Five years of reverse osmosis membrane elements from LANXESS in Bitterfeld

“Our foray into the reverse osmosis (RO) membrane business five years ago has truly been a success story. We have almost reached the limit of our current capacity so we are going to double production capacity in the coming year,” said Jean-Marc Vesselle, head of the LANXESS Liquid Purification Technologies (LPT) business unit, on the occasion of a celebration of the five-year anniversary of the Lewabrane plant operated by IAB Ionenaustauscher GmbH, a wholly owned subsidiary of the LANXESS specialty chemicals company. “The Lewabrane brand has established a firm place for itself in the market, not least on account of its high quality and performance properties, which both we and our customers expect from ‘Made in Germany’ products,” he added.

The specialty chemicals company has invested a total of 40 million Euros in the site in the last five years alone. In addition to the membrane elements plant, LANXESS also operates the world’s largest ion exchange resin plant in Bitterfeld.

“Here in Bitterfeld-Wolfen, LANXESS is truly writing history, something we are really proud of. As a company with a long tradition in water treatment, LANXESS has grown steadily and now occupies a leading position in the market,” said Petra Wust, mayor of Bitterfeld-Wolfen, continuing: “Part of the company’s philosophy has always been its regional commitment and special bond with Bitterfeld-Wolfen, and I am extremely grateful for that. I wish the company a great deal of continued success!”

Vesselle emphasized the company’s association with the site and the region. “In 2011 – before the membrane plant – we had about 100 employees in Bitterfeld. That number has now grown to about 160 and will continue to increase. We value the skills, commitment and reliability of the workers here, which is a key element in our success.”

Expansion of capacity to meet increasing demand

The market for RO membrane elements is currently projected to grow at an above-average rate of 10 percent annually in coming years (CAGR 2015-2020). Because the plant is already operating at almost the limit of its capacity, LANXESS has decided to double the corresponding capacity at the Bitterfeld site. The additional capacity is scheduled to come on line in the second half of 2017. The expansion will create up to 10 new jobs.

Commitment to research, training and development

LANXESS is demonstrating its commitment to the Bitterfeld site in a number of different ways, including in Research & Development. In this regard, Vesselle said: “We are continuously conducting research in all areas of modern water treatment so that we can continue to provide our customers with the requisite expertise from a single source.” For that purpose LANXESS is cooperating with technical universities and other research facilities in the region such as the Fraunhofer Institutes for Factory Operation and Automation (IFF) in Magdeburg and for Microstructure of Materials and Systems (IMWS) in Halle.

A total of 18 apprentices have started their careers with IAB Ionenaustauscher GmbH since the site was expanded, with eight currently in training. After completion of their training, these chemical production technicians, chemical laboratory assistants, industrial mechanical engineers and electrical engineers for automation technology can look forward to promising careers, not least with the company itself. Of the 10 apprentices who have already completed their training seven were taken on.

Comprehensive water treatment expertise

LANXESS is one of only two companies in the world that offer know-how and products both in membrane elements and ion exchange resins. “With this comprehensive water treatment capability we can meet the requirements of customers all over the world,” Vesselle remarked. The membrane element plant is the logical continuation of a tradition dating back almost 80 years in Bitterfeld-Wolfen. The industrial production of ion exchange resins began there in 1938, and after the Second World War the Lewatit brand became famous worldwide. LANXESS operates additional production facilities for ion exchange resins in Leverkusen, Germany, and Jhagadia, India.

Because membrane and ion exchange technology frequently go hand in hand, the development and introduction of the LewaPlus integrated design software was a major contribution to optimally linking the strengths of both technologies. The software, which is continuously being expanded and refined, reflects LANXESS’s comprehensive know-how in the field of water treatment.

Membrane elements for a wide range of applications

LANXESS has continuously expanded its line of membrane products since production began in September 2011 and the products were introduced to the market in early 2012. Numerous types of elements are available in different sizes and can be optimized to be particularly fouling-resistant or energy-efficient or for high performance.

That opens up a wide range of applications for the company and its customers in the treatment of process water and wastewater in many different industries. An additional important area of application is the recovery of potable water from brackish or seawater. LANXESS and its products make important contributions in this field, facilitating access to clean drinking water for an ever-growing world population.

“In addition to the quality and performance of our products, the innovative spirit and creativity of our employees have been particularly responsible for our membrane elements establishing a firm place in the market in just a few years,” Vesselle said. One example of this innovation is a new type of multi-function spacer inside the membrane elements. This “feedspacer” consists of filaments of different thicknesses, which explains the designation “Alternating Strand Design” (ASD). It was brought to market in record time and is now helping to increase the energy efficiency of the corresponding membrane elements and simultaneously optimize fouling resistance.

The LANXESS Liquid Purification Technologies business unit

The LANXESS Liquid Purification Technologies (LPT) business unit currently employs 500 people worldwide, more than 300 of which work in Germany. LPT is part of LANXESS’s Performance Chemicals segment, which recorded sales of EUR 2.0 billion in 2015.

Filtration leader wins significant contract with US microelectronics giant

One of the world’s leading producers of high performance filtration and separation technology has won a significant contract to supply a US-based microelectronics giant.

Porvair Filtration Group’s Boise Division, formerly TEM filters, is producing almost 4,500 filters for the global semiconductor design and manufacture specialist – mobilizing operations in record time to meet the challenge.

Porvair’s GasPro™ 500 filter’s unique benefits were identified by a well-known supplier of sophisticated silicon wafers as an ideal solution for the required retrofit application.

This highly efficient, high-performance filter is a PTFE membrane-based product that is sized for 25 scfm gas flow applications.

The filter is primarily used in Nitrogen purge gas, CDA, and many process gas applications.

The Gaspro 500 is now being retrofitted to a particular tool that utilizes Clean Dry Air, with the filtration leader ensuring that it is compatible with the four types of connections used by the original equipment manufacturer.

The leading manufacturer of microelectronics devices – whose analog and embedded processing products power electronics within many industries – was keen to realize marked energy savings as it looked to push air with less pressure drop across the filter, making Porvair’s Gaspro 500 series the desired choice.

The contract commenced with first deliveries in early June and was completed in early August.

President of Porvair, Kevin Nelson, said: “We are proud to be working with one of the largest and most innovative companies of its kind, delivering high quality solutions that help to realize value and drive greater efficiencies across its global operations.

“We are confident in our ability to deliver further value to the semiconductor design and manufacture leader as part of what we hope will be a strong and enduring relationship.

“The win also bears out our wider commitment to delivering fresh innovation to the semiconductor industry following significant investment in our Boise Division.”

Porvair Filtration Group – which has supplied the aerospace, nuclear, energy, process and bioscience industries with performance-driven filtration equipment for nearly 50 years – manufactures in both the US and UK and has an extensive network of sales offices and distribution channels throughout the world.

A revolution in corrosion protection

Viledon Honeycomb modules fitted with Versacomb media – revolutionary technology to protect against corrosion.

The unique Viledon Honeycomb modules with activated carbon are now available in Europe

Thanks to a new technology, Freudenberg Filtration Technologies has set new standards in corrosion protection. Known as Viledon Honeycomb, the new modules and system solutions ensure operational security anywhere that process-related harmful corrosive gases occur and threaten sensitive electronic devices and equipment. Honeycomb system solutions are already being used successfully in America, where Freudenberg Filtration Technologies is the market leader in the US petrochemical industry. Now this innovative technology is also available in Europe.

All sorts of noxious gases, from hydrogen sulfide and sulfur oxides to ozone, cause corrosion in electronic components. The negative consequences include reduced process efficiency, additional maintenance costs, expensive repairs and unplanned downtime.

Tried and tested in gas phase filtration, Viledon ChemControl pellets reliably eliminate acidic pollutant gases from intake and recirculating air. Viledon Honeycomb modules complement this portfolio. Alongside their performance and reliability, they offer a number of other advantages. Pressure loss when air is flowing through the filters is extremely low, making them particularly economical and energy efficient. Reminiscent of a honeycomb structure, their compact form also saves space in very cramped conditions, such as on oilrigs. The modules are also particularly user-friendly, easy to install in standard filter housings and can be simply maintained without additional aids. Change intervals can be determined in advance, based on the environmental conditions. “With Viledon filterCair, we offer customers a fully customized service package that can include corrosion protection as well”, explained Dr. Ren├® Engelke, Market Segment Manager Gas Phase Filtration at Freudenberg Filtration Technologies.

The future of air cleaning

Viledon Honeycomb modules consist of channels arranged in parallel, through which the process air passes. Walls made of activated carbon powder separate the channels from each other. The walls are less than a millimeter thin and are held in shape by ceramic binders. The distance between carbon and process air is therefore minimal, allowing highly efficient filtration performance at high flow velocities.

This sophisticated structure points the way to the future of air cleaning. Following the company’s success in America, Freudenberg Filtration Technologies has now equipped well-known reference customers in Europe with Viledon Honeycomb modules and system solutions for the first time.

Filtration Industry Growth to Be Celebrated at INDA’s 25th Annual Filtration International Conference & Exposition

INDA will celebrate the strength and growth of the filtration market at its 25th anniversary edition of the Filtration International Conference & Exposition in Philadelphia this fall.

Started as a small conference in a hotel setting in 1991 by INDA, then in collaboration with the American Filtration & Separations Society, the Filtration International Conference & Exposition has become the industry’s most important filtration event in North America.

Filtration 2016 will be held Nov. 8-10 at the Pennsylvania Convention Center in Philadelphia. Attendees will toast the 25th anniversary milestone at the industry reception Nov. 9, from 5 to 6 p.m., on the show floor. Business engagement will continue throughout the exposition where industry participants from around the world and across the supply chain will have the opportunity to connect with buyers and decision makers.

A special 25th anniversary seal and Filtration logos created by INDA to commemorate the occasion can be used by exhibitors in their marketing. They are Filtration-25th-Anniversary-BlueGradientavailable on INDA’s website:

The Filtration International Conference & Exposition has experienced dramatic growth from 200 delegates with 20 tabletop displays in its first year to 1500 attendees and more than 140 exhibitors last year.

“As INDA celebrates the 25th edition of Filtration, we reflect upon the incredible breadth of innovations, new technologies, and advancements that have taken place over the past few decades,” said Dave Rousse, INDA President. “This milestone is extremely important as it shows the vitality and health of the filtration industry to support this annual international business event for 25 years.
