Effect of methyl alcohol and ethylene glycol on the work of activated sludge.
The effect of methyl alcohol and ethylene glycol on the work of activated sludge grown in synthetic wastewater was investigated. Wastewater carrying these compounds could be purified by the activated sludge method, providing the concentration of methyl alcohol and glycol did not exceed 5,000 mg/l and 1,000 mg/l, respectively. At these values reduced purification efficiency, increased volumetric index of the sludge and changes in the structure of the activated sludge flocs could be observed.
