Assessment of the degree of electrochemical treatment of sewage using biotesting

Studies were conducted on estimation of the toxicity levels in various oxygen-containing chlorine compounds formed during electrochemical treatment of sewage by using a culture isolated from activated sludge purifying antibiotic production waste. It was shown that the products formed during electrocatalytic treatment of solutions (concentration of NaCl 1.5-5 g/l, pH 2.0-12.0, volumetric current density up to 10 A/l) were not toxic and stimulated the growth of P. fluorescens.
