Overview
Our cartridge filter system, AtlanFilter®, is a tertiary stormwater filtration system that incorporates an upflow treatment process which maximises surface treatment area. Flow through the filter cartridges utilises a self-regulating siphon which results in a low maintenance and high performance treatment of stormwater runoff. The automatic backwash at the end of each storm event further lengthens the lifespan of the stormwater treatment filter.
Hydraulic pressure forces water through the filter media — causing a constant velocity throughout the filter area realising a consistent media contact time and therefore treatment. Upon completion of a stormwater treatment cycle, the filter backwashes and effectively dislodges particulates from the filtration layers.
High-Efficiency Inorganic Media
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.
Advanced Filtration Technology
Utilises up-flow filtration to effectively capture pollutants such as sediment, hydrocarbons, heavy metals, phosphorus, nitrogen, and total suspended solids (TSS).
Flexible Flow Rate Capability
Offers 3 LPS for full height and 1.5 LPS for half height filters, with SQIDEP-verified performance.
Easy Installation and Maintenance
Lightweight, no-crane installation with straightforward maintenance and easy cartridge access for pollutant removal.
Compact Design
Compact footprint with fully customisable configurations, accommodating anywhere from 1 to an unlimited number of filter cartridges, making it ideal for constrained sites with minimal installation space.
Durable Construction
AtlanFilter’s design has no moving parts which increases reliability, longevity and durability.
How it Works
The AtlanFilter has an upflow treatment process that maximises surface area. The innovative cartridge filter system provides excellent pollutant removal in a small footprint.
Hydraulic pressure forces water through the filter media, which discharges through the centre tube and out through the outlet collection manifold.
Upon completion of a treatment cycle, each cartridge backwashes and effectively dislodges particulates from the filtration layers. This reestablishes filter media porosity. The dislodged particles accumulate on the vault floor for easy removal during maintenance. AtlanFilter’s design has no moving parts and generates a true siphon effect.
AtlanFilters are often installed downstream of nearby devices in a treatment train. For example, an Atlan GPT upstream greatly increases the life cycle interval of the AtlanFilter. These devices will remove larger gross pollutants, coarse sediments, total suspended solids and hydrocarbons – enabling the AtlanFilter to target fine particulate matter and nutrients.

AtlanFilter (SPEL Filter) FAQ
What are Total Suspended Solids?
Total Suspended Solids (TSS) refer to solid particles suspended in water, which can include materials like silt, decaying plant matter, industrial waste, and sewage. High levels of TSS can harm aquatic life, reduce water quality, and contribute to the pollution of water bodies.
The AtlanFilter is designed to effectively remove 85% of TSS from stormwater, helping to maintain environmental standards and improve water quality by providing capabilities for the removal of heavy metals and other pollutants.
Can you explain primary, secondary, and tertiary stormwater treatment?
Stormwater treatment typically involves three stages:
- Primary Treatment: The first stage involves removing larger particles and debris from the water using screens, sedimentation basins, or grit chambers that trap and settle out solids.
- Secondary Treatment: This stage focuses on reducing organic matter, hydrocarbons, and smaller suspended solids that remain after primary treatment. Separation, biological process, and filtration are commonly used in this stage to further purify the water.
- Tertiary Treatment: The final stage, tertiary treatment, involves advanced filtration methods to remove finer particles, nutrients, heavy metals, and other contaminants that were not captured during primary and secondary treatments. The AtlanFilter system is a tertiary treatment solution, providing a high level of pollutant removal, including TSS, Total Phosphorus (TP), and Total Nitrogen (TN).
How does the AtlanFilter cartridge filter system work?
What pollutants can the AtlanFilter remove from stormwater?
The AtlanFilter is optimised to remove specific pollutants, including 85% of Total Suspended Solids (TSS), 74% of Total Phosphorus (TP), and 59% of Total Nitrogen (TN). Its advanced filtration also targets heavy metals and other contaminants, making it highly effective in treating stormwater runoff in various applications, such as car parks, industrial estates, and transport depots.
What is MUSIC modelling, and how can it be accessed for the AtlanFilter?
Can filter cartridges be used for sediment control?
The Atlan SediFilter is our AtlanFilter analogue for sediment control applications – such as construction sites, ongoing development, civil works and infratructure projects. Using a similar filter cartridge configuration to AtlanFilter, the Atlan SediFilter is specifically designed for the capture of sediment and construction sediment such as sand, soil, cement and other building materials.
