Johnson Screens, a brand of Aqseptence Group, is the leading global provider of screening and auxiliary solutions. We are the inventors of vee-shaped Vee-Wire® wedge wire screens, which are used to create the most diverse filtration media with great strength, long service life, and a uniquely high level of adaptability for high-efficiency liquid/solid separation. With 120 years of experience providing innovative screening solutions in more than 100 countries around the world, almost every product and object around you has touched one of our screens.
We are present on every continent, and our facilities in Brisbane, Australia, and Ahmedabad, India, handle direct support for the Philippine and Southeast Asian markets.
Our location in Australia has enjoyed over 70 years of operations, with the new facility boasting a footprint of over 4,500 m2 and a workforce of 140 employees. Working with experts from the other brands of the Aqseptence Group, Johnson Screens Australia has supported many industries in Oceania by providing solutions for water wells, food & beverage, mining, energy & chemical processing, industrial & municipal water/wastewater treatment, and architectural applications. In addition, our Australian location relies on applying emerging and cutting-edge manufacturing technologies and strategic partnerships. For example, the company partnered with the global printing firm HP to explore the possibilities of leveraging additive manufacturing processes and 3D printing technologies to fabricate components of Johnson Screens solutions.
Meanwhile, our Indian facility has over 20,000 m2 of manufacturing space, soon to be augmented with an additional 11,000 m2 expansion and many new positions to support the existing workforce of more than 250 workers. Besides providing capacity to our regional and global manufacturing, Johnson Screens India fulfils our vision of protecting lives and our precious natural resources by providing key products and solutions for government and private projects to supply clean water to large populations and improve their quality of life.
Johnson Screens Water Well Solutions
Johnson Screens has been a leader in the water well industry since the company’s inception in 1904. Our continuous-slot profile wire technology and Vee-Wire well screens revolutionized the water wells industry and quickly became the industry standard around the world. Johnson Screens’ experts led the development of the industry by creating innovative solutions and became a reference with the publication of our Groundwater and Wells book in 1966. After three editions, that book continues to be a staple of water wells education. Today, we are recognized as the complete solutions provider for water wells with an extensive portfolio of well screens, casing, pump pipe and accessories in stainless steel and PVC, and well treatment chemicals and filter packs.
Our Vee-Wire technology was further developed and improved over the years, and it still today ensures high open areas to flow, optimal performance, and resistance to plugging as seen in the large Stainless Steel Screens portfolio. Available in 304 and 316 stainless steel and a wide range of specialty materials, our stainless-steel well screens are suitable for usual and the most demanding applications.
Some examples of demanding applications where the robustness of our products is fundamental are Managed Aquifer Recharge (MAR) and Aquifer Storage and Recovery (ASR) wells. The components of those wells are submitted to hash conditions or taken to their limits, which requires comprehensive solutions to provide reliable wells while balancing expenses. By combining the tradition and knowledge with which we have led the water wells industry for 120 years with innovative equipment specially designed for these applications, Johnson Screens provides complete solutions for MAR and ASR wells. Those solutions are supported by technical and construction experience in some of the most demanding projects in the world and the most reliable water well equipment in the industry.
Some products used in those applications, which are also suitable for mining water and dewatering wells, are the Shur-Pak™ Glass Bead Filter Pack and the Muni-Pak™ Pre-Packed Screens. Easier to install than traditional filter packs, our Shur-Pak glass beads for filter packs are stronger, chemically inert, and are almost perfect spheres – virtually eliminating bridging during installation that can be an issue in traditional filter packs.
Meanwhile, Muni-Pak offer a unique solution that combines the advantages of pre-pack screens and glass filter packs for mining applications. Using Shur-Pak glass beads as the filter media reduces the likelihood of filter pack damage by biofilm and encrustation, lowering overall well-maintenance costs. Additionally, Muni-Pak’s dual-screen construction is four times stronger than standard rod-based screens, and filter pack placement is not required, reducing costs and enhancing well efficiency. By eliminating the need for a larger borehole, the Muni-Pak shortens the time required to drill a well, and accelerates overall development time.
Johnson Screens Complete Screening Solutions for Mining
Johnson Screens has innovative screening solutions for mineral processing applications. With a century of design innovation, industry experience, and technological know-how behind the brand, Johnson Screens has the in-house capabilities to optimize your mineral beneficiation processes.
Our mining screen systems are simple, resilient, and effective. Our products’ design maximizes production yield and maintenance efficiency. Our panel designs include a variety of aperture and fixing systems, available in Vee-Wire, polyurethane, perforated plate, and/or rubber. Our global network of sales personnel and process engineers with vast mining experience supports all our products and services.
The dewatering capability of a screen is determined by the percentage of open area. Our screens have the capability to provide up to 50% more open area, because of our greater range of narrower wire profiles. The wires can be as narrow as 0.5 mm (0.020 in.) and up in 0.25 mm (0.010 in.) increments. With increasing mine site safety awareness, Johnson Screens has developed an innovative split sieve concept for our Sieve Bend Screens. This concept affords easier handling of the larger width sieve bends, particularly those 1500 mm (59.06 in) and over. This is a major benefit because of the reduced size and weight of the screens.
Additionally, Johnson Screens offers a comprehensive range of Polyurethane Screening Systems that provide value every day in the processing of coal, iron ore, gold, phosphate, copper, lead and zinc, bauxite, sand and gravel and many other minerals. Our polyurethane panels have the ability to incorporate other surface media with the lateral engaging clip design. The ability to combine differing materials and modules allows for plant managers to manage the screen as desired. This “configured deck” concept is another way Johnson Screens can help get the most out of any operation.
Our ability to offer a variety of wire shapes and configurations make it possible for our engineers to design the most efficient screen for any industry, including those of precious mineral mining. Johnson Screens’ stainless steel CIP/CIL Interstage Screens are used to recover mined ore in the slurry separation process. For additional support for particle separation and classification, we also offer Elution Column Screens and Drain and Septa Screens. All screens are designed to meet each customer’s specification for open area, flow, and loads.
Lastly, Johnson Screens offers a wide array of scalable intratank screens that are compatible with resin exchange processing including Header Lateral Systems, Support Grids, Distributor Trays, Scale Traps, Outlet Baskets, and more.
