This document is the BayFilter Brochure. Filter operation, design, cartridges, configuration installation and specifications explained.

The BayFilter system utilizes well proven sand filter principles to remove pollutants such as sediments, oils, metals, organics and nutrients.

The BayFilter system consists of modular cartridges placed in vaults for stormwater treatment. The cartridge consists of a spiral wound media filter cartridge utilizing a sand mix with over 43sf of active filtration. The cartridge system operates in 4 phases, Vault fill and Air Release, Uniform Bed load hydrodynamic filtration, Uniform Bed load siphon filtration and Siphon break and hydrodynamic backwash.

BayFilter systems are designed to be offline systems and can be designed for the water quality flow or volume. Each configuration should be evaluated to determine the best utilization. Each BayFilter system relies on a collection of individual cartridges to achieve the desired removal efficiency so the correct number of cartridges is important. 3 factors are important when determining the number of cartridges, flow capacity of the system, treated sediment load and jurisdiction.

Many options for configurations are available, the most common being manhole filter, precast vault filter and cast-in-place filter. Treatment capacity charts for manhole size and vault size are provided.

Installation of the BayFilter system can be performed by the same contractor performing the installation of piping and underground utilities. The installation process is very simple and consistent whether installing manhole, precast vault or cast-in-place vault.

As with all stormwater treatment devices the BayFilter systems requires periodic maintenance to continue operating at the design flow rate and efficiency. Maintenance involves the removal and replacement of each cartridge and cleaning of the containment system with a vacuum truck. Maintenance should be performed by trained personnel on a cycle dictated by the solid loads on the filter.

Specifications clarifies internal components, performance factors and installation. A manhole configuration and Vault configuration diagrams with a load capacity chart included.
