Eco Pond Rescues WaterWagon Demonstration at Reedy Creek Environmental District November 11, 2010
The Facts Pumped at 500 GPM Total of 9 LIPVAC Floc Logs used –8 in PAM Cannon –1 in Tank Pumping began between 11:15 and 11:30 a.m. Pumping stopped and wagon drained between 16:18 and 16:37
WaterWagon portable polymer enhanced water clarification system
The WaterWagon uses the Floctopus to facilitate mixing of the turbid water with the LIPVAC Floc Logs. The Floctopus is a multi-pipe apparatus that enables LIPVAC Floc Logs to react with the turbid water to flocculate out sediment.
Turbid water from the pond is pumped into the WaterWagon.
Water is pumped from the pond to the Floctopus to react with the LIPVAC Floc Logs. Then the treated water moves to the serpentine baffle.
LIPVAC Floc Logs are installed in the Floctopus on the top of the WaterWagon.
Treated water is discharged into tanks before emptying into the serpentine baffle. This tank also serves as a place for additional logs to be inserted if necessary.
The serpentine baffle chamber with natural fiber matting allows for 3 minutes of contact time to capture flocculated particulate.
Notice how the water is higher on the left and lower on the right. This is to make sure that the flocculated particulate has been captured and the water being discharged is as clear as possible.
Natural fiber matting is used in the serpentine baffle to provide a surface for the flocculated particulate to adhere to.
Water discharges out of top 3. Bottom two are for cleaning and are only opened up if the system gets backed up and additional discharge points are necessary.
Polymer charged jute matting is spread after the discharge point of the WaterWagon to capture the fine sediment that has not settled out of the water column.
The initial turbidity values started at 200-300 NTU. Within 5 minutes of turning on the systems, the discharge turbidity level was at 17 NTU.
Treated water is discharged back into the pond.
Look at the clarity of the water being discharged back into the pond.
See how the flocculated particulate has attached to the natural fiber matting in the serpentine baffle.
After removing the sediment laden matting out of the baffle the NTU jumped form 10 to 100 at the discharge point. At that point the meter was shaken and some sediment fell off bringing the NTU value down into the 30s.
This piece of matting was located at the first corner of the serpentine baffle.
This piece of matting was located at the third corner of the baffle.
Towards the end of the day, even after removing the matting from the baffle the NTU value was only 16.
Flocculated particulate has attached to the jute matting after the discharge point and before the water re-entered the pond.
In areas on the tarp at the discharge of the WaterWagon it is easy to see the flocculated sediment in the small pools of water.
This is the jute matting that was in the tank immediately after the Floc Logs. As you can see the flocculated sediment is already attaching to the jute. At this point the jute is removed for the remainder of the demonstration.
At the end of the day the discharge NTU jumped to 18.5 from 14.
