Wastewater treatment plan at VINA Company
After the inspection of the wastewater treatment system of VINA animal feed factory, Microbe-Lift technical team proposed to use two types of microorganisms in combination to treat ammonia and stabilize the performance of the whole system.
- Microbe-Lift IND microorganisms treat organic compounds to facilitate the optimal Ammonia Nitrification process. At the same time, stabilize the overall system performance.
- Microbe-Lift N1 adds Nitrobacter and Nitrosomonas to promote and enhance the ammonia treatment process.
Two strains of probiotics were added to the aerobic biological tank. Microbe-Lift IND probiotics were added 7-10 days in advance, followed by Microbe-Lift N1 probiotics.
For a system with a capacity of 50m3/day and night, the recommended dosage of microorganisms is 2 gallons of Microbe-Lift IND and 2 gallons of Microbe-Lift N1. (1 bottle = 1 gallon = 3.785 liters).
Results after using Microbe-Lift IND and Microbe-Lift N1 in combination
After 30 days of use, the Ammonia index has met the discharge standard. From 37.6 mg/l reduced to 4.2 mg/l, the treatment efficiency is 88% when adding Microbe-Lift N1 and Microbe-Lift IND Ammonia treatment microorganisms.
