SCONSA Flocculation Filter Tanks

Applications

The Floc Tanks available for rental from SCONSA Environmental Services Limited are designed to be used in conjunction with other technology and systems available from SCONSA, such as dewatering tubes.

Water with a high sediment content (above 5% should ideally be pumped through a dewatering tube to allow the Floc Tanks to operate efficiently.

Capacity

Each floc tank will treat up to 40 litres of sediment laden water per second. The Floc Tanks can be joined together to increase the capacity and mixing time if required.

Reduced Waste

The large particles settle quickly to the bottom of the Floc Tank and becomes a slurry. This slurry can then be pumped into a dewatering tube to ensure that minimal amounts of water are removed around or off site, thus saving cost and reducing the carbon footprint of the operation.

Mobile Filtration Tanks

SCONSA Environmental Services Floc-Tanks are built on a roll-on - roll off skid to allow ease of transportation, especially in confined areas and uneasy terrain. The Floc-Tanks also have lifting eyes for movement by excavator or crane. Floc-Tanks can be used individually or can be joined together in-line to increase the capacity required depending on the sites requirements.

How the System Works

Water is pumped into the tanks through an integrated bauer coupling located at the back of the tank. The then moves through a launder pipe built into the tank. The launder is installed with a gradient drop to allow the turbid water to flow through it. Located within the launder pipe are caged chambers where the floc logs are placed. The water is moved around the top of the tank and then discharged into the main body of the tank where the larger sediment particles settle quickly to the bottom and the particles still in suspension are caught in the baffle screens.

Baffle Screens

Baffle panels are constructed of layers of geotextile fabric attached to a steel frame.  Series of these frames are placed upright, perpendicular to the flow of water inside the Floc Tank and are supported by a channel to ensure stability and ease of installation and removal.  The water, after being treated with the Floc Logs, passes through the baffle grid, where the treated sediment in captured by the fabric, allowing the clarified water to pass through. The baffle grid does not reduce the water flow as it does not act as a filter.
The baffle screens are changed as required to and a new section of baffle material placed inside the supporting frame.

 

Particles trapped

As the water passes through the tank the particles are trapped in the screen. At the end of the tank, a baffle plate ensures that the water level inside the tank to increase. Once the water exceeds the baffle plate level, it cascades into a final chamber where the water is discharged through two 8 inch bauer coupling outlets. The baffle plate is designed to prevent the sediment build up from backing up behind the sludge release coupling. This coupling is used when the tanks are cleaned for transporting the sludge either back to the dewatering tube or into a tanker for disposal. Each floc tank will treat up to 40 litres of sediment laden water per second.
