The Contra-Shear Next Generation is Here! 

Melbourne, July 25th, 2023 - Following its predecessor’s tradition and long track record, the Contra-Shear Next Generation is here at last! With this design, Johnson Screens is proud to offer improved features and innovations that will assist every user in realizing their environmental sustainability goals.  

 “There were several goals in mind when designing the Contra-Shear Next Generation“, says Denys Visser, Global Research and Product Manager for Johnson Screens. “Our main focus was to increase solids dewatering and capture rate provided by the previous generation’s equipment. That expands the range of applications for the Contra-Shear Next Generation and makes it the ideal liquid-solid separation solution for many industries.”  

 As with the traditional Contra-Shear, the self-cleaning, internally fed rotary fine screen relies on the shear force effect created by the drum rotation to enhance the separation of solids from the effluent. Screened effluent passes through the Vee-Wire® slots into a tank from which it is pumped for further processing. Solids in the dewatering zone amalgamate and are continuously rolled thanks to the rotation of the screen drum, resulting in further reduction of liquid content.  

“We incorporated solutions to enhance the quality of the processes while reducing operating costs,” says Denys. The new design includes an external rack and pinion drive mounted on the clean side of the screen, leaving no impurities on drive elements and good accessibility during maintenance. No chains, sprockets, oilers, or other wearing parts or lubrication are required. An angled frame rail prevents the settling of solids/liquids inside the machine by removing flat surfaces. “That remarkably improves process hygiene by reducing contamination risk.” Lastly, Denys adds, “the redesigned trommel support wheels allow replacement in situ without drum removal or lifting, which significantly simplifies maintenance by reducing the associated labour and downtime costs.” 

 Maximizing process control and efficiency was another guideline while designing the Contra-Shear Next Generation. The addition of clear side view hatches enables direct process observation and improves process visibility. Johnson Screens’ knowledge of Contra-Shear technology also allows our specialists to accomplish the same level of dewatering as the previous generation Contra-Shear with fewer and/or smaller Next Generation models.  

The Contra-Shear Next Generation is available in 304 & 316 stainless steel and provides efficient solids separation, thickening, and dewatering!

Johnson Screens Takes the Lead in Chlorine Alternatives 

New Brighton, June 15, 2023 – Johnson Screens is proud to announce an addition to the Nu-well® well cleaning and development chemical family, a staple of our historic Water Well division. How could this product line get any stronger? With Chlor-Safe, a safe and effective alternative to traditional chlorine (bleach) for disinfecting water wells. 

Like all Nu-Well products used within the well, Chlor-Safe NW-420 is NSF-certified for potable water use (certified by NSF to NSF/ANSI/CAN 60.) Used to disinfect wells without needing pH control, this dry, granular product is simple and has a long shelf life. Chlor-Safe is added to a water container at the surface and dissolved before disbursing to the entire well. This ensures that the chemical is in solution before putting it downhole, allowing the Chlor-Safe to combat bacteria throughout the entire well effectively. 

“We developed Chlor-Safe to dissolve faster than SterileneTM and other chlorine products, so it activates sooner when disinfecting wells and removing bacteria and other contaminating organisms, such as coliform, iron bacteria, E. coli, and other bacteria that cause that tiresome rotten egg smell.”, says Wayne Meyer, Product Manager for Johnson Screens’ Water Wells Business Unit. “Chlor-Safe can also be used to treat near wellbore damage and reduce congestion caused by clays or residual drilling mud.”, he adds. 

 Chlor-Safe is available now through our outstanding network of water well distributors. As with all of our Nu-Well products, please use and dispose of Chlor-Safe NW-420 in accordance with local rules, regulations, and ordinances.

Ahmedabad, February 2023 – India, home to 18% of the global human population and 15% of the worldwide livestock population, only commands 2% and 4% of global land mass and freshwater resources, respectively. With a growing population and expanding economic influence, there is a consequent increase in demand for water in various sectors (agriculture, industry, domestic, recreation, infrastructure development, etc.) While India does control a substantial amount of the global extracted groundwater supply (25%), the demand-supply gap is compounded by such challenges as overextraction, poor recharge, and low storage capacity, among several other factors.

In response to this growing demand for rural access to fresh water, the Indian government launched the Jal Jeevan Mission in 2020 to provide Functional Household Tap Connection (FHTC) to every rural household by 2024. The program aims to deliver water supply in adequate quantity and quality regularly at a household level by installing water wells in nearly 100,000 villages around the country. Source sustainability measures set by the mission also require an equal number of dedicated recharging wells set around the country.

True to our vision of a world where protecting lives and our precious natural resources comes first and to our mission of supporting our customers on their journey to environmental sustainability, Johnson Screens is a main contributor to the success of the Jal Jeevan Mission. Thanks to the outstanding quality of our Vee-Wire screens used the world over in groundwater and well industries, superior production capacity compared to competitors, and our unique position within the Indian water wells market as the sole possessors of an in-house nationally accredited testing facility, Johnson Screens India was able to secure the rights to supply the screens for the vast majority of the contracts associated with this project.

“We are very proud to be part of the important project for the people in India”, says Johnson Screens Private Ltd. CEO Shiven Amin. “This project allows us to fulfil our role in providing people access to clean water and improving their daily lives globally.”

Johnson Screens introduces a new family of splined anti-rotational drop pipes.

Las Vegas, December 7, 2022 – Johnson Screens is happy to announce the JSL Family of splined anti-rotational drop pipes launch at the National Groundwater Association (NGWA) Groundwater Week 2022. 

Based on the original design, the JSL Family of drop pipes brings new configurations and materials that cover a broad range of drop pipe needs. The first two members of this product line are the new JSL Standard stainless steel drop pipe, and the JSL Deep Stainless Steel drop pipe for Extreme Applications. 

“The new JSL Standard stainless steel drop pipe comes from improvements on the original splined connection design”, says Wayne Meyer, Product Manager for Johnson Screens’ Water Well Business Unit. “It utilizes a nylon spline which allows for a reduction in size and weight on the fittings. That provides our customers with a more cost-effective solution for normal applications.”  

“The JSL Deep drop pipe has been crafted for the most demanding applications and is the best choice when it comes to installing extremely deep wells due to its high tensile strength”, adds Wayne.  

In both the JSL Standard and the JSL Deep drop pipes, a stud neutralizes the twisting forces on pump startup and shutdown on the male end, which engages in a notch on the female end. In addition to preventing torque rotation, This enables a single-button spline connection that requires no tools for assembly and disassembly and reduces pump running time. 

The new JSL Family of drop pipes will continue to expand with the upcoming addition of products in different materials and designs.

A partnership between Johnson Screens and Mounds View Public Schools helps students prepare for manufacturing careers.

How do we help high school students answer the question – “what’s next?”

Transitioning from high school to life’s next chapter can take many different forms. Some students might want to attend college, others might opt to seek a job around graduation, and others might still be more interested in learning trades or technical skills. In Mounds View Public Schools, the preparation necessary to make this transition is often provided through Career and Technical Education (CTE) courses.

Before graduating, students enrolled in CTE courses are offered an opportunity to explore career options, earn college credit, and in some cases, work towards completing career or technical programs. Today, over 1,000 Irondale and Mounds View students are participating in CTE courses ranging from accounting and automotive education to fashion design and engineering and everything in between. Community partnerships play a huge role in the success of these courses, and today the school district is partnered with 40 local organizations to bring real-world experience to students.

Johnson Screens is proud to be among these partner organizations, and presently we are thrilled to be hosting four Irondale students learning welding at our New Brighton facility.

“Students bring us instant value,” says Dewey Josephson, Johnson Screens’ Operations Manager. “Within a couple of weeks to a month, they’ve passed all the training and certifications for the welding, and they are able to do production welding.” For our organization and the students learning our trade, it’s been a mutually enjoyable experience. “I really like CTE classes,” said Area Learning Center senior Ryan Larson (pictured). “They help us get an OSHA 10 certification very soon in life, so going into the trades, I have a little bit more knowledge than other kids coming in. It really opens up doors for better job opportunities.”

Historically, preparing students for the jump to college has been a point of emphasis for many school systems and their curricula. While this is certainly important, it can leave students for whom college does not seem like the right next step without proper guidance on how to make the transition to their desired career path post-graduation.

“Graduating seniors are often asked, ‘What college are you going to?’” says Chris Lennox, superintendent for the Mounds View Public School District. “We’re shifting that narrative to “What is it you want to be, and how can we help you on the pathway to whatever that is?’”

Johnson Screens is honoured to participate in this wonderful opportunity to provide students with work experience to help prepare them for their future. We couldn’t be happier with our student welders!

Johnson Screens and HP use innovation and cutting-edge technology to innovate and optimize screen manufacturing.

Brisbane, November 12, 2022 – Relentless innovation to serve the status quo. It’s a sentence that, at face value, seems to contradict itself, but it’s one that Johnson Screens has lived by for nearly 120 years. Our core Vee-Wire® product, while revolutionary at the time of its invention, has remained relatively unchanged since its introduction. Yet through sheer inventiveness, we have found an ever-growing list of successful applications for our screens. But what if we were to take this innovation a step further? What if we were to rethink how our core product is made?

These are exactly the questions that Denys Visser and his team are exploring with their recent experiments with additive technology and 3D printing techniques. The goal with our products, as with many manufacturing firms, is to create the most utility while using the least material possible. Given that, by definition, additive fabrication uses the smallest necessary amount of material to complete a given design, this process’s synergy in combination with our screens is truly extraordinary.

“For a long time, we’d been very interested in additive,” says Denys, Global Research and Product Manager for Johnson Screens’ Australia division. “However, additive never really left the hobby zone for us. The reason why I say that is, while the technology was able, the process around it was not… The other part of that was material. When you’re working with liquids or water, you can’t have a material that absorbs. The easiest material that many people use is something like nylon that is actually strong… (However), you go towards nylon, which absorbs water; we can’t use it.”

In search of a strong, non-absorbent fabrication material, Denys and his team settled on polypropylene, a cost-effective yet resilient material favoured by many 3D printers. An initial test was conducted using additive-derived components purchased from Weerg in place of the traditional stainless steel screens. After nine months, Denys found that the new components outperformed the original ones. Seeking to capitalize on the success of this new fabrication process, Johnson Screens began looking for a 3D printing partner that could keep up with the unique demands of the wastewater treatment industries we serve.

“Wastewater treatment plants are not allowed to stop. Ever. You cannot have breaks in service when it comes to wastewater; they have to run because the alternative is too bad for cities to handle,” says Denys. To properly service wastewater treatment equipment, parts must be fabricated quickly and continually. This meant our 3D printing partner needed to have not only to proper technology in place to fabricate our parts using polypropylene but the systems in place to meet this demand as well. Enter HP 3D Printing.

With over 76 years of technological innovation under their belt, HP mirrors the inventive spirit on which we pride ourselves at Johnson Screens. In a short time, our organization has been able to leverage HP 3D Printing products; our efforts have been met with surprise and praise.

“I always enjoy showing these parts to our suppliers or client-side engineers and asking them to figure out how they were made because as soon as you know a little bit about plastics, you look at the parts and say, ‘it’s impossible to injection mould, there are too many parallel walls.’ Some of them can guess right away, and they look at me and go, ‘is this additive?’”

The additive-derived components we’ve collaborated on have suffered zero recorded failures in testing and limited commercial use. Some of Johnson Screen’s customers have even begun to specifically request that they receive the new parts instead of the usual stainless steel screens. Johnson Screens is proud to partner with fellow technological pioneer HP 3D Printing, and we look forward to continued success for both of our organizations in the coming days.

By implementing the utilization of solar energy and other green initiatives, Johnson Screens India contributes to the creation of a sustainable future.

Ahmedabad, August 1, 2022 – Johnson Screens announced today a successful installation of a solar power plant on the roof of their manufacturing facility in Ahmedabad, India.

“A few years back, we were looking at our electricity consumption,” says Shiven Amin, CEO of Johnson Screens (India) Pvt. Ltd..“We began the exercise by talking with some companies about our ability to harness renewable energies around us, solar being the most accessible. We ended up installing a 150 kW solar power plant. The project was completed within three months and went off without a hitch. When we first considered solar, we had restrictions limiting our installation to cover approximately 50% of our facility’s monthly consumption. However, if those restrictions are lifted in the future, we can increase this capacity. That is a fantastic step towards increasing our utilization of renewable energy and meeting our sustainability goals.”

In addition to the solar panel installation, there are a number of other green initiatives mandated by the government with which our facility is proud to be fully compliant. Among these programs are “zero liquid discharge” programs, rainwater collection and recharging efforts, and tree planting programs. “For every 100 square meters of property, one tree must be planted as a green zone. We followed that rule AND made it a part of our culture. Visitors from other Johnson Screens locations plant their tree when they come to our facility,” says Amin. “Those initiatives demonstrate Johnson Screens’ commitment to a responsible and sustainable future.”
