showcase Pentair launches residential caPdi/rO system Pentair Inc revealed the first fruits of its investment in Dutch company Voltea BV when it unveiled on 1 October 2011 its new Hybrid Deionization (Hybrid DI) system with CrossCharge technology. Pentair claims that this is the first electronic water purification system that is practical for residential applications. Hybrid DI systems will be the first to offer consumers the combined benefits of a reverse osmosis system and a water softener without requiring salt. The company has exclusively licensed and renamed Voltea���s capacitive deionization (CapDI) technology for residential and light commercial applications for point-of-entry products. As explained in D&WR (May/June 2011, page 26), the technology uses capacitive electrodes to remove hardness and purify water without employing salt. The renamed CrossCharge technology within the Hybrid DI system is driven by a Pentair developed, advanced microcontroller using an array of sensors to monitor and manage all system and water quality parameters in real time. The technology continuously assesses the inlet and treated water quality, controls the power supplied to the stack, and adjusts operating cycles and system flows to continuously optimize performance. The controller includes self-diagnostics and auto clean cycles. It also features a full-color touch screen user interface with animated ���User��� displays that are intuitive for the everyday user/homeowner and interactive ���Technical��� screens for system maintenance providers. Pentair���s vice president for technology, Phil Rolchigo, hailed the product���s launch as an important milestone for the global corporation. ���Being first to market with this innovative technology is an excellent illustration of Pentair���s ongoing leadership position in the water treatment industry,��� he said. mann+hummel installs fOur Pes membrane PrOductiOn lines Four new production lines for polyethersulfone (PES) membranes have been added to the Singapore plant of Mann+Hummel and an extension is already being planned. Mann+Hummel plans to use the PES hollow fibres for new application areas within its water business, such as the food and beverage industry and in the field of biotechnology. In the field of beverages and biotechnology, fouling (deposition) due to filtered substances is common. The cross-flow flow Klar series membranes in Mann+Hummel���s Singapore factory | 36 | Desalination & Water Reuse | February-March 2012 guidance of the PES hollow fibre acts against this. It generates a cross-flow along the membrane with high speed and automatically carries the fouling products with it. Mann+Hummel uses PES membranes and a new skid design in ultrafiltration systems like its Klar-series. The Klar-series is suitable for the treatment of process and service water for small rural communities, towns and villages, hotels and resorts and also for the treatment and recycling of industrial process and waste water. It removes foreign particles, and bacteria with a turbidity of less than 0.1 NTU. Maintaining the turbidity under 0.1 NTU means that the system delivers a consistent supply of fresh, clean water on time and every time. new website launched by membrane maker A new website has been launched by desalination and waterreuse membrane system supplier Koch Membrane Systems Inc (KMS). The new site, www.kochmembrane.com, is designed to give users clear and easy access to content while supporting the depth of the company���s expertise. The KMS website is structured around the company���s two major business segments: Industrial & Life Sciences, and Water & Wastewater. The Systems and Service groups are also highlighted, allowing customers to read that KMS provides superior technical and customer service support in addition to a broad range of membrane filtration solutions. German Pes membrane mOdule fOr uf intrOduced A polyethersulfone (PES) ultrafiltration (UF) membrane module, the Liqui-Flux�� W10 has been introduced by Membrana GmbH, based in Wuppertal, Germany. Using inside-out operation with 75 m2 of membrane area, this new module design is both functional and durable and also features the innovative Variable Connect Concept - VCCTM. The introduction of VCCTM into Membrana���s Liqui-Flux�� W10 UF module allows system integrators to select from a variety of connection options to accommodate for the many space limitations and different water qualities faced in the field. Configurations include: l The Standard Setup, which features a radial feed inlet port and axial concentrate port. This configuration is ideal for treating a broad range of feedwater qualities. l The Compact Setup, which uses two radial ports and is only 1.5 m in height. This configuration is well-suited for installation in areas with height limitations. l The Optimized Footprint Setup, which uses an axial-feed port. This reduces the space between modules, thereby reducing the overall system footprint. By using this configuration a 4.75 m2 module skid with 2,100 m2 membrane area can be built. The flexibility of being able to choose a configuration that meets specific onsite needs allows system engineers to build more cost-effective systems with a smaller footprint. All configurations can operate in dead-end mode. The Standard Setup and Compact Setup can operate in cross-flow mode. Additionally, a second filtrate port can be added and end caps are designed with flat, rectangular surfaces to allow for easy mounting and connecting to other modules. Ports are available in 73 mm, 75 mm and 76 mm sizes to meet regional dimension requirements.
