Recovery of Nitrification pharmaceutical company case study


Courtesy of Bio Systems Europe

One Sunday in May our weekend standby service received a telephone call from a pharmaceutical company who’s waste water treatment system had suffered a plant upset, thought to have occurred the previous day, resulting in the loss of nitrification. The standard to be maintained is 10 mg/l.

Because of the urgency of the situation our team traveled to the company that same day taking sufficient of our material EU1000 to recover nitrification and, because the cause of the upset was unknown, to carry out toxicity tests. These were set up with controls and allowed to run overnight. No inhibition was indicated and EU1000 dosing was completed in one dose. The results are shown on the following chart.
