GZXZEP Low-Temperature Microbial Consortium is a cold-adapted bioaugmentation culture developed for wastewater treatment under reduced water temperatures. Its selected microorganisms retain biological activity in cold conditions, helping sustain organic-matter degradation, ammonia conversion and process recovery during seasonal temperature decline.
It is widely used in wastewater plants in cold regions, winter and early-spring biological treatment, low-temperature industrial wastewater and systems with seasonal ammonia-removal deterioration.

• Active in the 5–15 °C range according to the product catalog. • Supports winter nitrification and organic removal. • Shortens low-temperature acclimation. • Suitable for seasonal reinforcement before winter.

• Wastewater plants in cold regions. • Winter and early-spring biological treatment. • Low-temperature industrial wastewater. • Systems with seasonal ammonia-removal decline.

• Model: XZ8811 in the supplied table; model code duplicates the COD-degrading culture and must be confirmed before publication. • Form: Powder. • Viable cell count: ≥1.0×10¹⁰ CFU/g. • Operating range: 5–15 °C according to catalog data. • Dosing point: Biological or aeration tank.

1. Cold-adapted organisms maintain enzyme activity at low temperature. 2. The added culture strengthens winter microbial metabolism. 3. Performance depends on oxygen, pH, sludge age and gradual acclimation.

• Packaging: 25 kg moisture-resistant bag. • Storage: Store sealed in a cool, dry and shaded place. Protect from moisture, heat and direct sunlight. • Reseal opened bags immediately to prevent moisture uptake and contamination.

• Customized formulation — The strain combination, activation method and dosage plan are selected according to pollutants, biological process, temperature and loading. This normally provides better treatment performance and overall cost efficiency than a one-formulation-for-all product. • In-house manufacturing — Competitive factory pricing, stable batch quality and fast lead times. • In-house laboratory — Rapid sample testing, formulation screening and continuous product improvement. • Engineering support — Professional engineers provide product selection, dosing, commissioning and after-sales troubleshooting support.
