BYU students create new water filtration device for Pakistan
Working in Provo, Utah, a group of BYU engineering students created a new filtration device that is helping thousands of people across the world in Pakistan have access to cleaner, safer drinking water.
Elder Peter F. Meurs, a General Authority Seventy, was the lead manager for the water filtration project as he was serving as first counselor in the Asia Area Presidency.
“In talking to government leaders about the highest humanitarian priorities, leader after leader identified clean water as a very significant priority for the country,” Elder Meurs said in a BYU News release.
About 30% of diseases in Pakistan come from contaminated water — but those diseases are preventable.
Owen Tolley, a student on the BYU team, said they thought a lot about what they wanted to be able to fix like turbidity, coliforms including e coli, and arsenic — which is known to be found in high levels in certain regions.
“We thought a lot about what methods would 1) be most effective at treating the water 2) be robust and simple to use and maintain 3) be economical,” Tolley wrote in an email to the Church News.
They came up with a device that takes water through both microfiltration and ultrafiltration. Team member Bethany Parkinson said they took it to the duck pond south of BYU campus.
No more harmful bacteria remained in the BYU Botany Pond water. Tolley said the prototype gave them an idea of what was possible, and then they connected with a Pakistani company that was able to build and maintain the systems at a reasonable cost.
Elder Meurs ordered 15 water treatment devices, which were implemented immediately in the Asian country.
Homemade air purifiers that trap COVID-19
A group of students from the University of Connecticut along with team members at UConn Health in Farmington built an air purifier out of furnace filters, a fan and tape. It’s called the Corsi-Rosenthal box, and it traps the COVID-19 virus inside.
“It captures fine particular matter in the air about as fine as a commercial filter,” said Marina Creed, APRN of UConn Health’s MS Center.
“We’ve found these are incredibly effective at lowering the levels of particles and these particles transmit infectious diseases like COVID and the flu in classrooms,” said Dr. Kristina Wagstrom from the UConn School of Engineering.
Creed and Dr. Wagstrom rallied experts from UConn Health and UConn in Storrs to recreate the Corsi-Rosenthal box.
Research shows it traps upwards of 90% of small particles from inside a room.
At around just $60 to make, hundreds of the boxes are in local schools like in Coventry and West Hartford, and even the White House.
With the success they’re seeing in classrooms, the goal is to get more of these homemade air purifiers throughout the state to help keep COVID numbers low.
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.
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.
