INTRODUCTION ....... 2 BAYFILTER ........3 BASIC PRINCIPLES OF FILTRATION.
Page 3: Bayfilter
A BayFilter System is typically a concrete structure (precast vault, manhole, or cast in place structure) with a single or multiple BayFilter cartridges. Inside the structure the BayFilters are connected to an outlet manifold through which the treated water exits the system.
Page 4: Basic Principles Of Filtration
At BaySaver we believe it is our responsibility to engineer a balance within these variables to provide effective stormwater treatment at an exceptional value to our clients.
Page 5 The sediment loading capacity of the BayFilter is 350 pounds (158.7 kg) for the 45 gpm (170.3 lpm) and 30 gpm (113.6 lpm) cartridges. Surface area and loading rate contribute significantly to filter longevity.

Page 8: Bayfilter Operation
BayFilter driven by a hydrostatic head. Within the BayFilter, the water flows through a proprietary filter media and drains via a vertical pipe. The vertical pipe is connected to the under drain system, which conveys filtered water to the outfall.
Page 9 Dislodged particles are transported back in to the filter vault and accumulate on the filter vault floor. Each BayFilter has a maximum flow rating. At this flow, each cartridge can treat the specified total sediment load before requiring maintenance. BayFilter flow may also be custom regulated to meet specified design parameters by modifying the flow control orifice.
Page 10: System Design & Sizing
Schematics of off-line BayFilter systems are shown below. In Figure 1, the bypass structure diverts treatment flows to the BayFilter system and allows high flows to pass to a separate outfall. The bypass structure will feature flow controls designed by an engineer to ensure that the required treatment flows are sent to the BayFilter.
Page 11 A BayFilter system must be installed in an area that is accessible to maintenance equipment. The maintenance of a BayFilter system requires a vacuum truck as well as the removal and replacement of the filter cartridges.
Page 12 BayFilter series 500 BayFilter system sizing system sizing Table Each BayFilter system relies on a collection of individual BayFilter cartridges to achieve the desired removal Treatment Treatment BayFilter efficiency. Accurately determining the required Flow Rate Volume number of filters is important to efficient operation.
Page 13 BayFilter cartridges required to treat that flow using Equation 1. Equation 1 Refer to the product details for BayFilter flow rates. The minimum number of BayFilter cartridges is equal to the maximum treatment flow rate divided by , rounded up to the next whole number.

5. Have the soil bearing capacity verified by a licensed engineer for the required load bearing capacity. On solid subgrade, set the first section of the BayFilter manhole/ vault. 6. Check the level and elevation of the first section to ensure it is correct before adding any riser sections.
Page 16 13. Install the Bayfilter Vertical Drain Down Modules (VDDM) to the manifold system (if applicable). 14. Install a row of flow disks and the BayFilter cartridges. Place each cartridge so the handle points across the Flow Disc Filter Placement vault.
Page 17: Inspection & Maintenance
When the drain down exceeds the regulated standard, maintenance should be performed. When a BayFilter system is first installed, it is recommended that it be inspected every six (6) months. When the filter system exhibits flows below design levels the system should be maintained.
Page 18: Availability & Cost
BayFilter systems are available throughout the United States from BaySaver Technologies. Material, installation, and maintenance costs vary with location. For BayFilter pricing in your area, please contact BaySaver Technologies at 1-800-229-7283. BayFilter cartridges and outlet components can be shipped anywhere in the world. Manholes and precast vaults are also supplied by BaySaver Technologies as part of a complete stormwater filtration system.
Page 19 The stormwater filtration system’s cartridges shall have a treated sediment capacity for 80% TSS removal between 150-350 lbs (68-159 kg). When BayFilter is initially installed, we recommend that an inspection be performed on the system in the first six (6) months. After that, the inspection cycle typically falls into an annual pattern given normal storm occurrence and actual solids loads.
