Anaerobic Treatment of Liquid Waste
Anaerobic Treatment of Liquid Waste

In a reactor, optimum ,acid, to alkalinity ratio is between 0.1 and 0.5; buffers work to keep the ,acid,/alkalinity ratio in this range. This is done by adding various chemicals, like caustic or magnesium hydroxide, to keep the alkalinity high enough to offset the microbial community’s ,acid, production.
