  Laboratory investigations of aluminium (PAX-16) application for control of population of filamentous bacteria Microthrix Parvicella in a three-phase bioreactor in lab-scale were performed. Dosing of small aluminium doses (approximately 0.5 mgAl/gMLSS·d) in the period preceding seasonal growth of M.Parvicella failed to prevent mass growth of this microorganism leading to activated sludge bulking phenomenon (SVI-250 ml/gMLSS)...

  The phenomenon of potassium efflux (GGKE - glutathione-gated potassium efflux) from the calls of activated sludge bacteria in the result of peroxyacetic acid (CH3CO3H) dosing was investigated. Addition of the strong oxidant to the activated sludge environment caused activation of the defense mechanisms of bacterial cells, related to glutathione transformations, which resulted in the significant increase of potassium ions concentration....
