Reactivation in NORIT plants destroys adsorbed PFAS

Recognizable? Everyone who works at sea knows it: salt turns your engine into a rusty pile of misery that no longer works
The solution We therefore received the question from several customers: Do you have a solution for this? That is why we developed Kolmer Top Coating. This coating extends the life of the paint by a factor of four and anchors itself to the material through the paint layer. With this water-thin super strong layer (stronger than C3 or M5 coating!) the engine can withstand attacks from salt water and harsh weather conditions for years to come.

RedBox for Chemical Industries
Our client had a complex wastewater stream with chemicals, adhesives and minerals. The traditional approach, using flocculants and polymers and then air-drying the sludge, turned out to be less tenable. Bottlenecks were high chemical costs, poorly dewaterable sludge resulting in high disposal costs and a high chlorine content in the effluent. RedBox offered a smart, cost-effective solution. Our RedBox electrocoagulation technology purifies wastewater without the use of flocculants or polymers. During a test with our mobile pilot installation, the effect was immediately visible: reduction of the sludge volume by a factor of three. This immediately meant significant cost savings on sludge disposal and the purchase of flocculants and polymers. The effluent quality also improved considerably. Based on this successful pilot, Morselt designed and built a fully automated RedBox installation, precisely tailored to the customer's processes and with an optimal payback period. The result for the customer: • Drastically reduced sludge disposal and chemical costs • A stable and automated purification process • Cleaner effluent with lower chlorine content • A future-proof solution that is scalable and reliable. RedBox offers more than just water purification: it is a smart investment that reduces operational costs, improves environmental performance and prepares companies for the future.

Reduce operating costs with smart automation
Supporting asset management with smart automation can deliver additional savings. You can see the challenge we have faced with these two examples. (1. How can hundreds of pumping stations be monitored with minimal effort? (2. And how can maintenance costs be reduced without sacrificing quality? (1. We save on administrative costs by generating smart messages for administrators. The attached image shows an example of such a message. It shows how administrators are automatically informed about the functioning of hundreds of pumping stations. The performance of a pumping station is indicated on a scale from 0 to 100% functionality. The smart messages are generated periodically by the 4caster module in TeleControlNet. With these messages, administrators can see how all pumping stations function in an instant, without having to browse a central system to look up relevant information (if it is already available). If an administrator wishes to receive more information about a pumping station, he will be presented with an extensive technical location report at the touch of a button. 2. By switching from periodic to conditional maintenance. In conditional maintenance, the pump station itself indicates that there is need for service. This is done by automatic analysis of measurement data with the 4caster module. We have learned from experience that the average maintenance interval can be extended by up to 50% in this way. The starting point for the 4caster analysis is the reliability of data sets. We collect this reliable data in our end-to-end IoT solution with edge controllers (see Wikipedia "edge computing"). This approach is unique in the traditional telemetry world. The Inter Act edge controller is called TeleController and it continuously collects measurement data with small log intervals, making the reports from our 4caster very reliable.

Renovation of pumping station in Gouda
Years ago, Hoogheemraadschap van Rijnland started renovating the Gouda polder pumping station. Part of the renovation was to replace the old diesel engines in the pumps with a new electric drive system, with the goal of reducing CO2 emissions. Electroproject supplied a quiet electric motor with a frequency controller for this purpose. Electroproject has gained a lot of experience in electrifying polder pumping stations. As a solution, we recommended and supplied a low-noise electric motor of the slow-runner type. As a result, the mechanical gearbox could be eliminated, resulting in a higher efficiency of the drive system, lower CO2 emissions, and lower maintenance costs. The latter was possible because no maintenance was required for the gearbox. An additional benefit of the low-noise solution is that the pumping station is now also used as a museum and for educational purposes. An old diesel engine was left in place to show what the system looked like in the past. Hoogheemraadschap van Rijnland is pleased with the result. With the completion of the complete renovation, another hydraulic engineering work has been delivered that now and in the future contributes to keeping feet dry in the Rijnland area.

Repico® STFL DN1500 for Pressure Pipeline Bergen op Zoom
A football field, two meters underwater. And that within one hour. That is the amount of wastewater the installations at the pressure station in Bergen op Zoom pump every sixty minutes towards the treatment plant in Bath, Zeeland. The wastewater pressure pipeline between Moerdijk and Bath is the beating heart of regional water management. Distributed over two pipelines, together 60 kilometers long, wastewater from 35 villages and towns is transported at high speed to the treatment plant. To ensure this wastewater can continue to be transported safely in the future, several sections of the pressure pipeline have been renewed. Various pipe types with minimal tolerance space were precisely connected using five robust Repico® STFL DN1500 couplings. During the renewal of this pipeline, it was necessary to transition between existing PSK concrete pipes and Bonna Sentab VSP pipes to new GRP pipes. For this purpose, five Repico® STFL DN1500 couplings were produced.

Reverse pumping stations at Born. Electroproject delivers to the sustainability objectives of Rijkswaterstaat
By converting the pumping station pumps at Born, Electroproject has made an innovative contribution to the sustainability goals of Rijkswaterstaat. The conversion makes it possible to use the kinetic energy to generate electricity from the water that is discharged into the Born-Maasbracht Canal to maintain the level for shipping traffic in this Limburg canal. According to Rijkswaterstaat, the total package offered by Electroproject was favorable for two reasons: firstly, due to the combination of price/quality, and secondly because Electroproject proposed a low-voltage motor that does not require specially trained high-voltage technicians to maintain. Additionally, Electroproject provided a frequency converter that delivers the correct voltage to the network regardless of the pump speed. Together with the contractor responsible for renovating the locks, Electroproject proved to be a party that could provide excellent support to Rijkswaterstaat.

Rosenxt pioneers first drinking Water Line Inspection for Dutch utility Dunea
The pilot project focused on the Zoetermeer pipeline, which connects The Hague and Zoetermeer. Built in 1970, the five kilometer reinforced concrete and steel pipeline is a vital part of the region’s drinking water supply. For the first time, Rosenxt deployed two inspection robots sequentially in the same drinking water line – a so-called dual launch. The robots executed a successful robot-to-robot handoff during the live run, demonstrating a new level of precision and reliability. The inspection also featured the first real-world use of Rosenxt’s new above-ground marker system. This technology enables accurate tracking of inspection robots in the field and will be a key element of future operations.

Rotary screw blower in perfect harmony with turbo blowers
The wastewater treatment plant in Lüneburg in the state of Lower Saxony Germany, was designed to meet the needs of around 325,000 inhabitants. It features numerous treatment tanks up to 7m deep, where the air for the biological treatment processes is delivered via a control valve. Until recently, the compressed air for this aeration was generated by four conventional turbo blowers, each with a power output of 200 kW. However, the operator was looking for a new solution that would enable more wide-ranging, direct and dynamic control of compressed air production than the existing control system. They also wanted the benefits of a constant air supply that would not be affected by adverse weather conditions. Because the air flow and power consumption data are precisely tracked and logged, the benefits of the newly-installed rotary screw compressor quickly became apparent. The KAESER’s HBS series blower was subjected to a maximum usage test during the course of a one-year trial at the Lüneburg treatment plant. Because the existing control technology was set up for turbo blowers with adjustable guide vanes, the software needed to be adapted for a speed-controlled rotary screw blower. When the blower reaches a certain speed threshold, a turbo is switched on or off as needed to avoid inefficient overlapping. A direct performance comparison of the two machines shows us that, in almost 24-hour operation, including 12 hours running alone, the single blower matches the performance of a turbo delivering 4000 – 9000 m³/h. In terms of power consumption, the rotary screw blower, running in conjunction with the turbos, emphatically demonstrated that savings of around 250,000 kWh/year could be made, representing around 10–15% of the current annual total.

Safe, wear-resistant coating significantly extends the life of an electric motor
Kolmer Elektromotoren has developed a coating that should protect electric motors at least four times as long. The electric motor supplier's mission is to make motors more durable, now also in the water sector. "We're seeing a strong need in the water sector for this product," says Jan Bakker, sales manager at Kolmer Elektromotoren. The idea for a new coating arose about six years ago. Due to seawater and aggressive cleaning agents, existing coatings didn't offer long-term protection for marine engines, resulting in deposits, overheated motors, and peeling coatings. Wasn't there a coating that lasted longer than six months? "No," says Bakker. "Then we started developing our own coating in Germany." The idea for a new coating arose about six years ago. Due to seawater and aggressive cleaning agents, existing coatings didn't offer long-term protection for marine engines, resulting in deposits, overheated motors, and peeling coatings. After a thorough development phase, the company suspended two engines in seawater: one coated and one uncoated, where they were exposed to the effects of ebb and flow and wind for 120 days. "The difference between the two engines was unprecedented; the uncoated engine was covered in algae and shellfish. The engine with our coating had a small deposit, but I easily cleaned it with a toothbrush," says Bakker. Tests with aggressive cleaning agents, acids, and ammonia followed, which were also passed. Because no paint flakes are released and the coating's composition has been deemed safe for humans and the environment, it received a food safety certificate and the go-ahead from TNO for production. Bakker: "The first test engine, which previously had to be replaced every six months due to flaking paint and rust, is still running six years later thanks to the coating."
