Low Temperature (LT) is a blend of cold weather Bacillus bacteria designed for reliable performance when water drops below 15°C/60°F. While standard bacteria lose efficiency in cold weather, strains in LT retain up to 90% biological activity at 4°C/39°F, providing effective winter wastewater treatment for plants and lagoons, and supporting pond maintenance where cold weather slows natural biology. By reducing sludge buildup and supporting nutrient balance, LT helps operators avoid seasonal disruptions and ensures a smooth handoff into spring operations.

  • High Cold-Weather Activity: Maintains ~90% biological performance at 4 °C/39 °F for effective BOD, COD, TSS, and sludge removal.
  • Rapid System Recovery: Provides reliable low temperature bioaugmentation to speed recovery from winter upsets that normally take 2–3x longer to stabilize
  • Nutrient & Sludge Control: Limits winter sludge accumulation and nitrogen/phosphorus release that trigger odors, TSS spikes, and algae growth in spring.
  • Hydraulic Resilience: Protects against washout and fluctuating flows during storms and variable loading.
  • Year-Round Reliability: Strengthens winter stability while ensuring continuity from cold-weather operations to spring startup.

Cold weather creates major challenges for wastewater systems of all types, from municipal and industrial plants to lagoons and ponds. Lower temperatures slow biological conversion and accelerate sludge buildup, creating seasonal risks. LT addresses these issues by supplying a tailored consortium of low temperature wastewater treatment bacteria that remain active and resilient when conventional microbes become sluggish.

Formulated to enhance activated sludge cold weather performance, lagoons, and biological nutrient removal systems, LT supports consistent BOD reduction at low temperature, reliable COD reduction in cold wastewater, and more stable ammonia removal and denitrification cycles. Its cold-active strains help maintain effluent clarity, reduce odor, and limit the seasonal sludge accumulation that typically disrupts operations in spring.


Enhances Winter Wastewater Treatment

LT is engineered to perform in cold environments across municipal and industrial wastewater systems. Its cold-active microbial strains deliver dependable results where conventional bioaugmentation products slow down.

  • Retains ~90% activity at 4 °C/39 °F for effective cold-weather treatment
  • Maintains BOD, COD, TSS, and sludge removal under winter conditions
  • Supports stable treatment in WWTPs, lagoons, and pond systems

Sludge Digestion and Nutrient Control at Low Temperatures

By limiting excess solids buildup during winter, LT helps prevent nutrient surges that cause springtime process problems.

  • Prevents nitrogen and phosphorus release that drive odors and algae blooms
  • Reduces sludge handling and hauling costs
  • Minimizes effluent upsets tied to seasonal load changes

Improves Plant Stability and Recovery

LT strengthens cold-weather process resilience, keeping operations stable and helping facilities recover faster from upsets.

  • Supports rapid recovery when winter disruptions occur (up to 2–3× faster stabilization)
  • Reduces vulnerability to hydraulic washout during storms and variable flows
  • Works synergistically with existing biomass for balanced microbial communities
