Everything You Need To Know About Industrial Sand Filters
Jul 17, 2023
Industrial sand filters are essential to various industrial processes and wastewater treatment systems. They are designed to remove solid particles and impurities from liquids, making them suitable for further use or discharge. Here's everything you need to know about industrial sand filters.
What Is An Industrial Sand Filter?
An industrial sand filter is used in various industries to remove solid particles and impurities from liquids. It consists of a vessel or tank filled with a layer of specially graded sand or other granular media like activated carbon, diatomaceous earth, and gravel. They can come with one layer of media or multiple layers of mixed media.
Industrial sand filters improve the quality and clarity of the liquids that pass through them by trapping suspended solids, sediments, debris, and organic matter. After removing the contaminants, the fluid is transported to the next stage of its journey in a cleaner and more refined state.
Advantages of Industrial Sand Filters
Industrial sand filtration systems offer several advantages. Here are just a few:
Effective Particle Removal. The specially graded sand or other granular media in the filter bed effectively traps various impurities. The effectiveness it has against each type of impurity depends on the grade and type of sand used.
Versatility. Industrial sand filters can handle various liquid types and flow rates. This makes them adaptable to different industries and filtration requirements.
Cost-Effective. Industrial sand filters are often cost-effective compared to other filtration technologies. They also have low operational costs, requiring minimal energy consumption and maintenance.
Long Service Life. In most cases, sand can be cleaned and reused multiple times before replacement is required. The durable construction of the filter tank and components further contributes to the longevity of the system.
Regulatory Compliance. Sand filters help ensure compliance with environmental regulations by removing solid particles and impurities from liquid streams.
The advantages of industrial sand filtration may vary depending on the specific application, system design, and operational parameters. Consult with filtration experts and engineers to optimize the advantages of sand filtration for your particular industry or process.
Challenges and Maintainance Needs
While industrial sand filtration systems offer numerous advantages, they also present certain challenges and maintenance needs. Here are a few common ones to keep in mind:
Clogging and Pressure Drop. Over time, the filter bed can become clogged with accumulated solids, reducing the flow rate and fluid pressure in the process. You will need to perform backwashing as needed to remove trapped particles and restore optimal flow.
Backwashing. Backwashing involves reversing the water flow through the filter bed to dislodge and flush out trapped solids. Proper backwashing procedures, including flow rates and duration, must be followed to ensure effective cleaning without damaging the filter media. Your filtration experts can help you determine the right procedure for your system.
Media Replacement and Refilling. Over time, the filter media may require replacement due to degradation, loss of efficiency, or physical damage. The frequency of media replacement depends on factors such as the nature of the filtered liquid, filtration load, and operational conditions. Media replacement involves draining the filter, removing the old media, and refilling it with new, properly graded media.
Monitoring and Testing. Regular monitoring of key parameters like pressure, flow rates, and quality is crucial to ensure the effective operation of the filtration system. You will also need to periodically test the filtered liquid for quality and compliance with regulatory standards.
It is important to follow the specific manufacturer recommendations from your filtration experts for maintenance procedures and schedules. Regular and proactive maintenance helps optimize the filtration system's performance, extend its service life, and ensure the quality of the filtered liquid.

On February 8, 2024, the EPA proposed adding a group of chemicals known as per- and polyfluoroalkyl substances (PFAS), also known as “Forever Chemicals,” to the Resource Conservation and Recovery Act (RCRA) Section 3001 hazardous waste list. This proposal carries significant implications for businesses and industrial processes. Let's delve into the details of this proposal and how its acceptance will affect businesses moving forward. What is in the EPA's Feb 2024 Proposal? The EPA's proposal aims to list nine PFAS compounds as hazardous waste under the RCRA. Here is the exact list: Perfluorooctanoic acid Perfluorooctanesulfonic acid Perfluorobutanesulfonic acid Hexafluoropropylene oxide-dimer acid Perfluorononanoic acid Perfluorohexanesulfonic acid Perfluorodecanoic acid Perfluorohexanoic acid Perfluorobutanoic acid PFAS are widely used in various industrial and consumer products due to their water and grease-resistant properties. However, their persistence in the environment and potential adverse effects on human health have raised concerns. Adding these nine Forever Chemicals to the list is the first step to stricter regulations regarding their use, storage, and disposal. Implications for Businesses And Industrial Processes Many states already strictly regulate or ban various forever chemicals in various industries. In Texas , we mainly see their use in oil and gas extraction, particularly in fracking. It is also still used in a wide range of consumer products, including waterproof gear and fast food products. This bill could create a massive impact across the board. Here are just a few of the major factors businesses and industries may face. Compliance Costs. This includes implementing new measures to prevent environmental contamination and how you treat PFAS-contaminated waste. It could also eventually lead to a strict ban on the chemicals, forcing industries to utilize alternatives. Cost of Rapid and Frequent Changes. As studies continue and our knowledge of forever chemicals evolve, the hazardous waste listing will enable the EPA and other regulatory agencies to enforce changes accordingly. Those who continue to use PFAS substances could face the extra expenses of staying up to date with rapidly evolving safety measures. Legal Obligations. Failure to comply could result in legal consequences, including fines and penalties. This could include legal consequences for any health and environmental damages from lingering waste products linked to the company. Waste Management Practices. Industries generating PFAS-containing waste will need to reassess their waste management practices to ensure compliance with stricter hazardous waste regulations. This may involve investing in specialized treatment technologies or outsourcing waste disposal to authorized facilities. Supply Chain Impacts. Manufacturers may need to seek alternative substances or processes to replace PFAS, leading to potential product development and sourcing challenges. Companies that have not prepared for this ahead of time will be hit hardest as they contend with a spike in demand and a low supply of alternative solutions in the early days of implementation.

Perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) are two per- and poly-fluoroalkyl substances (PFASs or “forever chemicals”) that have been widely studied and are known for their persistence in the environment. Here is a breakdown of what they are and why it is important to keep them out of your water. PFOS (Perfluorooctane Sulfonate) PFOS was historically used in a variety of industrial and consumer products, including firefighting foams, textile surfaces, paper products, and as a component in some industrial processes. Studies have suggested potential health risks associated with PFOS exposure, including: Development of cancer in employees or consumers[1]. Child development issues that could lead to legal complications for your business [2]. Risk of cardiovascular disease for employees and consumers [3]. Due to concerns about its environmental and health effects, PFOS has been largely phased out of production and use in the United States, though imported goods may still contain them in certain products. PFOA (Perfluorooctanoic Acid) PFOA was used in various applications, including the production of non-stick cookware (e.g., Teflon), waterproof and stain-resistant coatings for fabrics, and in manufacturing various consumer products. PFOA exposure has been associated with similar risks to PFOS, including cancer, heart disease, and child development issues [1][2][3]. It is also no longer used in the United States, but people can still be exposed through sources like: Imported goods from unregulated countries Fish and meats that were exposed prior to processing Contaminated soil and water supplies How Do I Keep These “Forever Chemicals” Out of My Business’s Water? The EPA updated its regulations and advisories in June 2022 to include factors like lifetime exposure and ongoing research into their environmental and health effects [4]. They are currently advising areas and industries to start taking measures to bring PFOA and PFOS chemicals, among many other chemicals, to lower levels for health and safety. Their 2023 proposal to regulate forever chemicals in drinking water will ask for more rigid restrictions on chemical levels than the current Washington state action levels (SALs) [5]. Protecting your drinking and consumer product water supplies is increasingly essential for health and regulatory standards. One of your first lines of defense is your water filters and systems. A few options include reverse osmosis, activated carbon, and anion exchange. You will need to have your water tested to find the most effective measures for your site.
