SEEPEX Smart Air Injection
The high viscosity and abrasiveness of the medium means that a significant pressure loss needs to be overcome in the conveying pipeline.
Conveying dewatered sludge over long distances represents a major challenge for municipal wastewater treatment facilities. The high viscosity and abrasiveness of the medium means that a significant pressure loss needs to be overcome in the conveying pipeline.
For Smart Air Injection (SAI), the developer, SEEPEX, has used a combination of pump conveying via a progressive cavity pump and dense phase pneumatic conveying.
“SAI forms plugs of dewatered sludge and ‘shoots’ them down the line by means of compressed air pulses.”, states Head of SEEPEX Product Management, Dr.-Ing. Stephan Mottyll.
The new process requires only a costeffective piping system made from plastic material, which plays a role not only when the system is bought new, but also whenever running expenses such as maintenance and operating costs need to be reduced.
Another attractive feature is the low operating costs, which result from low energy consumption, long pump maintenance cycles of around two years and cheaper spare parts compared to other pumping processes.
The time requirements for maintenance are minimal, at just a few hours, and can typically be performed by a single person without additional hoist/crane equipment due to the lower weight of components.
Thanks to the maintain in place pump design, the disassembly of the pipeline is not required.
The lower pressure level additionally ensures an increased service life for the components and a reduced pump footprint. Moreover, the automated system solution along with process monitoring, can be integrated into existing automation and control systems via conventional bus interfaces, says SEEPEX.
Klein Tools introduces the KTB1000 Portable Power Station, providing up to 1500 W of continuous power to corded electrical tools and electronics. Additionally, Klein introduces the new 60W Portable Solar Panel (sold separately), which can be paired with the Power Station to extend runtime in the field.
The KTB1000 is a gas generator without the gas that can power up to 11 devices simultaneously without the noise, maintenance, fluids or safety risk associated with traditional generators.
The unit's heavy-duty construction and washable filters have been developed with the job site in mind. The runtime can be extended by pairing the Power Station with up to two of Klein’s new solar panels to power a job site all day long.
Portable Power Station, 1500W (Cat. No. KTB1000)
• Delivers 1500 W of Pure-Sine Wave AC power

• Pass through charging to simultaneously charge KTB1000 and power devices
• Digital LCD screen displays real-time performance metrics including time until empty
• Job-site ready design includes heavy-duty construction and washable dust filter
• Extend runtime by pairing up to two Klein Tools Solar Panels
(Cat. No. 29250 – sold separately)
60W Portable Solar Panel
(Cat. No. 29250)
• Power of the sun to provide up to 60 W of charging.
In the transmission and distribution (T&D) grid business, “trust” might be the single most important commodity – trust that when a customer flips a switch or powers up a production line, the electricity will be there.
Trust that if something happens to the electricity supply, the grid operator will be able to provide a speedy response, and trust that operators will ensure grid reliability while at the same time helping to implement the energy transition.
As it turns out, T&D grid operators across the Middle East can help strengthen this customer trust by improving their own operations, in part through the power of data and digital technology.
DATA AND THE SINGLE SOURCE OF TRUTH
If grid operators can develop a complete, reliable, accurate digital view of their own networks, they can unlock the benefits that a digital transformation can offer, in terms of performance, reliability and cost reductions. In short, they need to develop a trusted source of record for their network assets and operations.
We all know that digitization is built upon reliable, high-quality data. In this region, and around the world, it is common for T&D grid operators to have lots of data and information about their networks, but not a consolidated, end-to-end clear and dependable view. That situation can result in diminished reliability, performance, and futurereadiness – not to mention missed opportunities.
Often, these operators are managing several disparate databases with incomplete and contradicting network models, created by different vendors cataloguing assets with an eye on different uses, including distribution, maintenance, outages, and customer troubleshooting. As a result, existing network models are sometimes inaccurate, conflicting, or are just too hard to make sense of.
NEW PRESSURES ON T&D NETWORKS This situation is untenable, given the current and future challenges facing T&D grid operators, including the need to ensure reliability, customer satisfaction, and cost containment in the face of the energy transition that will put significant pressure on T&D networks.
These pressures include everything from the rapid addition of renewables to the increasing electrification of everything; from the growing presence of mobile battery storage (and intermittent load) on the grid provided by electric vehicles to battery storage in homes and businesses.
Operators also must be ready to address the continued expansion of cities and the growth of industry and manufacturing in our region, as well as the direct impact of climate change, whether that be freak weather events or unprecedented peaks in energy demand.
TRUST THE NETWORK MODEL
Preparing for these challenges begins with the need to address the “trust” issue and get to the truth of each grid’s operations. That requires building a reliable, high-quality network model containing full information on assets, their geospatial location, how they are connected in the network, and the flow of electricity.
Building this trusted source of data is itself a journey. For example, in the area of design, this process means transitioning from paper maps and design sketches with multiple points of entry, to a midpoint that uses CAD-file-based digital maps and spreadsheets, that often still results in disparate copies for different views of the network.
The endpoint in design would be a single-entry network model with different visualizations for design workflows, approval and network construction, and commissioning needs.
Another example is in operations, where grid operators would move from duplicate modeling, redundant data entry reviews and approvals, and as-built lags of weeks or months. The midpoint would deliver data visibility and a shared system of record during workflows, with as-built redlines directing into the system of record, and data lags reduced to days. The solution would see a streamlined single source of record with future changes shared to the operational system through workflow-driven events.
