What's in an underdrain? We often get asked, why Everfilt® underdrains are superior or built differently. When it comes to selecting underdrains for your filtration system, it's crucial to make an informed decision. Let's explore the advantages of stainless steel wedge wire underdrains, highlighting their superior features compared to alternative options.
Strength & Durability
Stainless steel underdrains offer unparalleled strength and durability. Unlike molded plastic or PVC collectors, which can deform under high-pressures and heat, as well as break from impact during filtration media loading, stainless steel maintains its integrity even in challenging conditions. This means you can rely on stainless steel underdrains for long-term, reliable filtration performance.
Epoxy Coating Compatibility
One significant advantage of stainless steel underdrains is their compatibility with interior coatings. Unlike some alternatives that require underdrains to be installed before coating, stainless steel underdrains can be assembled after the coating process. This flexibility simplifies installation and ensures a seamless, corrosion-resistant interior surface in your tank. Removable or welded in place underdrain assemblies allow customization beyond your expectations, and ensures coating and underdrain design are not sacrificed during the process.
Gravel-Free Filtration
Unlike underdrains that necessitate the use of gravel to aid in back-flushing water dispersion, stainless steel wedge wire underdrains eliminate this need. This simplifies the setup and maintenance process, making them a more efficient choice for your filtration system. Computer aided underdrain design creates an even flow of backwash water at all times, eliminating "HOT SPOT" or media channeling, while in a backwash cycle.
Removable Stainless Steel Underdrain Design
The removable threaded stainless steel construction of wedge wire underdrains provides an extra layer of stability. This design minimizes the risk of damage from hard objects, ensuring the longevity of your filtration system. In contrast, PVC-based underdrains can be vulnerable to damage if subjected to sharp or heavy objects.
Sand, gravel and debris do not work well with PVC threads, as they tend to be soft and can become damaged during maintenance.
Greater Filtration Depth
Stainless steel wedge wire underdrains boast an innovative design with ends that articulate upward. This feature allows the underdrain to sit lower in the tank, accommodating a greater depth of sand for enhanced filtration efficiency. This design element can significantly improve the overall performance of your filtration system.
No Need for Safety Screens
Unlike some other underdrain options, stainless steel wedge wire underdrains do not require the use of safety screens. This eliminates an additional component, simplifying the installation process and reducing maintenance requirements.
Corrosion Resistance
Stainless steel tanks and underdrains DO NOT require special coatings to protect the tank's interior from corrosion, this investment ensures a long-lasting and corrosion-resistant filtration solution. For carbon steel tanks, specialized coatings provide an added layer of protection, guaranteeing the longevity of your filtration system.
When it comes to choosing underdrains for your filtration system, the superior choice becomes clear: stainless steel wedge wire underdrains. Their unmatched strength, durability, compatibility with epoxy coatings, and fuze coatings, paired with innovative design, make them a reliable and efficient option for any filtration application. Invest in the longevity and efficiency of your filtration system with stainless steel wedge wire underdrains. Make the smart choice for your filtration needs.
