Notes:
Mixed cultures of microorganisms immobilized on sand were used to degrade s-triazine-containing industrial wastewater in a fluidized bed reactor. Immobilized cell concentrations of up to 18 g/L volatile suspended solids could be achieved with the s-triazines as sole nitrogen source for growth and carbon sources added at a C—N ratio of about 12. Maximal removal efficiencies of 80% of the s-triazines could be maintained only if (a) the bio-film thickness was limited to avoid oxygen deficiency and (b) the carbon source and complete wastewater (≤50% v/v in the feed) were supplied continuously at a mean hydraulic residence time of ≥20-25 h.
