Over 20 years of experience in the design of aerobic wastewater treatment plants have given wedotanks.comÂ® the know-how to design and construct the best precast concrete tanks and systems for both aerobic wastewater treatment plants and anaerobic wastewater treatment plants for nitrification/denitrification and biological Phosphorus removal.
Anaerobic means without oxygen. Anaerobic exercise consists of brief intense bursts of physical activity, such as weightlifting and sprints, where oxygen demand surpasses oxygen supply.While aerobic exercise relies on oxygen, anaerobic exercise is fueled by energy stored in your muscles through a process called glycolysis.Glycolysis is a method by which glycogen is broken down into glucose, also known as 'sugar' and is converted into energy.Glycolysis occurs in muscle cells during anaerobic exercise without the use of oxygen in order to produce energy quickly, thus producing lactic acid, which causes your muscles to fatigue.Lactic acid is a by-product of glycolysis and forms when your body breaks down glucose for energy when oxygen is low.lycolysis is a method by which glycogen is broken down into glucose, also known as 'sugar' and is converted into energy.
