Refinery Wastewater Pond Cleanup with Remote Dredging

We recently completed the cleanup of two wastewater ponds for a large producer of transportation fuels. Using a remotely controlled dredge, Brennan removed wastewater sludge from impoundments on the refinery site and dewatered the material with six 2-meter belt filter presses. The remotely controlled dredge added a layer of safety to the project, preventing any health risks that a Leverman might face if exposed to hydrogen sulfide gas released during the dredging process.

What Is Treatability: An Important Asset in Environmental Dredging

Posted by Amber Wilson on February 29, 2024

Treatability testing uses bench-scale demonstrations and analysis to determine if a material can be effectively treated with a specific chemical or process. At Brennan, we use treatability testing to develop sound technical approaches for dredged material dewatering, in situ or dewatered dredged material stabilization, and water treatment. 

Treatability data can be used to price a job more accurately and find cost savings for our clients. Treatability testing allows us to select chemical and mechanical processes for treatment and evaluate less costly alternatives. Here's how we do it.
