Wastewater Treatment Solutions

Get Your Wastewater Treatment Under Control

If turbidity or influent loading levels are inconsistent, sludge costs are climbing, or your system feels unstable, you need more than a chemical swap. Garratt-Callahan helps industrial facilities improve wastewater performance with practical, proven treatment programs and expert support.

Practical Improvements You Can Measure

When wastewater performance slips, the impact goes beyond turbidity control —it shows up in operating costs, energy use, water consumption, and sustainability targets that are harder to meet.

Our role is to help your team restore stability and improve wastewater management and performance with treatment programs built for real operating conditions—not trial-and-error adjustments. Teams rely on us to: 

  • Improve clarification and solid liquid separation (SLS)
  • Increase dewatering effectiveness
  • Reduce sludge volume and control disposal costs
  • Stabilize treatment results under changing conditions
  • Prevent downtime and maintain reliable operations
  • Monitor and enhance biological treatment systems

Common Wastewater Challenges We Solve

Wastewater issues rarely start as a major failure. They usually show up as small performance swings that turn into rising costs, inconsistent results, and growing operational risk. If your team is dealing with any of the challenges below, we can help you evaluate what’s happening and identify the most effective wastewater treatment solutions to move forward.

Clarification

Dewatering

Performance

When solids don’t settle in a clarifier or float in a DAF consistently, downstream issues and rework pile up fast.

Dewatering inefficiency usually shows up in higher polymer use and rising disposal costs.

Even small changes in influent or operations can cause wastewater performance to decline over time.

  • Carryover & inconsistent solids removal rates
  • Clarifier performance varies by shift/day
  • More operator time spent troubleshooting
  • Polymer usage climbs without improvement
  • Wetter cake/inconsistent dewatering performance
  • Sludge volume driving higher hauling frequency and costs
  • Results change as loads vary or production shifts
  • Adjustments help temporarily, then performance slides
  • Systems feels sensitive & hard to “hold steady”

Why It Matters:
Reduced throughput, unpredictable results & potential violations

Why It Matters:
Higher cost per gallon treated

Why It Matters:
Greater downtime risk & ongoing instability

A Wastewater Program Built for Stable Results

Wastewater treatment isn’t solved by guessing—or by changing one product at a time. We help you stabilize performance with a practical treatment approach designed for real operating conditions.

What you can expect:

  • A clear treatment recommendation tailored to your system and goals
  • Coagulation and flocculation programs selected for performance and consistency
  • Guidance on feed strategy and optimization to improve repeatability
  • Support to reduce variability and prevent performance drift over time

The goal is stable results you can maintain—not constant adjustment
