Microdyn-Nadir introduces robust BIO-CEL MBR module
G
ermany’s Microdyn-Nadir GmbH, a global supplier of membrane products, and the water treatment business unit of Mann+Hummel, has launched its newly-improved MICRODYN BIO-CEL® membrane bioreactor (MBR) module. The company says factory tests suggest that recent innovations applied to this latest module – the MICRODYN BIO-CEL L-2 MBR – make it substantially more robust compared with older designs. The BIO-CEL MBR module is described as a true hybrid technology that brings together the best features of hollow-fibre and flat-plate configurations. For example, maintenance cleaning requirements are potentially 83–95% less than leading hollow-fibre technologies, claims the company. The main advantage is an unprecedented resistance to clogging. Microdyn-Nadir used the Water Environment Federation’s Technical Exhibition and Conference (WEFTEC), which was held during September to showcase its latest MBR module. Launched in 2005, there are now over 500 installations of BIO-CEL modules worldwide, including more than 50 plants in the USA alone, says the firm. The company used IFAT 2018 – a major trade fair covering water, sewage, waste and raw materials management – to unveil the open design of its MICRODYN BIO-CEL module L. This module offers 360° access, which makes the membrane system easier to clean and maintain. This design also means that it has a longer service life and its performance does not diminish over time (Membrane Technology Volume 2018, Issue 6, June 2018, page 2). Four years earlier, at IFAT 2014, it launched its BIO-CEL XL – the larger version of its BIO-CEL submerged module for MBRs (Membrane Technology July 2014, page 3).

De Nora’s latest sodium hypochlorite generator delivers further cost savings

e Nora, a designer of water disinfection and oxidation, and filtration
and electrochlorination systems, has launched its next generation of ClorTec® on-site sodium hypochlorite generators. Introduced at this year’s Water Environment Federation’s Technical Exhibition and Conference (WEFTEC), which was held on 23 September in Chicago, Illinois, USA, the latest high-efficiency ClorTec Gen III system uses an optimised electrochlorination process that reduces salt and power consumption to deliver a 15% operating cost savings over the previous ClorTec DN Gen II system (Membrane Technology November 2018, page 3) that was launched last year at WEFTEC 2018. This latest system includes the same features as the previous model, including easy operation, less maintenance and a reduced footprint of up to 50%, says the firm. All ClorTec systems 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. Smart monitoring technology and acid cleaning notifications also enable users to remotely monitor and control the operation of their system and provide performance data remotely back at the operator’s location. The ClorTec line of on-site sodium hypochlorite generators produce sodium hypochlorite using three common and safe consumables – water, salt and power – and has proven effective at producing chlorate and other disinfection byproducts levels in finish water below the current US guidelines and international regulatory limits. Earlier this year De Nora acquired US-based MIOX Corp – which specialises in electrochemical generation systems for water disinfection – from Johnson Matthey (Membrane Technology March 2019, page 16). MIOX technology added knowledge and experience of producing proprietary mixed oxidants on-site for advanced applications. ‘With more than 9500 installations globally, De Nora has been pioneering the brine electrochlorination process for nearly a century, since filing the first of several patents covering hypochlorite generation,’ said Dr Mirka Wilderer, CEO, De Nora Water Technologies. Dr Wilderer continued: ‘The new high-efficiency system uses less salt and less power, resulting in significant OPEX cost-savings for our partners. With simple and precise operation, the ClorTec Gen III offers the same peace of mind as the Gen II, but now reduces operating costs by 15% – that can result in yearly savings of $70 000, based on a 3000 lb FAC per day system.’ For further information, visit: www.denora.com/products/brine-system/clortec.html
