Self-Cleaning Filtration. Verified Performance.
At Jensen, we deliver proven solutions that manage runoff, protect waterways, and maximize site efficiency. Through our partnership with Atlan, we offer AtlanFilter, a high-performance stormwater filtration system engineered for consistent, verified water quality treatment. Featuring an up-flow cartridge design and a self-regulating siphon with automatic backwash, AtlanFilter restores filtration capacity after storm events without moving parts, reducing maintenance and long-term operating costs. Its reusable, swap-and-go media cartridges simplify servicing and minimize downtime, while modular, customizable configurations allow the system to fit constrained sites and scale to project-specific needs. Backed by independent performance verification and Jensen’s manufacturing and technical expertise, AtlanFilter delivers reliable treatment, efficient installation, and long-term value for engineers, property owners, and municipalities alike.
Multiple Cartridge Sizes. One Flexible Filtration System.
AtlanFilter is a high-performance stormwater filtration system engineered to deliver consistent, verified water quality treatment with minimal maintenance. Its up-flow cartridge design maintains constant velocities for efficient pollutant removal, while the self-regulating siphon and automatic backwash restore media capacity after each storm event—without moving parts. This innovative operation reduces maintenance frequency, extends media life, and lowers long-term operating costs, providing reliable performance engineers and owners can trust.
To accommodate varying site conditions and treatment requirements, AtlanFilter offers multiple cartridge sizes and flexible system configurations. Cartridge options can be selected and combined to match flow rates, pollutant loads, and available footprint, allowing the system to scale from compact installations to large treatment applications. This modular design enables efficient layouts, simplified installation, and straightforward maintenance access, ensuring AtlanFilter can be tailored to meet the unique demands of each project.
Features & Benefits
Utilizes up-flow filtration to effectively capture pollutants such as sediment, hydrocarbons, heavy metals, phosphorus, nitrogen, and total suspended solids (TSS).
Compact footprint with fully customizable configurations, accommodating anywhere from 1 to an unlimited number of filter cartridges, making it ideal for constrained sites with minimal installation space.
AtlanFilter’s design has no moving parts which increases reliability, longevity and durability.
Suitable for manholes, OSD tanks, vaults, and both trafficable and non-trafficable zones, providing adaptable stormwater solutions.
AtlanFilter’s inorganic filter media ensures it doesn’t leach nitrogen and other nutrients. Providing high removal efficiencies, the cartridge system is designed for high flow capacity and greater surface area for stormwater treatment.
Lightweight, no-crane installation with straightforward maintenance and easy cartridge access for pollutant removal.
Offers 47.6 GPM for full height and 23.8 GPM for half height filters, with SQIDEP-verified performance.
Inorganic media prevents nutrient leaching, ensuring efficient and reliable treatment outcomes.
