Characteristics of wastewater from biofuel production

Abstract

Wastewater is water contaminated with waste from industrial or agricultural production and household waste. Wastewater also includes water that is formed as a result of atmospheric precipitation within settlements and industrial facilities, sometimes called stormwater runoff. Wastewater treatment is the treatment for destroying or removing harmful pollutants from it. According to the degree of aggressiveness, wastewater is divided into weakly aggressive (slightly acidic with pH = 6-6.5 and weakly alkaline with pH = 8-9); strongly aggressive (strongly acidic with pH < 6 and strongly alkaline with pH > 9) and non-aggressive (with pH = 6.5-8).
