History of Filtering Systems

Filtration systems have roots stretching back to ancient civilizations like those of the Egyptians and the people of ancient India. Hieroglyphs discovered in the tombs of Ramses II and Amenophis II illustrate the Egyptians’ use of sand to filter drinking water. Sand was selected for its ability to capture and settle suspended particles, ensuring cleaner water. Similarly, ancient texts in Egyptian and Sanskrit, including the Sushruta Samhita, reveal various water purification techniques employed at the time, such as sun-heating, boiling, and filtering through gravel.

In the ancient world, Greece was home to another significant society that engaged in early forms of filtration. Around 500 BC, the Classical Greek physician Hippocrates pioneered the invention of the first bag filter or sieve. This device, now known as the Hippocratic Sleeve, was essentially a cloth bag through which he poured boiled water. By using this filtration method, he successfully removed sediments that could cause unpleasant odors or tastes in the water. Hippocrates utilized this filtered water as bathwater for his ailing patients, enhancing their comfort and hygiene.

Filtration System – Precision Filtration Products

From Antiquity until the Industrial Revolution, filtration technology in Europe saw minimal evolution. However, during the 8th century in the Middle East, an Arabian alchemist named Gerber revolutionized water purification with innovative techniques. He developed new methods that utilized stills linked by wick siphons, which purified water as it transferred from one still to another.

Once the Dark Ages had ended, scientists resumed their exploration of filtration systems. In the 1500s, they developed the first air filtration systems, which served as early respirators.

In 1627, Sir Francis Bacon, an English philosopher and scientist, began experimenting with methods to desalinate saltwater, attempting to use sand in his process. Though Bacon’s efforts did not succeed, his pioneering work ignited a wave of interest in water research. By the 1670s, scientists Robert Hooke and Antonie van Leeuwenhoek advanced the development of the microscope, allowing them to observe microscopic pathogens in water. This crucial discovery highlighted the necessity of effective water filtration, setting the stage for future advancements in the field.

During this period, a significant breakthrough in filtration was the discovery of reverse osmosis. While Jean-Antoine Nollet first observed this phenomenon in 1748, it wasn’t until the mid-20th century that scientists began applying it to filtration processes.

In the 19th century, numerous scientists achieved significant advancements in filtration technology. In 1804, John Gibb, a Scotsman from Paisley, pioneered the use of sand filtration to purify and market water. Around the same period, ceramic filters began to be widely used for water purification. By 1830, London had inaugurated its first water treatment plant.

Early air filters were quite basic and didn’t gain widespread popularity until after World War II. During the war, the U.S. Army Chemical Corps and the U.S. Atomic Energy Commission developed the HEPA filter to protect against radiation while working on the Manhattan Project. Once the war ended, the U.S. government released the HEPA filter designs to the public, and manufacturers swiftly began producing these advanced filters for both industrial and residential use.

Over the years, advancements in filter medium materials and filter systems have significantly improved their efficiency. In the 1970s, growing concerns about air and water pollution led to stricter regulations. The Clean Water Act of 1972, for instance, required industrial manufacturers to implement improved waste management practices to prevent contamination of water sources. Since then, the importance of air cleaners and industrial water filtration systems has only increased, extending to critical applications in fields like aerospace and aeronautics.

How Filtering Systems Work

Filtration systems vary widely in their approach to material separation. For instance, certain systems achieve this by suspending solids, while membrane filtration systems capture contaminants through specialized media as they move through the filter. Other methods involve trapping contaminants within foam. Additional techniques might utilize centrifugal force, gravity, or biological agents, and some even use electrically charged particles. Systems may also apply hydrostatic or rotational pressure to extract heavier particles.

Types of Filtering Systems

Vacuum filters operate by generating pressure at the filter media’s outlet that exceeds the pressure of the surrounding atmosphere. Essentially, these filters create a vacuum, which draws the outside air into this lower-pressure zone. As the air moves into the vacuum, it comes into contact with the filter media.

Pressure filters operate by using pressurized fluid or compressed air to push a liquid through their filter media. As the liquid flows through, the filter media captures and removes suspended debris and separates out any unwanted materials.

Membrane filtration is a widely used filtration method that employs a thin, specialized sheet to separate and filter liquids.

In-line filters are strategically placed within flow lines to capture contaminants and prevent system blockages.

Chemical filters remove contaminants by extracting them from the solution as it passes through the filter.

Biological filters are capable of removing organic compounds, though this application is less commonly utilized.

Two distinct types of filtration systems utilize electrical charges to purify air or fluids: electrodialysis systems and electrolysis reversal systems.

Electrodialysis systems (ED) use membranes that permit the passage of either negatively charged or positively charged ions, but not both types simultaneously.

Electrolysis reversal systems (EDR) operate in a comparable manner, but they periodically reverse the current to create a new flow.

Less common filter types include reverse osmosis (RO), ultrafiltration (UF), and electrodeionization (EDI). While these filters are not as widely used as ED or EDR systems, they offer comparable efficiency and unique benefits of their own.

Reverse osmosis systems operate by forcing pressurized water through a membrane, which acts as a barrier to prevent impurities from passing through.

Ultrafication filters are crafted to capture particles and microorganisms ranging from 0.003 to 0.1 micrometers. This size range includes entities such as viruses and bacteria.

Electrodeionization filters combine electricity, membranes, resin, and ion exchange to purify water. By deionizing the water, these filters effectively remove dissolved ions, ensuring a high level of purity.

Progression filtration systems are an excellent choice for industries where solid recovery is crucial. These systems excel at sorting contaminants by their size, ensuring effective separation and recovery.

Our oil filtration systems are expertly engineered to handle the specific needs of oil filtration. Essential for a wide range of machinery—from cars and trucks to manufacturing and agricultural equipment—these systems efficiently remove contaminants from all types of oil, including hydraulic and motor oil.

Coalescing filters are a specialized type of filter crafted to meet precise specifications. Coalescing filters excel at capturing and eliminating mists, vapors, and oils from process air streams.

Water filters purify tap water, drinking water, and wastewater by eliminating contaminants, microorganisms, and particles. They are also used as refrigerator water filters in systems that produce ice and water.

Pool filters are specialized devices crafted to purify pool water. Typically, these filters come in the form of compact, removable cartridge systems.

HEPA filters, which stands for High Efficiency Particulate Air filters, are engineered to capture up to 99.99% of airborne particles. These filters play a crucial role in maintaining clean air in environments such as airplane cabins, industrial vacuum systems, and respiratory equipment, among others. To earn the HEPA designation, filters must undergo certification to meet stringent performance standards.

Magnetic filtration or separation involves using strong magnets to extract magnetic materials, such as metal shavings and loose debris, from mixtures. This process is vital for quality control across various industries, including food, oil and gas, water treatment, and pharmaceuticals, all of which handle fluids. Magnetic filtration systems play a crucial role in ensuring the cleanliness and efficiency of industrial processes. For prospective business owners and designers, understanding the benefits of these systems is essential in determining whether they represent a valuable investment for your facility.

Advantages and Benefits of Magnetic Filtration Systems

Reusable Technology and Reduced Costs

This type of filtration offers a far more economical solution for particle removal compared to disposable filters. Once a magnetic filter is installed, the ongoing costs are minimal, with no additional expenses throughout its lifespan. In contrast, disposable filters demand regular purchasing and replacement, making them less cost-effective and more time-consuming to manage.

Improved Fluid Flow

Magnetic filters and grates offer less resistance to fluid flow compared to conventional filters. Unlike other types, where the flow can be obstructed once the filter media becomes clogged with particles, magnetic filters, such as plugs and rods, work continuously to remove contaminants while maintaining a smooth flow with minimal interruption.

Provides Support to Conventional Filters

They are highly efficient on their own, but they also enhance conventional filtration systems when used together. By integrating magnetic filters with standard filters, you can ease the burden on the conventional filters, reducing their strain and boosting their ability to capture residual particles. This not only improves the overall filtration effectiveness but can also extend the service life of conventional filters, sometimes by two to three times.

Environmentally Friendly

Magnetic filters contribute to environmental sustainability by significantly reducing the need for disposable filters such as paper and cartridges. They keep industrial fluids, including coolants and oils, clean, which minimizes their consumption and substantially lowers disposal requirements. Additionally, magnetic filters facilitate the easy recycling of captured ferrous particles. In contrast, conventional filters trap contaminants in their media, necessitating their disposal as hazardous waste.

Improves Electro-Hydraulic Valves

In facilities utilizing electro-hydraulic valves and power, implementing magnetic filtration systems is crucial. Magnetic filters effectively capture ferrous particles that could disrupt or damage electro-hydraulic valves. By incorporating magnetic filtration, the reliability of these valves is significantly enhanced, promoting safer machine operation and minimizing potential future issues.

Reduced Risk of Oil Oxidation

Oil oxidation is a natural phenomenon that happens when oils and lubricants come into contact with metallic particles, leading to the formation of sludge, rust, and corrosion. To address this, magnetic filters offer a continuous and efficient solution by removing these metallic particles. This process enhances the oil’s quality and minimizes the need for unwanted disposal.

Better Gravity Flow

Numerous machines and systems rely on gravity to move liquids through pipes and connections. However, the pressure from gravity flow is often insufficient for conventional filters to effectively remove particles and contaminants. Magnetic filters, rods, and plugs, on the other hand, typically do not impede the flow, allowing particles to be swiftly and easily removed even when gravity is the sole source of pressure.

Filtering System Design and Customization

When designing and customizing filtration systems, manufacturers need to account for a diverse array of application specifications. This includes the type of stream to be processed, the specific particles or contaminants to be removed, the environment in which the system will be used—whether it’s a home, factory, hospital, or other setting—and the relevant standard requirements.

Filtration system manufacturers determine the appropriate filter pore sizes by considering the material being processed, the intended purpose of the filter, and the particle size.

Manufacturers carefully evaluate these details to determine the optimal filtration rate—the speed at which a stream passes through a filter while achieving the highest level of particle separation and removal. To achieve this optimal rate, they might position the filter at various points within a system: at the intake, inline, or at the exhaust. In some cases, multiple filters may be employed at each of these locations. This approach enables repeated separation and removal of particles throughout the flow, enhancing product quality and allowing filters to operate more efficiently by minimizing clogging from larger particles.

They can determine the most suitable filter media by evaluating various factors, including filter location, rate, load capacity, absorption, and other relevant variables.

Manufacturers utilize a variety of materials for producing filter housings and cartridges, such as aluminum, plastic, steel, and stainless steel. For the filter media itself, materials like carbon, Teflon, resin, nylon, sand, and synthetic fibers are commonly employed. Each material brings unique benefits: for instance, carbon is particularly effective at eliminating chlorine, volatile organic compounds, and unpleasant smells from water.

Filtering System Safety and Compliance Standards

Different filters must adhere to varying standards depending on their specific location and application. Numerous organizations, including ASTM, ANSI, and ISO’s Technical Committee 131, establish filtration system standards that some organizations use as foundational guidelines. For instance, ANSI collaborates with the American Society for Healthcare Engineering to develop standards specifically for hospital filtration systems. Additionally, HEPA filters are required to meet standards set by both the U.S. Department of Energy (DOE) and the National Institute for Occupational Safety and Health (NIOSH). To ensure that your filters comply with the necessary standards, consult with industry experts.
