De Nora announces the launch of its next generation of ClorTec on-site sodium hypochlorite generators at Weftec, the Water Quality Event.

The new De Nora ClorTec DN Gen II electrochlorination system boasts a range of market-led features, designed to offer even greater on-site sodium hypochlorite generation efficiency, easier operation, less maintenance, and up to 50% footprint reduction. The Gen II continues a tradition of reliability and safety that can be expected after more than 3,500 ClorTec installations.

Upgrades to the ClorTec system include a new design that allows the duty and standby units to be mounted on the same frame, saving up to 50% on the footprint. Other improvements include 100% access to every component, making operation and maintenance simple, and a proprietary liquid flow backboard that can be located anywhere in the building for additional flexibility.

New features ensure optimal performance and efficiency including new non-intrusive level switch and temperature sensor design, optional split flow technology, and new water and brine flow controls. Additionally, Smart Monitoring technology and acid cleaning notifications allow users to remotely monitor, troubleshoot and control the operation of their system and provide operation and performance data remotely.

“De Nora has always prided itself on its electrochemical expertise, as an innovator with more than 355 patents and 3,000 regional extensions. The investment of time, knowledge and R&D resources in the De Nora Water Technologies product lines is returning some exciting results,” said Bryan Brownlie, Managing Director, De Nora Water Technologies Texas, LLC. “We have been listening carefully to the market to create a compelling new offering for our second generation ClorTec DN systems, addressing the concerns and needs of operators and engineering contractors alike. The launch at Weftec 2015 of our original De Nora ClorTec DN generators was just the first step towards this point and the process is always ongoing.”

For the rehabilitation of a drinking water pipeline in the district of Aalen, 200 km north-east of Munich, Germany, the Denso Group Germany protects weld seams from corrosion very quickly and efficiently using a new laying method that floats in water.

For this method, the pipeline was first laid in the water: Just ten minutes after applying the Densolen-AS50 tape system to the weld seam, the pipe was pushed into a tunnel flooded with water. The pipeline was then drained four months later. This is impressive as pipelines are normally not immediately and permanently exposed to corrosive media. The test results provided by the “Verband der Fernwasserversorgung” (Remote Water Supply Association) prove: The standard requirements of DIN EN 12068 for a high-quality protection of the weld seams are satisfied.

Direct flooding and extended operation in water are major challenges for field joint applications. This unprecedented method shows: The three-ply Densolen tapes fuse together very rapidly. A diffusion-resistant protective hose is quickly generated, with reliable performance even when permanently exposed to fluids. The single-tape system was applied in at least a three-layer wrapping using the engine-driven Densomat-11 application device.

The drinking water pipeline is one of the region’s main arteries. One of the two steel pipelines, with a nominal diameter of DN 1200, was restored for long-term use. Water flows through two parallel tunnels over almost two kilometres at 1,800 litres per second. The construction measure is expected to be completed in the spring of 2019.
