Fundamentals for cleaner and healthier air

A World Bank study maintains that air pollution costs the world trillions of dollars a year and contributes to the premature death of millions of people a year around the world. Ambient air pollution remains the fourth leading cause of premature global deaths, causing lung cancer, heart disease and respiratory problems. Air quality problems are growing in many developing countries, whose development is being severely impeded by this, with more than 85% of the global population living in areas where World Health Organization (WHO) air quality guidelines are exceeded. According to WHO air quality guidelines, pollution should be restricted to a daily particulate matter of 25 micrograms per cubic meter. However, in February, Beijing and New Delhi typically see daily levels at or above 300 micrograms per cubic meter – 1,200% higher than WHO guidelines. Despite previous policy efforts that have been successful in reducing particulate matter and trace gases in North America and Europe, adverse health effects are still found at low levels of air pollution.

Governments, the private sector and people will all need to work together to find solutions to this prevailing problem. The nonwovens industry has been making tremendous strides in the development of more effective media for air filtration, to for example improve indoor air quality.

Visitors and exhibitors at INDEX™17, the world’s leading nonwovens exhibition held in Geneva from 4th-7th April 2017, will have the chance to hear from “Big Picture” speaker, Prof. Nino Künzli, Deputy Director, Swiss Tropical and Public Health Institute, Dean, Swiss School of Public Health, on the health effects of air pollution and the implications for policy makers, citizens and the industry. “The global scientific community has made enormous progress in understanding the health effects of complex air pollutant mixtures and the methods to quantify the public health impact are now widely used both globally and locally,” said Prof. Nino Künzli. “However, lining up policy actions with science to protect public health remains a challenge to be addressed by the global community of researchers, industry and policy makers.”

INDEX17 will take place in parallel to partner filtration conference and exhibition FILTREX™ for the first time this year. The free opening session of the conference on 5th April will feature keynote speaker Prof. Nino Künzli, who will put forward the key challenges and opportunities faced by the filtration industry, and renowned experts in the field will then discuss how these are being addressed, including through the use of nonwovens.

Key topics covered at FILTREX include:

  • Health effects of fine and ultra-fine particles on humans
  • Standardisation
  • Quality assurance and testing
  • Fibres for filtration media
  • Application oriented solutions

LANXESS forms distribution partnership with Kolar Filtration, LLC for aquarium water treatment

LANXESS Sybron Chemicals, Inc., the U.S. subsidiary of LANXESS Corporation and responsible for representing the Liquid Purification Technologies (LPT) business unit of global specialty chemicals company LANXESS, has entered into a distribution agreement with Kolar Filtration, LLC for sales of Bayoxide granular ferric oxide (iron oxide hydroxide) and Lewatit ion exchange resins into the U.S. aquatics market.

Bayoxide E33 and E33 HC are ferric oxide adsorbers developed specifically to remove phosphates from water. In aquariums, excessive phosphate levels cause increased algae growth in freshwater aquariums and serious harm to fish and corals in saltwater aquariums.  Bayoxide adsorbers quickly and effectively reduce phosphate concentration in the water. Lewatit ion exchange resins are used as polishers at the last stage of reverse osmosis systems. They remove total dissolved solids (TDS) from effluent water coming from the reverse osmosis system, making it ultrapure. The aquarist is then able to add back the minerals into solution to make aquarium water devoid of impurities.

The products are sold online under the Kolar Labs brand and are shipped individually packaged, private labeled, or in bulk.

“LANXESS Liquid Purification Technologies provides a portfolio of water treatment solutions serving key industries such as industrial wastewater, power generation, food and beverages, mining, and ultrapure water for electronics. This new distribution agreement with Kolar Filtration helps us to reach into the consumer aquarium market, allowing us to diversify our sales. We see this as a complimentary fit and are happy to have Kolar as our partner,” said Firuza Mir, president and CEO of LANXESS Sybron Chemicals, Inc.

“Kolar Filtration is excited about our agreement with LANXESS. This agreement allows Kolar to expand distribution channels such that the benefits of Bayoxide media and Lewatit ion exchange resin can be available to all aquarists with consistent instructions for use, performance claims, inventory availability and product quality,” said Richard Renjilian, Kolar Filtration president and founder.

Kolar Filtration, LLC is located in Wheeling, Illinois. The company provides a single source of high quality filtration media for the aquatics market to distributors, retailers and end-users under the Kolar Labs brand in bulk or packaged quantities.

The Liquid Purification Technologies (LPT) business unit of specialty chemicals company LANXESS is one of the most important suppliers for liquid separation products worldwide. With Lewatit ion exchange resins, Bayoxide iron oxide adsorbers and Lewabrane RO membrane elements, LANXESS holds a leading position in the development and production of three premium separation technologies for water purification, desalination and process stream treatment.

Freudenberg filter business celebrates 60 years

Comparing past and present: Freudenberg exhibition stand, filter mats production and Freudenberg location in Weinheim

This year, Freudenberg’s filter business will be celebrating an anniversary. Sixty years ago, the pioneer in nonwovens wrote the first chapter of a new success story with the introduction of nonwoven filter mats. From these beginnings, a flourishing business developed, which has been operated since 2009 by an independent company: Freudenberg Filtration Technologies. With around 2,300 employees at more than 30 locations, the company is today one of the world’s technology leaders in filtration technology.

Setting trends with innovations

The history of the filter business at Freudenberg has been characterized by technical innovations and market trends since 1957, which the company itself has set. Examples include the development of the synthetic Viledon® compact pocket filters in the 1970s as well as a good decade later the launch of micronAir® automotive cabin air filters. Freudenberg was the first ever supplier to ensure that no dust, soot, pollen, noxious gases and unpleasant odors could enter the interior of vehicles. To this day, micronAir® is the world market leader in the automotive business.

Holistic system provider

What started life as a pure supplier of filter materials has steadily evolved over the decades. Complete cassette, pocket and HEPA filters, filter bags and cartridges have gradually been added to the range. Today, Freudenberg Filtration Technologies specializes in holistic system solutions, which comprises of the engineering, construction and operation of complete filtration plants, including a comprehensive package of services with online monitoring and on-site service technicians.

Technical diversity

The nonwoven medium still plays a significant role in air filtration and is being continuously developed. For example, for several years, Viledon® NEXX filter bags have been fulfilling demanding dust removal tasks in steel works or foundries in a particularly resource-conserving and energy-efficient manner. The basis for this is the filter medium itself: a form of Evolon® optimized for this application. Evolon is a nonwoven made from microfilaments and was developed and patented by Freudenberg.

Complete service portfolio

In the area of gas-phase filtration for protecting sensitive electronics against corrosion or the treatment of effluents in dairies or whisky distilleries, completely different technologies now supplement the original nonwoven filter medium: for example, ChemControl pellets, Honeycomb modules or Aquabio membrane bioreactors. Freudenberg Filtration Technologies has successfully extended its service portfolio in recent years from its original concentration on the filtration of air particles to completely new applications of this kind. This development into a comprehensive range of products and services from a single source is unique on the market and is a key success factor for the current filter business at Freudenberg.

Global set-up

A further area of focus was and remains early-stage globalization. In the Japan Vilene Company, Freudenberg found a reliable partner in the nonwoven and filter business as far back as the 1960s. Among other regions, the fruits of this strategic partnership are currently visible in China, where Freudenberg and the Japan Vilene Company have been present for 20 years and are producing filters for customers in the Far East at three locations – three of more than 30 sites around the world, through which Freudenberg Filtration Technologies is represented in all relevant markets.

Sustainable solutions for many industries

Filtration technologies from Freudenberg currently ensure clean air, pure gases and liquids in many industrial sectors: in vehicles, gas turbines and compressors, surface treatment, the food and beverage industry, healthcare, petrochemicals and mining. Innovative filtration technologies make processes cleaner, safer and more energy-efficient everywhere. Freudenberg’s aspiration is to use its knowledge to support the long-term business of its customers as comprehensively as possible, thereby ensuring greater quality of life. In this way, filtration solutions from Freudenberg have been helping to protect people and the environment against pollution and conserving natural resources for 60 years.

Nonwovens to control our immediate environment

According to a 2015 study by EDANA, the international association serving the nonwovens and related industries and the sponsor of the INDEX™17 show, the nonwovens filtration market is expected to grow from $3.5 billion in 2014 to $4.6 billion in 2019, representing an annual growth rate of 5.6%, making filtration one of the fastest growing markets for nonwovens.

An increased awareness of the need to control our immediate environment at home, in the workplace or while traveling, leads filters to play an essential role in our everyday lives. Noora Blasi, Marketing Manager, Engine and Industrial Filtration and Advanced Filtration at Ahlstrom is convinced that, “Changes in demographics, in the healthcare industry, and in resource scarcity are the key drivers contributing to the changing needs of end users.”

Clean air and drinking water, infrastructure improvements as well as the replacement of textiles and paper filter media, make filtration the fastest growing market for nonwovens. Automotive filtration remains the largest application for nonwoven filter media, followed by water and air filtration.

Visitors and exhibitors will gather at INDEX17, the world’s leading nonwovens exhibition, in Geneva from 4th-7th April 2017, to gain first-hand knowledge of the latest developments in nonwovens for filtration applications, with exhibitors showcasing the astonishing functional qualities of these versatile materials. For the first time, FILTREX™, the leading conference and meeting point for the filtration industry will take place at PALEXPO in parallel with INDEX17 (5th-6th April), thus bringing together the worlds of filtration and nonwovens.

The deadly cost of air pollution

According to a 2016 World Bank study “The Cost of Air Pollution”, carried out in co-operation with the Institute for Health Metrics and Evaluation (IHME) at the University of Washington, air pollution costs the world trillions of dollars a year and severely impedes development in many countries. The World Bank found that in 2013 – the year from which the latest available estimates date – the annual cost of dirty air to the United Kingdom was $7.6 billion, to Germany $18 billion and to the United States $45 billion. In addition, the study reveals that air pollution is still the fourth leading cause of premature deaths worldwide, causing lung cancer, heart disease and respiratory problems. Air pollution must be made a priority and governments are slowly changing their legislation. Many factories worldwide have enforced the installation of filter bags – between 10,000 – 25,000 of these are employed in the average coal plant in China.

Indoor air pollution, the next challenge

Air pollution is a common issue in industrialized countries, however this problem does not stop at your doorstep. A growing body of scientific evidence indicates that the air inside homes can be even more polluted than outside. Such is the case in even the largest and most industrialized cities.

Solvents used to treat furniture, emissions produced from cooking, household products and soot from candles are among the long list of pollutants that can be found inside the home. This presents new opportunities for nonwovens. Filters made from nonwoven fiberglass and activated carbon – with rapid adsorption dynamics – are now being used by a number of forward-looking hotel chains in Europe now, often employing low-energy nonwoven air filters … and this is only the beginning.
