Self-Cleaning Strainers and How They Work
July 24, 2024

Self-cleaning strainers offer an efficient and continuous way to remove debris and contaminants from fluid systems without the need for manual intervention. In this blog, we’ll discuss what self-cleaning filters are, how they work, and their various benefits in industrial filtration.

What Are Self-Cleaning Filters?


Automatic self-cleaning strainers keep industrial process systems free of contaminants and debris as with traditional strainers and filters. What makes self-cleaning strainers unique is how they clean themselves without shutdowns and manual intervention. 

In most self-cleaning strainer designs, liquid enters the strainer from the bottom, flows upward through a filtering system, and exits as clean fluid. Any debris caught by the filter is pushed to a collection area. When the system detects a buildup of pressure, it opens a flush valve to remove the collected debris. 


The most common mechanisms you will see in a self-cleaning strainer include:


  • Backwashing. The flow of the liquid is reversed to send a portion back through the filter. This dislodges trapped debris so that it can be directed to the collection area.

  • Mechanical Scraping. Uses blades to physically scrape the filter surface.

  • Continuous Flushing. A bypass stream continuously dislodges and carries away contaminants while the main fluid passes through the strainers.

  • Ultrasonic Cleaning. Uses high-frequency vibrations to break apart and dislodge stubborn debris so that it can continue to the collection area.


The longer a filter can go without shutdowns for cleaning and repairs, the greater the savings lost production.

Benefits of Automatic Self-Cleaning Strainers


The advantages of using a self-cleaning strainer are not limited to productivity and reduced downtime. Other benefits include:


  • Consistent performance in flow rate and purity
  • Prevents damage and repairs due to clogs in the filter 
  • Protects downstream equipment from damage due to clogs and impurities


Is a Self-Cleaning Strainer Right for my Filtration Needs?


Every work sight and process is unique, so what works perfectly at one site may not work well at another. This holds true with self-cleaning strainers as well.


Before you invest in a self-cleaning strainer, you should discuss your needs with one of SCI’s knowledgeable employees. They will help you navigate factors to consider. This includes factors such as maximum flow rate, pressure, strainer mesh sizing and material compatibility to ensure the strainer will not corrode on contact with the fluid.

How Advanced Filtration Systems Help Future-Proof Regulatory Challenges in Water Quality

By Keith Adams • January 27, 2025
Businesses and industries face a lot of changes in the coming years. Advanced filtration systems are essential tools that can help meet these evolving standards before they become an issue. Here are a few ways to future-proof your businesses against water quality regulations. Managing PFAS and Emerging Contaminants One of the most pressing challenges is regulating PFAS (per- and poly-fluoroalkyl substances), also known as “forever chemicals.” PFAS have been linked to significant health risks like cancer, heart disease, and immune system disorders. Advanced filtration technologies defend against PFAS and other emerging contaminants. Three effective options that meet or exceed regulatory standards include: Reverse Osmosis (RO). RO systems use semi-permeable membranes to remove up to 99% of contaminants, including PFAS, heavy metals, and bacteria. Granular Activated Carbon (GAC). The right GAC filters can adsorb PFAS molecules, volatile organic compounds (VOCs), and other pollutants. Ion Exchange Systems. These systems target specific contaminants and bind to them during the removal process. By integrating these technologies, businesses can meet or exceed regulatory thresholds for water safety before they go into effect. It also ensures they protect their employees, customers, and reputation as our knowledge of PFAS and other contaminants continues to evolve. Supporting Sustainability Goals Advanced water filtration systems help meet sustainability-focused regulations, including those that could appear in coming years. Reducing Water Waste. Stricter laws are targeting water conservation and waste reduction across industries. New filtration designs and custom filtration services allow for things like closed-loop systems that recycle used water. Lowering Environmental Impact. When the situation allows, advanced filtration processes like UV disinfection or ozone treatment minimize reliance on chemicals, reducing both cost and environmental risk. Compliance with Green Certifications. Compliance with green initiatives often comes with benefits like tax incentives or operational grants. Modern systems designed to meet water efficiency and waste reduction benchmarks help businesses achieve these certifications more easily. Businesses who take a sustainability approach to their water filtration systems will future-proof themselves to rising environmental standards and position themselves as leaders in environmentally responsible practices. Staying Prepared for Water Quality Crises The winter storm of January 2025 showed us that emergency preparedness should be a top priority to avoid or minimize regulatory issues during unexpected events. A few ways advanced systems help mitigate these risks include: Rapid Response Capabilities. Portable filtration units or mobile treatment systems can be deployed to manage emergencies quickly. Real Time Warnings and Automatic Controls. Using filtration and quality controls like real time meters, alarms, and pH regulators can help businesses deal with issues before they build up into regulatory breaches. System Redundancy. Designing systems with backup capabilities ensures uninterrupted compliance even during disruptions like frozen pipes or blockages from storm debris. Businesses can minimize compliance risks and stay prepared for future challenges by adopting filtration systems that can quickly adapt to unplanned situations. This proactive approach will safeguard against fines and penalties, ensure operational continuity, and future-proof your system against sudden regulatory issues.  Sparkling Clear Will Help Future-Proof Your Filtration Systems If your business is ready to upgrade its water filtration systems to meet the latest and future regulatory challenges, contact us today. Our team will provide tailored solutions designed to keep your operations compliant and running smoothly.

The Hidden Link Between Water Quality and Energy Efficiency

The Hidden Link Between Water Quality and Energy Efficiency

Why Use Membranes?

July 16, 2024
At Sparkling Clear, we understand the importance of using membrane cartridges for filtration. The pore structure of our membrane cartridges ensures extremely high retention efficiency and consistent effluent quality. This capability to capture and retain very small particulates and organisms instills a high degree of confidence that your product will be clean and safe for use. The consistent pore structure of our membranes also allows for straightforward testing, helping both manufacturers and users to understand and communicate the expected performance of the cartridge in various applications. This is why membrane filters are typically employed in scenarios where the removal of submicronic contaminants is crucial. It is important to note that membrane filters are generally used in the final stages of a filtration process. To ensure the longevity and efficiency of the membrane cartridge, it is essential to protect it with prefilters. This protection prevents premature fouling and maximizes the economic value of the system. Applications that Usually Require Membranes: Submicronic particulate removal Removal of microorganisms (bacteria, viruses, etc.) Applications requiring sterility (liquid or gas) Endotoxin removal Haze removal (typically caused by high concentrations of particles at or below 0.45 microns) Choose Sparkling Clear for your membrane filtration needs to ensure the highest quality and safety of your products.
