When used together with PIHA’s grooved-end HDPE Tight Fit lined steel pipe, the complete system provides a fast, easy bolted connection and requires minimal fabrication. It combines the advantages of fast installation, design integrity and reliable operation. The pipes are prefabricated at PIHA’s warehouse in Perth and shipped together with couplings, or can also be grooved and lined on-site, depending on the project size and requirements.

Johannesburg-based WEC Projects won the tender issued by East Rand Water Care Association (ERWAT) aimed at improving the capacity of the Hartebeestfontein WWTW by 5ML/day. Nereda is a new aerobic granular sludge technology that purifies wastewater by controlling the growth and formation of microorganisms. The technology was invented by the Delft University of Technology in the Netherlands and developed in a unique public-private partnership between the University, the Dutch Foundation for Applied Water Research (STOWA), the Dutch Water Boards and Royal HaskoningDHV. Worldwide, there are dozens of plants in operation and under construction, including in Brazil, Australia and in South Africa’s Gansbaai and Wemmershoek. Graham Hartlett, Sales and Marketing Manager of WEC Projects said: “When this project came out on tender, we immediately recognised that it would be an excellent match for the Nereda technology. The advantages of being able to use the existing infrastructure added much value to the client. Nereda technology can be deployed on a smaller footprint. Capital and operational costs are also big factors to consider.” According to the Nereda Global Director, Rene Noppeney: “The technology represents the next level in the evolution of water treatment technology. Aerobic granule treatment is the next technology and is here to stay. The great benefit of Nereda is that it is proven in practice, also in South Africa. It requires less spaces and resources, uses much less energy and involves no chemicals. The first implementation of Nereda in Gauteng is the perfect opportunity to showcase this award-winning technology and WEC Projects is excited at the prospect.” HACH LAUNCHES 5500SC AMMONIA MONOCHLORAMINE ANALYSER Hach is introducing an important and innovative new technology for the water industry, the 5500sc Ammonia Monochloramine Analyser. The 5500sc Ammonia Monochloramine Analyser offers a reliable, easy-to-operate and low-maintenance solution to allow chloraminating water treatment facilities to continuously monitor their chlorine to ammonia ratio on-line and assure there is no free ammonia in the system that could lead to nitrification. Continuous on-line monitoring with the 5500sc Ammonia Monochloramine Analyser provides a more accurate and complete picture of the chloramination process, giving operators all the information they need to eliminate nitrification events and taste and odour issues. The analyser is easy to use, featuring a user-friendly interface, simple troubleshooting menu and color-coded reagent bottles. “Hach has been a front runner in this space for 15 years and we’ve learned a lot from our customers. We’ve taken our proven, existing measurement methodology and improved every aspect of the user experience,” says Jeff Stock, Global Product Manager for Disinfection at Hach Company. At-a-glance status lights are a convenient indicator that the instrument is up and running. PROGNOSYS, the analyser’s onboard predictive diagnostic software, provides early insight into the measurement reliability and service requirements of the instrument. The dual colorimeter design leads to faster results, while the state-of- the-art pressurised reagent delivery system eliminates the hassles associated with standard pumps. With the 5500sc Ammonia Monochloramine Analyser, it has never been easier to monitor your chloramination process online.
