Lagoon sludge management with sludge map

HOME    GEOTUBE    Lagoon sludge management with sludge map

 

Creating a sludge map is an important first step to improving lagoon management and can reveal critical information about the volume of sludge and how it’s distributed throughout the treatment cells.

 

Our sludge mapping team often finds that sludge depth is significantly different than what operators expected and that it’s unevenly distributed in lagoon cells. These factors alone can cause a number of problems in lagoon operation such as insufficient treatment capacity and retention time, flow impediment, short circuiting, and inadequate removal of BOD, TSS and/or ammonia.

 

 You need tests the sludge to determine the proper polymer dose rate before pumping sludge to the Geotube dewatering containers.

 

But once the information is in hand, operators and utilities managers can benchmark the current sludge situation and make informed decisions on a number of sludge management actions including:

 

Current and required lagoon capacity;

How much sludge to remove and from which areas of the lagoon;

How often sludge should be removed;

Budget planning for removal.

 

Depending on the results, lagoon operators may decide to cleanout the entire lagoon, or remove sludge only from areas of concern.

With advanced hydraulic dredge enables lagoon cleanout to occur while the facility remains in operation and our onsite dewatering capabilities—using Geotube containers—dramatically reduces the cost of sludge disposal and truck traffic.
