Oxygen supply power for the tradition of sludge aerobic digestion process (cad) high cost, need to add chemicals (such as lime) and adjust the ph value so as to further increase the cost of processing conditions without increasing the infrastructure costs, the original sludge aerobic digestion proce

For traditional sludge aerobic digestion process (CAD) exist in high-cost power supply of oxygen, you need to add chemicals, such as lime) to adjust pH value so as to further increase the cost of disposal is not an increase in infrastructure costs, the conditions of the original sludge aerobic diges

Is high in view of the traditional sludge good oxygen digestion craft (CAD) existence for the oxygen power cost, thus needs to increase the chemical agent (like lime) to adjust the pH value further to increase the processing expense the question, in does not increase the capital construction expense

For traditional sludge good oxygen digestive technology (CAD) exists of for oxygen power costs high, needs added chemical pharmaceutical (as lime) Regulation pH value to further increased processing costs of problem, in does not increased infrastructure costs of conditions Xia, on original of sludge
