Whole House carbon & Gravel Multi-Media Filters (MMF) are an efficient, economical method for removing suspended solids from Municipal water In low TSS streams, they can be used for primary treatment. They are an excellent method of secondary treatment after a primary treatment such as an inclined Cartridges..
HOW IT WORKS
The incoming waste stream is equally split and enters the top of the filter vessels. As the Municipal water travels downward through the filter media, the solids become trapped in the media bed while the water passes through. The clean effluent exits through an outlet header for further treatment or discharge. As the solids build on the media, the pressure of inside the filter builds. At a certain pressure, the media has reached a loading capacity and needs to be back washed. The backwash mode reverses the flow of the water through one filter at a time. The water enters the bottom of the vessel which expands the filter media and releases the captured solids. Once all the vessels are back washed, the filter is back to its original filtration capacity.
- Captures 99% or more of particle 1 microns or larger
- Standard Triple Cell design provide the best flux rate for filtration and backwash operation
- 5 layers of media provides better filtration capacity which requires less backwashing
- No consumable costs such as filter cartridges
- Skid mounted design with manual, electrically actuated, or pneumatically actuated vavles
- Vessels constructed of FRP.
- Flow ranges from 5 - 1000 GPM.
