Donaldson reports Q2 earnings – Engine Products up, Industrial Products down

Donaldson Company, Inc. reported second quarter 2021 net earnings of $56.2 million compared with $64.4 million in 2020. The current period included charges of $14.8 million related to restructuring activities initiated in the second quarter, primarily in Donaldson’s Europe, Middle East and Africa (EMEA) region. Adjusted net earnings were $66.8 million. Generally Accepted Accounting Principles (GAAP) earnings per share (EPS) for the second quarter 2021 were $0.44 and were $0.50 in 2020. Excluding the impact of restructuring expense, second quarter 2021 adjusted EPS were $0.52.

“Our second quarter results demonstrate the advantage of our diversified portfolio of businesses that allow Donaldson to benefit from cyclical end-market recovery while mitigating the effects of weaker markets at different points in the cycle,” said Tod Carpenter, chairman, president and chief executive officer. “We are executing our strategy to expand our total addressable markets to further enable Donaldson to leverage our filtration technology leadership position, and we are well-positioned to benefit from the post-pandemic recovery.

“We are encouraged by the robust growth in our Engine Off-Road and Aftermarket businesses, which contributed to stronger-than-expected second quarter sales, as well as emerging signs of broad-based recovery. As we are now midway through our fiscal year, and with the backdrop of improving end markets, while noting that uncertainties due to the pandemic continue to exist, full year guidance has been provided for fiscal 2021. We expect adjusted operating margin to increase in fiscal 2021 driven by expanded leverage on higher volumes partially offset by higher commodity costs and mix pressures. I am proud of the hard work and dedication our employees have shown during this unprecedented time of uncertainty. We remain committed to our customers as we advance filtration for a cleaner world.”

Second quarter 2021 Engine Products (Engine) sales increased 6.2%, reflecting strong results in Off-Road and Aftermarket, partially offset by continued weakness in Aerospace and Defense and On-Road. The decline in Aerospace and Defense was primarily due to lower levels of demand in commercial aerospace as a result of the ongoing COVID-19 pandemic. Engine segment sales across the Asia Pacific region experienced year-over-year growth where both Off-Road and Aftermarket sales were up significantly. On-Road sales declined modestly driven primarily by weaker U.S. Class 8 truck builds.

Second quarter 2021 Industrial Products (Industrial) sales declined 4.3%, driven primarily by continued softness in Industrial Filtration Solutions (IFS) due to lower demand for dust collection products as customers remain cautious in making capital investments. China continues to be a positive for IFS as market share gains, coupled with recovery from the COVID-19 pandemic, drove double-digit growth in the country. Process Filtration sales expanded globally driven by market share gains. Gas Turbine Systems’ sales decline was due to lower project sales, and sales in Special Applications remain under pressure from lower sales of disk drive filters.

Veolia Water Technologies to supply systems for reuse of 40,000 m3 of water per day in Kuwait

Veolia Water Technologies Gulf was awarded a contract by Mohammed Abdulmohsin Al-Kharafi & Sons (Al-Kharafi) to supply, supervise, install and commission 53 AnoxKaldnes Moving Bed Biofilm Reactor (MBBR) packaged sewage treatment plants. This order is the largest ever received by Veolia for this type of packaged plants and will allow for 40,000 m3 of water to be reused each day in water-scarce Kuwait.

The compact and packaged sewage treatment units will be installed at various locations throughout the country where they will compensate a shortage in sewage handling. A major advantage of these smaller, packaged units when compared to one big wastewater treatment plant is that the size of the network is vastly reduced as it is possible to spread the units in various parts of the housing development or city.

Following treatment, the effluents will be reused for irrigation, therefore saving freshwater that would otherwise have been desalinated at high cost, particularly in terms of energy.

In Sabah Al Ahmad City, a planned community located 80 kilometres south of Kuwait City in Khiran Kuwait, 23 AnoxKaldnes MBBR package plants with a total treatment capacity of 17,000 m3/day will be added to existing sewage treatment installations. In West Abdullah City, new sewage treatment installations will be built and will include 27 package plants totalling 23,000 m3/day. Finally, three more units will be installed as provisional items at other locations.

Veolia Water Technologies will also supply pretreatment and UV disinfection as well as proprietary Veolia technologies Multiflo for clarification and Hydrotech Drumfilters for tertiary treatment. Veolia’s digital solution Hubgrade will also be provided to support the operational teams in their daily monitoring with a proactive, data-driven service and remote reporting.


Grolsch running pilot with NX Filtration nanofiltration technology at its brewery in Enschede, Netherlands

The renowned Grolsch brewery in Enschede, the Netherlands, has partnered with NX Filtration, a membrane manufacturer also headquartered in Enschede, to launch a full-scale water treatment pilot. With the results from this pilot Grolsch will compare NX’s dNF membrane technology with conventional water treatment solutions on important factors such as the retention of micropollutants and hardness, energy usage and the need for cleaning agents.

Grolsch has a long history of improving reliability and robustness of its processes and minimizing impact on the environment. At its location in the eastern part of the Netherlands, where summer droughts have become longer and more severe over the years, ground water levels are declining. To assure that, despite these regional challenges, the well water that is used for brewing its beer will remain at the highest standards, Grolsch is now investigating NX Filtration nanofiltration membranes as a more sustainable option to its current treatment methods.

INDA adds webinar program to discuss new ASTM facemask standard for the general public

INDA, the Association of the Nonwoven Fabrics Industry, has added a date to its upcoming webinar series, Tuesday, March 2, 11 am EST, to discuss the new ASTM F3502-21 Standard Specification for Barrier Face Coverings, which was introduced by ASTM on February 15. This standard establishes a set of test methods that evaluate the filter, fit and leakage performance of barrier face coverings, commonly referred to as “facemasks,” worn by the general public and not to be confused with respirators nor medical or surgical masks.  The webinar will be presented by respiratory expert, Jeff Stull, Vice Chair of the ASTM Committee that wrote the standard, and Dave Rousse, INDA President.  It will provide a detailed review of the new ASTM standard and the test methods it entails and the impact on the entire supply chain of facemask production.

The purpose of guidance for the general public to wear facemasks is to control the spread of viruses. Facemasks made to this new ASTM standard will also provide a degree of particulate filtration to reduce the amount of inhaled particulate matter.

“We approached NIOSH last year on developing a general public facemask standard that could use nonwoven materials beyond Meltblown that still deliver an effective level of filtration, as there was so much demand for the N95 respirators and masks once the Asian supply chain was cut off,” said Dave Rousse, INDA President.  “We were delighted to get a positive response from Jon Szalajda, NIOSH Deputy Director, National Personal Protective Technology Laboratory, who is also the Chair of the ASTM Committee dealing with standards in this area.”

“This was a worthwhile project that we worked through the ASTM process in record time,” said Szalajda.  “It should provide an important benefit in the fight against COVID-19 spread by reducing consumer confusion about what works and what does not and assisting manufacturers in making effective products.”

The goal of the standard is to assist consumers in making informed decisions about facemasks given the vast array of products currently for sale, including various patterns promoted for home-made manufacture using common textile materials.  Prior to the ASTM standard, no standard test method existed which allowed comparisons among different products nor were there any minimum performance requirements.  This new standard provides these performance requirements as well as a set of specifications, guidelines and expectations for facemask manufacturers and media suppliers.

The Mar. 2 webinar will be in addition to the INDA Webinar Series already scheduled for March 16, March 25 and April 6. For information on the full webinar series, visit

Research shows sorry state of air quality in U.S. subway systems

As reported by The Guardian, People traveling on subway systems in major U.S. cities are being exposed to unsafe amounts of air pollution, with commuters in New York and New Jersey subjected to the highest levels of pollution, research has found.

Tiny airborne particles, probably thrown up by train brakes or the friction between train wheels and rails, are rife in the 71 underground stations sampled by researchers during morning and evening rush hours in Boston, New York City, Philadelphia and Washington DC, the cities that contain the bulk of subway systems in the US.

The levels of these tiny specks of pollution, called PM2.5, were well above nationally determined safe daily levels of 35 micrograms per cubic meter in each of the cities. New York’s Metropolitan Transit Authority (MTA) system had 251 micrograms per cubic meter, followed by Washington DC with 145 micrograms per cubic meter. Philadelphia was, comparatively, the cleanest system but still breached the limit beyond which serious health hazards are risked.

NX Filtration supplies its nanofiltration membranes to Forsmark power plant in Sweden

For the local production of drinking and process water for the Forsmark power plant in Sweden, ProMinent, a multinational water treatment systems supplier, installed a water treatment system based on hollow fiber nanofiltration membranes of NX Filtration.

The feed water is taken from a local, highly colored lake with temperatures close to zero degrees Celsius in the winter. This feed water goes through a simple one step process consisting of, initially, 74 dNF40 hollow fiber nanofiltration modules of NX Filtration. This system removes bacteria, viruses and organics, including color, from the lake water. The resulting product water is used for drinking water and for process water in the Forsmark power plant.

Compared to the existing system, which is based on coagulant injection, dissolved air flotation and sand filtration, the new nanofiltration setup offers various benefits, such as better removal of organics, micropollutants and other contaminations. It also avoids the use of chemicals in pretreatment and it reduces the number of process steps, which also results in a smaller physical footprint of the system.


Metso Outotec to reorganize its Sweden operations

Metso Outotec, a combination of Metso Minerals and Outotec on June 30, 2020, specializing in end-to-end solutions and services for the minerals processing, aggregates and metals refining industries globally, has convened local trade unions to negotiations concerning the restructuring and operational reduction of its operations in Sweden. The measures relate to new product strategy and business model changes and synergy targets from the Metso Outotec merger.

The Swedish operations have issued a negotiation proposal, according to which the total reduction need in Sweden is approximately 80 white collar positions mainly in the Minerals, Metals and Services business areas in the Skellefteå and Sala locations. Other locations may be impacted to a small extent.


Oerlikon Nonwoven, Wolf PVG commission meltblown plant for FFP2 masks

Oerlikon Nonwoven has commissioned a double-beam meltblown plant with ecuTEC+ electro charging unit at Wolf PVG GmbH & Co. KG. With this plant, the East Westphalian company can now provide nonwovens for the production of surgical and FFP2 masks. In addition to this filter material, which is in great demand today, high-quality meltblown nonwovens can also be produced for medical and industrial filter applications. The plant has now been running for several weeks under stable production conditions with optimal nonwoven fabric quality of the highest standards.

With the beginning of the COVID-19 pandemic and the shortage of protective masks that ensued, Wolf PVG GmbH & Co. KG, a wholly owned subsidiary of the Melitta Group, switched part of its production capacities to nonwoven mask fabric production. As a highly specialized system supplier for everything to do with vacuum cleaners and industrial filter technology, the company from East Westphalia can fall back on its extensive know-how and many years of experience.
