Built Around Your Operation

What does your plant need right now?

Choose a service to see how Merrell Bros. can help protect capacity, reduce disruption, and keep your operation moving.

01 | Mobile Belt Press Rentals

When your system cannot keep up, waiting is not an option.

Biosolids keep coming even when capacity drops, equipment goes offline, or a project creates a temporary surge. Storage fills. Schedules tighten. Your team spends more time managing the problem and less time running the plant.

Merrell Bros. brings proven mobile dewatering equipment directly to your site. Our fleet can be configured around your material, throughput, footprint, and schedule, giving you the capacity you need without the cost and commitment of purchasing permanent equipment.

Operational in as little as 2 to 4 hours Mobile equipment, experienced support, and a setup designed around your site.

02 | Mobile Control Offices & Temporary Enclosures

The project keeps moving. Your team and equipment should be ready for it.

Cold weather, limited visibility, and long shifts can make an already demanding dewatering project harder. Merrell Bros. adds protection, control, and a comfortable workspace directly at the job site.

Temporary Enclosures

Freezing conditions should not put your schedule on ice. Custom enclosures protect equipment and help dewatering continue efficiently through cold weather.

  • Built to fit equipment of virtually any size
  • Quick installation to reduce disruption
  • Custom configurations for the project
  • Optional 3-phase, 480V heating

03 | Lagoon Cleaning

Sludge buildup quietly takes away the capacity you depend on.

As sediment accumulates, treatment efficiency falls, odors increase, compliance becomes harder, and the risk of expensive repairs grows. Waiting does not make the material disappear. It gives the problem more time to grow.

Merrell Bros. cleans and restores municipal, industrial, and agricultural lagoons of every shape and size. We evaluate the material, lagoon depth, operational limits, and disposal plan, then select the method that gives you the right balance of efficiency, control, and minimal disruption.

  • Recover valuable lagoon capacity
  • Improve treatment efficiency
  • Support environmental compliance
  • Reduce odors and future repair risk
Restore your lagoon's performance
01

Hydraulic Dredging

Powerful suction and specialized cutter heads remove soft sediment through a pipeline while leaving the lagoon largely in operation.

  • Ideal for large or deep lagoons
  • Effective on silt, clay, and organic sludge
  • Minimal surface and facility disruption
02

Mechanical Dredging

Excavators, backhoes, and specialized equipment remove heavier, compacted material where precision and direct excavation are needed.

  • Handles rocks, debris, and dense sediment
  • Effective in shallow or smaller lagoons
  • Supports complete lagoon dewatering

04 | Hauling & Transportation

When biosolids stop moving, the pressure spreads everywhere.

Storage fills. Flexibility disappears. Planned logistics become emergency coordination, and your team is pulled away from plant performance. Reliable hauling is not simply transportation. It is what keeps the rest of your operation predictable.

05 | Digester & Tank Cleaning

Digesters and tanks do not lose performance overnight. They quietly fill up.

Grit, sand, rags, scum, and settled solids steal the space your process depends on. Mixing weakens. Capacity drops. Equipment works harder. Meanwhile, the daily flow keeps coming.

A planned cleanout restores more than volume. It brings back breathing room, protects equipment, improves process performance, and reduces the risk of an expensive unplanned shutdown. Merrell Bros. scopes the work around your layout, access, and operating limits, then brings the crews and equipment to complete it safely.
