Common Challenges

Why Digesters Fail

Anaerobic systems can deliver big savings, but small instabilities quickly snowball into sour reactors, lost gas, and costly downtime if left unchecked.

Organic overloads

Fluctuations in substrate composition, such as sudden increases in fats, oils, greases, or other high-strength waste loads can cause volatile fatty acid (VFA) accumulation and lower reactor pH . When this happens, methanogenic activity slows, leading to extended recovery times.

Toxic/inhibitive chemicals

Quaternary amine compounds, oxidative chemicals, and solvents can poison biology. Even trace amounts can derail treatment function. 

Foam and scum

Gas entrapment, blocked mixing, and carryover follow. One needs targeted chemistry and operating rules to keep caps from forming.

Low gas quality

High H2S, moisture, and siloxanes corrode assets and make biogas unusable.

Anaerobic Digestion & Biogas

Precise, data-driven control for dependable anaerobic digestion.

A healthy anaerobic digester is dependent on intricate balance between several microbial communities. When this microbial balance stays steady, energy flows, uptime improves, and wastewater becomes a renewable resource instead of a liability. That consistency doesn’t happen by chance; it comes from understanding how every variable in the system affects the overall system.

CRB Water helps maintain that balance by treating your reactor as a living system, not just equipment. Every variable—from micronutrients to feed rate—affects biological treatment function. We match micronutrients to your feedstocks, help control loading rates to prevent organic overloads, and train operators to recognize early signs of change.

Instead of reacting to problems after they occur, you gain a clear view of what’s happening inside the reactor. Continuous monitoring tracks process trends, while QuatShield and ChloroAway protect microbes from industrial cleaners that can throw the system off balance. Our Virtual Sieve Analysis shows how anaerobic granules grow and respond over time. Moreover, our biological H₂S control improvements protect engines and maintain gas quality.

Together, these programs create a complete feedback loop—anticipating issues, preventing upsets, and optimizing performance so your anaerobic reactor runs steadily, efficiently, and without surprises.

 

What we do

Programs Built to Keep Reactors Steady

 CRB Water optimizes anaerobic digestion treatment programs that balance nutrients, protect microbes, and give operators the tools to maintain gas output with confidence.

Load and Nutrient Balance

Maintain microbial function

We analyze influent COD loadings, and nutrient gaps, then build custom nutrient packages that keep methanogens active. Balanced loading and micronutrient support prevent souring and extend reactor stability.

  • COD and nutrient profiling
  • Custom nutrient blends
  • Safe ramp rates

Real-Time Monitoring

Spot issues early

Track alkalinity, VFAs, pH, and gas flow with automated checks. Clear guardrails and operator dashboards trigger simple actions that stop small problems from becoming full shutdowns.

  • KPI dashboards 
  • Alerts and playbooks
  • Audit-ready records

Microbial Protection

Defend against toxins

Cleaners and disinfectants like quaternary amine compounds can disturb delicate microbial balance. We apply QuatShield and ChloroAway to neutralize toxins before they harm microbes, keeping reactors stable through production swings.

  • Cleaner neutralization
  • Toxicity control 
  • Consistent microbial activity

Granule Health Tools

Prevent washout

Our Virtual Sieve Analysis gives early visibility into biomass health. Detect shifts in granule size so that corrective actions can be taken before washout reduces treatment efficiency.

  • Image-based analysis
  • Early warning signs
  • Stability insights

Upset Recovery

Rapid recovery of treatment function

When treatment systems sour, we provide stepwise recovery protocols. Targeted chemistry, nutrient dosing, and root-cause reviews help operators restore balance and avoid repeat upsets.

  • Recovery protocols 
  • Targeted dosing
  • Root-cause analysis

Benefits

The Value of Anaerobic Digestion Treatments

CRB Water’s anaerobic digestion treatments do more than protect microbial communities — they lower costs, increase renewable energy, and bring peace of mind to plant teams.

Key Benefits of Anaerobic Digestion Treatments:
Reliable Uptime

Data-driven monitoring, custom nutrients, and responsive support prevent reactor souring due to foam, or toxic events that would otherwise force shutdowns and halt production.

Optimized Biogas Yield

Balanced methanogen activity and protected granule growth lead to steady, high-quality methane that powers facilities and offsets energy costs.

Reduced Operating Costs

Stronger conversion lowers effluent COD, reduces hauling needs, and minimizes chemical supplementation — easing budgets and improving sustainability.

Enhanced System Stability

QuatShield, ChloroAway, and Virtual Sieve analysis tools defend biology against toxins and washout, giving operators confidence in daily operation.

Clean Compliance

Proactive oversight and audit-ready records reduce permit violations, surcharges, and regulatory fines tied to unstable wastewater treatment.
