystin, nodularin and cylindrospermopsin, while saxitoxin is the primary neurotoxin produced by Cyanobacteria. Both toxins have significant health impacts on humans and other animals. The test is completing its final validation process, with trials underway in the US and Australia.
Green Wastewater Group designs and constructs on-site decentralised wastewater solutions for residential and commercial facilities utilising evapotranspiration and filtration provided by plants. It is a cost-effective wastewater treatment solution with a sustainable carbon footprint. The company’s Integrated Transpiration technology is unique globally in that it utilises broadleafed terrestrial plants in a closed environment to filter and dispose of wastewater on a commercial scale, disposes of a substantial proportion (up to 100 per cent of wastewater in processing), requires a lower total treatment and irrigation area, has low operating and maintenance cost, low risk of failure, and even contributes to the aesthetics of a residential site rather than detracting from it.
10. Helio Pur Technologies: Bio-Solar Purification (BSP) Bio-Solar Purification is a new technology able to remove hazardous compounds and microbial contaminants, paving the way to cost-effective and sustainable water reuse and recycling. Without evaporation, BSP technology combines sunlight effects with microalgae growth and photosynthetic oxygen production to purify wastewaters. These processes intensify ecosystems services occurring at the air-water interface in closed tubular systems. Previous testings on a pilot scale have proved efficiency of the technology to remove inorganic nutrients, dissolved metals, xenobiotics and hazardous microbial contaminants such as coliforms. The main advantages are that CO2 is the only reagent that arises from closed aerobic pre-treatment, and as the system captures CO2 in operation it is carbon negative. First application is domestic wastewater reuse for agricultural irrigation, including microalgae as organic amendment and subsequent aquifer replenishment with nutrient-free freshwaters. Purified groundwater can then be recycled for domestic uses.
11. iota Services: Talking Tanks Talking Tanks monitors water levels in a rainwater tank and automatically releases water at a controlled rate if required. The system pre-empts the release of water from set points that are chosen by the user, according to rain or storm predictions received via a communications link to the Bureau of Meteorology. The automatic release creates storage capacity and prevents overflows of stormwater. The technology has strong potential application for water utilities, local governments, water traders and irrigators. iota forms the commercial arm of South East Water, one of the leading water retailers in Victoria, which promotes innovative ideas and proven technologies for use across a range of sectors.
