Flowceptor^®

STORMWATER QUALITY IMPROVEMENT DEVICE

Flowceptor^® is a horizontally configured two-chamber Stormwater Quality Improvement Device (SQID), equipped with a gravity enhancing coalescer unit. For those with medium to low-risk applications, the Flowceptor Class 2 model (with no coalescer unit) is also available.

The advanced design facilitates a retention period that provides quiescent conditions within the secondary chamber, efficiently promoting the separation of total suspended solids (TSS), light liquids and pollutants. Atlan treatment devices can accommodate a complete range of flow rates with corresponding pipe size and types.

Flowceptor (Formerly SPEL Stormceptor) FAQ

What is the Flowceptor, and how does it differ from other stormwater treatment devices?

The Flowceptor is a horizontally-configured, two-chamber Stormwater Quality Improvement Device (SQID) designed to separate and capture hydrocarbons, gross pollutants, and suspended solids. Unlike other stormwater treatment devices, Flowceptor offers two models: Class 1, which includes a gravity-enhancing coalescer unit for high-risk applications, and Class 2 for medium to low-risk environments without the coalescer.

What are the differences between primary, secondary and tertiary stormwater management solutions?

The differences between primary, secondary, and tertiary stormwater management solutions can be described as follows:

Primary Stormwater Management Solutions

Primary stormwater management solutions (often referred to as primary gross pollutant traps) focus on the initial capture and removal of the largest pollutants from stormwater, such as debris, leaves, and coarse sediments. These systems typically include screens, grates, or sedimentation basins that filter out the bulk of pollutants before the water moves to the next treatment stage. While effective at capturing large particles, primary solutions do not address finer pollutants or remaining solids.

Secondary Stormwater Management Solutions

Secondary stormwater management solutions are designed to remove finer particles and suspended solids that pass through primary treatment systems. These solutions often involve the use of settling tanks, filters, or oil-water separators, which can capture smaller particles, hydrocarbons, and light liquids. Secondary treatments significantly reduce the concentration of pollutants but may still leave behind very fine or dissolved remaining solids.

Tertiary Stormwater Management Solutions

Tertiary stormwater management solutions are the final stage of treatment and are aimed at removing the remaining solids and dissolved pollutants that were not captured during the primary and secondary stages. These advanced treatments often include filtration systems, biological treatment, or chemical processes that target the smallest particles and nutrients, such as nitrogen and phosphorus. Tertiary solutions are essential for ensuring that stormwater is of high enough quality to meet environmental standards before it is discharged into natural water bodies.

What applications are ideal for the Flowceptor?

The Flowceptor is suited for a wide range of industrial, commercial, and transport settings, including car parks, shopping centres, council depots, industrial estates, airport aprons, loading bays, tunnels, and recycling yards. Its design is particularly beneficial in environments that require efficient separation of pollutants and hydrocarbons from stormwater.

What sizes are available for the Flowceptor?

The Flowceptor can accommodate pipe sizes ranging from 160mm to 1500mm, including box culvert designs. Larger sizes are also available upon request, making it adaptable to various project requirements.

How does the Flowceptor ensure effective pollutant removal?

Flowceptor’s advanced design promotes quiescent conditions within its secondary chamber, facilitating the separation of total suspended solids (TSS), light liquids, and pollutants. This ensures efficient removal of contaminants in one treatment system.

Is the Flowceptor compliant with Australian regulations?

Yes, the Flowceptor is designed to meet Australian conditions and complies with the objectives set by regulating authorities, ensuring it meets the required standards for stormwater quality improvement.

What maintenance is required for the Flowceptor?

The Flowceptor is designed for easy, simple, and safe maintenance. There is no need to enter the tank, as all necessary maintenance can be performed externally, reducing risks and operational downtime.

What is MUSIC modelling, and can it be provided for Flowceptor installation?

MUSIC (Model for Urban Stormwater Improvement Conceptualisation) improves the efficiency of stormwater systems. Model for Urban Stormwater Improvement Conceptualisation (MUSIC) modelling is available for various councils and regions throughout Australia. This service helps ensure that the Flowceptor is optimised for local environmental conditions.

How does the Flowceptor differ from the Spillceptor?

The Flowceptor and Spillceptor serve different purposes within stormwater management, each designed for specific applications.

Flowceptor (formerly Spel Stormceptor):

This device is a two-chamber Stormwater Quality Improvement Device (SQID) optimised for the regular separation and removal of pollutants such as total suspended solids (TSS), light liquids, and hydrocarbons from stormwater. It is available in two models:

• Class 1: which includes a gravity-enhancing coalescer unit for high-risk environments

• Class 2: suited for medium to low-risk applications without the coalescer. The Flowceptor is ideal for general stormwater treatment across various commercial, industrial, and transport settings, such as car parks, shopping centres, and highways.

Spillceptor (formerly SPEL Puraceptor):

The Spillceptor is a full retention separator specifically designed for high-risk applications where oil spills are a significant concern. It treats all flows and is equipped with an Automatic Closure Device (A.C.D.) that automatically responds to changes in water density due to light liquids buildup, ensuring immediate containment of major spills.

The Spillceptor is engineered to achieve a water discharge quality of less than 5mg of light liquids per litre, meeting stringent European standards. It is best suited for high-risk environments such as power stations, mining operations, renewable energy sites, and service stations.

To summarise:

The Flowceptor is best for general stormwater quality improvement across a variety of environments, while the Spillceptor is designed for high-risk areas requiring robust spill containment and continuous treatment of all stormwater flows.
