Additional information

The field data of the manufacturer's waste water treatment plant indicates that betaine is not toxic to activated sludge microorganisms. Waste waters resulting from the manufacturing process of this substance are treated in low-rate activated sludge treatment plant at manufacturing site. Based on the annual monitoring results, this substance at average influent concentrations of 0.079 g/l is not an inhibitory to activated sludge microorganisms. The substance contains nitrogen yeilding ammonia/ammonium during the degradation process. However, nitrogen present in the substance can be efficiently removed during waste water treatment. The removal efficiency of total nitrogen is 93 %,and respectively 95 % of ammonium. After treatment, the effluents can be discharged into the sea.
