The new bi-component PPS media forms a strong bond when laminated with GE’s Preveil expanded polytetrafluoroethylene (ePTFE) membrane.

‘A stronger membrane bond can improve filtration performance by helping achieve lower emissions for longer periods. It can contribute to better differential pressure and improved energy consumption because fewer cleaning cycles and a lower pulse pressure are needed,’ explained Ladwig.

To produce the media, a high-strength, high-temperature polymer is surrounded by a sheath of PPS to create bi-component fibres, which are turned into felt. This is the preferred substrate for fabric filters used in a bag-house, which is part of a power plant that generates electricity by burning coal.

Vishal Bansal, principal engineer for GE Power & Water, Air Filtration, added: ‘The new core delivers added strength over a traditional, all-PPS fibre. Together, the polymer core and its PPS sheath provide chemical and temperature resistance. While ‘core/sheath’ fibre technology has been around for a number of years, our unique combination is a new innovation for our customers.’

DW & PS opens plant for Tequatic Plus filters and wins award

Dow Water & Process Solutions (DW & PS), a business unit of

Dow Chemical Co, recently opened a commercial-scale manufacturing plant in Menlo Park, California, USA, for its Tequatic Plus range of fine particle filters. The firm also reports that the composite housing used for its Tequatic Plus F-50 filter has won an award.

The new production facility, which is designed to meet growing demand for the F-50, F-75 and F-150 models, is owned and operated by Clean Filtration Technologies Llc (CFT), a wholly owned subsidiary of Dow.

Abhishek Shrivastava, Engineering Manager, CFT, said: ‘The new facility reflects a five-fold increase in floor space, most of which is dedicated

to manufacturing, and research and development. It will also house a growing team of water filtration experts.’

‘Importantly, the facility includes a state-of-the-art application development laboratory that will enable us to speed up R&D and product testing, to bring products to market faster than ever before.’

DW & PS describes the Tequatic Plus filter as a breakthrough, patented technology that combines, in a single device, the power of continuously cleaning, cross-flow filtration with centrifugal separation and solids collection. According to the firm, it is designed to handle difficult-to-treat feed-water containing high and highly variable total suspended solids (up to 10 000 mg/l) much more cost-effectively and consistently than traditional technologies.

Cedella Beazley, General Manager, CFT, said: ‘Orders are already being filled in a variety of applications where Tequatic Plus is used as a primary filter, as a pre-filter for applications such as reverse osmosis and ultrafiltration, or even as a post-filter in moving-bed bioreactor (MBBR) systems.’

‘Its use in MBBR systems is the most recent application to benefit from the product’s features. It is being integrated into systems for use in five hospitals based in Iraq to help meet stringent requirements for treating wastewater before it is discharged into rivers,’ continued Beazley.

‘The customer found that the Tequatic Plus filter offered a variety of advantages over multi-media – including low maintenance, high up-time and the ability to simplify its system in a way that reduced the overall footprint.’

John Patrin, Strategic Marketing Manager, CFT, added: ‘The Tequatic Plus filter is also proving its value in other areas, such as oil-field water.’

‘In addition to low maintenance and high up-time, customers are attracted to water recovery that is typically greater than 99%, low consumables and disposal costs, and low environmental impact. The filter is being used in applications with space and weight constraints, such as in pre-filtration systems for producing drinking water on board oil platforms.’

The Tequatic Plus F-50 filter recently received an ‘Infinite Possibility for Market Growth’ award in the Market Growth Category of the Awards for Composites Excellence (ACE) programme, which was organised in conjunction with the Composites 2013 Exhibition and Convention.

The award was presented to key supplier

Ershigs Inc for creating a product that demonstrates the potential to notably increase the use of composites in existing or developing markets, while also exemplifying innovation, creativity and commercialisation. Ershigs worked closely with CFT to produce the housing for the F-50 filter.

‘The design and production of the composite material is key to the success of the Tequatic Plus filter, and we are elated that Ershig’s submission was successful and that our product received this award,’ said Beazley.

Hyflux signs MOUs for projects in China’s Yunnan Province

Hyflux Ltd’s wholly-owned subsidiary Hyflux Investment

Consultancy and Management Service (Tianjin) Co Ltd has signed two memoranda of understanding (MOUs) to work with the prefec-tural governments of Chuxiong and Qujing in Yunnan province, China, to develop water and environmental projects in the two cities – including Chuxiong Development Zone, Luliang Industrial Park and local townships.

The projects covered under the MOUs include the development of water recycling, wastewater treatment plants and potable water treatment plants, and related infra-structure. They will adopt Hyflux’s Kristal ultrafiltration (UF) membrane technology.

The total investment value for the pro-jects in Qujing and Chuxiong is estimated to be approximately ¥1.2 billion and less than ¥2 billion, respectively. They could be developed by Hyflux and/or its potential partners.

The MOUs will pave the way for closer

cooperation between the prefectural govern-ments and Hyflux. Chuxiong and Qujing will gain from Hyflux’s expertise in develop-ing water treatment facilities that are able to meet stringent water-quality standards and protect the environment, while produc-ing water that is affordable and accessible to industries and communities. Hyflux, on the other hand, will be given the opportunity to strengthen its position in Yunnan province.

Chuxiong is situated in north-central Yunnan and lies to the west of Kunming, the capital city of Yunnan. Qujing in east-ern Yunnan is an important industrial city and the second largest by population after Kunming.

Report examines India’s wastewater reuse sector

A report entitled ‘Wastewater Reuse and Recycling Equipment

Market: India’ is now available from MarketPublishers Ltd. It provides his-torical and forecast data for the period 2010-2018.

According to the study, the country’s wastewater reuse and recycling equipment market was valued over US$140 million in 2011, and it is expected to expand at double-digit year-on-year growth rates – driven mainly by water scarcity, increasing aware-ness, governmental regulations, advantages of ‘‘green’’ technology and enhanced product quality market-wide. However, the market’s fragmented character poses a major challenge to its smooth development, often forcing down pricing and marginal revenue, says the firm.

The report presents estimates of the market size by technology type, revenue forecasts, market drivers and restraints, market share percentages for top manufacturers, and quo-tations from industry players, covering expe-riences of operating in the market place.
