Aqua Aerobics AquaDiamond Cloth Media Filter is a unique combination of two proven technologies; traveling bridge and cloth media filters. The result in up to 3x the flow capacity of a traveling bridge filter within an equivalent footprint, making it ideal for sand filter retrofits.
Why Cloth Media?
It’s not just “hydraulic loading” rate, but also “solids loading” rate that matters for an effective Tertiary Device (especially when filtering TSS and precipitated phosphorus solids).
The cloth media is completely submerged during filtration where solids are deposited on the outside of the cloth as the influent wastewater flows through the media. The filtered effluent is collected inside the diamond lateral and flows by gravity on to discharge. The filtration process requires no moving parts.
Increased headloss due to the deposited solids automatically initiates periodic backwashing. During backwash, a pump provides suction to the backwash shoes, which make direct contact with the media, allowing solids to be vacuumed from the cloth as the platform traverses the length of the diamond laterals.
The platform operates only during backwashing and solids collection. Because of the vertical orientation of the media, some solids will settle to the basin floor during normal operation. Small suction headers provide a means for collecting and discharging the settled solids. The solids collection process utilizes the backwash pump for suction.
