Formula 25DW - Bacteria supplement for dairy/milk processing waste

Dairy or milk wastewater often has high organic load, high nutrient content, high suspended solids, and variable flow rates. Wastewater processing can be challenging because of the diversity of organic waste in the system and the use of cleaning agents.

Formula 25DW contains specially selected microorganisms and a micronutrient blend formulated to accelerate the breakdown and metabolization of organic components when treating liquid and solid manure and wastewater from milk rooms, holding areas and barns.

Dosage rate will vary with flow rates, retention times and system variations.

Do not add to the treatment system at a location where toxic or otherwise adverse pH, dissolved oxygen or temperature conditions may exist at peak levels.

For optimal results the wastewater and treatment system should meet the following conditions:
Optimum Minimum
Influent pH 7.0 5.0
Dissolved oxygen, ppm 2.0+ 1.0+
C/N/P ratio 100/10/1 100/5/1
Temperature 30°C (86°F) 10°C (50°F)
Toxic metals, ppm
(E.g., hex., chromium)
0 0
