StormFilter

The most proven stormwater filtration system

The StormFilter is a stormwater filtration system containing replaceable, media-filled cartridges filled with filtering media that retain particles and sediments, and adsorb pollutants such as phosphorus, oils and grease, soluble metals, nutrients and organics1 .

  • Easy access for maintenance (1).
  • Includes standard ductile iron frame and cover (optional: adjustable type) (2).
  • O-ring gasket into the walls of the system2 make it easy to connect all types of pipes: HDPE, PVC and concrete (3).
  • Installation similar to a traditional concrete vault or manhole.
  • Designed to resist CL-625, H-25 and HS-25 loads.
  • Offered exclusively by Soleno in Quebec and the Atlantic Provinces.

Advantages and Benefits

  • Replaceable cartridges that allow the use of different filtering medias.
  • Effectively removes 80%* of TSS and adsorbs dissolved pollutants.
  • Equipped with an optional internal bypass system, it controls peak flows; the StormFilter’s treatment capacity is maintained during high intensity events.
  • Flexible designs accommodate multiple inlet and outlet pipe locations and angles.
  • Fits inlet and outlet pipes up to 900 mm (36 in) for high flow rate applications.
  • Designed for specific standardized treatment quality flow rates, the StormFilter provides customized solutions for each project.
  • Pre-assembled at the factory, installation and assembly on site are simple and quick.
*See current local regulations.

A Versatile Device

Flexible Configurations All-in-one Configuration Manholes Standard Vaults Vault with internal bypass

Flexible Configurations

  • StormFilter offers a complete range of configurations that can be adapted to different flow rates, available ground space and project-specific hydraulic data.
  • In certain circumstances, different control devices such as control valve or flow regulator, can be integrated into the system.

 

All-in-one Configuration

  • Combines all the structures required in a traditional treatment system, by combining the functions of an inlet, a bypass structure and a junction unit into a single structure.
  • This grouping saves money by reducing the number of structures to be installed, the footprint and excavation requirements.
  • For certain models, a flow regulator and an additional overflow can be installed inside the unit.

 

Model shown: PD811 StormFilter

Manholes

  • 4 models
  • 1200 mm t 2400 mm (48 in to 96 in) in diameter
  • Treatment flow rate up to 16.6 l/s

 

Model shown: MH60 StormFilter

Standard Vaults

  • 9 models
  • 2400 mm x 1800 mm (96 in x 72 i) à to 2400 mm x 7200 m (96 in x 288 in)
  • Optional internal bypass
  • Treatment flow rate up to 72.4 l/s

Vault with an Integrated Bypass Structure

An advantageous configuration!

During rain events generating flow rates below the system’s treatment capacity, the operation of the vault with an integrated bypass structure remains the same as that of the standard vault.

When the flow rate exceeds the treatment capacity of the system, the excess flow is diverted to the outlet chamber over the weir wall. By segregating the treatment bay from the high velocity peak flows, the cartridges continue to operate normally which maintains performance and retains settles pollutants.

Proven and Approved

  • Stormwater filtration system approved by the MELCC.
  • Approved by the Washington State Department of Ecology (GULD* certification level) and the New Jersey Department of Environmental Protection (NJDEP).
  • Tested in a variety of environments; in the laboratory and in the field, the StormFilter has proven itself for over 20 years.
  • Constantly tested and refined to ensure maximum reliability and performance in accordance with the latest applicable standards.
* General Use Level Designation

Solves the most Stringent Problematics

Solves the most stringent problematics in stormwater treatment

The evolution and implementation of a more stricter regulatory framework is gradually transforming traditional practices towards integrated stormwater management. Sewer system owners and managers must use new treatment solutions while ensuring the sustainability of infrastructure, in accordance with new environmental requirements. In addition to the removal of total suspended solids (TSS), oils and floating debris, the significant removal of nutrients, soluble metals and hydrocarbons from stormwater is now required.

The performance of the StormFilter filtration system has been verified and approuved by the Washington State Department of Ecology and approved by the MELCC.

Unique Filter Cartridges

Unique Filter Cartridges

StormFilter replaceable filtering cartridges are available in three activation heights to meet the specific hydraulic needs of the project, such as water level and treatment flow rate

Activation Heights

  • By providing a treatment capacity 50% higher than the medium cartridge, the large cartridge is ideal for reducing the number of cartridges required, and therefore the footprint of the structure, while meeting the same treatment performance.
  • With a minimum hydraulic drop of 550 mm (21.7 in), the small cartridge is suitable for sites with shallow hydraulic profiles.

Replaceable and Self-Cleaning

  • The configuration of the cartridge reduces the clogging of its filter media, ensuring the use of its entire contact surface and thus extending its lifespan.
  • Replaceable filtering media cartridges that make maintenance easier and reduce operating costs.

Effective Treatment

  • Once the siphon is activated, stormwater is drawn radially through the large surface of the filtering media for effective treatment.

Filtering Media

Different types of filtering media are available, targeting TSS, phosphorus, soluble metals and nutrients.

  • PhosphoSorbTM is a lightweight media built from a perlite base that removes total phosphorus (TP) by adsorbing dissolved-P and filtering particulate-P simultaneously.
  • Available on request, ZPGTM a proprietary blend of zeolite, perlite and granular activated carbon (GAC), enhances perlite* performance and targets organic compounds, soluble metals and other pollutants.

Handling and Maintenance

  • Lightweight, handling the cartridges to be maintained does not require any integrated lifting equipment, making system maintenance easier and faster.
  • The cartridges are pre-installed at the factory.
