River Restoration: Small Dredges Prove Useful in Waterways

Posted by Paul Olander, Senior Project Manager on March 25, 2020

As the sun on the dredging season in the Midwest inland areas began to set, operations were starting to heat up on the east coast for J.F. Brennan Company (Brennan). For a third straight year, Brennan has had the opportunity to procure work in the milder maritime climate throughout New England during the winter months. These months are key for in-water work on the east coast as they provide opportunities to revitalize salt marshes, re-nourish beaches and restore navigation outside of the fish migration and spawning windows. Generally, this work has been undertaken in and near the coastal salt marshes adjacent to the smaller resort communities.

The Basics of Using Polymers on Dredging Projects

Posted by Dillon Hogan on October 16, 2018

Why Add Polymers?

 

One of the biggest challenges on a dredging project is managing the water that is excavated and transported with the sediment. On hydraulic dredging jobs where sediment and water are pumped through a pipeline as a slurry, water can account for 90+ percent of the volumetric flow. After the slurry reaches the disposal area, the water must be separated from the sediment, collected, and often clarified or treated. This process must happen as fast as the water is being pumped, which for a 12-inch cutterhead dredge could be 5,000 gallons per minute.
