Dredge Dewatering for a Municipal Lagoon

A REGIONAL MUNICIPALITY was dredging a lagoon in preparation for upgrades. Our customer was contracted to dewater the dredged biosolids and enable the construction of the new system.

‍

PROBLEM:

The customer didn’t have enough make-down systems on hand to address the opportunity. Operators often turn down work or limit job throughput as they lack enough rigs, the rigs are wonky and creating bottlenecks, or both.

BEHIND THE SCENES:

Without a make-down system, the incumbent flocculant could not be applied to the sludge on the way to the geotextile. The operator was faced with finding a new strategy or turning down work.

SOLUTION:

‍SimpleFloc, CarboNet’s pre-activated, no make-down chemistry was chosen as a way to break the logjam. SimpleFloc arrives ready-to-use in plug-and-play tanks that pump directly into the line without requiring any additional gear.

• This removed the equipment bottleneck that would otherwise have scuttled the project.
• SimpleFloc’s NanoNet technology also reduced the requirement for PAM by 75%, adding margin to the project and reducing chemical use.
  

BOTTOM LINE:

SimpleFloc not only allowed our customer to take on new business and scale throughput, but delivered additional benefits:

• Crews were more efficient as they didn’t have to babysit make-down
• Merge and de-merge was nearly eliminated since no water was piped or transported to support PAM make-down
• Significantly less chemicals were introduced into the operating envelope, ensuring no permits were breached
• Crews enjoyed safer working conditions not having to deal with dry make-down dust or slips from emulsion slop

Chemistry to compete

CarboNet’s NanoNet platform generates flocculants, coagulants, and targeting agents that that adjust in real time to changing wastewater conditions—cutting cost, dose rates, labor, and emissions.
