Membrion secures DOE grant for novel manufacturing of desalination membranes

Seattle-based membrane startup Membrion has received a US$1.1 million grant from the United States Department of Energy (DOE), Advanced Manufacturing Office (AMO), through the Small Business Innovation Research (SBIR) program.

The Phase II Award will support a two-year project to develop, implement, and optimize a machine vision system to provide real time analytics of Membrion’s roll-to-roll ceramic desalination membrane production line.

A critical component of the DOE’s Water Security Grand Challenge is to address water security and alleviate water stress. Over the next ten years, nearly every US state will experience a water shortage, caused by climate-driven water shortages and dramatic increases in the demand for clean water. Membrion is on a mission to recycle water that was previously too challenging to reuse, using silica to create ceramic desalination membranes.

ZwitterCo raises $33M for wastewater filter tech

ZwitterCo, a wastewater filter membrane manufacturer, announced it raised $33 million in Series A funding led by DCVC. The Boston-based company plans to use its new funds to expand the development and production of its zwitterionic membrane product.

The jar in the middle is the concentrate of waste that has been pulled out of the water with the filtration system and can be used in to make other products, like fertilizer of feestock, which can be sold.

ZwitterCo’s technology is a rugged polymeric membrane used for wastewater purification. The membrane is reportedly immune to “irreversible fouling,” unlike other water cleaning cycle membranes that degrade over time and need to be replaced. According to the company, its membranes perform as if they are new following each cleaning cycle, saving wastewater plants time and money in membrane replacement.

The ZwitterCo membrane is made of zwitterion, a special class of hydrophilic molecules that are highly attractive to water. The membrane uses patented zwitterionic copolymers that can self-assemble into hydrophilic channels, which let water pass through but trap anything else. 

ZwitterCo’s technology can be used in a variety of applications and can repel thousands of times more organic compounds than traditional filters, according to the company. Currently, the company is working on building its suite of products and expanding its technological capabilities.

Ohio Fabricators grows business, announces new products

Ohio Fabricators Company (OFCO), a leading manufacturer of stock and custom strainers, breathers, diffusers and screen assemblies for the filtration and fluid power industries, is reporting strong results despite many challenges in the overall business environment.

According to OFCO Chief Executive Officer Mike Shaw “we’ve been able to build our inventory of parts, during these tough times, allowing us to deliver finished products from our Coshocton, Ohio facility much faster than our competitors, while reducing our dependence on foreign-manufactured components.”

Sales Manager Mike Smith said, “we have two new products that we’ve had in development for a while.” These include our OS line of giant suction strainers with diameters up to 8.1” and flow rates up to 400 GPM. The other product is a screen developed specifically for the insect control business. Smith says that the first run of this product has already sold out with many more customers interested in it.

The OS strainer line is targeted to heavy industrial users such as oil and gas, steel production and pulp and paper mills. Oil and gas industries employ power units that push up to 400 gallons per minute (GPM) through their systems while the steel industry has equipment requiring up to 800 GPM flow rates. OFCO’s OS line is perfect for these applications.

NAFA announces 77 Clean Air Award Recipients for 2022

The National Air Filtration Association has announced its recipients of the Clean Air Awards for 2022. The Clean Air Award is presented each year to the building owners and managers who take steps to significantly improve the quality of their indoor air by increasing the level or efficiency of their HVAC air filtration system in 10 specific categories.

NAFA’s Executive Director, Emily Bardach, CAE, congratulated the award winners by saying, “The 2022 Clean Air Award program received an unprecedented number of submissions this year. The past few years have been a challenge for our members and their clients. Responding to the need for stricter indoor air quality specifications, the nominated facilities have all increased the level of indoor air cleanliness with filtration and improved system hygiene.”

Candidates are nominated for the award by NAFA members and must submit detailed and specific steps taken toward cleaning the indoor environment through “best air filtration practices” and system hygiene. A NAFA Certified Air Filter Specialist confirms these improvements. Nominees are judged by the NAFA Clean Air Award Committee, and each recipient receives a custom-designed award, building signage and recognition for their efforts.

Award-winning buildings must maintain IAQ diligence and submit inspection data each year to maintain the NAFA Clean Air Award.

Germany’s Hengst Filtration is acquiring Linter Group, a Brazilian company that manufactures air filters and air filtration equipment. Linter has been supplying the South American market with filtration solutions since 1995 and employs around 100 people and is based in São Paulo. Linter products can be found in the food industry, in laboratory and pharmaceutical facilities and in commercial air conditioning and ventilation technology.

“With this acquisition, we not only underline our claim to leadership in industrial filtration, but can also further expand and strengthen our vision “purifying our planet” in the South American market with the filter applications of the Linter Group,” said Christopher Heine, CEO of Hengst SE. “Linter has impressed us with its strong growth in recent years and we are pleased to be able to acquire one of the three leading companies in the field of industrial air filtration in Brazil for the Hengst Group.”

Hengst has been operating in Brazil for over 20 years with a sales office in São Paulo and a production site in Joinville.

The Linter acquisition is expected to close in the fourth quarter 2022. The owners will remain with the company after the sale and will closely accompany the integration of Linter into the Hengst Group.
Hengst continues to focus on growth and the expansion in filtration solutions for industrial and indoor air applications, having acquired Nordic Air Filtration in 2016, Delbag in 2018 and the hydraulic filtration business of Bosch Rexroth last year.

LG Electronics (LG) is presenting its new air purifier, the PuriCare Objet Collection Aero Furniture, at IFA 2022. The follow up to the acclaimed PuriCare AeroTower revealed at CES earlier this year, the new table-type model blurs the line between beautiful furniture and advanced air purifier, offering a design that can be tailored to meet individual preferences, 360-degree air purification, and user-friendly features.
The compact LG Aero Furniture has a relatively small size that makes it perfect for smaller spaces, such as a single bedroom, study or studio, while users can choose the color of the unit’s base (Crème Rose, Crème Yellow to Crème Grey) and the shape of its table-top (Round or Track) to suit their personal tastes or match their home décor.

LG table-type air purifier

The smooth upper surface of LG’s innovative, new product provides a useful place for storing household items or displaying decorative objects. It also integrates convenient controls on its underside for powering the device on/off, and for managing its airflow modes and mood lighting features. Subtly positioned near the edge of the table-top, and flush with its surface, is a series of small indicators denoting Wi-Fi connectivity, air quality, air flow strength and upgrade status.

What’s more, the new Aero Furniture presents an array of thoughtful features for a more personalized user experience. Users can conveniently charge their smartphones and wireless earbuds via the table-top’s built-in wireless charger and create a pleasing atmosphere with the mood lighting feature. Providing eight different colors to choose from, Aero Furniture’s mood lighting can be easily controlled using the LG ThinQ app. Furthermore, LG’s unique air purifier is designed with sustainability in mind, incorporating components fabricated from reusable plastic harvested from old appliances and electronics products, and shipping in packaging made from reusable materials.
